Hello!
I have a Mi5 32GB and I have many problems on it's data connection.
I use TIM BRASIL operator. It works normal normal on GSM 1800 and 4G LTE on B3 1800 and B7 2600.
If I set LTE preferred it works on 4G normal, good speeds, but NO CALL RECEIVING.
If I set 3G/WCDMA preferred it falls to 2G/EDGE, call received normal.
So, the phone never works on 3G. I think that it do not receive call on 4G because the fallback to 3G don't work, since there is no VoLTE on Brazil. Leaving it on 2G/EDGE is the only way to have data and receive calls.
I try all latest ROMS from MIUI 8 stable and developer, China or global. Also, swap SIM slots makes same result.
I try to replace my SIM card, and open a request with operator. No result. Put the SIM on other phone, like Redmi 2 Pro works normal on 4G, 3G, 2G and receive call on all modes.
I try to enable more bands using tutorial on https://forum.xda-developers.com/showpost.php?p=64675180&postcount=11 but no results, below is the NVRAM values original and modified:
ID Desc Original Value Modified Value
01877 rf_bc_config 562950035734915 562950069289863
00441 band_pref 0xFFFF 0xFFFF (Same)
00946 band_pref_16_31 0xBFFF 0xBFFF (Same)
02954 band_pref_32_63 131072 131072 (Same)
06828 lte_bc_config 2061584302149 2061719111903
I think the store that sold me this unit put it some kind of customization to not works on some bands. But I have made flash to stable and developer firmwares with no results.
I try other operator, VIVO BRASIL too. It works on 2G and 3G but not on 4G. Call receive normal.
If check the site http://willmyphonework.net/ see that Xiomi Mi 5 will work on TIM and VIVO normal.
Any sugestions? Please help me!

Good Day,
I purchased a network locked I9000 then used the SGS Unlock App in the Market to open my phone to any network provider.
The thing is, I cannot get 3G or HSDPA to work in my preferred network. I placed a prepaid sim from the Network I bought it from and 3G and HSDPA are working as designed.
Is there a possibility that the firmware I am using is still "locked" to some extent in terms of the frequency?
I have the correct APNs for both Network and I tried both sims to my old N97 and they both worked in terms of 3G signal.
BTW, I'm from the Philippines and I bought the phone from Globe Telecoms and my preferred network is Sun Cellular.
Here are the details of my SGS phone:
Model Number: GT-I9000
Firmware Version: 2.1-update1 (already updated it from KIES)
Baseband version: I9000DXJG4
Kernel Version: 2.6.29
[email protected] # 2
Build Number: ECLAIR.DXJG4
Other facts I can see in the settings (might be useful):
Signal Strength: -81 dBm 16 asu
Mobile network type: HSDPA
Service State: In Service
Mobile Network State: Disconnected
I'm thinking of re-flashing my phone to a different firmware but needed your inputs first. What firmware would work for me? Plus: would my phone get locked again to the original network if I re-flash it? Would the lock code change?
Note: here's some basic info about the two networks
Globe Telecoms
GSM 900MHz/1800 MHz
3G W-CDMS (UMTS)
3G Frequency 2100 MHz
Sun Cellular
GSM 1800 MHz
3.5G (HSDPA) 2100 MHz
Hoping someone can really help my dillema. I've been using Sun Cellular for 4 years now and I have no plans of changing networks even though their Customer Service stinks (no one can help me with this!)

P.S. I tried all the troubleshooting short of re-flashing. Multiple reboots, played around with the APNs, etc etc.
Also, my phone is rooted. Not sure you need that info but just in case
I forgot to add one last thing..
Yeah, I almost forgot. I can use my phone with my preferred network (Sun Cellular), to make & receive call and also SMS. It's the Internet Access that is giving me sleepless nights. I also called my network provider and I do have all the proper access in fact, I was able to surf using the same sim in my N97.
Additional Settings of my Phone (using *#0011#)
UMTS: HOME(CS)
RRC State: IDLE
WCDMA 2100 Band 1
Reg PLMN 515-5, IsPCS?0
FREQ DL: 10638
FREQ UL: 9688
Please help.
I bought and used a Korean version of Galaxy Note (LTE with DMB) on SKT network in Korea for a while. I liked it so much that I decided to use back home (USA) on my ATT 3G unlimited plan I keep for iPhone 3GS.
With ATT (a new micros sim) card, voice worked fine. But the internet speed is only 44 kbps with 'G' sign on the top notification area. I tried a lot of APN settings, reboots and hours of tech support form both ATT and SKT in Korea. No success so far.
SKT tech support said the phone carries neither country lock nor carrier lock, which seems to be true considering I can use voice on ATT without any problem. They insisted that I need to talk to ATT.
Using 'SGS Secrete Code' I tried to replace LTE B5 band originally set by SKT (?) with other LTE or WCDMA in the 'band selection', it won't allow it. Only 'Automatic' and 'GSM All' are possible to select.
My Phone info:
PDA : E160S.EK25.0152
PHONE : E160S.EK24.1917.ST
MOVINAND : EK25
BUILD : Fri Nov 25 01:58:03 KST 2011
I wonder if the hardware itself has limitation or it can be solved by some kind of setting or software approach. Please help.
My phone from Korea, SK Telecom, has the following spec.
Cellular+Phone
Cellular-Networks: GSM850, GSM900, GSM1800, GSM1900, UMTS850, UMTS1900, UMTS2100

Hi there.
I have the same phone. I have siwtched it to FA09 ROM, but I cannot switch on LTE mode as well.
Which SGS Secrete Code did you key in? and as far as i know, the LTE band in AT&T is different (not 2600Mhz)
I think you have to flash another modem to be able to switch frequency
I tried flashing the K model modem - but always giving fault through CWM
Hi,
I own sm-t715y, samsung website mention the availability of tdd lte band 40, i want to use a provider which is data only, it doesn't have any voice capability (called bolt). And a cdma provider which uses tdd lte band 40 as well (called smartfren).
Most of the tutorial on other devices which has tdd lte band 40 support has these steps:
1. Force lte only
2. Turn radio off and on
3. Set apn
I can't set force lte only on this tablet yet, tried *#0011# and *#2263# but it cant, the 2nd one cannot pop at all, please advice
When you say other device, this isn't Samsung is it.
I also have a S2 with band LTE 40, why don't you just buy a data only sim card, that is what I have 10GB data 1 year time limit.
Yes, the other device is oneplus one, alcatel one touch flash.
I tried experimenting with smartfren but no success at all, have not tried with the data only bolt, the cs said it cant but i doubt its true.
That is why, I had many Samsung, and non of them has lte only.
different phone/tablet has different features.
i flashed my phone with the global rom and now when i lock the screen while using LTE Network i can't recieve phone calls
only text message arrives on locked screen
when the screen is not locked or when the phone plugged in charger every thing works fine
P.S. on 3g network i don't have this problem​
I bought new mi5 and faced similar problem and ordered a replacement.
But the same problem persists in the new handset.
So after going through a lot of search
I conculded:
The phone network does not support voice over LTE yet in some networks.
Currently it is supported in europe and japan and some networks of states.
So no need to panic xiaomi is getting a patch to update to fix this bug from their side.
Till time enjoy callin/ internet via 3g network
By pressing *#*#4636#*#*
Select network to wcdma by which u wont have any problem of incoming calls and no net issues!
If u dnt bother incoming calls ..u knw how to get 4g?
Well you're doing better than me my phones never displayed 4g in areas I used to have it with my lg g5 any ideas using the *#*#4636#*#* apparently lte is enabled I'm on Vodafone UK also allegedly supported
Vodaphone and o2 will not work on 4G with this phone as it only uses band 20/800Mhz which is not activated.
4G Network:
1800MHZ
1900MHZ
2100MHZ
2300MHZ
2600MHZ

Hello.
I changed my motherboard recently to a MB I bought from AliExpress. MB is a WCDMA version. It works fine, but it does not register onto 3g networks. The same sim works in 3g in my other phone. When I search networks manually it shows awailable 3g networks. But when I select one it fails to register into a network. Please can someone help me with solving this issue.
Thank you
The model number says mi3w. Are there different varients of mi3w which doesn't support wcdma bands outside China?
My model says WCDMA. Are there different versions of WCDMA which do not work outside China?
