There is a conflict on the LTE bands supported on the AT&T and HTC USA sites.
So is Band 3 (1800) supported?

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:

The ATT Samsung Galaxy S3(I747) has the Qualcomm Snapdragon S4 plus MSM 8960 processor. The Qualcomm MSM 8960 is capable of supporting LTE band 17, Band 4(AWS), Band 2 and Band 5. ATT has now launched Band 2 in NYC and Band 5 in the Midwest.
The S3 only supports LTE Band 17 and LTE Band 4(AWS).
Q1. Is there firmware that will make this device support LTE band2 and LTE band 5?
Q2. Is there a SW to make VOLTE calls using the S3?
I am looking to unlock LTE band 2 and LTE band 5 on my ATT GS3.
Thanks in advance,
Hi, I have a China Unicom version of M8, which is compatible with both 3/4G of China Unicom and China Mobile.
While now I am in the US and use a T-Mobile SIM, I wonder,
1) Can I change it to a T-Mobile version such that I can then use T-Mobile 4G LTE networks?
I currently can only access T-Mobile 3G networks (HSPA+). I checked that the China Unicom version M8 support FDD-1800/2100MHz 4G LTE band (according to HTC-China official site), while T-Mobile's 4G frequency includes Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz) (according to T-Mobile official site). It seems it should be compatible.
2) I currently cannot receive any Wireless Emergency Alerts message, is it because my phone is of China Unicom version? Then can I receive these messages by change my M8 with a T-Mobile Rom?
Thank you very much for your reading this thread and kind help.

Hi, I am living in India and using Samsung Note 3 Verizon SM-N900V, Android 5.0. Earlier carrier was Reliance CDMA and now carrier is Reliance GSM. I am unable to use Reliance LTE bands 3, 5 & 40 as Note 3 is not enabled for Indian LTE bands. Please suggest how can I unlock it for LTE bands 3, 5 & 40
Hi guys,
I know that HTC USA version has different LTE bands in comparison with European and Asian variants.
However what I want to know if the combination of bands to do carrier aggregation are different. For example, both devices support bands B7 and B28 but I don't know if both variations support using these bands together.
Google Pixel lists all the possible combinations of bands in order to get carrier aggregation but I can't find this information for HTC 10.
Do you know if American version support bands 7 and 28 together in order to get carrier aggregation?
