My signal was showing 4G 2-3 bars all day, and according to iD mobile’s coverage map Oxford is fine for 4G and even 5G. Yet I visited there last week with my wife (also on iD mobile) and neither of us could access anything via the internet (data calls, Google maps, internet browsing, YouTube etc). We had no problems calling each other with normal calls.
This is a pretty big red flag. Any reason why this may be the case and anything we can do about it?
