Xperia Go on Tmobile USA

[Arkenstone]

Hi all,

I have an unlocked Xperia Go and on the Tmobile USA network. They have recently (early 2013) refarmed their 4G, which is HSPA+, on the 1900MHz band. So in theory I could get 4G on my phone.

The problem is, all I can get is EDGE...

Does anyone have a solution to that? I went to my local Tmobile store but they couldn't figure out. Would it help to root the phone?

Thank you!

1st HSPA+ its NOT 4G, if anything its 3.5G

2nd LTE is 4G 

3rd which Xperia Go model do you have? the "i" or "a" version?

Don't forget the Kudos 

[Arkenstone]

That was fast! Thanks!

Alright, 3.5G then. Anything better than EDGE is fine to me, and this is much faster!

I have a st27i version.

Ok so you have the Xperia GO 

3G HSDPA 900 / 2100 - ST27i

it should work just fine with Tmobile, do you have the correct APN settings?

[Arkenstone]

I believe I do.

APN: epc.tmobile.com

MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc

MCC: 310

MNC: 260

APN protocol: IPv4

Bearer: unspecified

Network mode: WCDMA(preferred)/GSM

Also, i have android 4.1.2 running. So yeah, I have no idea why the only network it detects is 2G. I live downtown Tucson, AZ, it is supposed to have pretty good coverage there.

Thanks. But that's what I had already.

Would you or anyone know of any other possible reason?

[Uliwooly]

my bad, yeah it is not going to work, why? simple

3G HSDPA 900 / 2100 - ST27i

Tmobile USA use 1700-2100 (both are needed)

so you will be stuck on 2G/Edge with Tmobile

now it seems that 1900 is for 3G and 1700 & 2100 is for LTE (combined)
