Hi @kelly7800 , Download, install and run the following two apps. They are both free to use. You can uninstall them after they have removed any malware or viruses (if any) that they may have found. This one will test for and remove any malware that has been installed in your phone. This will test for and remove any viruses that may have been installed in the phone (or that might have been missed by the first app). Run one at a time obviously ;-) There are other apps available that do the same thing if you don’t want to use either. Just search for anti-malware or anti-virus apps for Android phones

Ensure the Sim card is inserted correctly, ensure you have valid credit on the Sim card. If that doesn’t work, the phone may be network locked, meaning only a certain Sim can operate in the device. If you still need help, try seeing one of that company’s helplines. Goodluck :)
