Saily

Security Focused

4.7/5
Coverage

Created by the team behind NordVPN, Saily is a robust choice tailored for security conscious travelers. It offers flexible plans covering a vast number of regions in Asia, ensuring you have internet access in both major cities and rural areas.

Coverage

Saily boasts impressive coverage spanning over 200 regions globally. In Asia, it connects reliably, though its broad focus means it lacks some of the specialized local carrier partnerships that defined our top pick’s value.

Usage

The service is managed entirely through a sleek app, emphasizing ease of use and digital safety. When you download the app, you can easily activate your plan. While intuitive, it remains a strictly data-only service, meaning you will need third-party apps like WhatsApp for all communication.

Customer Support

Support is handled via live chat and email. Responses are generally quick, leveraging the infrastructure of its parent company, though peak times can see delays.

Airalo

4.7/5
Coverage
Global
Support
In-app

Airalo is a well established provider known for its extensive regional plans. Their Asialink plan is perfect for travelers visiting multiple countries, offering a seamless connection without the need to switch eSIMs.

Coverage

Airalo’s “Asialink” package is a solid contender, covering multiple countries with a single eSIM. However, users should note that coverage in Oceania or Africa requires different regional plans. Users occasionally report slower speeds in less-touristed areas compared to providers with more aggressive local partnerships.

Usage

The Airalo app is polished and easy to navigate, allowing you to track data usage and top up. However, the setup process can sometimes require identity verification for certain regions, adding a step that isn’t present with our top choice. It’s one of the best esims for seamless travel.

Customer Support

Support is primarily accessible through the app or email. While competent, it lacks the immediacy of a dedicated 24/7 service line found with premium providers.

Rating

APAC
Support
Email

Nomad is ideal for those who consume a lot of data. With plans tailored for the Asia Pacific region (APAC), it offers large data bundles at competitive rates, making it a solid choice for digital nomads or heavy data users in places like Singapore or Hong Kong.

Coverage

Nomad focuses heavily on the APAC region, sometimes extending into Oceania. While coverage is decent in major cities, it can be spotty when venturing off the beaten path compared to the comprehensive reach of eSIM4.

Usage

The clean interface makes purchasing plans simple. However, users should be aware that it does not offer voice or SMS capabilities, restricting you solely to internet-based communication like WhatsApp.

Customer Support

Support is handled via a ticket system within the app or email. Response times are generally good but not instant, which can be frustrating if you need immediate help upon landing.

For travelers on a tight budget, Jetpac offers some of the lowest entry prices on the market. It is a great option for essential connectivity without breaking the bank, with prices starting at just $1.00.

Coverage

Jetpac offers global reach including key Asian markets. However, at its lower price point, network priority can sometimes be lower, leading to throttled speeds during peak hours in busy areas.

Usage

The service includes unique travel perks like lounge access on select plans, which is a nice bonus for a backpacker. However, the data plans are often limited in speed or duration compared to mid-tier offerings.

Customer Support

Assistance is primarily via email. While helpful, it lacks the real-time interaction needed for urgent connectivity problems.

aloSIM

Simple Setup

Rating
4.4/5
Coverage
Global
Support
Chat

aloSIM provides a straightforward eSIM experience. It is a reliable option for those who want a simple setup process. While primarily data only, it offers integration with Hushed for a temporary phone number.

Coverage

Coverage is standard for the industry, working well in urban centers like Taipei or Bangkok. Rural coverage may not be as robust as our top recommendation, which could be a factor for adventurous travelers.

Usage

Simplicity is key here, with an easy install process. The integration with Hushed allows for a phone number, but this requires a separate app and account, making it less integrated than eSIM4’s solution.

Customer Support

Support is available via chat, but users have reported variable response times depending on the time of day.

Pricing Plans

Feature Details
Starting Price $4.50
Network Various Partners
Extra Phone number via Hushed

Pros & Cons

Pros

  • Easy activation
  • Option for phone number
  • Good app design

Cons

  • Pricing is average
  • Customer support response times vary

How To Make Phone Calls with Your eSIM

Most travel eSIMs like eSIM4 provide data-only plans. Here are your options for making calls to stay connected:

Internet-Based Apps

You can use apps like WhatsApp, FaceTime, or Skype over your eSIM data connection. These work well for calling other app users, though you won’t be able to reach local businesses, landlines, or people who don’t have the same app installed.

Voice-Enabled eSIMs

Some eSIMs offer voice calling with a dedicated phone number, though these are less common and typically cost more than data-only plans. You’ll need to manage dual SIM settings and will receive a foreign number that may be difficult to share with contacts.

Using Yabb with Your eSIM

Yabb (owned by eSIM4) is a calling app designed to work with your eSIM data plan. Simply download the app and you can:

  • Call any landline or mobile number in Asia or worldwide (200+ countries)
  • Reach local businesses, hotels, and restaurants for bookings
  • Pay as you go with transparent pricing and no contracts
  • Enjoy clear call quality over your existing data connection

Available on iPhone App Store and Google Play, Yabb integrates with your eSIM4 data to provide calling functionality without needing a voice-enabled eSIM or relying on the other party having specific apps installed.

How To Send Text Messages

Sending text messages internationally is easy with eSIM, and if you’re using eSIM4, you have the option to use Yabb for SMS messaging as well. Most esim providers offer data-only plans, but Yabb provides a dedicated SMS service that works perfectly with your travel eSIM setup.

Yabb SMS Messaging Service

Yabb allows you to send and receive text messages to 200+ countries, making it ideal for staying in touch with family while you’re using data from your eSIM in Asia. Here’s what you need to know:

Yabb SMS Features

Why Use an eSIM in Asia?

Using an eSIM in Asia offers unparalleled convenience. You can avoid the language barrier at local shops, skip the queues at the airport, and have your connection ready the moment you land.

It is also more secure than physical SIM cards, which can be lost or damaged. Plus, you can keep your home SIM active for receiving important OTPs while using the eSIM for affordable data.

Setting Up Your Asia eSIM

The transition to digital SIMs has streamlined connectivity for travelers, offering flexibility and eliminating the fear of lost physical cards. Getting started is a straightforward process that takes just a few minutes.

First, select a reputable provider like eSIM4 and purchase a plan that covers your specific Asian destinations or the entire region. Once the transaction is complete, you will typically receive a QR code via email or instructions to activate via an app.

Simply scan this code within your smartphone’s “Mobile Data” or “Cellular” settings to install the profile directly into your smartphone. If you encounter any difficulties during the process, customer support teams are available to guide you through the activation steps.

Essential Tips for Using eSIMs in Asia

To ensure a smooth experience while traveling across the continent, here are three critical factors to keep in mind regarding your eSIM usage.

Check Device Compatibility

Before buying a plan, verify that your smartphone is eSIM-capable and carrier-unlocked. Most modern devices, including iPhones from the XR onwards and recent Android flagship models, support this technology.

Conserve Mobile Data

Even with a generous data allowance or unlimited data plan, it is wise to manage your usage efficiently. Consider downloading offline maps (via Google Maps or similar apps) while on Wi-Fi before you head out. You can also disable “Background App Refresh” for non-essential apps to prevent them from draining your data without your knowledge.

Prioritize Wi-Fi for Heavy Tasks

While your eSIM keeps you connected on the go, reserve bandwidth-heavy activities for hotel or café Wi-Fi. Streaming high-definition video, backing up photos to the cloud, or downloading large files should be done over Wi-Fi to preserve your high-speed mobile data for navigation and communication.

How We Ranked These eSIM Providers

While many reviews rely on simple speed tests that only reflect a single moment in time, our approach is built on rigorous industry analysis. Our team of telecommunications experts audits the technical specifications that average users might miss but definitely feel in real-world performance. We look under the hood to see how the connection is delivered, not just if it connects.

Our Technical Evaluation Criteria

  • Tier 1 vs. Tier 2 Network Access: We analyze the backend agreements to see if the eSIM connects to premium Tier 1 networks (like AIS, SoftBank, or SKT) with priority access, or if it is relegated to a congested Tier 2 roaming partner. This determines if your data slows down in crowded areas.
  • Latency & Routing Stats: Speed isn’t everything; responsiveness is key. We evaluate the data routing paths (latency) to ensure your traffic isn’t being routed halfway around the world before reaching the internet, which causes lag in video calls and maps.
  • Carrier Aggregation Support: We check if the eSIM profile supports carrier aggregation—a technology that allows your phone to connect to multiple frequency bands simultaneously. This technical feature, often missing in budget SIMs, is crucial for maintaining high speeds in dense urban environments.
  • Fair Usage Policy (FUP) Analysis: We scrutinize the fine print of “unlimited” plans to identify hidden throttling thresholds, ensuring our top picks offer genuine high-speed data that meets the demands of modern travel.
