Yes. WhatsApp uses an internet connection, so a travel eSIM can provide the mobile data WhatsApp needs even when the eSIM does not include a new phone number.
Your WhatsApp account normally stays on the same number
WhatsApp is registered to the phone number you verified when you set up the account. Switching the phone's mobile-data connection to a travel eSIM does not automatically change that WhatsApp number.
A data-only eSIM is enough for WhatsApp data
Messages, voice notes, voice calls and video calls use internet data. If the travel eSIM has working mobile data, WhatsApp can use that connection. Data consumption increases substantially with long voice or video calls and media downloads.
Keep access to verification when needed
Avoid changing or reinstalling WhatsApp immediately before travel if you may need an SMS verification code and cannot receive messages on your primary number. Keeping the primary SIM active for SMS can be useful where your phone and carrier support it.
Control media downloads
If you are on a smaller data plan, change WhatsApp media auto-download settings so large photos and videos do not consume the allowance unexpectedly.
