Hi everyone,
I'm new to xda-developers forum and hope you guys welcome me to the community .
To be honest, I actually registered on this forum because I had a problem with connecting to a 4G network.
I have a Xiaomi redmi note 3 special edition and it supports TDD LTE 2300Mhz band. I also have my internet connection which is also on a TDD LTE 2300Mhz network. ISP has provided me with a device (a huawei router) along with the internet connection and I can use that SIM only on that device, although my phone supports the same TDD LTE network band, ISP network refuses to register my phone on the network when I've put the SIM into my phone . So, here a question arises, How do they identify the device? Can I trick the network to show them my phone as the router they have given? :silly: I'm pretty sure they not only use the IMEI, (I've tried changing IMEI with another device. It didn't work). So what else they can use to identify the device trying to register on their network? Serial No? or is there something else to identify a device on a TDD LTE network? I hope all of your support on this. Could you please share your knowledge on this topic? :fingers-crossed:
Thank you

Howzit guys,
I brought a HTC Aria in the USA on AT&T network. I came back to SA and rooted my phone put Android v2.2 on (phone came with v2.1) thinking that would unlock the phone, but it didn't. I ended up looking on the net for a website that I could get an unlock code for my phone. Long story short, I found one, paid for it and it worked. I'm using the phone on Vodacom no matter what I do I can't get 3G or HSDPA to work, only GPRS. HSDPA and 3G work fine in the states.
After doing some research I noticed that in the Mobile Network settings on the phone there is 3 options under Network Mode:
1. WCDMA only
2. GSM only
3.GSM / WCDMA auto
Now from what I've seen I need to use WCDMA to get the 3G / HSDPA to work, but when I select option 1. I don't get any signal and then phone eventually switches to GSM automatically. I was at work on the weekend helping a customer with her laptop and she had a 8•ta 3G modem, and 8•ta 3G modems are currently running off of MTN's network I was told this by an 8•ta technician and I noticed when connecting the modem it said something regarding WCDMA.
So now my question, if I change to MTN do you think I will be able to use 3G / HSDPA on my phone?
Any info regarding this will be greatly appreciated.
Thanks
The American version of the Aria uses different 3G frequencies (because that's what AT&T uses), so unfortunately your phone will not work with 3G in South Africa. There is a different version of the Aria (called Gratia in most regions) that is the exact same phone except it supports the correct 3G frequencies for your country, but there's nothing you can do with the phone you have now to make it work.
Hello All,
I am using A116, tried using t-mobile sim in US, device is not recognizing the network. It reads the sim as T-Mobile, noting else.
Can you please suggest if there is a way to fix this issue.
In the prefered network, there is a T-mobile ( GSM) network with id as 21901 and Priority 10
I tried configuring a new Network Id, its also not working.
Please help
Thanks in advance

T-mobile operates on 850 MHz band.. which is standard in USA whereas in India GSM bands are 900/1800 MHz.. A116 is made to operate on 900/1800 MHz band only.. it is a dual band GSM phone. You need a quad band phone which operates over 850/900/1700/1800 MHz only then you will be able to use it in India as well as USA
Hi,
There's a thread going on on the Vodafone UK forums about the Nexus 9 LTE not connecting to Vodafone UK on anything higher than 3G. I don't think this is very well known as the LTE version isn't as popular as the Wifi version, and then there are multiple mobile operators to choose from, so this might not affect many people.
Basically, a known working Vodafone 4G SIM in a known 4G coverage area will only establish 3G, never H, H+ or LTE/4G - this has been tested with multiple devices (I've got two here now) and multiple SIM's. The devices are unlocked, Vodafone don't require IMEI registration or anything like that. It should just be a case of putting the SIM's in. I've done all the checks I can think of (SIM's in another device - they get 4G, other operators SIM's in the device get 4G) etc.
Vodafone use LTE band 20 (and band 7 in a very few locations for LTE-A). Band 20 is known to work on the radios in the device because the same devices can connect to EE, who also use LTE band 20.
HTC are not interested as they say its a network problem, the device can register on EE and advised me to contact Vodafone.
Vodafone are saying its an unsupported device, I didn't buy it from them and don't really care, their first line support said the SIM is registering on their GSM network but never registers on the 4G network hence no coverage. After a conversation with second line support I was told that the device is trying to register on band 8 (900MHz) rather than band 20 (800MHz) which means that its a software/hardware problem - I'm a little bit dubious about this as how would they know unless it was negotiated by the SIM or something as their equipment uses 800MHz... ? I think he was basically lying to me to fob me off.
Google don't even have a way of contacting them about the device.
So as a consumer I'm stuck! Is there anyway I can debug the device myself? Can I see what bands are being used at different points in he SIM registering process with any software? Basically - any help or advice at all guys. It sucks to spend a load of cash on a device that half works, but what REALLY sucks is having no way to escalate a clear cut problem because there are so many companies involved!
Thanks in advance!
Hi, I m using this device (model XT1511) since 6 months but their is a problem. I can't connect 3G on this device. I select 3G service in setting and I am in 3G

What country and carrier?
I m at Pakistan n using UFONE 3G cellular service. I also received 3G capable Head set confirmation from cellular service provider.
I apply Phone information Android code #*#*4636*#*# but nothing happened.
Plz give me some useful idea.

The XT1511 is the US model. While it has quadband GSM, it only has the three HSPA bands that are used in the US (2, 4, 5). UFONE needs HSPA Band 1.
Hello !
My new phone plan is giving 100go data if you have a 4G phone (100go in 4G AND 3G). But if you have a 3G phone, only 3go data...!
I would like my phone to be detected as a 4G phone. It's a galaxy note 2 (N7100).
My mobile network operator uses the IMEI to detect my phone. Can I change it to a 4G phone like the N7105 ?
Any other idea ?
Thank you
I think you've been watching too much Youtube videos.
A bit mature reply: No you can't. Your carrier doesn't give you different network bands according to your IMEI. The network is always in the air. You just need the right hardware to pick it up. In this case your 3G device doesn't have the LTE modem needed to pick up the 4G signals.
