[Q] Not getting 4G speed on iWireless (Tmobile affiliate) using ATT SGS4

[raone26]

Yesterday I tried to switch to iWireless (a Tmobile Affiliate in Iowa) and to my surprise I was getting Edge connection from them on my unlocked ATT Galaxy S4!
I was aware about ATT iPhone working on edge speed if we use under tmobile but samsung too?

I tried the free method available on this forum to unlock the phone. Should I request a full unlock from ATT or this is (edge speed on iWireless-Tmobile) what I should be expecting even though I get full unlock from ATT (if the method I used is not unlocking the phone fully).

Are you sure you have 4g in your area? I have same setup and certain places even blocks difference only gets hspa.

Yes, I tried that sim card on my tmobile galaxy s3 and it was showing 4g (~4-5 Mbps speed)..

Unfortunately, for 4G, iWireless uses the AWS Spectrum (1700/2100) which the Galaxy S4 doesn't support. Even the T-Mobile version doesn't due to the switch to the 1900 frequency.

Next time if you want 4G on your phone, look at the Tech Specs and make sure under UMTS it says 1700/2100. If you want 4G, your phone HAS to support that frequency.

So I guess what jd1639 suggested in above lunk will not work based on what you are saying? Because if the hardware doesn't support then unabaling it wont work.

Any comments please.

I don't know, I haven't seen that. I guess you can try it at your own risk.

I have iWireless, and just wondering what your location is. ;P

If I'm not mistaken the MF3 update unlocks that freq. I'm pretty sure I saw in some release notes on either the MF3 or the one before that unlocked that.

I have no idea, I don't have a GS4. I have a Galaxy Nexus.

Already.... This is resolved!!!

I tried unlocking all bands based on the link above and it was smooth. Bought new prepaid sim card from iWireless. And woila a nice 4G sign on status bar and the speed justified the sign

Thanks too all who took time reply. I really appreciate it!!
