Common Questions

Does my phone support eSIM?

On iPhone: Settings → General → About — look for an EID number. On Android: Settings → Network & Internet → SIMs → Add SIM. If the option exists, eSIM is supported.

Do I need to unlock my phone?

Yes, for third-party travel eSIM plans. Contact your home carrier to request an unlock. Most carriers unlock devices after the contract period ends.

Can I keep my home number?

Yes. With Dual SIM, keep your home physical SIM for calls while using the eSIM for data. You'll never miss calls or two-factor authentication messages.
