Hi,
Your issue seems to be quite unusual. Maybe just the call number of the SMS Service Center is missing at you for an unknown reason but it shouldn't be related to the installed update. So, please try to process the followings:
1. Open the Messaging app, tap the 3-dot menu button at the top right corner and choose Settings
2. Tap on SMS Service Center and check whether the correct SMS service center number is there.
3. If it's missing or incorrect, enter the correct number (you can get it from your service provider), then tap on OK.
Now you may quit the SMS settings and try again to send and receive SMS.
Regards,
Ben |
