Mobile data won't connect at all - T-Mobile Samsung Galaxy S6

My gf's phone won't connect to the network at all, the only way she can use her phone is if she is connected to wifi.
Here are the things I've checked so far
Bill has been paid
Restarted the phone
Double checked Airplane mode
Ensured there is not a data cap on the plan
Ensured there is not a data cap set on the phone
Double checked APN settings are set to t-mobile
Removed SIM card for 5 minutes and then rebooted
The phone has not been flashed nor rooted, it is stock.
What happens when she disables Wifi a message comes up 'Can't connect to network, please try again'
Not really sure what to do at this point, any ideas or things to try?

Loss to GSM Network

I have a TyTNII phone and after reading extensively through the threads posted, seems to have a unique problem.
My device will show the "E" icon and service provider in the Today screen and everything will be normal.
After connecting to the Active Sync via USB the phone will be normal for a while, but at some stage will disconnect from the GSM network and show no service.
At this stage the "E" icon changed to a "G". I have tried selecting the service provider, finding the network etc, but it keeps telling me to disconnect the data service and try again.
At first I thought it was blue tooth, but it does make no difference. I have loaded all the comm utils I could find and none is showing any active data sessions or connections.
Reset does not work, taking the SIM out and putting it back does not work, not even taking the battery out makes a difference.
All that seems to work is to put the SIM back in another phone and let the phone boot up to get GSM connection. After that I can put the SIM back in the TyTNII and all will be fine - even for days - as long as I do not connect USB to the PC.
Do you have any ideas on what I can do to solve the matter - it is irretating like hell to swap a sim every now and then...
could be wrong but is there a wired connection on your pc/laptop that uses a dial out and not gprs, this could cause it to run a connection on gsm on gprs.
Thank you for the reply - I have checked my pc and have no dialup connections - currently connected to Internet via Ethernet.
I have also checked the phone - during this shutdown period I am able to browse the internet from the phone.
This tells me that I have internet access, just no GSM service - its like the phone is switching the GSM network off, but GPRS and Edge is still working.
Hope that helps
Dunno where you are geographically, but At&t had some major down time last friday or thursday and it seemed again this week on tuesday or so.
Maybe this was effecting you? (boston area) Only time my kaiser does **** like that is when i leave something conflicting open, (mail, or a browser)
good luck

[Q] 3g will no longer connect

I installed CM6 onto my sister's Hero as well as my mom's Hero. My Mom's Hero works fine but my sister's will not connect to the 3g network! I have gone through and turned on/off all of the network settings and can't get it to re-enable the data services. Wifi works, calls/text work, just not the internet connection over the mobile network. I tried flashing Fresh to see if that would work and I get "Data Call Failure - Error Code 67 .Registration failure. Your PCS Vision username and/or password may be incorrect. Please try again." repeatedly. The 'Mobile Network' in the settings menu in Fresh stays stuck on "Turning on...". I don't get that error in CM6, however. I've tried reflashing/wiping as well with no luck. Is the 3g radio separate from the radio that does calls/texts? Is there a way to check it? I don't want to tell her that I broke her internet connection :/
What radio are u using on that phone? And what all have u wiped?
Root-Hack-Mod-Always™
I was using the most recent radio I believe, 2.42.01.04.27, and I tried wiped everything in recovery. I continued searching for an answer and was able to find a thread that solved my problem! http://androidforums.com/sprint-her.../13197-data-call-failure-error-code-67-a.html
I just had to go into system updates in about phone and perform a 'profile update'
When I first setup her phone she couldn't remember her gmail password so we reset it and she was able to log in. I completely forgot but her 3g worked for that day! the NEXT day we noticed it wasn't working and it stayed like that for a few days until I was able to fix it now. She set up her gmail account at the sprint store when she first got her phone, could her gmail password somehow be related to her PCS username/password so that changing it screwed up her ability to login into the sprint PCS service? I'm still confused as to why this happened on her's but not on my Mom's phone, and never on my phone!
I had this happen saturday night,, running dd 2.8.. data would not start for nothing.. I nandroided back.. and all is good!!

[Q] Mobile Network - Connection Failed

I turned my Mobile Network (3g data) connection off for the night to conserve battery, and the next morning when I tried to connect again via the quick settings, it didn't connect.
Under settings it has the caption, "Connection Failed".
The network was working fine for ages prior to this, and on a few occasions, turning off Mobile Network for the night was fine.
I've tried resetting the phone and taking out the battery + SIM for a few minutes.
I've also tried re-entering APN settings with no luck.
I'm with Vodafone Australia, running the stock 2.3.3 virgin au rom.
Nobody else on vodafone is failing (relatively speaking )

Update:
It was a 3G widget messing everything up, thanks letmedanz
Any ideas?

Did you try wifi connection?
just wondering..
i am quite certain your problem is with the apn settings.
try deleting the existent apn and enter a new one. save it and try reconnecting...
though not very important, you could check for the port number to enter in the apn settings with vodafone.
also, if you are using any third party apn modification tools or even a simple 3G on-off widget, the settings do get wasted.
if you do, uninstall them, re-enter apn settings and try

(Rooted)Phone not auto registering when entering new network area

When I drive to work my phone at some point drops connection to tmobile network then goes to searching and stays there until I turn airplane mode on and off, then it will reconnect to network. It's annoying to have to do the airplane mode thing to get it to reconnect to the network. I have checked the network settings and its set to auto connect or auto register, so I am not sure what the problem is. Anyone have this issue? I am sorta new to root and I am pretty sure I didnt unistall anything necessary, just normal bloatware..
Nevermind, called customer service, eventually got someone techinically savy, I got a bad sim card that wont switch towers automatically. Going to the store to pick up new sim after work.

Not being able to use mobile data whilst roaming is on/ can't turn roaming off

I have got a xiaomi mi 5.
I have gone to a different country for two weeks and bought a sim to use abroad. For the first few days everything worked fine, but all of a sudden the r symbol came on at the top (I believe it means roaming) and I am unable to use my mobile data. When trying to test my connection it says I must turn roaming off to use mobile data.
The problem is I have turned integration roaming on and off and nothing has changed. I've turned my phone on and off, restored it to factory settings, let it run completely out of battery and nothing has worked as of yet.
Has anyone got any ideas of what I can do?
