Vietnam
Local SIM cards in Vietnam can be cheap, but they take more effort. You often need to show your passport, pick the right physical SIM size and sometimes deal with a language barrier.
With an eSIM, all of that disappears. You can buy, install and activate it from your phone in a few taps. You also avoid handling tiny SIM cards and risking roaming fees on your usual SIM. This is especially useful if your phone supports dual SIM, because you can keep your original number while using your Vietnamese eSIM for data.
For travelers, yes. eSIMs are more flexible, safer and easier to manage. You can switch providers or top up your plan without visiting a store. More importantly, a growing number of smartphones now support eSIM. That is why the best eSIM for Vietnam is often the simplest way to stay connected abroad.

Most eSIMs are data only, which means you will not get a local number. However, you can make calls through WhatsApp, FaceTime, Skype or similar apps using your mobile data.
Some providers offer extra options for calls and texts, but they are rare and not always necessary. If voice calls matter to you, consider VoIP apps or a local SIM card.
Usually not. eSIMs such as Airalo or Holafly offer data only, which suits most tourists. If you need a Vietnamese number for verification, use a local prepaid SIM card.
Viettel offers the best 4G coverage and a fast-growing 5G network. Depending on the plan, eSIM providers rely on Viettel, Vinaphone (VNPT) or MobiFone. Vinaphone and MobiFone also offer competitive speeds in urban areas.
Airalo and Holafly rely on Vinaphone (VNPT), while Nomad uses Vinaphone, MobiFone or Vietnamobile. These networks offer good speed and reliability for everyday use, including streaming, video calls and browsing.
You can buy SIM cards at the airport or in local shops from Viettel, Vinaphone or MobiFone. They are cheap, but less convenient than eSIMs.
Some companies sell physical SIM cards that you can buy before you leave. They are bulkier and more expensive than eSIMs.
