I woke one morning and could not send or reply to text messages. I got
"Unable to send message" errors from the messaging app.
When I tried to place a call, the phone immediately went to "Call ended"
seconds after I pressed "Call".
Eventually (blush) I noticed that my phone was blinking between H+ and
E and no-network with minimal, non-zero signal strength.
After working with AT&T support -- both level 1 and level 2 -- they discovered that there might be troubles with my SIM card. When I got the
Inspire, I moved my SIM from a Captivate. Before that ... (blush) ...
It turns out that my SIM card was several years old.
After getting a fresh SIM from an AT&T corporate store, I've had zero troubles since. Also, I'm also getting better overall performance.
REMINDER Don't forget to copy your SIM card contents from old to new card. The stores can do that in a blink.
Hope this helps someone else,
