Are they both using GS2 skyrockets, I am a little confused sorry. Don't know if they are using regular GS2's or GS2 skyrockets. If they are using skrockets, it is because of LTE and Galaxy Nexus is only HSPA+

 

Yes skyrocket has LTE module and if you live in LTE area they should get between 20Mb/s and 40mb/s. I switched from skyrocket to nexus and my speed went down to 5mb/s and 1.5mb/s up which i find ok for my needs.

Why did you give em your IMEI number? At&t is so greedy company you should never trust them.. now they know you're using unbranded att phone. They will make sure your service isn't good so you would go out and buy a new phone from them.

 

not sure about any ATT conspiracies to mess with speeds but it is well known that the nexus isnt close to other phones when it comes to the radio......its just one of those things you have to deal with.....

 

You are never going to get much more that 5mb on hspa+ on the Gnex or for that matter any phone. I think your slowed speeds might be because you gave them that crazy IMEI number. They are giving you service for the wrong phone. Just a thought. I would never give them info about my Gnex. They have no idea that I have mine and I want to keep it that way.

 

I would not doubt if they were doing something since its not an AT&T device. I have a GSM Nexus running on Straight Talk AT&T and my speeds are not all that great. I was thinking of going directly to AT&T but after seeing your post, dunno if its worth it.

T-Mobile is an option I am considering however.

 

It was a joke lol! GNex has no relationship with at&t and i dont think at&t tested it on their network.. It might need some tunning and so on. Back in 06 i got myself European unlocked nokia n90 to use it on att network. It was a 3g phone but i never saw a 3g icon. Not to mention the radio reception was horrible.. I could lose it on the open field surrounded by att service towers.. I used till apple released the first iphone.

So it might be just that and consider the fact that we have more than 2 major gsm carriers in the states(and the rest of the world) the phone just cant be tuned for every carrier so it would work properly.. Google prob. just took basic settings and shipped it.

Att and other gsm companies have their phones specifically built for their networks

 

Agree with this. Another reason I may switch to T-Mobile but again, I myself use wifi a lot so its not always a huge issue for me. As long as I have enough data to use GPS when I am driving then I am a happy camper.

 

Ok so I thought you said that you gave them IMEI in which you changed the numbers? Also if you gave them an IMEI for a GSII then things could be kind of crazy. You could be getting only 3g speeds not 3g+ cause you gave an IMEI for the sII.

 

There are areas where I get 8-9Mbps pretty regularly.

To the OP, are the SII's in question capable of HSPA+42? If so, I believe it uses multiple connections to get the extra speed, so even in an area with speeds well within the theoretical max of an HSPA+21 phone, they would likely be faster.

I could be wrong, I've never owned ah HSPA+42 phone. But my understanding is, say in an area where you can get ~5Mbps on a normal HSPA+ phone, they might be able to get closer to 10Mbps with the same signal strength/etc (assuming it wasn't the backhaul that was the limiter).

I have tried my GNex on an ATT sim just to see what speeds were like in my area. But it was out of an old Blackberry, so it wasn't that relevant to compare data speeds between devices.
