Going from OS5 to a used 9810
My apologies if I'm posting to the wrong spot/this has been covered a million times before, but after quite a while searching the forums and reading through the help section, I couldn't find a straightforward answer to my questions.
I'm looking to purchase a 9810 off contract, probably through eBay, the marketplace here, etc... If I swap the SIM from my 9000 to the 9810 without contacting AT&T (original 3G SIM that came with the 9000):
1. Will I be getting H+ speeds through my original unlimited data plan?
2. Will AT&T notice at some point and switch my plan to one of the tiered plans because of the 3G-fauxG difference?
If I have to contact customer service to have them add whatever is necessary to keep my grandfathered unlimited data, it's not the end of the world. I just figured I would save myself the hassle since someone here has undoubtedly got the answer, and I would then be saving myself the torture...

go to the AT&T store when you contact them. make sure that you dont leave until you are sure you got your unlim data plan grandfathered in. cust service via phone is a joke, and its contracted out overseas. I got mine done at Best Buy, and they were great about it.

Thank you. I've read many of the stories here regarding people having to struggle to keep their unlimited data plan or have it reinstated. That's the main reason for my questions. I'd rather not have to go that route if it isn't necessary, so I'm looking for feedback from those that have bought a used OS7 device (on 4G) and inserted a SIM from a 3G BlackBerry to find out if it is.

Ugh, never go to a store.
The 9810 needs a newer version (HSPA+) of your existing data plan. That's a simple change, and it is backwards-compatible with all previous BlackBerry phones. Even if you have unlimited data, there are newer versions of unlimited data made specifically to allow you to keep it, without breaking network compatibility.
Though anymore, there's little point in having unlimited data, since you get throttled when you breach 3GB of usage.
Good point. Though (not that I expect to go over 3GB anyway), I'd rather have the speeds throttled than pay overages.

And I agree stay away from the corporate stores if you can help it. I'm an indirect and I hear all the time how the people in the stores tell customers that they can't do something when in fact they can. I've also seven this first hand.

And unless you are tethering or streaming slacker or something all day long you are never going to have a data overage on a bb as long as you aren't on one of the 200/300 mb plans and even on them it's unlikely.
Thanks for the input. I'll heed the warning and call CS. I don't mind surprises, but not the kind AT&T would dole out...

Glad I found this thread as I am trying to get a used 9900 to replace my 9800 because the screen is partially broken. When I slide the slider open to get to the keyboard the screen goes dark, when I shut it it comes back on so I have to use the virtual keyboard.
I actually put my SIM in an unlocked TMobile 9900 and it worked but only EDGE came on, so I think my sim or account is not setup for their hspda+, so need a new sim or whatever they do to get my account the faster service. Will an unlocked tmobile 9900 give me those hspda+ speeds on my ATT service? I only ask because I know that an att iphone will not work on tmobiles fast network.
Not sure if you're replying to the thread in general or to Raistlin1's issue, but in their case the SIM (AT&T) is from a different carrier than the phone (T-Mobile), and the 3G/HSPA+ bands that the phone can utilize are not compatible with the plan associated with the SIM.

You dont have to worry about unlimited plan changeing. Plus you can go into the store. Just make sure they understand you do not want them to make a mistake and screw up your grandfather status. You will switched to the Blackberry ulimited child plan which is what we want. No worries. Plus I got a new sim card and thats recommended.
