as a result of our tests, we came to the conclusion that there are some variants and all valid for all manufacurers, either Gevey, X-SIM or R-SIM.
- iPhone 4S - Can update on GSM Phones
- iPhone 5 - Can update on GSM Phones (2G Data)
- iPhone 5C and 5S - Not compatible!!! In this case we recommend our IMEI UNLOCK
As we're in Europe we cannot test CDMA phones (Sprint/Verizon).
In the case that you are using a 64Kb/128Kb SIM and have issues (NO SERVICE) just follow this procedure that will fix it:
- Install Rsim + Sim, choose carrier, and phone, reboot
- Download iRoseTool to your desktop
- Open iTools or iFunBox and drag and drop iRosetool.ipa onto iPhone
- Force 2G or Force 3G if you have 64k/128k SIM
- Use unlockit.co.nz to install carrier bundle (APN Settings)
