If LTE bands are dependent on the physical chips that comes with it, doesn't it means that Nexus 5 should technically supports all LTE bands regardless of which region they are sold from? I highly doubt that there's any hardware difference that ships from google US, UK, JP, AU, etc etc. They must have come from the same factory but why the differences in the LTE band supported? Will software hack be able to enable those unsupported LTE bands in the future? Any guess?
As the title suggests, if a phone is listed as FDD-LTE 700MHz compatible, would that imply it'll work on T-Mobile's 700MHz Band 12? I am often confused with this band as it seems there's various other bands within the 700MHz frequency. So there's no positive way of knowing if it supports the band 12. For instance, I've been looking to find a cheap alternative phone (from China mainly) that might have support of LTE 700MHz so I can take advantage of T-Mobile's latest band, but I'm not sure on if it'd work. Couple examples of some phones are here:

That's just 3 out of a list of them found on Aliexpress. They all say FDD-LTE 700MHz. My gut is telling me the 700MHz it lists is for some frequency that China uses and wouldn't make a difference if used in the US. Just needed some helpful clarification. Thanks.

It won't. Most probably not, anyway.
When a frequency is listed as "700MHz", it's actually an approximation. For example, T-Mobile's band 12 is 700MHz Block A, which is 728–734MHz, whereas Verizon's band 13 is 700MHz Block C, which is 740–746MHz. This might vary from region to region too.
Most likely the phones you're looking at are compatible with 700MHz band 28, since this is commonly used in SE Asia and Oceana, along with the other bands they're listed to support. The Ascend Mate 2 you linked to however appears to support band 17 700MHz, which is an AT&T band, which would make sense as it also supports band 4, common in North America.
If you want a cheaper phone that has band 12 support, the newer ones from T-Mobile support it (or will, with a software update). Galaxy Avant, ZTE ZMax, the upcoming LG Leon LTE, for example.

Thanks, that is exactly what I thought. I understand the phones from T-Mobile will support the new band but I was looking for maybe possible cheaper alternatives than brand name phones to take advantage of it. I haven't heard of the LG Leon though, I will check that out. Thanks for the kind reply. I was expecting some "lol no dumbass it won't work" reply as this in General discussion.

The Leon isn't out yet, and only vague specs are available. No specifics on what the processor is, but I'd guess SD400 or 410. I'd expect it to be around $200-250, but that's just a guess. If it's more than $250, I'd say it's not worth it considering the low-res FWVGA screen.
It also occurs to me that the new 2015 Moto E LTE has band 12 support. 64bit Snapdragon 410, 1gb RAM, 8gb storage, microSD slot, qHD screen, and a relatively large battery. Honestly, I'd rather have this than either of those cheapo Chinese ones (yes, I know Motorola is Chinese now...). For $150 from Amazon, it's a pretty damn good deal.
Hello everyone. As many of us first posters here, I have a problem:
I've bought an north american J327U from someone I know, and that person only used it at home with their wi-fi. It's got an Exynos chipset, and no support for the LTE bands from where I live in (which are completely different from the USA's LTE bands).
After quite a bit of research, I found here and elsewhere methods to change LTE support for Qualcomm devices, but had no luck finding any for Exynos devices. Is there any way to do the same thing for devices with Exynos chipset, or am I stuck with no LTE? I also know it deppends on the hardware support for that, in my case I would need support for bands 3 (1800mhz), 7 (2600mhz) and 28 (700mhz). The phone covers none of those.
My device is not yet rooted, but I'm fine with doing so if needed.
Thanks in advance for any help.
I don't think you can physically change the bands unfortunately.
Hello XDA,
I was wondering why the Mi 10 Pro/5G and other phones using the latest Snapdragon chips only support limited CDMA bands? It was my impression that Snapdragon chips have the modem/cellular built into them. So is it just a lack of support via the software or do they actually have a separate chip that attributes to cellular signal/processing? I've been wondering this awhile but have been unable to find any information relating to this.
Thanks
The 865 has a separate modem, unlike the 765 which has an integrated modem (and runs at half the speed). It is my understanding that while the 865 is capable of all the bands, the OEMs select which to use per market. For example, the US has lots more bands than the EU. Hong Kong doesn't use band 20, so it's not implemented there while it is in the EU. You get the idea. As to why they don't just enable all bands and be done with it, I really don't understand either. iPhones, for example, seem to work everywhere.
This might be a dumb question but I had heard somewhere that network bands are actually licenced by manufacturers for certain regions and OnePlus decided to cut costs by only licencing two 5G bands for the OnePlus 9. If this is true than can those bands be unlocked manually by modding the device since I presume the hardware would have the ability for it?
It might be possible using this method:
