[Q] Vibrant 3g

---

Ok so i bought the vibrant, unlocked it, and inserted my att 3g sim. the issue is im only getting edge speed when my phone is 3g capable. any ideas to correct that? Like creating an apn of some sort?
Thanx!

im about 50 percent sure that at&t and t-mob use different frequencys or something for their 3g signals so they are not compatable, same thing happend with the nexus one and its 3g on at&t if my memory is correct

I second this.

Agree. U need to swap it for samsung captiva. The att galaxy s.

my only working theory is that the 1900mhz freq isnt as widespread as the 850mhz freq, as the vibrant uses 1900. (i think). so that may be it. but i ask only because some commenter on a diff forum mentioned the need to create a 3g apn.
ps. the captivate is too boxy for me. idk why att changed it

Those are at&&&-t frequencys tmob is 1700 and 2100 I think so if our antenna only picks up those iy wont ever work on at-t's network

It's not how widespread it is. They use different frequencies so your phone won't pick up the ATT 3G signals at all. Edge is 2G.

But I've seen one person on the forum claim that he did it. You can pm him/her on how to do it.

The Vibrant is capable of AT&T's 3G over the 1900mhz spectrum... if you live in a area where AT&T is only using the 850mhz spec... you will not get 3G.

HEY, don't listen to these guys. You can get both wcdma 1900 and wcdma 850 on the vibrant, don't worry, you will be able to get at&t 3G on your phone!
I'll show you how when I have time, maybe this weekend.

you gave the poor guy wrong information, the vibrant is capable of at&t 3g over 1900 AND 850
