Q: Will installing an eSIM delete my physical SIM?

A: No. eSIM and physical SIM work independently. You can use both simultaneously in dual SIM mode.

Q: Do I need to remove my physical SIM to use eSIM?

A: No. You can keep your physical SIM in place and use both (dual SIM dual standby).

Q: Can I reinstall an eSIM if I delete it?

A: Usually no. Most eSIM QR codes are single-use. Contact your provider for a new QR code if needed.

Q: Why do I need to enable data roaming?

A: International eSIMs require data roaming to be ON because you're technically "roaming" on foreign networks, even though you won't be charged roaming fees.

A: Very little - typically less than 1MB. The QR code download and activation use minimal data.

Q: Can I use eSIM and physical SIM from different countries?
