Hi All,
This thread is based on following closed thread for glaxy s5.
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
currently i am using T-Mobile s (g900-t) in Saudi Arabia. it only works with GSM network. so i followed the guide and enabled the 2100 band for 3G. now my phone is able to search for 3G networks but it doesn't get registered on the network.
To debug the problem, i connected my phone with qxdm and took the log while it was trying to connect to the network. it shows that every thing works fine until the network sends the "AUTHENTICATION AND CIPHERING MESSAGE" and when the phone sends the reply network rejects the reply. anybody have experience with the QXDM log or NV value editing might help.
i suspect that the T-mobile modem for s5 doesn't have the NV values required for connecting to 2100 band.

Hi all. I just bought a XT912 unable to get any 3G/data connection. I'm from Singapore and the bands are 2G-900/1800 and 3G-2100. I saw the specs on gsmarena stated that this phone supports 2100mhz band so I don't understand why I'm able to get any data connection. Ive set the mobile network to wcdma. Voice call is working well. Only problem is no data. Any inputs will be appreciated. Thanks!
Update
Problem solved. Added the user and pw in apn.
Did you set up any APN?
Hello. I have an SM-G925F which I bought from Telekom Macedonia and I am still using my number from there also but I am currently in the US and would like to use it on T-Mobile USA.
I know that the device supports all the same bands as the SM-G925T model.
The problem I am having is that when my phone is set to LTE/WCDMA/GSM in the Network Mode settings, I do not have any data connection at all, only when I make a call, I start to get a data connection but only 3G/H+. If I switch my setting to WCDMA/GSM, then I get a data connection at all times like normal but it still is only 3G/H+. I have tried two different APNs and different settings in the APN but I still cannot get a data connection at all times on the LTE/WCDMA/GSM setting and I cannot get LTE/4G at all.
After contacting T-Mobile, all they came up with is to try to have the same software reinstalled on my phone. Does anyone have any experience with this and can anyone help me?
Anyone?
Call Tmobile and have them input your phone's IMEI in their system. Ask for the APN settings as well. I am on the same boat and one call to ATT got me from H to 4G. Your phone will just show 4G, not LTE but you will get LTE speeds regardless.
I tried doing that too. I called T-Mobile a few times and they confirmed my IMEI number being on the account but still no luck. It's really weird..sometimes I get 3G/H+ on the "LTE/WCDMA/GSM (auto connect)" network mode setting on the phone but most of the time, I get NO DATA connection at all..only the signal bars.
Any Update
Did you finally figure it out? Is LTE working now?
Dear All,
I have purchased my s6 edge device a month before. Issue is this that whenever I try to use it with wcdma or LTE (auto connect) a message appears that "not registered on network" and phone works with gsm only. Means on gsm network mode phone is working fine but on LTE or WCDMA mode there is no network and emergency calls only appears. Please help in this matter. There is no issue from network carrier side its confirmed from them.
Hi am Haruna from Ghana.
I bought Alcatel Ideal 4060a (AT&T) model a couple of months ago, but problem is that the network doesn't change at all its always at 2g/EDGE no matter what i do or which network i put inside the phone.
Am currently using MTN (Scancom) which is a 4g Sim card and the phone is unlocked to any network.
And there is no option in the settings that you normally choose from your preferred network mode.
So i stated googling for the solution when i came across this code (*#*#4636#*#*) which i can use to change my preferred network, but whenever i change it, nothing happen, i mean nothing at all, all it does is that, when i select "only WCDMA" i will not get service/network, when i select "LTE only" no network, the only thing that work is GSM or WCDMA preferred.
So guys i urgently need your help as am getting frustrating by this phone.
E/GPRS is slow max u can get is 28KiBps, switch to 3g or 4g, it also depended on your att network coverage, Are you living inside bunker?
My H961N does not allow me to independently set my network band for each sim card. Both my network providers operate on 2G/3G/4G however since I have gotten this V10 I have had inconsistent network usage. At first I would strongly get one network and the other would mostly be on Emergency Calls when indoors depending on where I was. I used the hidden menu code *#546368#*961#-> Field Test -> Modem Settings, from Modem Settins I have tried to set the RAT Selection and the Network Mode however when I check Engineering Mode both sims show the same band if I am on WCDMA Only or GSM Only but neither provider operators on the same band except for one on 3G. If RAT is set to selectively move between two or more frequencies then one sim shows Invalid Band in Engineering Mode. Using Network Mode I have tried to set each sim to different band but both would either show the same band or one would appear invalid under Engineering Mode.
Another Issue I have is I am unable to use data even though I have the correct APN for both of my Network Providers. I have verified that both sims do work when used in another phone, at one point I visited both Providers but none could give me an answer to my issue. One of my Providers did however try and activated a data plan while I was in their office and the V10 did show 3G and received data however upon returning back to my regular surroundings I no longer got any data. I have tried upgrading the V10 to Marshmallow and Nougat but the upgrade did not solve this problem, neither the one I stated before. But on Nougat both my sims did show 3G but strangely only when I have my Wifi active and using a VPN. Currently I am on Lollipop and rooted I considered trying to flashing a qcn, sec and nvm files since I saw a site listing them as fixing network and data issues on this particular phone, I have the files just in case. Any help would be greatly appreciated.
