Hi,
I constructed my Ringo phone and it starts fine. The SIM card was found (code pin ok), but I cannot connect to my operator Swisscom in Switzerland. I tried the fonction Loading operator and now there only Loading operator on my scren and Ringo does not respond any more.
I need help.
Thank you

Hey POV,
Did you try to turn off the phone and turn it back on a couple of times?
It resets your SIM module and it can be an easy fix sometimes.
Also, try to get outside of the house or close to the window to get that first connection.
If these simple fixes don’t work, tell me so we can try some more advanced stuff. 
Cheers,
Robert
