I'm heading to Vietnam soon and want to use a local eSIM for data. However, I wish to keep WhatsApp active with my home number. What's the best way to achieve this without any disruption?

To keep WhatsApp on your home number, simply set it up before you switch to your eSIM. The app will continue to use your home number as long as you don't re-register it with a new number.

I've done this in Vietnam. Install the eSIM for data, but keep your WhatsApp linked to your original SIM. Just don't remove the app or change its number settings.

Make sure you have your home SIM in a safe place, as WhatsApp verification needs it initially. Once set, your eSIM data will cover your connectivity needs.

I traveled to Vietnam last month and used an eSIM. Just activate the eSIM and use it for data while keeping the WhatsApp number linked to your original SIM. No issues at all!

Remember, WhatsApp doesn't need to verify the number again if you switch SIMs, unless you uninstall the app or try to change the number.

I've switched between eSIMs and SIMs multiple times. Keep the WhatsApp app updated, and there's no need for any number change unless you want to.

While in Vietnam, I used my local eSIM for data and had no problems with WhatsApp on my foreign number. It’s pretty seamless!

Just make sure to disable any automatic SMS backup for WhatsApp, which might require the old SIM temporarily. Otherwise, you're good with just data access.
