Hi there ,
I have an s4 sgh m919 from tmobile and I live in venezuela I already unlocked the phone but it only receive EDGE signal because my carrier lte 4g uses the lte band3 (1800mhz) wich this phone doesnt have.
Is there anyway to "unlock" that band ? Or I have to buy the international version?

AT&T LTE ?

Does this phone has LTE? If so, is it compatible with AT&T LTE network?

[Q] Who works E250 modem/RIL port to N7105?

I have N7105 LTE model in Korea.
But Korea SKTelecom LTE band is 850/1800. Major LTE band is 850, sub band is 1800
All know that N7105 default LTE band is 800/1800/2600
So i want to flash E250 modem to my N7105.
(Just modem only flashing, because korean mobile operators are too many customized. I hate it.)
How can I E250S modem flash on my N7105?
Hopefully you get a decent advise, as i on the other hand have a E250 purchased in Taiwan, and would like to flash it to N7105 as reception in Canada with the current setup is horrible and LTE don't seem to work.

Oh, dears
Thanks for your reply and i know your pain.
LTE band problem is i know that Canada LTE use 1700/2100/2600.
So, if your carrier using 2600(Rogers) you will use only 2600, other LTE band 1700/2100 is not recognized your E250 on 7105 ROM.
Because N7105 only support 800/1800/2600 bands.(E250s is support just two bands, 850/1800)
Thanks

I wasn't aware of this when i was buying the phone ((((
On top of that, when i did the latest update i bricked/wiped all settings for the N7105, none of the ROMs through ODIN would take (i would get a FAIL message)i had to do Kies factory update which reverted the phone to E250.
Many of the ROMs would not be accepted by the phone, even after ROOTing. Still trying to get it on the acceptable level as the SKT setup gave me very poor reception.
Is there a way to change the modem operating frequencies by adding a ROGERS modem for example?

[Q] LTE on AT&T?

Once a custom rom is completed is it possible to turn lte on for the at&t network band?
IIRC the LTE model of the S4 Mini only has the bands used internationally and not the bands used by At&t in the US. This is a hardware restriction that cannot be fixed with software.
But, an LTE model of the S4 Mini with At&t LTE capability just passed through the FCC a few days ago so it may be coming to At&t:

Please don't make multiple threads for the same question. Especially when you have already asked the question is an existing thread.

I9195 LTE and AT&T Support?

I bought this because the reception on my S2 is just unbearable.
It's advertised as being 4G/LTE But it seems the out of box bands are every band except the ones North American carriers use.
Has anyone gotten true 4G/LTE reception on AT&T in America? I9190 model? I9195? Do the Qualcomm tools work for unlocking bands?
I'm sure 3G reception will at least be better than on my S2.
EDIT: Found the Answer. It has 5 LTE bands, none of which are used in America. So no 4G or LTE on this model in america. For anyone wanting LTE on AT&T in America get an SGH-I257M/SGH-I257 model. I just bought a motherboard off ebay. Also, apparently all I9195 roms work on I257M just fine.
