🇻🇳 Vietnam eSIM

Yes. aloSIM works in Vietnam on established local network infrastructure, and most phones bought after 2020 already support eSIM if they are carrier-unlocked. Vietnam is well set up for eSIM use across its major cities and tourist regions, so aloSIM is a practical way to get data on arrival without buying a SIM at the airport. Check your device on the compatibility page before you buy.

The best Vietnam eSIM depends on your data needs, but aloSIM is a strong choice because it combines low prices, 90-second setup, and a free Hushed phone number that many competitors leave out. Plans are priced for travelers, and every plan includes that number for calls, texts and app verification while you travel.

Buy your Vietnam plan in the aloSIM app before departure, open ‘My eSIMs’, and tap ‘Install eSIM’ — installation takes about 90 seconds. Toggle the eSIM on and allow roaming when you land, and data starts automatically. This is faster and cheaper than hunting for a physical SIM at the airport when you arrive.

Yes. aloSIM works with dual-SIM phones, so you can keep your regular SIM for calls and texts while using your Vietnam eSIM for mobile data. This gives you local connectivity in Vietnam without giving up your usual number — just check your home provider’s roaming charges before you travel. Most travelers keep the home SIM on for calls and route their data through aloSIM to keep costs down.

Your aloSIM Vietnam eSIM runs on MobiFone, covering populated areas including the major cities and tourist destinations. Coverage can be weaker in more remote and rural areas, as with any mobile network. Download Google Maps offline before heading off-grid so you can still navigate, and reconnect automatically once you return to coverage.

For most travelers, aloSIM is better than pocket WiFi in Vietnam because you do not need to carry, charge, pick up or return another device. Pocket WiFi still makes sense for groups of three or more sharing one connection, but an eSIM is easier and often cheaper for solo travelers and couples.

No, but aloSIM gives you a useful alternative. Every Vietnam eSIM includes a free Hushed phone number for hotel check-in texts, WhatsApp and local app sign-ups, so you have a reliable number the moment you arrive. That is more flexibility than a standard data-only eSIM from many competitors, which leave the number feature out entirely or charge extra for it.
