Okay so I have this tablet and it was originally on T-Mobile. I unlocked it to use it on WIND MOBILE here in Canada because both these companies use AWS. The tablet does connect to WIND network but I cannot browse or open anything. Infact, there is no 3G icon either. I have tried everything - from flashing factory ROM via ODIN to turning off all wireless and ON and rebooting....I just cannot get 3G to connect. The APN settings are also correct. What else can I do?

I guess you are referring data connection to 3G network? What about data to 2G or EDGE network? SMS is working fine? Also verify IMEI no. whether its corrupted or not?

My father is using Tab2 (P3100). Running Stock OS, Unrooted. 3G Data Connection from Vodafone Delhi India.
since a month or so back he found a update notice and upgraded the Stock Firmware to Latest 4.1.2 using WIFI
Not sure but might be since then, Whenever he's On Roaming, Data Connection Won't work.
Currently He's in U.P. circle it won't connect, Voda has 3G Service here, And I use it everyday at home/city wide.
Tried following:-
1). Checked APN Settings, they are correct.
2). Checked Data Roaming in Mobile Networks.
3). Tried Switching to GSM Only, and WDMA Only, WCDMA/GSM Auto Option, All options same result.
4). Checked wifi is OFF, and Data Connection IS Enabled, using Widgets or APPS but it won't turn on
5). Took out the SIM from Tab2, and Inserted In my Android Phone and 3G/2G Connects Instantly.
6). Put A different SIM which is from my Region but as its not On Roaming, Data Works fine.
7). Checked with operator they have no clue whats wrong in the TAB.
8). Requested Fresh APN Settings from Operator and saved it, But Tab2 won't connect.
Can someone shed some light if this is a BUG in current latest firmware of Tab2 or I am getting and my brain fails to finds a solution.
Any help will be appreciated, don't let me down my fellow members pleaseeeeee

Do you need to set your APN up correctly for your network provider?
I know I had to do that for a MVNO I use here in Australia recently on my N5.
I found the problem (in my case) I had to reduce the preferred data protocol to 3g instead of LTE. Everytime my tablet got LTE connection it lost it's connection... Airplane modus on and off, and then reconnect... 5 min later.. bang... After I tuned it down to 3G this stopped...
Hi, I recently bought a LG g3 smarthphone and I found out that it's an AT&T version phone, but thankfully it's unlocked. My problem is, that it doesn't get any mobile network. In the setting it says that the Mobile network type this device can use is HSPA, my local carriers can only provide LTE, GSM and WCDMA rat types, I don't know if it's the case. I've tried to solve this on my own, but without luck. The solutions with 3845#*850# or similar codes just woun't work, when I choose any RAT it says: "succsess", but it doesn't change a thing and when I choose "LTE only mode", the phone blocks my mobile connection and says: "Restricted access changed: Data service is blocked" .
I really need any help, because I cannot see myself using a mobile phone without mobile internet. I tried to use 2G, 3G and 4G networks, but none work, nothing appears. Also I tried to fix this problem by flashing a Cloudy ROM wich is lollipop 5.0 and it didn't solve my internet problem. BTW, my location is Estonia.
I really need your help guys, I'm desperate as hell, this is my last option, because I didn't find any other solutions on my own.
Counting on you :3

I think your a little confused about your network. HSPA IS WCDMA/GSM. You want to just slept gsm/WCDMA/LTE

Flashing a ROM is not the solution. AT&T version of the LG G3 covers a limited radio frequency spectrum. It could be that the phone does not cover the frequency of your carrier. Another issue may be with the carrier themselves blocking the IMEI (I know some carriers require registering the IMEI on their network). Of course you must also make sure the carrier has data services available to you.
I kinda have the same problem....
No service.
I've tried everything to no avail.
Help gor a fix.
I'm customer of the local carrier "Drei" (Hutchison) but my Pixel (bought in Germany) does not connect to the 4G / LTE network.
The support of Drei is not able to help me. LTE is working fine with the same SIM on the OnePlus One.
Any clue how to fix that?
There is regional problem I came across. In India here we dont have VOLTE support on pixel

What LTE bands do they use on Drei?
Same happen to me in Portugal with MEO. I can't seem to solve it. Talked with my carrier support, they don't know why I don't have 4G/LTE.
I never got 4G, but my SIMCard has no issues with iPhone getting 4G right away.
Is it Pixel issue? I start to think it is..
3/Drei is listed here: https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe#Commercial_deployments
The specs of the Pixel are listed here: https://madeby.google.com/phone/specs/
That is all information I have got.
Is there any possibility to display information about nearby LTE senders via an app?
After activating "LTE only" via *#*#4636#*#* it works. Everytime I search for networks or reboot my phone it still connects via 3G and switches back to "LTE UMTS auto (PRL)".
Seems to be a software issue.

I use the phone on Verizon and don't have any problems connecting to LTE using any available mode (Global, LTE/CDMA or LTE/GSM/UMTS). However, if I set the mode to LTE-only via the menu, it will also reset when I either reboot the phone or if I just open the "Cellular networks" menu. I think it's how it supposed to work because that menu doesn't have the LTE-only option, so it resets the mode to whatever you see there. The solution is simple - if you reboot the phone change the mode again and don't go to the "Cellular networks" menu
Regarding why it doesn't work with "LTE UMTS auto (PRL)", it might be because Drei didn't configure a handover from UMTS to LTE on the cell site you're connected to. It looks like Pixel finds UMTS signal first, but doesn't know that LTE signal exists due to a missing handover. Another phone might be fine if it searches for LTE signal first. But if you can see another phone switching from UMTS to LTE in the same spot, my theory is wrong.
Hi all,
I was using my P905 international version with LTE before my EU trip.
In EU, I lost the 4G connection in roaming. When i came back to home country, i found out LTE is not working, when i attempt to make a call, i get not registered network message and lose connection.
But I have phone function and EDGE internet in GSM only mode.
IMEI number is correct, and it is same as original.
Try to solve problem, I made factory reset more than 10 times. I installed Hong Kong, Taiwan region roms Kitkat and Lollipop, even Lineage os from here. But no luck, no LTE anymore.
When i play around with *0011# and Q > 0000>UE Settings & info > setting>Protocol>
I receive 4G connection for a while then I lose it again.
I tried Auto/Manual Network Choose too, nothing works but GSM only.
I checked EFS files, everything seems correct, no corrupted file there as I understand.
Do you guys have any idea how to solve LTE connection problem?
I think i found a solution. Not sure.
I download the CP / MODEM file from following link.
https://zfirmware.com/samsung-galaxy-note-pro-12-2-p905-repair-firmware/
I made hard reset from the system. I delete user files and reinstall it.
4G and 3G came back. Now it is connecting to 4G and can make phone calls. But the connection drops after 10 mins. I need to turn off mobile connection and reconnect it. It connects for few minutes or never.
I need to restart the device and getting 4G or 3G connection for a while again.
When it connects to 4G or 3G, if it is stable connection, I can make phone call too and does not receive not registered on network error.
Should I install Stock Rom again? or try to play with some config files?
Do you have any idea?
no idea?
is there anyone has nv_data files in EFS folder? I think mine is missing.
Hi, I have the same problem.

did you try to do anything?
we need help here. Is there anyone can help us?
I do not want to give up with my P905.
no help?
do you have any idea to have stable 4G? Only LTE mode is not stable. I tried. Now GSM/WCDMA/LTE mode is running but, LTE is dropping very often. I get stable connection with other Samsung Device.
as i see, there is no help. I am changing to T835 256gb LTE version.
