How to get 4G LTE to work with XT925?

Hi,
I just change provider to AT&T using my XT925. I don't see the 4G LTE logo. How do I know it is actually working?

Could someone tell me how to enable LTE in the XT925 on AT&T using stock rom or with any other rom? All I get is H+

Which country did you get your phone from? It may not support the AT&T LTE bands...

It is from Claro PR and the box says it is 4G LTE.
I only get H+ at less than 7 Mbps down and no more than 1mbps up. With my S4 I get between 6 to 22 mbps down and 5 to 12 up.
Any Idea what could be the problem. I'm using the stock ClaroPR firmware posted here and all I get is H+.

Any one there that could help me?

Hello, try 'notification toggle.apk', to force 'up or down' the 2g-3g-4g !

Claro LTE works on 07 band (2600 MHz) and AT&T works on 04 band (1700 MHz).

Yeah there are basically two versions of the GSM LTE RAZR HD - one supports 700 / 1700 / 2100 and I think is only available in Canada, whilst the other version supports 800 / 1800 / 2600, and is available in Lat Am and Europe.
Sounds like you have the second version, which as rafjak says, will not work with either T-Mobile or AT&T LTE

You can't use LTE, it's not compatible.

Too bad!
Thanks for clarifying that!

But can this issue be resolved flashing other modem?

Just flash a rom with the correct modem. I dont which one has the correct ones for at&t.
Or you can always flash a custom rom.
Sometime ago i was using brazils jellybean when i live in mexico. I just added mexicos modem files to the brazil rom.

I'm a little confused now! So does that mean that the problem could be fixed flashing other modem? If that is correct could some one point out which one should I use to work with At&t 4G LTE?

If the only problem is not having lte then yes.
The modem is flashed since the beggining. So you would need to reflash you rom.
You extract the modem file from what ever rom has the correct file had replace the one youre using. Or simply flash a rom with the correct modem file.
I had the brazil retail rom since it is bloatless from the get go.

Well I can tell that with At&t as provider I get H+ with data.

Can any one confirm if I could get LTE by flashing other modem and what modem should I use?
I just downloaded and tried Rogers Canada Modem and it did not work. All I still get is H+.

I'm using a Fido RAZR HD (original, not reflashed), and it works fine on T-Mobile LTE (same bands at AT&T I think).
Are you sure you have an LTE-capable SIM card? And also your plan includes LTE access? Are you using a direct AT&T plan, and not an MVNO (e.g. Aio).

Yes I'm sure I have LTE card and plan. I understand that T-Mobile Band is completely different from AT&T band... or am I incorrect?
I found this on Wikipedia and it seems that they are not so different. Can someone explain this to me?
Operator Country Frecuency (MHz) Band
AT&T Puerto Rico 700 c 17
AT&T Puerto Rico 1700 d e 4
Claro PR (PRTC) Puerto Rico 700 b 17
T-Mobile PR Puerto Rico 1700 f 4

So, I have LTE that only works on AT&T frequencies... I need it to work on the Europe frequencies 800/1800/2600. Is there a way I can change the modem files without reflashing? I got root, but locked bootloader... :s

I have the same issue. I have phone from Claro PR but I am from Europe. The LTE does not working due to wrong frequency.
Should I upload a new modem driver ? or should I flash my phone ? What is less harmful for my phone
My phone is rooted and I have unlocked bootloader.

Both 4G Volte sims

Hi Guys,
I am using a 4g+3g sim in my s7. I am planning to upgrade the 3g sim to 4g. Will both 4g sims work fine simultaneously?
Thanks

You can have data active only on one SIM. Also, no phone supports dual volte.

Thanks for replying. I am not interested in data. Can we enable 4g sims at the same time so that both can receive normal phone calls?

Well 4g does not support calling its volte that supports. As mentioned earlier no phone supports dual volte connectivity at the same time. As of now there is no phone chipset that does this.

[Solved] Nexus 5 doesn't support 4G network

Hello,
I have imported nexus 5 from USA to INDIA but i can't connect to 4G network.
Should i change LTE bands or what should i do?
please help me!!

You probably bought the D820. You wanted the D821. The difference is the radio and the LTE bands they receive. It's a hardware difference so you can't change that.

4G (LTE) works good on D820 here in India. Just follow the above thread.
