I've had a Nokia 5 for some time now and it has been running Oreo 8.1 just fine as well. Starting to have a few issues sending text messages to isolated users.
Comes back with an error 38. Essentially once this happens I cannot reply to messages or initiate messages to select individuals. (currently 3 people in my contacts list).
Had a suggestion it might be a flakey SIM card. Looking for confirmation or insite or some trouble shooting steps please.
Thanks
