@als --- Hope you're better tomorrow. I suppose you have already tried this, but once when I was signed onto a $3 T-mobile plan, I couldn't get the phone working from the get go, and called CS and got the same info you did. Only when I powered off the phone, took out the sim, though it was inserted correctly, reinstalled the sim, and powered on the phone did it start working as it should. Why it then worked, I do not know. Also, probably unrelated, there was a big Verizon outage on the east coast yesterday where customers were unable to send texts, a problem that has now been corrected.
