Why am I not receiving text messages on my eSIM?

Because almost all eSIMs for travel are data-only profiles: they provide internet, but they don't come with their own phone number. SMS still go to the physical SIM, with your usual number, not to the eSIM.

Can I have both eSIM and physical SIM active at the same time?

Yes. Most eSIM-compatible phones allow you to have both lines active at the same time: one for data (the travel eSIM) and one for calls and SMS (your usual physical SIM).

Do I need to remove my physical SIM to use an eSIM?

No. There's no need to remove or turn it off. You can leave it inserted and with signal to continue receiving calls and messages, while the eSIM handles only the data.

Do PuraSIM eSIMs include a phone number and SMS?

No: they are data eSIMs designed for browsing while traveling, not full lines with a number. For calls and SMS, you use your physical SIM or internet messaging channels.

How do I know if my phone is compatible with eSIM and dual line?

Check your phone's settings to see if there's an option to add an eSIM plan. Most recent models from major brands are usually compatible, but it's best to confirm before buying.

What do I do if my bank only verifies via SMS and I'm not receiving the code?

Check if the bank offers verification by call or email as an alternative, and confirm that your physical SIM has active voice/SMS roaming while you are at your destination.

Why was I receiving SMS on my phone before, but not since installing the eSIM?

Most likely, when setting up the eSIM, your phone changed which line it uses for calls and messages. Check your line settings and make sure the physical SIM is still marked for SMS and calls.

Does the eSIM affect my WhatsApp number?

No. WhatsApp works over data, so it continues to function with the eSIM without a problem, as long as your original number (the one you registered with WhatsApp) remains the same.
