Question 1

Can I use the eSIM to register a WhatsApp number?

Accepted Answer

No, our eSIMs are data-only and do not include a phone number, so they cannot be used for WhatsApp verification. If you need to register a WhatsApp account, we recommend using a local SIM card that provides a phone number.

Question 6

When does the eSIM validity start?

Accepted Answer

The validity starts once the eSIM is installed and connected to the local network at your destination eSIM.

Don’t worry — your data plan will not be deducted until the eSIM connects to the destination network.
