Troubleshooting a Hardware Connection Problem After Replacing Your Windshield
It appears that the issue you are having is related to a hardware connection problem with the antenna. This could be due to replacing your windshield, which may have damaged the 4G antenna that the car uses to connect. It is possible that both SIM cards in your car are eSIMs, and one of them has failed to make a connection.
To troubleshoot this issue, it is important to first confirm that the built-in SIM card is active and registered to your name. If this is confirmed, then it is likely that there is a hardware connection problem with the antenna. In this case, it would be advisable to contact the service company who replaced your windshield for further assistance. They should be able to diagnose and repair any damage done during the replacement process. Additionally, if necessary, they can also recalibrate sensors and cameras as part of the repair process.
It is also worth noting that GPS accuracy can be affected by hardware connection issues with the antenna. If you find that your GPS readings are off by 20-30km, it could be an indication of a hardware connection problem with the antenna.
In conclusion, if you experience any issues with registering on the network or connecting to remote services after replacing your windshield, it is important to check whether there is a hardware connection problem with the antenna. If so, contact the service company who replaced your windshield for further assistance. They should be able to diagnose and repair any damage done during the replacement process and help get your car back up and running again.
