I. Which network should you choose in Hanoi?

Before buying anywhere to buy a SIM card in Hanoi, decide on the network first – the counter staff will ask.

  • Viettel: the best choice for most tourists. Viettel offers the strongest 4G/5G coverage in Hanoi city and the widest coverage if you are traveling beyond Hanoi to Sapa, Ha Giang, Ha Long Bay, or rural areas. According to speedtest, data speeds in Hanoi’s urban core reach 88+ Mbps in 5G zones.
  • Vinaphone: the solid second network carrier. Vinaphones’s coverage in Hanoi is comparable to Viettel. The key advantage is some plans include a Vietnamese phone number, useful if you need to register for Grab or receive OTP codes from Vietnamese services.
  • MobiFone: the budget option. MobiFone works well in central Hanoi but weakens in northern mountainous areas. Not recommended if your itinerary goes beyond the city.

II. Buying a SIM card at official stores in Hanoi

Official carrier stores in Hanoi offer the cheapest prices and the widest range of plans.

Moreover, staffs are patient and used to helping tourists – most speaking basic English.

What to bring:

  • Passport (required for registration)
  • Cash (VND preferred; some stores accept cards)

Buying process:

  • Choose the plan that fits your needs
  • Show passport
  • Staff registers and activates the SIM

Everything will be done in 5-10 minutes.

  • Top up your physical SIM: Buy a top-up card at any carrier store or convenience store. Dial 100[card code]# to add credit.
