SIM card in Mui Ne: where to buy, what you need to register, eSIM
In Mui Ne a foreigner registers a SIM with a passport at a Viettel, VinaPhone or MobiFone store. What you need, how eSIM works and what to do if your SIM is blocked.
A foreigner gets a SIM card in Mui Ne with a passport at a Viettel, VinaPhone or MobiFone store, and an eSIM can be set up before you travel. The key is that the SIM is registered to your passport and you pass the face check in person: since April 2026 a number without that check can be cut off.

Where do you buy a SIM in Mui Ne and Phan Thiet?
The directory already lists three operator stores. In Mui Ne itself there is VNPT VinaPhone at 02 Nguyễn Minh Châu. In Phan Thiet there is MobiFone (Binh Thuan branch) at 01 Nguyễn Văn Cừ and Viettel in the Viettel Bình Thuận building in Phú Thủy. Hours and exact addresses are in the mobile and SIM cards section; call ahead or check the hours on the operator's map before you go.
What documents does a foreigner need?
Your original passport with a valid visa or visa-free entry. A foreigner's SIM is registered to the passport only. Four details are checked: document number, full name, date of birth and a face image. The rule is set by Circular 08/2026/TT-BKHCN of the Ministry of Science and Technology, in force since 15 April 2026, and by Decree 163/2024. In practice that means a visit to a store or signing up through the operator's app.
Can you get a SIM before you arrive in Mui Ne?
Yes, you can order a Viettel tourist SIM in advance at tourist.viettel.vn: it asks for a photo of your passport's photo page and a portrait photo, plus an email address. Operator counters exist at arrival airports, but we have not confirmed their exact location from the operators' or airports' official pages. Don't count on a specific counter: check with the operator or at the airport.
What tourist packages are there?
MobiFone has the Hi Vietnam app for visitors, where the eSIM packages are named HVN0 (a starter for one day), HVN3 (3 days), HVN7 (7 days), HVN15 (15 days) and HVN30 (30 days). With Viettel at tourist.viettel.vn you choose the tariff at the "Plan" step. Check the data allowance and current terms on the operator's site on the day you buy.
Are there eSIMs for foreigners?
Yes. MobiFone issues an eSIM in its Hi Vietnam app: you need a passport photo, a video call for identity checking and an e-signature. After installing the eSIM you call 900 to activate it. Your phone must support eSIM and be carrier-unlocked. Paid packages in the app need an international Visa or Mastercard. To avoid landing without data, set up the eSIM at home and activate it following the in-app instructions.
What if your SIM gets blocked?
If a number fails verification, under Circular 08/2026/TT-BKHCN the operator first blocks outgoing calls and SMS, then incoming service too, and can terminate the contract 5 days after that. After a phone change, outgoing service can be blocked within two hours, and you have 30 days to redo the face check. If that happens, take your passport and SIM to your operator's store. Ask the operator for the exact recovery steps: the circular does not describe them.
Is Mui Ne now part of Lam Dong?
Yes. Under National Assembly Resolution 202/2025/QH15 of 12 June 2025, Binh Thuan province was merged with Dak Nong and Lam Dong into a new province called Lam Dong, and the new authorities have operated since 1 July 2025. For you it means one thing: on maps and in addresses Mui Ne and Phan Thiet now belong to Lam Dong, and the old name "Binh Thuan" may still show up. It changes nothing about money or travel. For exchange, cards and ATMs see banks, and for getting to and from Mui Ne see transfers.
What do I do when my tourist package runs out?
In the MobiFone Hi Vietnam app there is no separate balance top-up: after the free 24-hour starter package HVN0 you buy a paid package for 3, 7, 15 or 30 days inside the app. You pay with an international Visa or Mastercard. Viettel's tourist page says nothing about extending a plan, so call its hotline 1800 8198.
