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

Alternatives to Cu Chi

The main disadvantage of Cu Chi 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 Cu Chi 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.

Cu Chi Coverage

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

Coverage ProviderNetwork TypeCoverage Area
Mobifone4G LTEVietnam
Viettel4G LTEVietnam

There's no international roaming available on a Cu Chi 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.
