Help How to get 3g on t-mobile?

[Arsis311]

Hi everyone.I have a problem and I looked everywhere and I didn't find any answer for my problem. Almost 1 month ago I bought a HTC Incredible S S710e international version from amazon and I have t-mobile with unlimited web plan. When I turn on my mobile network on WCDMA mode I get H (HSDPA) and when I change it to GSM mode I get E (EDGE). Very often when I'm using WCDMA mode I get 3G. I know my phone support 3G on t-mobile but I don't have 3G. What can I do to have 3G always? I live in Los Angeles. If anybody know please help me.
Sorry for bad grammar and writing because English is my third language.

did you set the APN? if not, set it to epc.tmobile.com.

yes it sets.

ok.. but actually, if you leave the network mode to "GSM/WCDMA Auto", then it should work fine..

It works on mine.

it's still H.

"H" is T-Mobile's 4G.

"H" is T-Mobile's 4G.

it means i need to leave my phone on WCDMA mode? but i need something better than E (edge) on GSM mode because on WCDMA mode i don't have very well signal but my internet works good.
