IMEI unlocking will enable your phone to be used on any network worldwide.
When IMEI unlocking is not possible, the alternative solution, UnlockMySIM Card will also unlock your phone to use it on any network.
In the case of apple, some models are restricted from using CDMA networks. These models include:
- A1778 y A1784 (iPhone 7 and 7 Plus).
- A1905 y A1897 (iPhone 8 and 8 Plus).
- A1901 (iPhone X).
If you unlock these phones (either via IMEI or UnlockMySIM) you won't be able to use them on CDMA networks such as Sprint or Verizon
