That does sound very similar to the symptoms I get with my SPVC550.
During the evenings and weekends it seems to happen less and not at home
(Stoke-on-Trent) at other locations (North Wales in particular) I get
problems.
Another syptom is using the phone as a modem with a laptop. When the
phone gets in this state the dialog box hangs at the "Registering your
computer on the network" dialog box.
I can think of a couple of possibilities.
One is that T-mobile base stations can send something which causes the
GSM stacks in some handsets to stop responding.
The other is that the base stations decide to impolitely "dump" some
sessions and then ignore them, possibly when the network is congested
and
GPRS more likely to get dumped. Then when the handset "logs on"
(whatever the equivalent is) again or gives up on the old session it
gets a new session and it all works again for a while.
Maybe this will get better when they update the network.
Steve.
