850 roaming is truly only available where T-Mobile doesn't have coverage. They will indicate on the coverage map where they will have roaming available. You can't force 850 roaming in most cases, either you have it or you don't. Many phones don't even let you see which band you are using. You may see another carrier's logo on your phone display but that also depends on the roaming agreements in place.
For example I know that some parts of "native" T-mobile coverage are really areas where T-Mobile has negotiated coverage with the carrier for a particular area. In these same areas if you were to manually select a carrier you would see both T-Mobile and the roaming carrier. I know I've been able to select both in some of these areas. Of course just outside the "covered" area the phone will switch to the roaming carrier's logo and so on. Frankly I'm surprised you analog sleeve still works. T-Mobile supposedly had discontinued that service some time ago. In fact I had been told by people that had the sleeve that it no longer worked. Maybe you were one of the lucky ones. 850 roaming is digital roaming so in many cases, but not all, you will have all or most of your services you would normally. Text messages will always come in but you may not be able to browse online, receive mms or otherwise have data services. Data services aren't an issue with an older phone like the 6190 but newer phones would have these options.

First let me tell you what I'm using now, so you know where I'm at. I use a Nokia 6190 with Analog sleave and analog roaming, so you can tell I've been with T-mobile since the Voicestream days. I actually signed up in 1999. So I'm a little out of the loop on the newer technology. What I'd like to know is the 850mhz roaming in the rural areas anywhere as good as the old analog roaming coverage wise? On the newer phones can you force them to search for 850mhz, and last is there anyway to know that you are roaming on 850mhz or does it just say the network name in the phone screen like when your roaming on 1900mhz? Since cellular providers are no longer required to keep there analog networks up after the first part of 2008 I figure I better look into other roaming options. I use the Analog Roaming alot when I'm in the Rural areas of eastern Washington. Thanks, Rob - - T-Mobile-US on Google Groups: http://groups.google.com/group/T-Mobile-US _ _ Yahoo!
