#### 23. USIM and UE settings
- Make sure to disable SQN check in Sysmocom SIM cards using sysmo-usim-tool tool [https://github.com/herlesupreeth/sysmo-usim-tool](https://github.com/herlesupreeth/sysmo-usim-tool)
- Tested with OnePlus 5 - With modfication to enable force IMS registration is a must or else UE will not even attempt to connect to P-CSCF. Need to apply the fix back after each update.

- Tested with OnePlus 5 with following methods (Official Google method is the recommended method to prevent damage to phone)
- (Official Google method) - Please follow the instructions in the following link [https://github.com/herlesupreeth/CoIMS_Wiki](https://github.com/herlesupreeth/CoIMS_Wiki) to force enable VoLTE using Carrier Privileges
- (Risky method) With modfication to enable force IMS registration is a must or else UE will not even attempt to connect to P-CSCF. Need to apply the fix back after each update.
