[Q] On AT&T - How to ensure it's using HSPA+ and HSDPA/3G

---

I assume that I'll need to call AT&T and give them the IMEI number of the GSII -- do I need to request anything special so that they provision the phone on their "4G" (HSPA+) network?
Do I need to tell them what model of phone it is?

I had an Inspire 4G in the past, but returned it in favor of buying this phone outright and avoid reupping my contract for a 'meh' phone in comparison -- I'm still grandfathered into the Unlimited data plan, and in the past when I had the Inspire 4G I was on their Unlimited 4G plan -- I guess do I just ask for the same?

Would it be easier to just take the new phone into the store -- I'm terrified of them molesting this new beauty.

Just trying to think ahead and be prepared for when this beast arrives (hopefully?) next week!

The area I live in does indeed have HSPA+ service.

Dont call atnt, ever. You dont need to in order to enable 3g. If your phone shows 3g (searches) and then switches over to 2g right off the bat in an area where you know you get 3g then you can figure you are on the euro bands. Unlikely but go into settings/wireless and see if you can toggle. Most likely you will need to root and then go to the hidden menu for the bands. Instructions for both can be found here in a search. Unless of course its working. lol If you see it staying on 3g run speed test if you dont mind. Regards report back, lots of folks want to have an answer with this one.

Gotcha. I've read lots of shenanigans that your IMEI has to be provisioned on their network for it to access HSPA+ -- I've also heard that you need a LTE capable SIM card to get on the HSPA+ network - which makes no sense, since HSPA+ is basically enhanced 3G.

You don't have to do anything, just pop in your sim card and go.

Do we have confirmation anyone using a galaxy ds2784 with att 3g yet?
