My BB was locked on the white face with the error message 545. I reloaded my OS 4.2.2 software exactly how it was explained in BB 101. Everything went accordingly, I didn't have the error message anymore and I was back to my AT&T home page. When I went to put in my sim in it showed "No Service". So I went into options and and under sim card and it was reading the number of my sim. I put in two other sims that I have (Vodafone, WIND) and I got the same result. I've tried battery pulls and nothing seems to work. If anybody has any advice it would be very appreciated.

Is the radio switched on ?

Go to Manage connections ( the icon that looks like a radio mast). Make sure you tick the box that says mobile network.

when you first reload the os the radio usually stays switched off so gritmaster is probably right

I went into the manage connections and turned on the radio and all it said was searching for network. Then after awhile it stopped and said No Service.
