Hi!, good night, i live in Mexico, and i'm trying to use Nextel micro sim card with no success. This indicates that my Meizu MX4 Pro is not good for this network. I want to see if there is any possible way to add/activate other frequency bands if the hardware is not a limitation for it. I found a tutorial made for Qualcomm devices. Sadly, this devices have an Exynos processor. Is there any possible way to achieve this? Thanks in advance!.

First sorry for my english, i will explain my doubt with a little introduction.
I have been readying about unlock bands of Qualcomm devices, i have a ZTE Grand S2 s291 (best page for device spec, in my opinion http://www.devicespecifications.com/en/model/b66b2a5e), the important thing is that it has a Qualcomm Snapdragon 801 MSM8974AB. If i understood well with the information i read, the snapdragon 801 processor has an RF Qualcomm RF360 (https://www.qualcomm.com/media/documents/files/qualcomm-rf360-front-end-solution-product-brief.pdf) , means that you have all hardware support for 2G/3G/4G LTE frequency bands, from 700-2700mhz.
Well, i want to know if i'm right with this information, in the begin of my little poor investigation wanted to know which is the component in the smartphones that limits the support of different frequency bands, and i guess in this case is Qualcomm RF360. I wondered this because, all the tutorial said how to unlock bands of Qualcomm device in general.
I unlocked the bands in my phone, but certain frequency bands can't test if are working.
Thanks in advance, any help it will appreciated.
Regards!
Please confirm if i'm wrong or not, i write this thread for helping people that are in my same case or when you want to buy a new phone that is not supported by your country, and you need to know if the frequency bands may be unlocked.
Hello,
i havent found a Meizu m2 Group, so i wirte it here.
i need to know what FDD LTE frequencies the new Meizu m2 Note (not the m1 note) support.
its a MediaTek MT 6753 processor inside. This should support many frequencies, but if havent found any inforamtion about which frequencies.
Meizu Support doesnt help (no answers since 4 weeks)
isnt there a chance to activate all LTE bands via software upgrade ?

I think yes because elephone P8000 is using same processor and it has FDD-LTE 800mhz support ... I had to buy a elephone p8000 instead M2 Note
Hi,everyone.
It may be a foolish question. But I'm not a pro (both in unlocking and English), and I'm not sure if there is a little possibility. Here's my question.
I have a redmi note LTE(Qualcomm) and I bought the chinese TD version by mistake, the network provider's frequency works on WCDMA/FDD- LTE.
And TD version supports GSM/ TD-SCDMA/TD- LTE but FDD ver supports GSM/ WCDMA/ FDD- LTE/ TD- LTE.
So Now I'm using GSM?
I found that both of the TD and FDD version are using same hardware, so I'm wondering if it's possible to unlock it?
Thank you!
Its not possible. Fdd and td have different hardware.
As Killerrade said you can't unlock a frequency, it needs specific hardware which it doesn't have. It's not like when carriers lock it.
@Killerrade @PeteSco
Ah how awful I can only use 2G…
Anyway, thank you guys for replying, at least I know it is impossible now.
Oh almost forgot, Happy New Year!
So there is a version of the Redmi 3s and 3s prime that is sold in Mexico that supports 4g lte (called only 4g in here)...
I was wondering, does it have different hardware? Or were the antennas for mexican 4g already there and activated via software?
I'm really confused on the subject and can't find any info as to why some xiaomi phones work with mexican 4g(Which uses some bands that are also used in the us).
I'm considering buying this or the 4 prime and was wondering if there could be a way to activate global lte on the 4 primer later on.
I was also wondering if I NEED to buy the phone in here to be able to use the 4g or if I might be able to pick up a phone from aliexpress and have 4g too.
Hope someone can help me with this info
The hardware is different but you can also get the LTE (4G) version for Mexico on Ali Express.
In Mexico you use LTE band 2 (Movistar: 1900 MHz) and 4 (AT&T,TelCel: 1700 MHz). So when you want to buy a Redmi 3S on Ali, make sure you buy the Xiaomi Redmi 3S Special Edition. It supports the LTE bands needed in your country.
!!
Thanks! =)
I was reading on sites that list the specs of the device but couldn't find anywhere that said that it supported lte bands 2 and 4 so I was quite confused. Thanks a lot.
I got a question . I am from Romania and i bought the chinese 6/64 version of Redmi Note 7. Will the 4G work in Romania? My network provider is Orange. How can i check this info?
Are the chinese and global version same when it comes to supported 4G bands?
And the second question is if you can install the global rom on a chinese version of Redmi note 7? Will the B20 for 4G be automatically unlocked when installing the global rom? Those accepted 4G bands are a software or hardware thing ?
Thanks in advance.

check this out mate, it says here that the Chinese RN7 with LTE band B3 and B7 will work on Orange Network.. here's the link if you need all the info's regarding RN7 technical specs and comparisons. just navigate with the page and you'll find your answers:

B20 is available to Global version but not in Chinese variant..
Unfortunately, changing ROM won't change the modem ability to connect a band that it is not designed to manage. So, yes it is a hardware issue. The modem of the CN version of the Redmi Note 7 is probably able to manage the B20 technically speaking, but it doesn't have the proper embed instructions to do so. I have read some posts about flashing the modem. It is sometimes possible (when there is no hardware limitation), but honnestly, it is not something you can envisage to do by yourself right now, and until someone with good skills does it and share the method (if someone decides to challenge this someday...). The instructions are coming under binary codes. This is a real quest!
Buying a cellphone that doesn't manage the B20/800MHz in Europe is really a bad idea. B20 is the golden band in Europe, since this frequency allows the most performing penetration indoor, and offers the best distance range (about 15 km around the antenna communicationg on B20/800MHz versus barely 5 km around an antenna communicating on B7/2600 MHz). While using your phone in big cities, you will probably catch a B7/2600MHz or a B3/1800MHz signal on your network. But globally your experience won't be good. In many places where your friends using the same network will have a good signal, you will sometimes have a low signal or just no signal (or a switch to the 3G network). For example, when I check my LTE info right now, in a very dense area (Paris, where my network operates from B3, B7 and B20 antennas), my phone is connected on the B20. For sure, if my phone didn't manage the B20, it would connect alternatively to another available band. But if it "chooses" the B20, it means it's the best signal, so.... And now, imagine when you go to the countryside, where there are lessa ntennas, without being able to connect the antennas running the long distance range frequency... This can't be better.
Good luck, though.
