Hence why I said AT&T needs to have a "roaming contract" and regardless it will NEVER work on Verizon as you stated as their equipment is not capable of sharing with AT&T equipment.

The joint use agreements extend to greater granularity than the towers. Agreements are frequently arranged to place antennas on other provider towers. The use of Verizon as an example should have been further qualified to the level of antenna placement or other compatible antennas on those towers. The cell network is far more complex and in place with sharing agreements to control investment and to keep the number of towers to a minimum while achieving adequate coverage. Placement of towers is controversial in all communities. Customers want adequate coverage, but not the physical tower in their back yard.

So, yes OnStar can get service off a Verizon Tower, if that tower has a compatible antenna through a joint use agreement and many do have that in place.

The cell providers may compete for customers in their advertising, but behind the scenes there is a great deal of cooperation to provide adequate coverage as mandated by the FCC with the fewest number of unattractive towers.

On a recent vacation on the island of Kauai, the tour bus driver pointed out a Verizon Tree. It was a Verizon cell tower covered with artificial evergreen bows in an attempt to make it blend in with the scenery. It did not come off very well aesthetically, but my AT&T cell phone worked just fine getting service from that tower (obviously with the appropriate antenna).

GSM wont work on CDMA networks and vise versa. It's like trying to run your gas vehicle on diesel...not gonna work.

So unless there is a tower that is GSM capable and it either belongs to AT&T or AT&T has a roaming network contract with the owner of that tower, THERE IS NO SHARING. Carry On
One addition.... Gas WILL run on diesel, and diesel will run on gas, albeit VERY POORLY and may damage fuel system parts... Whereas CDMA and GSM won't even connect to each other because of the freq band's they work on. The networks that's aren't compatible with the hardware won't even show up when you populate a list... If you have site survey equipment you'll see everything around you

Does any of this really matter? Either I can or can't connect, anything beyond that is really irrelevant as far as I'm concerned...

I can say that I have seen this personally... It was in Iraq running the pressure washers... The solider put wrong fuel in the pressure washer. The engine was hot and the fuel lines didn't completely empty of gas. It ran for about a minute then smoked real bad and died. Ultimate cause was a wet fouled spark plug covered in diesel... Brake clean the plug, drain the bowl on the carb... No harm at all.

When you're in Iraq, and you have limited places to store fuels.. Sometimes diesel gets put in a red can, it happens more often then you'd think

My comment was more directed to the Cell Tower argument, but I did have an opportunity to see a diesel tractor self destruct when someone accidentally put gasoline in the tank. That wasn't a pretty sight...
