Which Vietnam eSIM Has a Phone Number? Only Vinaphone

Only Vinaphone eSIMs include a real Vietnamese phone number that can receive incoming calls and SMS. If your travel plans require a local number for ride‑hailing verification, hotel check‑in, or banking OTPs, Vinaphone is the only choice among the eSIMs we offer.

Viettel and Skyfi (Mobifone) eSIMs are data‑only — they provide no phone number, no SMS, and no voice capability. Both are excellent for pure data usage, but if you need a number, they cannot provide it.

For example, Grab often sends a one‑time password via SMS when you first register, and some hotel bookings ask for a local contact number. In those cases, a data‑only eSIM leaves you stuck. Vinaphone solves that.

Grab and other ride‑hailing apps are the most common reason. While the app itself works over data, the initial registration and some driver‑contact features rely on SMS. Without a local number, you may need to ask a hotel staff or friend to receive the OTP for you.

Some hotel and tour bookings ask for a Vietnamese phone number during check‑in or for confirmation calls. If a driver or guide needs to reach you, a local number that receives calls is far more reliable than relying on an international roaming line.

Vietnamese bank transactions — even mobile payment apps like Momo — often send OTPs via SMS to a local number. If you plan to use a local bank card or transfer money, a Vinaphone number is useful.

With a Vinaphone eSIM, you also have the option to make outgoing calls if you top up prepaid credit separately (this is not included in the plan). Without a local number, you rely entirely on data‑based apps like WhatsApp or Telegram — which many local businesses do not use for phone calls.

Our Vinaphone eSIM plans — 5GB/day for 10, 15, or 30 days — all include a real Vietnamese phone number. The number is assigned when you activate the eSIM and remains valid for the plan duration. You can receive incoming calls and SMS normally.

Outgoing calls are not part of the plan. If you need to call out, you must top up the Vinaphone carrier account with prepaid credit (a separate service we do not sell or advertise). The number can still dial emergency numbers without credit.

Pricing: 10 days $11.9, 15 days $13.9, 30 days $18.9. Coverage is good in cities and major tourist areas; in remote rural areas, Viettel generally has better signal. But for most travelers, Vinaphone's network is perfectly adequate for city travel and popular destinations.

Our Viettel eSIMs (5GB/day, 7/15/30 days) are data‑only — no phone number, no SMS, no calls. Viettel's strength is speed and coverage. It has the widest 4G/5G network in Vietnam, including many rural and mountainous areas where other carriers may be weaker.

Skyfi (Mobifone) eSIMs — 7GB/day for 7, 10, or 15 days — are also data‑only. They offer a higher daily data cap at a lower price per day than Viettel or Vinaphone. If you only need data for maps, social media, or video calls, Skyfi is a solid choice.

Both Viettel and Skyfi work fine with WhatsApp, Telegram, FaceTime, and other VoIP apps for voice and messaging. But you will not be able to receive SMS from Vietnamese services or receive phone calls. If you already use a second number (e.g., Google Voice) for verification, these plans are sufficient.

Choose Vinaphone if you need a local Vietnamese number for Grab, banking OTPs, or simply for peace of mind that you can be contacted by phone. It's the only eSIM we sell that includes a real number for receiving calls and SMS.

Choose Viettel if your priority is the fastest and most reliable data connection, especially if you plan to travel outside cities or into remote areas. Viettel's network is widely considered the best for coverage.

Choose Skyfi (Mobifone) if you want the highest data cap per day at the lowest price and do not need a phone number at all. The 7GB/day plans are great for heavy data users who rely on VoIP for communication.
