Apple Maps not working: is it GPS 3/4G "conflict"?
Until recently, I had no 3G/4G contract and exclusively used wifi for connecting to the internet and all that time Apple Maps worked just fine (save for its well documented birth pangs) even when away from any wifi access point which, I presume, was via the GPS functionality of my 64GB 3rd generation iPad.
Recently (and coincidentally almost simultaneously to the release of iOS7, which fact I believe to be a red herring unless you know differently) I acquired a mini-SIM for 3G access via Samba Mobile. This is for "emergencies" only for the very few occasions when I need access and there is no wifi available.
Now, though, when I have Cellular Data set to off (so that I don't connect via 3G and eat up my data plan unless specifically "authorised") Apple Maps doesn't work unless I am on wifi.
From which, in my usual default position of congenital ignorance, I infer that turing off Cellular Data in Settings stops Apple Maps (and probably other as yet unnoticed apps) accessing the internet.
So - and please speak in simple terms here, for I am not a technodweeb - is there any way I can retain the previous GPS functionality for Apple Maps without removing the SIM card each and every time?
Is there another setting which I have overlooked or have I burnt my boat as far as GPS is concerned by installing a 3G SIM card?
Thanks in advance.
