The Main ESIM Providers in Asia 2024!

Sep 28,2023 | Tom



Airalo is a popular eSIM provider addressing the needs of travelers heading to various destinations in Asia. Their service boasts affordable prices, robust network stability, widespread coverage, and high flexibility in terms of data packages.

In a review of the available information, let's list the pros and cons of Airalo, an eSIM provider:


  • Global Reach

Airalo offers eSIMs that you can use in more than 190 countries and regions worldwide which makes it an excellent choice for travelers.

  • Affordable Pricing

Since Airalo partners with local network providers, it allows lower costs for their eSIM packages, keeping them affordable for their users.

  • Convenient

Airalo eliminates the need for physical SIM card purchases, offering the convenience of staying connected just by using the Airalo app and setting up the plan based on the destination.

  • Diverse Local and Regional Data Plans

Airalo provides a wide range of local and regional data plans providing users the flexibility to choose based on their requirements.

  • Easy Setup

The process to set up Airalo on your phone is straightforward and quick, contributing to user convenience.


  • Limited Services

Most plans provided by Airalo are data-based. This means the ability to make standard phone calls or send standard SMS messages might not be available, limiting the service to data usage only. Besides, no unlimited data plans are available, you have to top up on the platform if the data plan runs out.

  • App-Reliant Communication

Because Airalo mostly offers data service, any kind of communication (phone call, text) has to be done through internet-based applications like Skype or iMessage, which might not be preferred by all users.

  • Device Compatibility

Note that not all phones are compatible with eSIMs, so the services of Airalo may not apply to all phones currently in the market.

Overall, Airalo appears to be a sound choice for the global mobile user population that is primarily focused on data usage. However, for those who depend on traditional call and text services, it might not be the ideal choice. It's always recommended to refer to device compatibility and network services based on the destination before investing in an eSIM package plan.



Another notable eSIM provider, Holafly, offers tailor-made eSIM plans for multiple Asian destinations, accommodating various travel needs. Holafly presents robust network connections and competitive pricing options along with flexibility in data packages, including unlimited options for certain destinations.

Here is a list of pros and cons for Holafly, based on the information derived from the internet:


  • Ease of Use

Holafly offers a simple and convenient setup process for their eSIMs, allowing users to easily add local data plans to their phones by scanning a QR code.

  • Wide Coverage

Holafly provides eSIMs for more than 130 countries, enabling travelers to stay connected to various destinations without the need for purchasing and switching physical SIM cards.

  • Reliability

Users report positive experiences with the data connection provided by Holafly eSIMs, even in remote areas such as the Sahara desert, indicating good network coverage and stability.

  • Hassle-Free Experience

With Holafly eSIMs, users can avoid the hassle of searching for local SIM cards upon arrival, dealing with language barriers, or facing issues with the availability of SIMs in certain locations.

  • Cost-Effective

Holafly offers competitive pricing for their eSIMs, making them a cost-effective option for international travelers seeking reliable data connectivity.


  • Limited Service

Similar to other eSIM providers, Holafly specializes in unlimited data plans, which means you cannot customize and pay for your data according to your practical needs(not friendly for light/middle data users ). Besides, services such as voice calls and regular text messaging may not be available through their eSIMs.

  • Device Compatibility

Holafly's eSIMs are dependent on the compatibility of users' devices. It is important to check whether your device supports eSIM technology before considering Holafly as an option.

  • Tethering/Hotspots

You can’t share your Holafly eSIM data installed on your handset with other mobile devices although it's an unlimited data plan. If you're planning on using a hotspot, it's worth checking out.

  • Network Stability

The network stability is not always as good as any country/region because of different local carriers and network facilities. Besides, you may suffer a speed limit if your data usage exceeds the regulated amount, which means you’ll get high speed first, and eventually, you’ll get a slower speed if you use too much data.

Overall, Holafly is praised for its user-friendly setup process, wide-coverage, reliability, and cost-effectiveness. However, it's important to note the limitations in terms of limited services (mainly data-focused) and device compatibility. Holafly can be a suitable choice for heavy-data users while traveling internationally.
