Just keep in mind that current values are really misleading, and your tests confirmed it - stating CSQ 17 as 100% signal is laughable, to say at least (of course it's not your fault, bullet at Nokia[?]).
Remarks/questions:My operator does not supply network time AFAIK, so can anyone who does receive this, check if a (valid) time is displayed using "Provider info"?
My primary device has 112/911/999 as emergency numbers, while my backup device shows 112/911/118/119/000/110/999/08. Can't relate it to regional or device settings. Any clue why they differ? Only difference is that my backup device has no SIM card, perhaps that's the cause.
opencellid.org is giving me issues retrieving cellinfo (failed to lookup cellid). Most likely opencellid.org related. This version should deal with that without errors, and you can always disable the internet lookup. So far, I have not heard they have changed their API.
