Last night I factory reset my xperia xa just to have a fresh start and clear storage and then my problem occurred.
1) Got a notification that I need to login to my network.
2) Tried downloading Internet and mms settings but this failed even though the device was showing H+ or 4g.
3) I reset all network settings and then retried downloading Internet and mms settings. This worked and I was able to use 3g for a while before the problem occurred again.
4) I retried step 3 and this worked again but then the problem occurred a third time this method did not work until about the 8th attempt of resetting and redownloading. On this last attempt that was successful I had arrived in a location with good data signal, the previous attempts had been showing H+ or 4g but were in the mountains in Wales where the data connection is typically slow regardless of what connection is shown.
Other notes: During this process I have turned my phone off and on at each occurrence of the problem. Also my text and call service has been unaffected and has been working as usual throughout this. I have about 3GB of data to use. The device is properly updated.
I would like to know if there is a way to prevent this from happening again, perhaps a setting I need to change. I saw some other threads on a similar issue but nothing that seemed to be of use. I am commuting a lot and am relying heavily on my data connection. This would seem to be a device issue rather than a network issue and my network provider instructed me to contact the device manufacturer anyway.
Many thanks x
