What You Get and What You Don't

When you buy from Alt eSIM, you get a travel eSIM that roams on Metfone's network in Cambodia and Indochina. This means you can use your device seamlessly in these regions without needing a local SIM card. However, you do not get Metfone's own SIM or any contract with them. Our eSIM is a separate product that uses their network. For instance, if you're traveling to Cambodia for a week, you can easily activate our eSIM and stay connected. The caveat is that while we offer a convenient roaming solution, we are not affiliated with Metfone and cannot provide support for their services.

Applicable Destinations

Our eSIM roams on Metfone's network in Cambodia and Indochina, which includes Thailand, Vietnam, and Laos. This means if you're traveling to any of these countries, you can use our eSIM for your connectivity needs. For example, if you're on a trip that takes you through Vietnam and Laos, you can rely on our eSIM for consistent coverage. The caveat is that our eSIM will only work in these specific countries and not outside of them. So, if you're planning to visit other countries, you'll need to consider additional connectivity options.

Choosing the Right Plan Shape

When selecting a plan, you have two options: daily plans and total data plans. Daily plans are ideal if you want flexibility and are traveling for a short period. For example, a daily plan with 1GB costs US$1.06 per day. On the other hand, total data plans are better for longer trips where you need a fixed amount of data. For instance, a 5GB plan might be suitable for a two-week trip. The caveat is that once you choose a plan, you cannot change it, so it's important to estimate your data needs accurately.

Getting Connected

To get connected, you need to install the eSIM on your device. This process is straightforward and can be done through a QR code or by entering a code manually. Once installed, you can activate the eSIM and select it as your data provider. For example, if you're in Cambodia, you can activate the eSIM and start using data immediately. The caveat is that not all devices support eSIM, so you need to check if your device is compatible before purchasing.

What Happens When the Allowance Runs Out

Once your data allowance is used up, your connection speed will drop to 128 kbps. This speed is still usable for basic tasks like browsing and messaging, but it may be too slow for streaming or downloading large files. For example, if you're in Vietnam and your 3GB daily allowance is used up, you can continue to use data at a reduced speed. The caveat is that you cannot purchase additional data top-ups, so it's important to manage your data usage carefully.
