I have a SIM-free 8X currently in use on Vodafone UK, and when I attempt to access Connection Setup, which to my knowledge has been there since originally got the phone when it first came out, I get the following error:
"Warning: There is no SIM card, PIN code has not been entered or the phone is in airplane mode. Please insert SIM card, enter PIN code or turn off airplane mode to use Connection Setup".
That is strange for the following reasons:
1. There is a SIM inserted and it is online. I have all network services available.
2. No SIM card PIN has ever been in use on the SIM, nor a security code on the handset.
3. Flight mode is not active.
I only wanted to try it to see if I have Data Sense available, so that I can attempt to tell which update my phone is currently running!
