Can I use the UnlockMySIM card to switch to a carrier using CDMA technology such as Sprint, Verizon or US Cellular?

IMPORTANT! It is no longer possible to purchase the UnlockMySIM Card as it may not work at the current time due to an internal update beyond doctorSIM’s control.

  • Can I use my UnlockMySIM on a CDMA network?

Yes, except for some specific iPhone models.

If the SIM card you are going to use with the UMS belongs to a CDMA network (Sprint, Verizon, Boost Mobile, etc), the UMS is compatible as long your iPhone is not on the following list:

- A1778 and A1784 (iPhone 7 and 7 Plus).
- A1905 and A1897 (iPhone 8 and 8 Plus).
- A1901 (iPhone X).
