Very odd.  I joined iD today, popped in the new SIM on my BV9100, the phone is about 10 years old, and everything, so far, just works. 

I’m an ancient IT geek and would be interested in why a communications protocol would fail on an Android phone.  I am aware that BV do lock down the operating system, but am sure than many phone manufacturers do the same.  

Hi Sandy 

Thank you so much for your reply

I'm as far from an IT geek as you can be, but I am a very very heavy mobile phone user and have had rugged phones with ID for years now. By this I mean, I am very clumsy and my phones tend to have a hard life. I've just swopped from a  Ulefone rugged phone without any previous service issues

As a fellow Black View user and enthusiast any insights you can give I would be really very grateful :-)

Ulefone were not on the supported list of phone providers either for ID but I never had any issue with service before 

As a non techie, I just can't understand it. I just want it to work - consistently !

Saying that, my contact in the local Currys has been very helpful and patient, issued me with a new SIM, but we still haven't cracked it

It's quite maddening - D 

Hello Deirdre

Sorry, I can’t add any more, but one suggestion is trying a SIM card from another supplier, I’ve just moved from SMARTY.  If that works then it proves the phone is not the issue.

As I spend a lot of time on the water and have ‘drowned’ two phones in the past hence move to a rugged Blackview.  It has survived numerous tumbles and dunks in the sea.

Interestingly, my next phone will be a Ulefone, but am hoping my BV will outlive me.

For example, currently my phone appears to be linked to 4G - it says 4G at the top of the screen and I have four full signal bars but I can't make calls. I get the error message "network busy"

Likewise,  any text function - I get the error message "waiting to connect"

This is after doing a network reset
