[Q] Urgent, Data not working, in any way.

I have tried dozens of solutions, NOTHING seems to work, I cannot get data, on any single ROM, and build any where, any how, I unrooted it, put stock firmware on, still nothing, I go to my mobile networks, and it says WCDMA preferred, I change it to LTE/GSM/CDMA, or any other option, I have no service at all, only emergency calls!! Then in about 2 minutes, it switches back to WDCMA prefered, I talked with Bell, for my i747m, they said nothing is wrong with my data! I have tried 2 different modems, still nothing, I have no friggen clue what is going on, it all started about a week ago, I just woke up with no data, if anyone knows anything, please let me know, I need data for work and school, this **** is killing me!

I didn't really do anything, I put my data on hold (Called bell and told them to do so) and now I took the data block off and now I can't receive anymore data, tried many ROMS, many APN settings, many modems , nothing.....
EDIT: Yes I called them 3 times and they confirmed that the data block has indeed been removed, all 3 said it would be instant, I took out my SIM car and everything.

Flash to stock, same as preparing for a warranty return. Verify you have an IMEI number. Replace your Sim card. If still no good, warranty return.

I might get a new SIM card, they are relatively cheap, I did flash to stock, everything brand new (for warranty return) I do have an IMEI number, I have been starting to lose signal every now and then, randomly, I just have no bars, outside, in rooms, at work, everywhere, and what's weird is that I lose all signal, when I turn on LTE/GSM/WCDMA

Have you checked to see if the IMEI is gone?

Unlocked, Rooted, No Data connection on Red Pocket att.mnvo

Greetings,
Purchased a T-mobile samsung galaxy s 4.
I unlocked it. Tried to use Red Pocket mnvo and there is voice but no data.
So I rooted it and removed the T-mobile data usage apk and still no data.
I have spent hours trying to get data to work.
What more needs to be done to get this phone to operate on a Red Pocket or Straight Talk mnvo using AT&T towers?
I use the same settings that work in my other unlocked android phones and no luck.
What APK is responsible for preventing data to work?
Do I need to flash a new customized rom to get this to work?
Has anyone else gotton an AT&T mnvo to work on this T-Mobile Samsung Galaxy S 4?
I am still within my return period so I need to find a solution or send this phone back.
I was orginally going to use T-mobile because they seem to promise 4g here but when I got it I find out there is only 2g speeds where I live.

My post won't help .. but this is very interesting as I am going to do the same thing.
I'll definitely watch this thread.

Is any one else out there getting Data connection with other carries after unlocking and rooting there T-Mobile Samsung galaxy s 4?
Any ideas on the cause of no data?

Try changing the network operator or the mobile network and see if your not using tmobiles instead of at&t...

You need to go to mobile settings and change the apn to the network you are trying to connect to also I think the phone has to be network unlocked

unlock isn't network unlock?

I did change the network to the one I am trying to connect to.
Also, I went to cellunlocker and got an unlock code. I thought that unlocks the network? The data has worked on all my previous samsung galaxy's after using the unlock code except for this phone.
Please HELP someone!

[Q] Enable Mobile Hotspot on Unlocked ATT Galaxy Note 2

We have a Galaxy Note 2 from ATT now. Just upgraded, so we're not using it. We want to take it to Europe to use as a phone and a hotspot for our computers on our trip. I've read that people do that with unlocked Androids and a European SIM.
I was able to unlock the phone with no problem using a data only T-Mobile SIM card in the process. The problem is that I can't turn the Mobile Hot Spot on. I've tried with the valid data only T-mobild SIM installed. When I try to turn the hotspot on, it says that either the network is not available, or there's an invalid SIM. I'm worried that it's the ATT restrictions on the phone that aren't going away even if the phone is unlocked, and there's a different SIM in place.
Does anyone know what we have to do to enable the hotspot, so that this phone can be used in Europe?
Thanks.

Try with wifix.apk

Thanks. That looks like a good app to fix problems connecting to external wifi sources. However, I want my phone to BE the wifi source when in Europe. Still looking for a solution.

The thing that sticks out to me is that you actually need the correct Sim card that is provisioned for phone service.. I'm assuming this "data only sim" was provisioned for a tablet and therefore can't make any calls... the network unavailable message will show up even with no Sim installed and trying to enable a hotspot. You need a valid cell service in order to hotspot.

Hope Getting the Right SIM will do it.

Thanks. I hope that's what the problem is. It would make things simpler to be sure. I just didn't want to get there and then find out it wasn't going to work. In the meantime, I found my old Galaxy S 3. I managed to unlock it, root it, and install basic ROM. Thought maybe that would work, as well. I'll know by next week.

Straight Talk data issues with custom roms using 4g LTE Verizon sim

Greetings everyone!
Signed up so that I can hopefully help someone else in need with their LG G3 phone using the Straight Talk 4G LTE Verizon sim card.
After many hours of flashing roms and trying out various things, it turns out for some reason other variants of the stock roms like Bliss Pop, CoudyG3, and Skydragon will not work with the data. I can still use my phone and make calls and i can still get text messages and even pictures sent through text messages, but for the life of me data would NOT work.
The only rom that did work again was the Jasmine rom. To my understanding it works pretty close to the stock verizon rom that comes with the LG G3. After the flash, BOOM! Everything worked and data came back to life.
I noticed the APN settings is very very different but this rom wont let you go in it to see it's settings. Surely there is a way to import/export the APN data to push on over to another custom rom? Just weird that after putting this specific custom rom data happily worked again.
BTW, if anyone tries to activate a verizon lg g3 with straight talk, be careful. Though their stupid website said that the phone was already registered with another tracfone provider/service, I was still able to get the phone to work. If after entering your MEID/EMI or whatever the numbers are and the straight talk website spits it back out at you, CALL straight talk. I got screwed and used up the network access code which somehow got lost into oblivion, but turns out that they themselves can manually add the Verizion 4G LTE sim card with the network access code card. (I bought the 4g LTE sim card package from wal mart). As long as the phone is in good standing, it will work!
Thanks. Hope this helps someone else out trying to get it to work with straight talk. I will try and see if there is a way to export this APN setting. I was told by straight talk that you don't need an APN set, but i think they are lying.
Peace!

solved
Back again,
Happy to report im using skydragon Rom with straight talk. Turns out you do in fact need to set the apn in the settings. Just add this apn
acct.tf.gw6.vzwentp
This is the apn for the Verizon 4g lte sim card when you use it. I didn't have to reset the phone but now data works great.

Hey question. I have a Straight Talk S3 currently running CM 11 kitkat based rom and things work great but I found other roms I want to install one of them being a Pac-Man custom rom but I have no data. I have a Verizon CDMA 4G LTE sim coming in acouple days just need the apn settings. Could anyone help me out with this? Thanx in advance for any help.

Surely it is the same APN setting as above. Try it out once you get your Sim card. Also, that S3 being a different phone may pick up on the access point names when you try another rom and set itself up, but if data is still not working, then try that APN I posted on the first post.
Also, be careful that you are actually connecting at LTE speeds as long as your area has it. Flashing to another rom I was only connecting at 3G. Turns out that once I tried another rom, you have to set the preferred network to LTE, then give the phone a reset. It took it a moment after reboot, but LTE finally showed up.
Depending on your phone, there are other settings to be set in it's hidden menu settings using the phones dialer. Just google around.
Hope this helps!

Note 10+ Factory Unlock Issue

Hi all, I'm new, so forgive me if this is in the wrong section.
I have two Note10+ I got from ATT both with clean IMEIs. I used a factory unlocking service where they send you the code to unlock the phone. The second phone I unlocked worked with no issues. The first one is what has problems. It unlocked however I had PIA VPN active when I unlocked it and it didn't shut down the same way as the other one.When I came back up, it now says Mobile network not available, gives me bars and then says emergency calls only, or flashes between the two.
Steps I've taken to troubleshoot:
Network and factory data resets multiple times
Changed the sim at T-Mobile, where it worked briefly but the boot up screen never changed from at​
The phone is clean on every IMEI checker I have used. I got it working once for about a minute after i went to T-Mobile (it worked and then stopped again). Both phones are from the same ATT account
Mainly I want it to find the signal and download the carrier settings so it doesn't have the fugly AT&T bloatware.
I suspect it may have glitched because the pia app prevented it from shutting down and running some process. Is there a way to force it to "re-unlock" so to speak? Or do I now have an expensive paperweight?
