Anyone have experience switching from Cingular to Tmoble on the same 8700c? I am going to get my phone unlocked and since Tmobile has better rates I will switch after testing with a prepaid SIM card.

Any special settings that I will need to do? Any special problems I need to consider before doing this?

At a savings of about $30 a month for the same (and some increased) benefits, I can break even after my early termination fee in about 6 months.

Thanks

Welcome; many of us have done the same thing.

Are you using BES or BIS (or both). If you are using BIS you are going to have to have Cingular (or RIM) release the IMEI/PIN from the CIngular BIS you it can be added to the T-Mobile BIS.

Get a T-Mobile SIM card provisioned with the BlackBerry Data Service and you should be good to go!

That's really about it.

I'm using an unlocked Cingular 8700 with Tmo on BIS. When I activated the 19.99 email service through the internet, it asked for the imei # which I found on the box or inside the battery compartment, then the service came up within 30min with the Browser and Tzones icons. So far everything good after 3days.

Just make sure T-Mobile works where you use the phone. Cingular coverage is generally regarded as being much better than T-Mo. Just because the rates are better, if it doesen't work where you live, work, travel, play, etc. then it doesn't do any good to switch.

I have a prepaid Tmobile SIM that I am giong to try (after I have it unlocked and before I switch). I get really good reception from Cingular in my and the maps show that I *SHOULD* get good reception from Tmobile (but I am still going to try the prepaid first to make sure).

Thanks for the reply everyone

Welcome fellow SoCal user!! i'm in Long Beach every once in a while and I've never had problem with reception in Long Beach.

When I had my phone(s) out in Socal, it'd always say Cingular as the service provider, and I pay T-Mobile. So it looks like they're using their towers, so coverage should be the same.

Theres nothing like trying it out for yourself. Tmo gives you 14 days, give it a shot and see how it works.

Anyone had issues in Boston, MA area. I heard that Cingular actually has two networks the orange and blue. most people are on orange after they bought out AT&T but i have heard alot of people complain about the network and drop calls bad reception issues and have gone and had Cingular switch them over to the blue network. Anyone know any more about this.

Debias - 1) please don't double post. You have posted this in at least one other place. 2) Do not hijack a thread; your question, while valid, has nothing to do with someone switching from Cingular to T-Mobile.

Thank you.

I'm actually thinking about doing the exact same thing, but in Fort Lauderdale. I'm paying $140 a month for 1000 minutes and unlimited BB service with Cingular and could be paying half that with TMo.

Obviously, the service issue is something that I'll have to test out, but my question has to do with Cingular releasing my IMEI/PIN. If I do make the switch, I'll have to pay the penalty fee for breaking my contract, which would still be cheaper than staying with Cingular (plus, I'll have to unlock my bb). But, if I do pay the termination fee, will Cingular give me a hard time about releasing the device? It sounds like the shouldn't, but sometimes they get funny about that stuff. Actually, now that I think about it, if I pay the termination fee, would Cingular unlock the device for me?

actually, you have 30 days in Cali

Long Beach is like LA, they have everything. I live near Big Bear and only Sprint works at my house. Verizon works at the end of the driveway. Cingular works five doors up. I wish his country would get consolidated on wireless!
