Activation Process
Scanning the QR code in eSIM4’s activation email is one way to install. The email also lists details for manual entry, and iOS 17.4 or later can use its Direct Installation link. Finish the install over Wi-Fi before leaving for the US. In the US, roaming belongs on the eSIM4 line only, with data switching turned off.
Price
For a short US visit, 1 GB over 7 days costs $2.98, and nothing else on this page starts cheaper. Some plans add texts and call minutes, such as 5 GB with 50 SMS and 100 minutes for 30 days at $17.98. Going unlimited costs $9.98 for 3 days, while 30 days of it cost $66.98.
Pros
- Routes on T-Mobile, Verizon and U.S. Cellular, with 5G
- Plans include a real US phone number and SMS allowance
- Unlimited data available from 3 to 30 days
- 24/7 live chat support with human agents, not bots
- Up to 70% cheaper than roaming with your home UK, AU, or EU carrier
Cons
- First-time eSIM install takes 2 to 3 minutes
Saily
Runner-up from Nord Security
Saily is the eSIM brand from the NordVPN team. The app is clean, and the built-in VPN feature is useful given US public Wi-Fi at Starbucks and every US airport lounge is unencrypted.
Coverage
Saily does not name its network in the US.
Data Plans
| Data | Duration | Price |
|---|---|---|
| 1GB | 7 Days | $3.99 |
| 3GB | 30 Days | $8.99 |
| 5GB | 30 Days | $13.99 |
| 10GB | 30 Days | $22.99 |
| 20GB | 30 Days | $36.99 |
| Unlimited | 15 Days | $45.99 |
Activation Process
Saily’s Install eSIM button, inside its app, puts the US eSIM on your phone. If the button fails, type wbg.prod.ondemandconnectivity.com into the SM-DP+ field, then add your activation code. Activation is automatic once you reach the US. Saily’s help centre also says to switch off your main SIM and mobile data switching after landing.
Price
Saily costs more than eSIM4 on every matching US plan, by $1.01 or $2.01. The entry plan, 1 GB for a week, is $3.99. Per GB, its 20 GB / 30-day plan at $36.99 is Saily’s best deal, and all seven rivals here do better. Saily sells unlimited data from 5 days, priced $17.99.
Pros
- Built-in VPN feature useful for protecting Starbucks and hotel Wi-Fi logins
- Clean app with accurate real-time data-usage display
- Unlimited / 15 days plan is competitively priced at $45.99
Cons
- No US phone number, so US 2FA SMS codes will not arrive
- Highest price per GB on this page, $1.85 on the 20 GB plan
Nomad
Polished app for frequent travellers
Nomad is a mid-market eSIM brand aimed at frequent travellers. Its USA plans are straightforward, and the app is one of the better ones in this comparison for tracking real-time usage mid-trip.
Coverage
Nomad’s partners on the USA plan are AT&T and Verizon. 4G is available everywhere a traveller will realistically go, including the drive between LA and Las Vegas. 5G is active in NYC, LA, Chicago, Miami, San Francisco, Boston, and Atlanta.
Data Plans
| Data | Duration | Price |
|---|---|---|
| 1GB | 7 Days | $5.00 |
| 3GB | 30 Days | $6.00 |
| 5GB | 30 Days | $10.00 |
| 10GB | 30 Days | $15.00 |
| 20GB | 30 Days | $25.00 |
| 50GB | 30 Days | $30.00 |
| 75GB | 180 Days | $89.00 |
| 100GB | 365 Days | $120.00 |
| Unlimited | 3 Days | $11.00 |
| Unlimited | 5 Days | $16.00 |
Activation Process
Each Nomad plan needs its own eSIM install, and the US one should go on before the flight. Use the QR code from your purchase email, manual entry or the Nomad app. After arrival, Nomad needs the mobile data line and data roaming, then a restart. Some of Nomad’s providers also need an APN.
Price
Nomad has this page’s lowest price per GB, with 50 GB for 30 days at $30.00. The widest gap is 20 GB for 30 days, at $25.00, $9.98 below eSIM4. The 1 GB / 7-day plan runs the other way, $5.00 against eSIM4’s $2.98. Unlimited comes in 3, 5 or 7 days, from $11.00.
Pros
- Polished app with clear data-usage tracking and low-balance alerts
- One login works across 170+ countries, useful for US-Canada or US-Mexico trips
- 5G support on AT&T and Verizon
Cons
- Pricier than eSIM4 on the 1 GB / 7-day plan
- No US phone number or SMS allowance
Jetpac
Short 1-day plans, uneven long-stay value
Jetpac sells short plans from $6.00 for 3 GB over 1 day, which suits a NYC or Miami layover. Long-stay plans are less competitive.
Coverage
Jetpac’s help centre lists Verizon as its US network. 4G is available across every city and tourist region, including Times Square, the Vegas Strip, and the Miami Beach causeways.
Data Plans
| Data | Duration | Price |
|---|---|---|
| 1GB | 4 Days | $7.00 |
| 3GB | 7 Days | $7.99 |
| 5GB | 30 Days | $12.99 |
| 10GB | 30 Days | $30.00 |
| 15GB | 30 Days | $33.00 |
| 20GB | 30 Days | $35.00 |
| 30GB | 30 Days | $50.00 |
| 40GB | 30 Days | $60.00 |
| Unlimited | 10 Days | $55.00 |
Activation Process
An unused Jetpac pack stays in your account for 3 months from purchase, so you can buy ahead. Choose app install, the emailed QR code or manual codes, and keep the line off until you arrive. Landing is the moment to switch it on, with data roaming enabled and Jetpac chosen under Mobile Data.
Price
Jetpac’s week-long 3 GB pack is $7.99. eSIM4’s 5 GB / 30-day plan is $11.98, and Jetpac’s is $12.99. Per GB, the 40 GB / 30-day pack at $60.00 works out best. A 3-day unlimited pack costs $15.00, $5.02 more than eSIM4, and the 30-day version reaches $150.00.
Pros
- Short 1-day plans from $6.00
- Supports 150+ destinations with one account
- Includes complimentary travel-insurance perks on some plans
Cons
- Highest entry price on this page, $6.00 for 3 GB over 1 day
- No US phone number
GigSky
Old-school with Apple Travel integration
GigSky has been in eSIM since the Apple Watch days. Its biggest selling point is direct integration with Apple’s built-in Travel eSIM feature, which makes setup one tap on an iPhone 15 Pro or newer.
Coverage
GigSky does not name its US network.
Data Plans
| Data | Duration | Price |
|---|---|---|
| 1GB | 7 Days | $2.99 |
| 3GB | 15 Days | $8.49 |
| 5GB | 30 Days | $12.49 |
| 10GB | 30 Days | $21.49 |
| 50GB | 90 Days | $39.99 |
Activation Process

The GigSky line needs data roaming once you are in the US. Holders of an eligible Visa card may get complimentary GigSky data too.
Price
GigSky has this page’s lowest unlimited entry, 1 day for $3.49. Only one cent separates GigSky and eSIM4 on 1 GB for 7 days, where GigSky charges $2.99. GigSky’s 10-day unlimited plan is $32.49, which saves 49 cents on eSIM4. Slow travellers get 90 days on the 50 GB plan, at $39.99.
Pros
- One-tap Apple Travel integration on newer iPhones
- Lowest unlimited entry on this page, $3.49 for 1 day
- Works on older eSIM-capable iPhones, iPads, and the Apple Watch Ultra
Cons
- Slightly pricier than eSIM4 on most matching plans

aloSIM
Simple pricing, no surprises
aloSIM keeps things simple with flat, up-front pricing and a no-frills app. It’s a solid pick for first-time eSIM users who don’t want to compare a dozen options before a US trip.
Coverage
Routes through T-Mobile and Verizon. 4G LTE is available across every US city and tourist region.
Data Plans
| Data | Duration | Price |
|---|---|---|
| 1GB | 7 Days | $5.00 |
| 3GB | 30 Days | $9.00 |
| 5GB | 15 Days | $13.50 |
| 5GB | 30 Days | $14.00 |
| 10GB | 30 Days | $23.00 |
| 20GB | 30 Days | $37.00 |
Activation Process
Your aloSIM US package counts no days until the phone connects to a supported network there. That lets you install it from My eSIMs in the aloSIM app well ahead of the flight. On the day you fly, turn the eSIM and its data roaming on, and confirm alosim appears as the APN.
Price
Plans begin at $3.50, the price of 1 GB for one day. aloSIM’s 10 GB / 30-day plan is $23.00, with eSIM4 at $20.98 for the same data. The 50 GB plan suits short, heavy use, lasting 10 days for $31.00. With unlimited data, a day is $5.00 and a week $27.00.
Pros
- No app install needed, just a QR code
- Clean pricing with no hidden fees or top-up surprises
- Responsive email support inside 12 hours
Cons
- Unlimited costs more than eSIM4 at 3, 5 and 7 days
- No voice or SMS add-on available
Airalo
The original budget eSIM marketplace
Airalo launched the consumer eSIM marketplace and still has the biggest country catalogue. Its USA plan is called ‘Change’ and hits the budget sweet spot for short trips.
Coverage
Airalo partners with T-Mobile and Verizon for 4G across the country. 5G is available on mid-tier plans and above.
Data Plans
| Data | Duration | Price |
|---|---|---|
| 1GB | 3 Days | $4.00 |
| 3GB | 3 Days | $8.50 |
| 3GB | 7 Days | $9.00 |
| 5GB | 7 Days | $12.50 |

| 20GB | 15 Days | $36.00 |
| 20GB | 30 Days | $36.50 |
| 50GB | 30 Days | $42.00 |
Activation Process
Airalo orders, in the app or online, start with an account. Direct install works on iPhones and some Android models, and you start it from the app. If direct install fails, Airalo’s self-service offers a replacement profile, a refund or escalation. In the US, use the eSIM for data, with Data Roaming as the app instructs.
Price
Airalo’s 3-day, 1 GB plan opens the US range at $4.00. Wherever the plans match, eSIM4 comes in $1.02 or $1.52 lower. At $42.00, 50 GB over 30 days is Airalo’s largest plan. Unlimited begins with 3 days for $11.50 and tops out at $68.00 for 30 days. Bundles with calls begin at $6.00.
Pros
- Wide choice of plan sizes and lengths
- Huge user base means the app is well-tested and mature
- Top-ups are easy from inside the app while in-country

Price
The entry plan here is a single day of unlimited data for $3.84. Roamless beats eSIM4 on 10 days of unlimited, with $29.40 against $32.98. Capped plans run a little above eSIM4, such as 5 GB / 30 days at $13.45, $1.47 more. 50 GB is the ceiling, sold for 30 days at $41.95.

Before You Leave For The USA: What You Need To Know
The stuff the top-ranking USA travel guides skip.
Researched and verified against live sources. Every non-obvious claim links to its primary source.
North America eSIM plans now cover all three countries. But activation must happen in the US
As of May 2026, both T-Mobile and AT&T have launched purpose-built eSIM plans for international visitors covering the USA, Mexico, and Canada in a single product. T-Mobile’s US Pass eSIM runs from $25 (7 days) to $50 (30 days), includes unlimited data in the US and 5 GB of high-speed data in both Mexico and Canada.
AT&T’s rival product offers similar North America bundles. The catch: T-Mobile requires activation while physically inside the US.
You cannot download and activate the eSIM from your home country before travelling. Third-party eSIMs (Airalo, Saily, Nomad, eSIM4) do not share this restriction and can be pre-installed before departure, making them the recommended choice for travellers flying into Canada or Mexico first.
Ride-hailing is not uniform across North America. DiDi, Lyft, Uber, and Rappi all play different roles
Uber operates in most major US and Canadian cities, but Lyft is a strong competitor in the US and often cheaper for airport runs or shorter city trips. Always check both apps before booking.
In Mexico the picture is more complex: Nomadic Matt explicitly recommends DiDi or Uber over street taxis because prices are fixed, drivers are vetted, and you have a digital record of the journey. DiDi (owned by the Chinese ride-hailing giant) launched in Mexico in 2018 and has rapidly expanded; in some Mexican cities it undercuts Uber by 20, 30%.
Rappi (Colombian) operates as a food delivery and last-mile courier platform, not a traditional ride-hailing app, across major Mexican and some Canadian cities. Cabify covers upscale demand in Mexico City and Guadalajara.
Street taxis in Mexico City and Cancun should be booked via an app or at an official taxi rank. Never hailed on the street.
T-Mobile, AT&T, Verizon: Why Only Two Show Up on Travel eSIMs
The US has three national carriers. T-Mobile holds roughly 35% market share and the widest 5G footprint, AT&T sits at 27% with solid nationwide 4G/5G, and Verizon owns 34% with the strongest rural reach, according to TeleGeography’s 2025 mobile market summary.
Almost every travel eSIM routes on T-Mobile or AT&T. Verizon is absent from virtually every third-party travel eSIM, so if your trip runs through rural Montana, Wyoming, or deep-country Alaska, your data will go quiet long before a Verizon customer’s does, as Whistleout’s US coverage guide notes.
Yellowstone and Grand Canyon Kill Your Signal at the Gate
Expect zero useful signal inside most US National Parks. Yellowstone has working cell service at Old Faithful, Mammoth, and Canyon Village, and nothing for a 50-mile radius in every other direction, per SatelliteInternet.com’s national parks audit.
The Grand Canyon’s South Rim has patchy AT&T and Verizon near the visitor centre, and the North Rim has nothing. Download offline Google Maps and the official NPS app before you drive past the entrance gate.
Reddit’s r/nationalparks thread has first-hand reports of travellers losing signal for three straight days inside Yellowstone.
The iPhone 14 Onwards Sold In The US Has No SIM Tray
Every iPhone 14, 15, 16, and 17 sold in the US is eSIM only. There is no physical SIM slot at all on US-market Apple devices, a change Apple made in September 2022.
This matters for two reasons: eSIMs are the default US mobile path for American buyers, and if a relative in the US offers to ‘lend you a SIM’, they cannot. Foreign visitors arriving with their own unlocked international phone are unaffected.
Travel eSIMs install and activate normally, as Apple’s own support guide confirms.
Getting Around
Uber Beats Lyft Outside the Big Metros
Uber and Lyft both work in every major US city and most mid-size ones. Uber has deeper coverage and usually the cheaper fare, but Lyft’s service is often comparable in big metros, based on r/uber price comparisons.
Both require the eSIM connection to match a driver and in-app payment. Neither accepts cash.
Surge pricing during rain, concerts, or rush hour can double or triple the fare. Check the quoted price before you confirm the ride.
NYC Uses OMNY, LA Uses TAP, Chicago Uses Ventra
Public transit in NYC runs on OMNY, the tap-to-pay system on buses and subways, per MTA’s OMNY site. Just tap a contactless credit card, Apple Pay, or Google Pay at the turnstile.
A single ride is $2.90 and after 12 taps in a Monday-Sunday week you ride free. LA uses the TAP card on Metro rail and bus.
Chicago uses Ventra on the L and CTA buses, with contactless tap-to-pay also supported.
Money: How Payments Actually Work
Cards Everywhere, Cash for Rural America
The US dollar is the only currency accepted. Cards dominate: Visa, Mastercard, Amex, and Discover are accepted almost everywhere in 2026, including contactless tap-to-pay, per the Federal Reserve’s 2025 payments data.
Rural gas stations, small-town diners, and food trucks outside major cities can still be cash-only. ATMs are everywhere but charge $3 to $5 per withdrawal plus whatever your home bank adds.
Apple Pay and Google Pay Rule the Checkout
Apple Pay and Google Pay work at virtually every chain retailer, Starbucks, subway turnstile in NYC, and airport restaurant. Contactless is the default payment method in 2026, per PYMNTS’s 2025 mobile wallet tracker.
Load your cards into Wallet before you fly and you can often leave physical cards in your hotel safe. Some older gas-pump terminals still require chip-and-PIN and will reject Apple Pay at the pump.
Foreign Card Fees Cost $80 on a Two-Week Trip
Foreign transaction fees are a silent tax. Most standard US-issued and European-issued credit cards add 2.7 to 3% on every non-home-currency transaction, per WalletHub’s card fee survey.
Before you fly, check your card terms. If your current card charges the fee, get a no-foreign-fee card like Wise, Revolut, or a travel-specific credit card.
Over a two-week US trip spending $3,000, the fee difference is $80 to $90.
Apps to Install Before You Land
| App | Why | Cost | Platform |
|---|---|---|---|
| Uber | Rides in every major US city. Deeper coverage than Lyft outside metros. | Free, pay per ride | iOS / Android |
| Lyft | Secondary ride-hailing option. Frequently cheaper than Uber in NYC and Chicago. | Free | iOS / Android |
| Google Maps (offline US pack) | Download the offline map for every state you will drive through. Signal drops inside National Parks. | Free | iOS / Android |
| NPS National Parks | Official National Park Service app with offline park maps, trails, ranger alerts, and safety info. | Free | iOS / Android |
| Apple Wallet / Google Pay | Tap-to-pay on NYC OMNY, LA TAP, Chicago Ventra, and most retail. | Free | iOS / Android |
| Citymapper | Transit routing for NYC, Boston, DC, Chicago, LA, and San Francisco. Handles bus, subway, and Uber in one view. | Free | iOS / Android |
| Transit | Real-time bus and subway arrivals across 300+ US cities. Better bus data than Citymapper in secondary cities. | Free | iOS / Android |
How Much Data You Actually Need
The biggest mistake travellers make is underestimating the amount of data they need, then burning through a 1GB plan before lunch on day one. Here is what real activities consume per hour:
Data per hour by activity (lower is better)
| Profile | Activities | Per Day | Week Total | Suggested Plan |
|---|---|---|---|---|
| Light user | Maps, WhatsApp text, occasional check-in | 150 to 300 MB | 1 to 3 GB | eSIM4 1 GB / 7 days or 3 GB / 30 days |
| Standard tourist | Maps, Uber, social, photo uploads, some music streaming | 500 MB to 1 GB | 5 to 7 GB | eSIM4 5 GB / 7 days or 10 GB / 30 days |
| Heavy streamer | YouTube, Netflix, Twitch, FaceTime video on the road | 2 to 4 GB | 15 to 28 GB | eSIM4 Unlimited / 7 days or 20 GB / 30 days |
| Remote worker | Zoom meetings, Slack, hotspot to laptop, cloud sync | 3 to 6 GB | 20 to 40 GB | eSIM4 Unlimited / 15 or 30 days |
| Road-tripper (2 to 4 weeks) | Maps, podcasts, Airbnb photo uploads, occasional streaming | 1 to 2 GB | 8 to 14 GB | eSIM4 20 GB / 30 days or Unlimited / 15 days |
Activating Your eSIM on Arrival
Install and activate your eSIM before you board, not after you land. The single most common US eSIM failure mode is arriving at JFK or LAX, connecting to airport Wi-Fi, and having the Wi-Fi time out mid-install, based on dozens of reports on r/travel.
JFK’s free Wi-Fi is 30 minutes, LAX is 45 minutes, ORD is unlimited but throttled. SFO has the most reliable free airport Wi-Fi at arrivals.
Install over your home Wi-Fi before you fly, toggle airplane mode off on arrival, and the eSIM will attach to T-Mobile or AT&T within 60 seconds. If you have to install on arrival, do it in the arrivals hall Wi-Fi, not in the queue at passport control (the signal there is notoriously poor).
Every major US airport has T-Mobile or AT&T public 5G inside the terminal after you clear customs.
Phone Numbers and SMS
Most travel eSIMs for the USA are data-only. You will not get a US phone number.
This matters when a US merchant sends a SMS code to verify a card, or when a rental car company texts you the unlock code, or when a restaurant’s online wait-list sends a text when your table is ready. Workarounds: keep your home SIM active for incoming SMS via dual-SIM (iPhone and most modern Androids support it), use iMessage or FaceTime over the eSIM’s data, use WhatsApp for messaging Americans with WhatsApp installed (roughly 30% of the population), or get a virtual US number from Google Voice (free for US/Canada/UK citizens with an existing Google account) or from Wise, Revolut, or US Mobile’s $5-a-month plan for a real US number. ESIM4’s USA plans that include SMS and a phone number solve the 2FA problem out of the box, per eSIM4’s USA plan listing.
Emergency: 911 works on any active US connection, eSIM or not.
Where You Will Actually Use Your eSIM
- New York CityGoogle Maps on the subway between transfers, Uber after theatre, Open Table for dinner bookings in the West Village, and tap-to-pay through OMNY at every turnstile in Manhattan. 5G is ubiquitous on T-Mobile above ground; underground stations are getting 5G rolled out through 2026 but coverage is patchy on older lines.
- Los AngelesYou will burn data in traffic. Uber between LAX and Hollywood, Google Maps for the 45-minute drive to Santa Monica, Waze for traffic reroutes around the 405, and Apple Wallet for LA Metro TAP card. 5G is strong across Downtown, West LA, and Hollywood. Palos Verdes and the Malibu canyons are 4G at best.
- Yellowstone and the Grand CanyonYou will lose signal at the park entrance and not get it back until you drive out. Pre-download the NPS app, the offline Google Maps pack for Wyoming or Arizona, and any lodge or tour booking PDFs before you enter. A physical paper park map from the ranger station is still the most reliable navigation tool.
- Las VegasThe Strip has aggressive free casino Wi-Fi plus strong T-Mobile and AT&T 5G. You will use your eSIM for Uber between hotels, Ticketmaster for same-day shows, Yelp for off-Strip restaurants, and resort apps (MGM, Caesars, Wynn) for room keys and bookings. Data use is heavy because of photo and video uploads.
- MiamiUber to South Beach, OpenTable in Brickell, Google Maps for the Art Deco walking tour, and iMessage to family because everyone thinks you are at a pool party. Coverage is strong across Miami-Dade, Broward, and the Florida Keys. The drive to Key West on US-1 has a few 5-mile gaps on Big Pine Key and the Seven Mile Bridge.
- San FranciscoBART, Muni, cable cars, and every Uber ride from SFO to Fisherman’s Wharf will lean on the eSIM. 5G is excellent downtown and in Mission. Coverage drops in the fog-heavy parts of the Sunset District and inside the BART tunnels under the Bay.
- ChicagoCTA Ventra tap-to-pay at every L train turnstile, Uber after deep-dish at Lou Malnati’s, and Google Maps for the Magnificent Mile walk. T-Mobile 5G is strong across Downtown, Lincoln Park, and Wicker Park. Underground Blue Line stops to O’Hare have patchy data.
Frequently Asked Questions About eSIMs for the USA
What carriers offer eSIM in the USA?
T-Mobile, AT&T, and Verizon all support eSIM technology for their own customers. Travel eSIM providers like eSIM4, Saily, Airalo, Nomad, and Jetpac partner with T-Mobile and AT&T to sell prepaid USA eSIM plans to visitors.
Verizon rarely partners with third-party travel eSIM providers, so choose an eSIM that works on T-Mobile and AT&T for the best travel experience. ESIM4 uses both networks to keep you connected in cities and along interstate highways.
Which eSIM is best for the USA?
eSIM4 is the best eSIM for North America in 2026. It offers dual-network coverage on T-Mobile and AT&T, flexible data plans from $2.98, and an optional calling app making it one of the best eSIMs available for USA travel.
For security-conscious travelers, Saily’s NordVPN-backed eSIM service is the top alternative.
Do I need to register with my passport (KYC)?
Most travel eSIMs for the USA (like eSIM4, Airalo, Saily) do not require identity registration (KYC). You can simply buy, install the eSIM, and go no passport scan or ID verification required.
When should I install my eSIM?
Install the eSIM on your mobile phone before you fly to the USA. You can activate an eSIM on arrival, but installing it at home ensures you have internet access immediately upon landing no setup stress at the airport.
Can you get an eSIM for the USA and Canada?
Yes. North America eSIM plans from eSIM4 cover the USA, Canada, and Mexico with a single purchase. You do not need to use the same eSIM for all three countries, but regional plans mean no switching eSIMs at each border. The plan works across multiple countries so you can manage your eSIMs from one account for your entire North America trip.
Do I need WiFi to install a North America eSIM?
You need an internet connection to download and install the eSIM profile, so installing at home on WiFi is the easiest approach. You can also install at any international airport with free WiFi before you board. Once installed, the plan activates automatically when you land in North America. No need to purchase a local SIM or visit a carrier store on arrival.
