How does our Vietnam eSIM work?

An eSIM is an embedded SIM card, and you probably already have an eSIM-compatible device. When you install an eSIM for a country or region, it lets your device connect to local networks in that area. This means your device will have data without needing Wi-Fi or paying roaming charges.

Vietnam is a beautiful Southeast Asian country famous for sandy beaches, flowing rivers, and cities bursting with life and color.

While in Vietnam, you’ll want to share your travel experiences with your family and friends back home. A Vietnam eSIM can keep you connected with steady mobile data, so you don’t have to worry about finding Wi-Fi.

Your Vietnam eSIM will connect your phone or tablet to local networks anywhere you travel, so you always have data for what matters.

Will I pay roaming charges with a prepaid eSIM for Vietnam?

You won’t pay any roaming charges with a Vietnam eSIM from aloSIM because everything is prepaid.

You’ll be paying upfront to be connected to local networks in Vietnam, and then you’re free to use your data package as quickly or slowly as you’d like.

Just make sure to turn off Data Roaming for your primary SIM, to avoid carrier roaming charges back home. (We’ll show you exactly how to do this.)

FAQs about using a Vietnam eSIM

Check my device

Most newer phones, tablets, and computers are already eSIM-compatible, so use our eSIM device checker to make sure you have a device that can accept an eSIM.

Free Wi-Fi is great when it’s available, safe, and working well, but some destinations make it just about impossible to get a good connection. That’s why it’s nice to have data as a backup to stay connected.

We’re proud to provide aloSIM customers with fast eSIM data connections that allow them to talk, text, surf, and stream comfortably. You’ll likely experience a 4G (sometimes 5G) or LTE equivalent network in most locations, depending on what’s available in the area.

Installation guides

We have detailed eSIM installation instructions for all compatible devices, so whether you’re looking to add eSIM data to an iPhone or iPad, Google Pixel, Samsung Galaxy, or something else, we’ll be able to walk you through the eSIM set-up process easily.

How to avoid roaming charges

It can be confusing to know the best roaming settings for your phone while you travel internationally, so we’ve created an easy walk-through guide to show you exactly how your phone’s roaming settings should look.
