Vietnam eSIM — FAQ
How do I get an eSIM for Vietnam?

Will my phone work with a Vietnam eSIM?
Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3+, and recent Samsung Galaxy S/Z models. Your phone must be carrier-unlocked.
Does the Vietnam eSIM include 5G?
Yes — our Vietnam plans connect to 5G where the local network supports it, and fall back to 4G/LTE automatically.
Which network will I connect to in Vietnam?
Our Vietnam plans use partner networks including DTAC Indonesia:Telkomsel, Digi, MOBIFONE and MOBIFONE CORPORATION. Available networks depend on the selected plan, device and location.
Is there a plan that covers Vietnam and other countries?
Yes. Asia, Global Lite, Global Max and Global are regional plans that include Vietnam, which is usually cheaper than buying each country separately on a multi-stop trip.
Can I keep my own phone number?
Yes. The eSIM runs as a separate data line, so you keep your main number for calls and texts while using Vietnam data on the eSIM.
When does my plan start?
Activation rules vary by plan. Check the activation note at checkout before installing your Vietnam eSIM; some plans start on connection or first data use, while others have different activation rules.
