My wife recently switched to an iPhone, leaving me with a Samsung Infuse 4G. I have an old Nokia XpressMusic, and figured I'd give this new phone a try. My existing SIM card is labeled "3g". I tried placing it in the Infuse 4G, and the phone portion certainly works, but I cannot access any network services.
I'm guessing this is because my old phone is 3G and works off of the AT&T Media Net GPRS network, and the new phone can't operate in this way. Or is there a way to make this work? I'd love to use this new phone, but I don't want to have to upgrade my current plan. I don't really care about speed, I just want to be able to check email while I'm out and about.
Thanks for any help that you can provide!

OK, I figured as much. So there's no way to enable an older, slower network access mode with this new phone?

You should be able to use the SIM card, but need to activate a data plan. If not, you can go to any AT&T store and pick up a new SIM card, usually for no charge.

To clarify, I already have a data plan on the existing account, but I'm guessing AT&T is smart enough to block smart phones from being able to use the older data services. I just wanted to check to see if there was anything I was missing.

The problem is ONLY that you APN setting are wrong.
"Google" APN setting AT&T
and you'll find some tutorials.
When you put a 3G sim into a 4G card the APN gets
dummied up. Probably done on purpose by the MAN.
I've successfully fixed this moving a 3G sim to a Samsung (?) w/Keyboard.
I even get 4G data packets. AND I'm on PREPAID to boot!!! :-)
Wish me luck that they don't track me down and disable my account!

The old non smartphone data plans use the wap. cingular APN and your phone is set up to use the PHONE APN. you need a smartphone data plan because even if you go around it they'll catch on and add it anyways
Would he also need to get re-provisioned to go from the 3G network to the 4G?
I know that was an issue for me when I went from my Captivate to the Infuse. Although I already had the "smartphone data plan."

Does pre-paid vs post-paid make any difference?
It's been a while since I had a Go Phone account, but I wasn't sure if Go Phones have 4G phones available?
Now I'm pretty sure you can take a 4G phone, but it outright, and use it on the account, but I'm thinking a problem could arise if the phone is always seartching for a 4G signal when you SIM Card is not provisioned nor the account is set up for it.
Looking on the website I didn't see any "official" 4G phones for sale.
