Anyone switch from Int'l Version to AT&T?

---

?

Worried about data speeds as some SGS2 Int'l folks are complaining they aren't getting much better than 3g Speeds?

I'm getting 4.7 mbps up and 1.75 down on H+ in Dallas, TX

with int'l version or At&t version?

6.3 down 1.9 up. Fort Worth TX, euro version.

Sent from my Insanity powered SGS2

8462 kbps down 727 up in North Dallas, TX, on AT&T using AT&T's model on H+

so, it appears it does not matter which version (AT&T or int'l) version you use, you can still get close to the same download/upload speeds??

As long as the int'l version uses the same radio frequencies as the AT&T model, I don't think you'll have any problems with speeds. Make sure you get a new SIM card from AT&T for the "4G" network, though. My speeds increased fourfold when I got the new SIM card.

do you need to switch to a "4G" plan to get increased speeds (HSPA+)?

also, if you do, and if you are going to use an SGS II Int'l version, do you need to register an AT&T 4G phone to get that plan added? (i.e. an Atrix, Inspire, etc)?

I get 2mbs down and 1.5 up. Belleville IL. I have the 4g plan. Went to AT&T to check the Sim card and they said it was good.

Using AT&T version.

I think some have bad modems (just a hunch). I was just at my cor store because my speeds have been weak. Got a new sim, same speeds. Put my sim in my N1 and did a speed test against the floor model GS2. Out of 5 speed tests, my N1 was faster 3 out of the 5 (one by. 5Mbps and one by 1.1Mbps). That should not happen! I also put my sim in an Atrix and hit 6Mbps and the store manager even hit 7.2Mbps on his Atrix.

Anyone else noticing only 3G speeds on their GS2? I know its not my sim or my plan.
