Vietnam SIM card for non-eSIM phones – physical SIM guide

eSIM is the most convenient solution for most travelers, but not every phone supports it. If you have a mainland China, Hong Kong, or Macau iPhone, or an older device without eSIM hardware, you will need a physical SIM card to get online in Vietnam. At simvietnam.telebox.vn we recommend checking your phone's compatibility before departure and, if needed, picking up a physical SIM upon arrival.
Which phones cannot use eSIM in Vietnam?
Mainland China iPhones – all models from iPhone XS onward – lack eSIM hardware entirely. The same applies to iPhones sold in Hong Kong and Macau according to our policy. If you own one of these, you cannot activate an eSIM in Vietnam and must use a physical SIM instead. This surprises many travelers, so check before you fly.
Older Android phones also miss eSIM support. Samsung Galaxy S20 series and earlier (released before 2020) do not include eSIM. Google Pixel 2 and earlier, as well as LG V40 and earlier, likewise lack the feature. Many Xiaomi, Huawei, and Oppo models sold in China have eSIM disabled in firmware. Basic smartphones and feature phones almost never support eSIM. If your device is on this list, a physical SIM is the only way to access mobile data in Vietnam.
Buying a physical SIM at the airport
Viettel, Vinaphone, and Mobifone maintain official counters at Vietnam's major international airports: Noi Bai (Hanoi), Tan Son Nhat (Ho Chi Minh City), and Da Nang. These counters are easy to find in the arrivals hall. The typical price for a 7-day prepaid SIM is between $5 and $10 – a common range known from publicly available information.
You must present your passport to purchase any SIM; this is required by Vietnamese telecom regulations. Staff will install the SIM in your phone, activate it, and test data connectivity before you leave. Data packages usually include 3–5 GB per day, sometimes with unlimited data at reduced speed after a daily threshold is reached. This is convenient for immediate use after a long flight.
Buying a physical SIM in cities or convenience stores
If you prefer to buy after arriving in the city, Viettel and Vinaphone stores in downtown areas sell the same SIMs at slightly lower prices – roughly $3–$6 for a 7-day plan. Convenience stores such as Circle K and Family Mart also carry starter kits with pre-loaded data. Prices vary by location but are generally cheaper than the airport.
A passport is still required for purchase. Registration is usually done online by the store staff, so the process is quick. For top-ups, you can buy scratch cards at convenience stores or add credit directly at carrier counters. This is handy if your data runs out during your stay.
Activation and important setup tips
Installing a physical SIM is straightforward: insert the SIM into your phone and check for signal. The Access Point Name (APN) is typically set automatically by the carrier. If mobile data does not work, manually enter the correct APN: for Viettel use 'viettel.vn', for Vinaphone use 'm-wap.vn'. This fixes most connectivity issues.
If you use a dual-SIM phone, set the Vietnamese SIM as the default for mobile data while keeping your home SIM active for calls and SMS. On an iPhone, go to Settings > Cellular > Cellular Data and select the Vietnamese line. On Android, navigate to Settings > Connections > SIM card manager and choose the default data SIM. This ensures you use the local data without accidentally roaming on your home carrier.
FAQ
Can I use a physical SIM and an eSIM together if my phone supports eSIM?
Yes, if your phone supports both eSIM and physical SIM (dual SIM support), you can use a local physical SIM for data and keep your home eSIM active for calls and SMS. This is a common setup for travelers who want to avoid roaming charges while staying reachable on their home number.
Where is the best place to buy a physical SIM at Hanoi airport?
At Noi Bai International Airport in Hanoi, Viettel and Vinaphone have official counters in the arrivals hall. Both offer competitive prices and instant activation. We recommend comparing their data packages before purchasing. The counters are clearly marked and staff speak basic English.
Do I need to show my passport to buy a physical SIM in Vietnam?
Yes, Vietnamese law requires all telecom SIMs to be registered with the buyer's identity. You must present your passport when purchasing either at the airport, a carrier store, or a convenience store. The store will scan or copy your passport and complete registration on the spot.
What are the typical data prices for a 7-day physical SIM?
At the airport, expect to pay around $5–$10 for a 7-day prepaid SIM with 3–5 GB of high-speed data per day. In city carrier stores, prices are slightly lower, roughly $3–$6. Convenience store starter kits may be priced similarly. These are typical ranges based on publicly available information.
Can I top up a physical SIM in Vietnam?
Yes, physical SIMs from carriers like Viettel and Vinaphone can be topped up. You can buy scratch cards at convenience stores or carrier shops, or add credit directly at store counters. Note that some tourist-oriented SIMs have a fixed validity period; top-ups may only add data within that period. Always confirm with the seller.
