Hi @Jammer3, let me see if i can be of any help here.

For how long have you been experiencing this and for how long have you been using your SIM card?

Are you able to search for a 4G network in the phone settings? In order to manually search for available mobile networks in the device, please follow the steps below.

1. Find and tap Settings > More > Mobile networks > Network operators or Service providers.
2. Select an available LTE network in the list that appears.

It is great that you have been able to test the SIM card in other phones, could you also try another SIM card in your phone in oder to see if the same thing occurs?

Try these measures and let me know how it goes!
