eSIM technology is new, and not all devices are compatible.
To check if you can use eSIM on your phone, consult our updated list of compatible devices.
Also, make sure your phone is unlocked and free from restrictions imposed by your local carrier.
For example, the Samsung S20 and S21 FE models do not have eSIM enabled. Additionally, if your iPhone is from China, it’s important to confirm its eSIM compatibility with the manufacturer.
In any case, it’s best to verify compatibility before purchasing the eSIM.
