Frequently Asked Questions
After ordering, when do I get my eSIM?
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]
When does the eSIM plan start?
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.
How do I check if my phone is unlocked?
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.
How do I make a voice call?
Onesim provides data-only eSIM plans. Therefore local or international voice calls and SMS are not included in our eSIM plan. If needed, you are able to make a call via WhatsApp, Skype, or other social media through the use of your eSIM plan.
After my eSIM plan expires, can I extend it?
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.
Can I delete and reinstall my 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.

Excellent product. Worked right away when the plane landed. Will never go back to using a physical sim when travelling.
Viktoriya Belfer
Super easy to buy and set it up. Just scanned the QR code for the eSIM and my phone was connected to the network. Great option for travelers to get connectivity at a reasonable price.
