Many thanks again for your replies and I will keep the issues to this one thread instead.
First some notes from your post:
"You didn't try a SMS/call, or they didn't reach the bts."
I did, on multiple occasions whilst the debug was running.
"You won't receive any sms if that imsi was previosly registered, log will be kept for a few weeks and it will not try to send sms again even if you try to close the phone and register again. Send sms to eliza number from the phone you managed to register. "
All Messages to Eliza fail too. So I can connect to the network but I can not even text Eliza .
With regards to calling David, that does not work either. When I place a call and press call, there is no response tone at all.
So just to go over my issues
I can connect to my BTS network
But then I can't text Eliza nor can I call David.
Thank you for all your help so far, I am appreciative of your suggestions as I can't seem to find support anywhere else for the issues I am having.
