For a few months I have noticed that I receive a failed to send message for some messages I send. This generally only happens at home even sending texts to my son in the same house. The strange thing is tho, that I have discovered that most, if not all the messages are successfully delivered. So why do I receive these failure reports? Any assistance gratefully received.
Try removing your SIM card and giving it a wipe with a dry cloth. If the issue persists, call into your local O2 shop for a free SIM swap.
