Frequently Asked Questions
When you purchase an eSIM from Onesim you will instantly receive the eSIM QR code and all the relevant instructions to download and use it. If you didn’t receive your eSIM plan within 10 minutes, please check your spam folder first then contact us via [email protected]
The eSIM plan will start as soon as you scan and activate the QR code. Therefore, you can either buy the eSIM plan prior to your trip or after you arrive at your destination.
You can’t use an eSIM with a locked phone. To check whether your device is locked, please contact your carrier or check the [Settings] menu. If your phone is locked, you should contact your domestic carrier to unlock your phone before you can use the eSIM plan.
Onesim doesn’t offer top-up service right now. If you want to use your eSIM plan longer, you will need to buy a new eSIM plan.
Once an eSIM plan is installed, it can’t be reinstalled or reissued. If you are facing any problem, please don’t delete your eSIM plan - instead, contact Onesim team via [email protected] first.
