T-mobile K800i - Problem?

All,

Had a K800i for a few months now on t-mobile. I have had a problem a few
times where the phone won't dial out and/or receive calls for a while. Today
it has been much worse. I have a suspicion it might be when its been
switching 2G/3G. Its happened at at least 3 locations. Any views on whether
its a network feature, phone problem or what? Anyone else had a problem?

Thanks

Tony

I've had similar problems with an SPVC550 on T-mobile and GPRS.

At my home location it is fine most of the time.

In North Wales it will sometimes stop sending any data, can't make any
calls and refuses to reconnect to GPRS. Powering on and off or switching
into and out of flight mode fixes that for a while until it does it
again.

I had put this down to a SPVC550 GSM and/or WM 2003 problem: apparently
some HTC GSM stacks are notorious for this. Now I'm wondering if there
isn't a T-mobile base station incompatibility.

During the weekends it doesn't happen as much. Perhaps it is also
related to network congestion?

Are you sure it's not making calls? Or it's just you can't hear the speaker?
My speaker stopped working. So I was phoning people, not hearing anything,
but they were hearing me, and the screen didn't look as if it had connected.
Strange one. A 'master reset' (-all) cured it, along with another bug.

Yes not making calls- just get 3 beeps (I think) and incoming calls go to
voicemail even though signal looks fine. Has been better today but has still
played up a few times. I'm gonna keep experimenting a bit but would like to
know if its the phone or network to get it resolved! Maybe it is congestion
as its mainly happened lunchtime and 6pm ish. Still suspisious that it
mainly plays up when 3G symbol is displayed.

I dare say it's just T-Mobile's infrastructure from the sounds of it.

Bit of an update. Not sure if this is the only time it happens but several
times now i have been using the browser on the phone and it seems to stop
getting any more data. I quit and try and make a call, after several seconds
i get a series of beeps (3 I think) then making subsequent calls the beeps
occur instantly. Ringing the phone goes straight to voicemail. If I turn the
phone off and on it starts working again. Also when I have moved somewhere
and the phone needs to find a siganal again - it starts working again. These
problems, however, are in good signal areas. I believe it may have happened
without browsing too but I'm not sure.

I did last time try and pick up email on the phone and that too seemed to
'unlock' it.

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.
