I have a new ZTE Visible R2 and when I shut off and restart the phone it claims no sim installed.
Some times it fixes itself and some times it takes rebooting several times.
The last time it took an hour checking this and that to get any data.
Could this be a bad Sim or phone?
Thank you and merry Christmas
