I have an unlocked 8700c and am using T-mobile. However, inside my house, I get bad service. T-mobile users cannot find service at all, however cingular users can. If i put my phone on manual and check available networks, I see cingular, however when select it and put it to the top of my network list, it won't connect.

Is there anything I am doing wrong? I've tried rebooting it, and it still won't work. I even tried outside where both services work great, and I still can't get onto cingulars network.

Maybe Cingular has something personal against you.. I mean after all, you did unlock their device.

I could do it fine on my 7290. Is there something I can change on the 8700?

I'm not doubting you (well, I am, actually), but if T-Mobile has coverage - even weak - in an area, you can not roam onto Cingular. They have roaming arrangements in areas where they have no coverage (like in the US Virgin Islands, where T-mobile has nothing), but not in your house where the signal is weak. You are locked onto your home network.

Sorry - I just don't think it works that way.

If anyone else knows differently, please chime in.

I agree. But one thing I want to know is that if his 8700c does show the netwrok selection ability on it.

It shows the network select only with a t-mobile sim card. when i put a cingular sim in, it doesnt show a thing


what does the H and X mean next to the networks? When I have my t-mobile sim, in, the tmobile network has an H next to it, and the cingular has an X. these are available networks, so i dunno what the X would mean. when i try to connect to cingulars, it says it will do emergency calls only

H is for home and X is meant not allowed (blocked) to lock into it. So like was said by NJBlackberry T mobile does not allow its users to roam om cingular in your area.

anything i can do about this? if i asked tmobile would they change anything?

I dont get why not... if i roamed, im still paying tmobiles bill

Um, because TMO wouldn't get the full amount of your usage. Part of it would need to be kicked back to Cingular.

Exactly and why would they want to pay some one else for the minutes that you use for free. It will cost them big if they did that in every area. So basicaly if there is some T mobile service in an area then they are not going to allow roaming. This holds true for all providers.

Tonight I have the experience of roaming with my tmo on the cing network in SC,1st time I've ever been able to.I am on I-95 Miami«=»upstate NY.
Glad to see the roaming agreements!
Still scratchin my head why the posters 7290 will allow him to lock cing and not 8700...guess the crew missed that part--

No, the Cingular SIM cards (64k) don't allow you to switch networks. The T-Mobile cards DO allow you to try and switch networks, even in the US.

He was using TMO Sim on the 7290 and the 8700. The 8700 wouldnt allow him Cingular access, yet the 7290t would.

I had a simular experience on my recent return trip when I came back thru the Carolinas, headin home. My 8700 had an X by Cing, No Tmo coverage, yet wouldnt allow me access.

Must be a logical explanation. ( although havent seen one yet )
