[Q] After SIM Unlock, Tethering and Mobile Hotspot not Working - T-Mobile Samsung Galaxy Note II

Hi,
I bought a Samsung Note 2 from T-mobile last year with the tethering service (paid). The tethering and mobile hotspot worked fine.
Now, I am in Asia, and so I requested for a SIM unlock code from T-mobile, and it doesn't work; even T-mobile gave up and asked me to pay one of those unlock companies to unlock, and then T-mobile will reimburse.
After researching online, most unlock companies require to revert back to T-mobile factory Android 4.1.1 ROM.
Then, I did so. But rather than paying for someone to unlock for me, I followed the instruction of some online post to bring up the debug screen to run "network initialliz" (right, weird spelling).
I successfully unlocked my phone to use a local SIM card; then, I did the software upgrade through the "about device" screen to Android 4.1.2; but then I am not able to use tethering and mobile hotspot.
When I check tethering, it just unchecks itself without any error message on the screen.
When I slide to turn on mobile hotspot, it just slides back to "off".
I have done factory reset, and wiping cache from the recovery screen. Nothing works.
Then, I brought my phone to the carrier shop to check the APN settings, and it is correct because the sale guy had a Note 2 with the same setting and it worked for him.
Then, I took my SIM card to try on my sister's S3, and both tethering and mobile hotspot work.
Any idea how I can fix it without rooting?
I don't mind doing something more technical (as I worked as a software engineer for a phone manufacturer before...flashing hundreds of phones there).
If I post at the wrong place, I apologize; and please let me know where to post.
Thanks in advance.

I have similar experiences. I use an app like Hotspot Control or Portable Wi-Fi Hotspot to enable it while I am traveling.

Thanks for your confirmation.
Did you unlock your phone through the hidden debug menu? Or an unlock company? Or with the unlock code from T-mobile?
T-mobile said that the way I unlocked "might" not unlock "deep enough".

Anyone try foxfi wifi tether

On a unroofed phone?I'm on Verizon I have unlimited data and tether my s3 all the time. My fear is with this phone with a locked boot. And no root. Will apps like foxfi work? I know this is tmobile but Verizon is not out yet anybody test this I would love to know if you can wifi tether your tmobile phone without root. Thank you in advance for testing...
I have a couple of USB versions of tethering apps (ClockworkMod Tether and PdaNet) that I tested out on this device with 100% success. And I am not on the hot spot data plan. I personally only use it for times that I really need it (rarely). But I wanted to find out if it can be done through my current plan.
But SGH-T889, T-Mobile version of Samsung Galaxy Note 2, doesn't have its bootloader locked. Only the SIM usage on the device to be used other carriers is locked. But once we paid for the device outright, completing the contract, or cancel service & pay for the cancellation fee, T-Mobile will unlock the SIM usage on your device to use with other carriers. So yes, you can root SGH-T889, T-Mobile version of Samsung Galaxy Note 2, at anytime with no problem (as long as you follow instructions). Just that when there is an OTA update or Samsung Kies flash update we need to unroot it, stock ROM it, then take the OTA update or flash with Samsung Kies. Also if we need to get it repaired we need to reset the flash numbering too.
Bootloader locked is a different thing altogether. Despite that the bootloader is/will be locked in Verizion version of Note 2 I still believe that you can at least use the USB for tethering with ClockworkMod Tether that doesn't need a rooted device.
I do believe the community will find way/s around the bootloader being locked on Verizon's Note 2. But when is really the question.

I need the wifi tether without USB as I want to teher with iPad. Can you try this on your phone for me. App is called foxfi it's free

The WiFi tethering part I can't do that with this plan I have. Only through USB. If I went to their Hot Spot plan ($5 more) then yes I can. This is due to an app that they have running "Mobile HotSpot" (T-Mobile's own app). I believe if you freeze that app then, yes you can. I would also check with other ROMs for SGH-T889 (T-Mobile) Note 2 to see if the developer taken out or freeze that app. But this is due to that app and not because it is locked or unlocked. I really can't blame T-Mobile on this one. Unlimited data and WiFi tethering would easily get out of hand and cause the network to not function. Completely different from Verizon's tier system, where you paid for certain amount of data and you should, but don't, have whatever access to that data that you pay for.
Verizon has this fail safe with tethering usage on their end of LTE network. This is why people get warnings and kicked off from Verizon Wireless. Now Verizon has the tier system and charge per device on their network that both help in curving this issue. Again this due to the fail safe that Verizon put into their LTE network.
FoxFi doesn't support Jelly Bean.

On T-Mobile, if you freeze/uninstall the app Tethering Provision, you can use the wifi-hotspot with some caveats. 1, You can't start the app directly(It will crash). You can download a wifi widget from the market that will start the app no problems. 2, T-mobile current scans Http traffic for user agents. So if you use a desktop browser you'll get your traffic blocked. There are a couple of ways around this. Https works fine because it's encrypted. You can change your User agent to any non destop browser and it works fine. I found that xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx or similar garbage works best because it doesn't cause sites to show up as mobile and T-Mobile wont block it. Or you can use Tor or anything else that will encrypt your traffic.
But seeing as you want to tether to your Ipad, It should work perfectly with no issues as of **NOW**
My foxfi works. I cant explain why. I am stock with root, and unlocked. My hotspot app comes up asking me to configure it, I simply ignore it and continue using foxfi.

That make me wonder: does anyone know of a carrier that sells "prepaid" or "metered" SIM with data plan? I will remove Verizon's SIM and stick it in instead only when I need wifi hospot. It should be cheaper than paying $30/month for the service or switching to Verizon's "Share Everything" from my current unlimited.

I treid foxfi on my rooted sgh-t889 with stock OS. It appears to work (tried using other tether apps like wifi tether, turns on but didn't broadcast SSID) but to be quite honest i cant verify because i haven't enabled data on my plan yet!
Im prepaid so I'm waiting for then ext cycle before i can really be sure, but like i said and others apparently too, foxfi seems to be functional for what its worth on sgh-t889
I tried Foxfi today on my tzones plan using a AT&T Note 2 with T-mobile Service (unlocked the aws band), it seems to work fine.
Anyone use this app longterm on T-mobile and with T-zones?

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.

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

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.

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.

i had a similar problem. after a software update was applied automatically, I lost wifi calling b/c my inserted SIM is not tmobile despite the device being unlocked. So, I inserted a tmobile sim and used ODIN to flash the latest stock firmware, and then i got wifi calling back. I'd test it first with a Tmobile sim (i bought one off ebay) and then restart the device. If that doesn't fix it, you may have to reflash stock firmware like I did.

I have a T-Mobile SIM installed right now, I've shut it off and restarted numerous times. I've never used ODIN nor flashed firmware. Where would I get the correct software to do this? Also, would it make a difference if my phone is an international dual SIM?

I had a similar problem and couldn't even find the wi-fi calling option, let alone enable it. Here's how I fixed it: I enabled Bixby and updated it. Then I said "Hey Bixby, enable wi-fi calling..." and not only did Bixby enable it, she located the settings. The setting lives under "Call Settings" which isn't accessible in any other way than by using Bixby (at least from what I can see).
Now wi-fi calling is enabled and I now have a whole host of additional call settings available to me.
Hope this helps.

Enabling Cricket Wifi calling on 960u1

Hi,
I am trying to get the wifi calling option to appear and work on my 960U1. Here is what I've done so far.
1. Utilized Odin 3.12.3 (not patched version that I've seen on some forum posts) to flash AIO firmware G960U1UEU1ARBG (which i'm pretty sure is the only cricket CSC from updato.com, Sammobile has nothing listed for AIO )
2. During flash I made sure to select the CSC (not HOME CSC)
3. The flash looks like it was successful and the phone was automatically factory reset.
3. I am still missing the wifi calling option (i checked both settings-> connection menus, and the Dialer. I also tried making a call in airplane mode with wifi and it said i needed to turn on cellular.
Does anyone have any ideas what I need to do? Only thing I can think of is I'm missing a firmware or I need to change how I'm flashing the phone.
Here is a link to the cricket website saying wifi calling is supported on the S9 https://www.cricketwireless.com/sup.../wifi-calling/customer/compatible-phones.html
Thank you
Update:
So I was realized what I was missing was the AIO (Cricket) User Data. Once I located that and flashed it along with the Firmware using Odin I know have the Wifi-Calling button added to my phone. Now when I attempt to turn it on wifi-calling I get the "Please try again later" message.
I contacted Cricket Wireless Chat support, told them I have a S9 with cricket Firmware and they asked me to provide the IMEI, when I provided the IMEI they stated that it was for an unbranded S9 and that I would be unable to get wifi-calling to work on their network because of that.
Does anyone have any ideas on how I could get them to authorize my phone to get access?
It is not going to work no matter what. You have to be using an iPhone or their Cricket Branded Android phones.... -_-

Even if Crickett wanted to, their agreement with AT&T would probably prevent it. Even AT&T requires an iPhone or one of their branded phones for wifi calling. You can give up this fight.

If you had another Cricket branded Android that is wifi calling capable you could have them hard set that IMEI in the system, and that should get your S9 working.

Thank you,
I've considered this option, but now I'm weighing another consideration. It looks like mobile hotspot is disabled on the cricket firmware with user data. So unless I pay for the service maybe i should stay on a generic firmware so that it will give me mobile hotspot vs wifi calling...
\Again, FYI and maybee everyone already knows this.
The idea behind the "unlocked" handset and Android was that each carrier would have its own app to use for these handsets to enable these IMS features. As usual, the wireless US carriers have perverted the concept to tell then end user to f*ck off because you did not pay a premium for the carrier branded/bloated handset.
Man....MINT SIM is looking good.
Just FYI, Wi-Fi Calling will work fine on U1 flashed to Cricket's firmware. You just need to provision your SIM card for Wi-Fi Calling, to do that you need to insert your SIM into iPhone (SE or 6/7/8/x) and activate Wi-Fi Calling on that phone and test it out, once you see it active - remove SIM card and put it back to your S9. After you put the SIM back into your S9 - do a network settings reset, after that the Wi-Fi Calling should work. This is how I made my S9 work. If you don't have anyone to borrow iPhone from - go to your local Apple store, buy one then return it next day

I've been attempting to get this working on my ATT (carrier unlocked) S10+, but since Cricket only supports the S10 (not +) I'm unable to find an appropriate userdata. Do I have any options?
Wifi calling will work on non cricket device under one condition. You activate wifi calling on a cricket device. With your sim in it. Then put the sim in your phone. I also flash any multi csc firmware. And place cricket sim in the device so it auto personalizes. so then you have cricket firmware so to speak. I'm using a g950u xfinity right now on cricket with bit 7 even though cricket has only bit 6 out. And he calling and wifi calling work great
