I recently activated my BYOP device. I don't recall being asked for the scratch-off Network Access Code PIN during the process, and I'm not sure if that's relevant to this issue.
I am in anreas of solid 4G coverage, but I'm getting sporadic 3G at best, often with no data connectivity. Calls to *22890 won't go through, but that may be barking up the wrong tree.
As far as I can tell, there are no no manual setting adjustments that I need to adjust on my phone. If there are settings that need to be tweaked, could someone send me a cheat-sheet, please? Many thanks.
