I'm traveling to Vietnam soon, but I want to keep my home WhatsApp number active so I can stay in touch with family and friends. Should I use the eSIM for data and keep my home SIM in the phone, or is there a better way to handle this? Any tips?

To keep your WhatsApp active on your home number while in Vietnam, you can use the eSIM for data while keeping your home SIM card in your phone. Just ensure you have an active internet connection to access WhatsApp.

I did this last year when I was in Vietnam! I just kept my home SIM in the phone and used the eSIM for data. WhatsApp worked perfectly for me.

Make sure to enable roaming on your home SIM if you want to receive messages without issues. I had my local eSIM for data but turned on the home SIM when I needed WhatsApp.

Another option is to set your WhatsApp to "Use on Wi-Fi only" mode. This way, you can keep your home number active and just use the eSIM for data access when needed.

When I traveled, I kept my original SIM active and just used the eSIM for browsing. It worked smoothly, and I didn’t miss any messages.

I recommend testing your WhatsApp right after arriving in Vietnam. Sometimes there's a slight delay in connecting, so don't worry if it doesn't work right away!

If you rely heavily on WhatsApp, consider notifying your contacts before leaving. That way, they'll know to reach out via your new number if there's a problem.

I also suggest downloading the latest version of WhatsApp before your trip. Having the latest updates can help avoid connectivity issues.
