Phone, Service Area, or SIM issue?
I notice that when my P800 has sat in a bad cell area, for no more than a just few seconds sometimes, I loose sync with T-mobile. My GPRS shows active, and the GSM signal strength meter has a bit of a signal, yet the status shows no network avail.
It happens very rarely when im out and about, and its not like I have the woodpecker wav file telling me i have no signal at all....I just go to dial a number and it fails and fails.
Now here is where it gets funky, in my opinion. Sometimes if i retry like 5 times BOOM all of a sudden my meter goes full green and i can make calls....however sometimes,,,If I reboot the phone, or switch from phone to flight mode and back again to reinitiate the GSM it works just fine again showing a full green meter.
I read something like this about a t68i and it ended up being a bad SIM card. However most of the time this happens it happens in an area that has a known weak signal.
Has anyone seen anything about our GSM signals timing out, is there something im missing on the advanced settings on my phone? I have tried setting my MNC manually, but after a reboot it goes right back to the default listings in the GSM search path.....
Any help would be nice.....TIA

I never once had to change anything just by swapping sims, its just a test, don't mess with the phonebook and you will be ok.

i'm having the exact same problem, and i'm on my second t68i from tmobile. this phone is worthless at this point. anyone who has any tips for fixing reception and signal problems please come forward.
oh, and the sim is fine. works perfect in at least two other phones (not t68i's)

actually the fault is neither SIM, Phone, but really area location.
The signal strength is only one parameter when it comes to whether your can made a call. Should nearby "cells" be full to capacity, u will also get a "no network" or "network busy" when you try to make a call, even when the signal strength is adequete. which is why you sometimes get 3 or 4 no network, then suddenly can make a call with full signal, someone else was booted off to give you space.
Another reason for why you see "no network" yet the signal bars are showing a signal is that when the phoen cannot get a good signal to log into your home network (in this case T-Mobile) and instead is polling all other networks too (Orange, O2, Voda), so that if you were to make an emergancy call to 999, it will use the strongest network possible. The signal bars during a "no network" phase is simply showing the strongest signal it can recieve. Its common with all ericssons, and in the olden days, the phoen woudl show a message saying "emergency or SOS calls only" on the screen during this phase.
Last year i had the need to call 999 and i had no signal on t-mobile, yet when i made the call it did use another network to connect it (i think it was vodaphone network it used since that was the strongest signal in that area)
hope this helps.

Its a network problem. When signal is weak the phone hangs literally on the network-thats why u r in and out frequently.when restarting u force the sim to re-register into vlr(a prog used by the gsm netw) thus letting u call.make a formal complaint to ur provider-they can rearrange the antennas by a few degrees maybe the area will get a better coverage.
