WiFi Tethering stopped working - T-mobile warning sign appears

Hi, I'm using AOIP 8/10/13 ROM on my Galaxy Exhibit T679 phone and Yesterday when I was using my laptop using my phone as WiFi hotspot, all of a sudden, T-mobile warning sign came up on a browser window and since then, any web page i'm try to connect ends up a T-mobile warning sign saying you have to buy a hotspot plan. Wifi Tethering has been working with no problem on this ROM till today, so I was wondering what happened. Can anybody give me any advice? I thought if I root my phone and use these custom rom, Wifi tethering would work even without having T-mobile hotspot plan or whatever. BTW, I've been using this ROMs build-in tethering feature and I didn't use any tethering app like FOX-Fi etc...Any help would be appreciated.

Just curious do you have an unlimited data plan.

it's a so called "Walmart Plan" which includes: 5GB data, 100 min talk time and unlimited text.
When I checked the usage of my data, it was like 300 MB, so I still have a lot of data left.

Hmmm idk what to tell you I have a unlimited plan and never had a pronlem with wifi tether. Maybe try wiping data and cache .

What browser are you using? I ran in to this before with same wall Mart plan. I found online about changing the user agent in the browser can get you around the T-Mobile page. I was using internet explorer. Go to developer options and then go change user agent to opera. See how that works.

If all else fails, its only 15 bucks more for the tethering with Tmobile.

[Q] WiFi Tethering & Calling issues!!

I'm trying to get wifi tethering to work but I've tried all kinds of ways and getting all kinds of issues. I did the freeze+ESFile Net approach, Wanam tetherprovision disabled approach, FoxFi w/ proxy (bluetooth tether does work though, however limited to web browsing with no youtube), and renaming the tetherprovisions apk+odex combination with all of these approaches to no avail. I either get FC or "no mobile data or invalid sim" whenever I activate the tether. It does go through occasionally to show the blue icon in notification bar saying tether is on however on my tablet or laptop I don't get any internet even if it connects to the phone (which after 30sec it crashes and doesn't reconnect). I am on Tmo's unlimited everything plan (which comes with 2.5gb tether capabilities) using my S4A(i537) AWS enabled and all. Don't know what is different with my phone and those that got it to work.
Also is there a way to enable WiFi calling on this phone?

I can't speak for the Wifi calling, but in this thread I talk about a good way to get tethering to work:

A few more steps then the freezing permissions, but it is much easier to use one you want to. (Also make sure to unfreeze the provision and make it like it started off before proceeding with those steps)

Best Wifi Tether WITH root option?

So I've been a longtime foxfi -> PDANet user and ever since 4.3 dropped I've lived without tether. It wasn't THAT big a deal for me since I tether in emergency situations only and they don't come up often but now that I'm on the S5 and root has dropped I realized it's time to get tethering as a backup working.
So my question is what's the current best wifi tether option for the S5 if you've rooted it? I don't mind paying for an app if there's no free version that does the same thing or just to support a good developer. I've found things like wifi tether:
https://code.google.com/p/android-wifi-tether/
but every one I've found seems old and hasn't been updated in quite a long time.
Any feedback much appreciated.

Grandfathered unlimited with no option to use the built-in Mobile Hotspot without giving up the unlimited. I use MAYBE 500MB-1GB tethering a month and I'm not willing to give up unlimited for the ability to tether those rares times especially since pulling into the parking lot of a starbucks has worked for those emergencies in the last few months.

That WiFi tether is OK to use. The core system has not been updated in a while, but if you look into the project a little deeper, you will find that the S4 just received it's own configuration into the tether.
With the S5 recently obtaining root, I'm sure the configuration will be patched in soon.
I am using 3.4pre1 (experimental). There are only two issues I came across.
1) The Logging portion fails.
2) If you are connected to a wifi hotspot, then start wifi tether, you will loose the configuration for that specific SSID. Don't worry, though, as a reboot will fix this.
Also, I use the S4 device profile. It seems there is somewhat smoother operations with this.

I have grandfathered unlimited data with AT&T and successfully enabled the built-in hotspot by using the "Disable tethering provisioning" option in WanamXposed

I just tried that and it didn't seem to work for me. I got impatient and just bought Wifi Tether Router 6 (that $25 google play credit makes it hard to be patient). It seems to work but I had some issues when I was connected to Wifi when I started to initiate the tether and actually if I was even in a place where I had a signal for a saved wifi. Forgetting the wifi networks in my house and it worked which I guess is ok since I wouldn't ever be using it someplace where I had another Wifi to connect to.
But I wouldn't mind figuring out how to use wanam xposed to do it, if there's a way to.

Yes it does seem to. Allows me to use native app, doesn't mess up wifi if connected already. I think I'll use this method. I'll just eat the $2.50 for wifi tether router I guess.

FoxFi (paid version) is working fine on my N4. So is the proxy add-on.
My only question is How do I hide the hot spot activity from TMo? I have the top plan which includes 5gb of tethering data.
How do I test this and fix if necessary?

When I said "working" I meant it's producing a wifi signal. I have no idea which part of the plan it's pulling data through.
That's why I asked how I test (hotspot or data plan) and fix it.

correction:
FoxFi is NOT working to divert data from hotspot to data plan.
Even using the proxy feature, it still shows up as tethering in the My Account app.
It seems all FoxFi does is turn on the Tmo hotspot app.

Updated thread: http://forum.xda-developers.com/showthread.php?t=2914057

So wifi won't work, but could anyone please verify that the Note 4 can at least be USB tethered to a PC with FoxFi and use T-Mobile mobile data, instead of tether data? I've searched all over and saw no one specifically verifying this with TMO, even though FoxFi generally says it's possible. I don't have a Note 4 or TMO yet to test myself, and prefer to stay unrooted so all the other options I've seen wouldn't fly. I'd probably barely go over 20GB in a month.
If USB tethering does properly hide it as mobile data, I wonder if it'd be possible to USB into a wifi router. I saw someone on Reddit doing that, but it wasn't a Note 4 and there was no specific hiding of tethering as it just used android's baked in tethering.
I've never used FoxFi before so if anyone could help with the following questions I'd appreciate it too:
1. If I have to use USB to PC, could I still use my phone for calls/texting/etc at the same time? Same question if FoxFi WiFi was eventually supported for N4?
2. While USB tethered to PC would my phone also be charging?
3. If I can USB into my PC, could I create WiFi from there in some way?
Thank you for any help!

Just coming back to update that yes you can use FoxFi to USB tether to your PC and have the internet useage be recognized as mobile data. Just need to put PDAnet on your PC. It does charge the phone at the same time, though extremely slow compared to fast charging. I've texted at the same time and used my phone in other ways as well.

[Guide] Enabling Full speed Hotspot / Tethering (Throttle Bypasses)

If your rooted then theres various ways to bypass and if used together chances are good you won't have to pay 2x for data: modifying your apn to allow dun type, adding the line: net.tethering.noprovisioning=true
to your build.prop and finally using adb from a PC (u can try this even if not rooted) type the following from cmd or powershell: "adb shell" followed by "settings put global tether_dun_required 0" without the " "s and restart your phone n hopefully that should do the trick.
If still throttled by TMo go into Magisk and install tethering_enabler or TTL tethering modules. These modules weren't specifically made for the 6T but they should still be effective. If still unsuccessful then modifying the TTL from the device your trying to tether to will help hide the source of data aim for TTL of 65 to confuse tmo.
If your not rooted then use PDANet USB tether to a PC and hide tether options then create a hotspot from the PC your USB tethered to or use the WiFi Sharing option in PDANet PC Menu. At least thats what works the best for me and I've tried many many things... One other possibility if your on stock no root is to add a new apn with all the same info as normal fast.tmobile.net lte apn only enable MVNO type to GIO for apn type leave it blank and save it. This should hide the default TMobile apn (and make the editor think your using a 3rd party like Mint) now go back and edit the new apn and under apn type put: dun,default,mms,supl try and save it. It should error n say dun not supported... Press Home and force close settings-reboot phone. The dun sometimes will stick if this method isn't patched yet I'm sure it will be soon.
Your final options are to use an app from playstore like VPN Hotspot or VPN Tether they might slow your speed a bit but they should tunnel all your data thru a VPN confusing TMo as to the origin of data. Probably the best and easiest way is by using a custom ROM as most haven't been tainted by Google's latest CarrierConfigManager commits or carrier apn restrictions. If anyone knows how to reverse these commits easily or any other methods not listed please let me know.
I'm currently looking for a clean TMo only dun enabled apns-config.xml so I can overwrite the default n modify the build.prop for a quick fix on any new ROM or update...
As you can probably tell being throttled or having to pay 2x for the same data is a pet peeve of mine and I've spent some time researching the topic. I'd love to hear what ended up working for you or if anyone knows a solid method I missed. Or has a recommendation for a good ROM with unlimited hotspot features built in for the 6t let me know. If any of these Bypasses helped you hit the thumbs up so I don't feel like I wasted hours of my life making this guide:laugh:

Right on what's the no cap no throttle unlimited run you a mo? I'm paying $25 for a one business plan it's unlimited but after 60gb they can slow u down and after 10gb of hotspot they throttle you to 200kbs lol but hey for $45 a mo they hooked me up with Netflix n my 6T lol still saving $15 from my old MetroPCs unlimited. But with the rooted bypass installed n the signal boosting hack I figured out I was at 430gb data and 217gb tether-hotspot last mo

I actually have the same plan. Didn't know it was discontinued until today for new signups. Kinda a bummer but I'll have to keep it in mind that I may not be able to get it back so easily. With that said they do sometimes send me the notification about the 50GB deprioritization/throttle but in my area I rarely ever see any kind of actual hit.

I thought you had to fix apn.xml

I can't figure out why but both my 1+3 and 1+6T have no limits on bandwidth out of the box. I can tether full speed and watch video with any resolution. I tried this unrooted, rooted, factory reset, even T-Mobile ROM. It was not like this a few months ago.

I tried this but it's become more than a quick xml mod as Google's forced various carrier check calls into their OS and it seems most aosp brands have incorporatated these checks blindly into their ROMs as well. If anyone's able to get a rom clean of carrier checks or knows of a kernel that will bypass these and willl keep a steady ttl of 64 plz post details. Otherwise the only success I had outside of pdanet tethering was to root and force a ttl with an app like ttl master yota 4.0 and running ttlpatch on your PC (Google those names for downloads) your kernel needs to accept iptables old versions if ne1 has a more upto date ttl modifying app that supports newer iptable changes (off the top of my head I forget what they are plz post) If I get around to it I'll try n write up a lil magisk module or app for easier forced ttl on Android 9+ ROMs but this or a faux VPN would be easiest way around any restrictions put on by carriers... Hope this helps a lil

I hook to PC with the USB tether and mods I tried to make run the hotspot off PC and it works i get 20-30mbs with data so hotspot I believe is the same I never had issues I'll start testing more if anyway I can help I will

most changes I make with a file manager resets every reboot so I used terminal to change everything so it doesn't revert T-Mobiles paid hotspot gets 5-15mbs on 6t with hotspot paid for I have 7pro I use to try this with so I know speed I need

You are aware that after 50gb you get reprioritized right? Even grandfathered plans get this, you might live on an area that is not too congested but once there is more people on T-Mobile on your area and you go over the 50gb you'll notice it.

they say that but I've used 100gb and had no issues I have the international one plan. but you're right on most people I have 8-9 lines digits is 9th don't count. the offline sim apn database pro app if you make a system app you can access the dun only apn they block.in xml they had hide apn enabled I changed that also.any other ideas if you need a crash test dummy I'm a good one lol

found the the file you was talking about and also I remember the carrier name on lock screen has to go also for you to fully unlock tether with pcweb apn

So far for the last few days I've been getting use of my hotspot without the data being reflected on the TMobile website as hotspot data. All data I use reflects as regular unlimited data. The issue I've run across so far is when traveling, it can revert back to original settings when changing towers, but only sometimes. At home on the same tower, no issues so far.
I did a couple of things to get unlimited hotspot. First I downloaded TTL Editor and set value on all interfaces to 65. Then I added a new APN with the settings in the screenshot. As soon as I saved it, all the regular TMobile APN's disappeared and only the one I added stayed. I have downloaded about 5gb of data through hotspot and so far no hotspot data showing up.
I have a TMobile OnePlus 6t on the TMobile network, converted to international. I hope this works for you. Please don't forget, changing towers SOMETIMES reverts back to old APN. I got back by rebooting and the APN I created showed up again. Also I don't know if everything I did is needed, I stopped when I realized hotspot data was being counted as regular data.
As far as speeds go, I get about 40 Mbs vs the 50-60 I normally get.
You must be rooted to do this.

I thought this thread was dead glad we are still working on this the database global tether_offload_disabled0 needs to be there I'm just trying to help and apn fast you have caps think that matters also maybe wrong there's a little more to do I think https://source.android.com/devices/tech/connect/tethering-offload

Using my mobile hotspot, so far I have binge watched on Hulu, and downloaded a bunch of things on various devices just to make sure I'm not missing something. So far, 4 days now, I have no hit to my mobile hotspot. The Caps was a typo, but since it's working, I left it. I don't know, all I can say is try it. I don't have any tethering mods, only the Magisk modules listed.

I'm guessing that something about the way the APN is entered causes all the hidden TMobile APN stuff to be muted. All the TMobile APN's disappear when this one is active.

Okay, out in town today and this APN method doesn't work in town. I had to revert to T-Mobile default to get reliable data. It only works great when I'm at home. I am rural and TMobile and AT&T share a tower here, maybe that has something to do with why it works at home, but not in town. So this might work for some people, but definitely not all.
