Default TMO roaming on Cingular's 850 network

Please Login to Remove!

I'm currently on Cingular with my 8700, but am trying to evaluate whether I could do TMO. I had TMO before but was unhappy with their coverage in less urban areas.

With Cingular, i know that the 850 band covers those areas and really do use it quite frequently.

Does anyone using TMO that has an 8700 or other device that has 850 band know wether you roam on the 850? If this is not restricted, then there is no reason why the Cingular coverage would be superior, is there????

Default You hit the nail on the head

As I have seen people talk about the debate between the two it seems to come down to cost and features vs. coverage. For those in a corp environment with bills being paid, Cingular seems to win out due to coverage. I have read here that if there is any T-mobile signal, you won't move over to the other network. I am not even sure you can force another carrier on the 8700.

In our corporate environment, we stick with T-Mobile because of their technical support and international roaming agreements. I have been to several places where tri band T-Mobile devices have no signal and my 8700 (or before it, the 7100t) roam onto Cingular onto 850.

If your 8700 is unlocked, perhaps you can buy a TMO pre paid SIM and go test the areas. I know prepaid won't roam but it will let you know if TMO works in the area.

NJBlackberry,
Next time you roam onto Cingular, can you check whether you get EDGE? And, of course, the key thing I want to use is tethered modem from my house in the mountains of NC - there is no TMO there - it is all Cingular roaming - one of the reasons I thought to just do Cingular anyway.

Soapm,
Didn't know you could not roam with prepay - is that always the case? I thought prepay advertised roaming capability.

Default NJ, please comment

If there is any TM signal, will your unit stick with them, so if it's weak, you can't get to what might be a stronger Cingular signal at that spot? Just curious so I can advise others at my firm.

I don't blieve you can roam if there is a weak signal. If your carrier services the area, the other carrier cells will probably reject the request.
