3. RedteaGO eSIM is not available on locked iPhones. (When you buy a device with a contract from a mobile operator, it is common practice for them to lock the connectivity from any other supplier. In this case your device will be considered 'locked'—at least until your contract expires. You can check with your operator to see if there is anything you can do to unlock the eSIM in your device.)
Here are a few of the many ways you can use eSIM as Dual SIM
when you have the need:
- To use one number for business and another number for personal calls.
- To add a local data plan when you travel outside of the country or region.

Dual SIM is a combination of a physical nano-SIM and an eSIM, a digital SIM that allows you to activate a data plan without physical nano-SIM.

from the device and manufacturer.

Are you in an area with network coverage?
In an area with limited mobile coverage, or no coverage at all, you will find it difficult to access the internet. Try switching locations until you get enough signal bars to connect to 3G or 4G/LTE.
If you are in good coverage and tried everything else, always try a restart and see if that helps.
We feel sorry to hear that, and suggest not to delete the eSIM until the data plan is finished. If you delete a valid eSIM order, the data plan can't be used any more.
Unfortunately, it is not possible with the current eSIM architecture. We suggest you get a new eSIM.
