Blackberry Pearl Troubleshooting "SIM Card Rejected"?

[EllBell]

I have a Blackberry Pearl and my service bar says "SOS". Also, my phone is saying SIM Card Rejected. I dont think i'm getting texts either. What's up with my phone?!?

Try switching it off and on. Works in my case.

Well, my phone all of a sudden said SIM card rejected. Did the battery in and out, and phone off and on thing with no luck. Now when the phone is off, but charging, the light is green which iv never seen before. anyone seen that before.

I'm having the same problem, but the green light while charging when off is normal...I've tried taking out my SIM card and battery...replacing them, off and on...doesn't work. Tried doing manage network options, to no avail.
