Once you've ordered your Xin Chao eSIM, it will only activate when your cellphone actually connects to a supported network in Vietnam. This means the validity period will only begin when you actually land in Vietnam and turn your cellphone on.

Your Xin Chao eSIM works with the dual-SIM function on most modern smartphones. This means you can use your regular SIM card alongside the Xin Chao eSIM (e.g. to receive incoming phone calls and text messages on your normal phone number).

Alternatives to Xin Chao

The main disadvantage of Xin Chao is the fact you're getting a data-only service on the eSIM. You will not get a local phone number in Vietnam when you're using the Xin Chao eSIM in your phone.

If you'd like to call or text whilst you're travelling in Vietnam, you'll need to use your normal SIM card instead (on which international roaming fees may apply). Alternatively, you can side-step these charges by making your calls through WhatsApp or other similar apps.

If you're looking for a more fully featured SIM card with a local phone number in Vietnam (starting with +84), you could consider getting a regular prepaid SIM card upon arrival instead. This will involve some additional hassle (e.g. queuing up at the airport to get your SIM card, a registration process for the SIM card, etc) but it can be preferable and better suited for longer-term use in Vietnam.

Xin Chao Coverage

If you're using a Xin Chao eSIM, you'll have access to 4G mobile coverage in Vietnam. This is provided by the following partner networks:

Coverage ProviderNetwork TypeCoverage Area

There's no international roaming available on a Xin Chao eSIM. Therefore, you won't be able to use it outside of Vietnam. If you're planning to visit multiple countries on your trip, you may need to get a separate eSIM for the other countries you visit.

  • Hi Ken
    Love this site!
    I’m off to South Africa in Feb 24 and I have a EE contract, they however do not cover that Country in their Data Roaming, what is the best way I can use my phone over there please?
    Get a sim when I land or do you know any other deals

  • I just arrived in the USA and Airalo is amazing – I bought the the sim on the airport wifi, and had it fully set up and on the network before I got to LAX baggage claim! So easy, no paperwork, didn’t need to find a shop/kiosk, queue, open up the phone or any of that nonsense. Also with dual sim capability I’m still able to use my British number for receiving sms/iMessage.

    It’s good coverage too, and it automatically swaps between AT&T or T-Mobile depending on the area. I’d highly recommend it and look forward to using it in other places in the future.
