[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.

How to use AT&T VOLTE and WiFi Calling?

Hi everyone, I'm on an unlocked/rooted/xposed G928T on AT&T, and I'm wondering if it's possible to enable those features through my AT&T SIM. When I enable WiFi Calling in settings, it simply pops up an "invalid SIM" error as I'm not a T-Mobile customer.
Furthermore, even though I have the proper APN set up and AT&T has an iPhone 6+ IMEI in the system for my SIM (so VOLTE is set up on their end), I can't seem to get VOLTE to work either.
Any ideas? Perhaps I need a system dump of the AT&T version to piece it all together?
Thanks in advance!

First is to make sure you have a UICC-G sim. The 9th and 10th digits of a VoLTE-capable UICC-G SIM card will be either 27 or 28.

@cblackledge Thanks for the reply, however I used this SIM in my iPhone 6 Plus and VOLTE functioned without problems.
No such luck here, however :/

@SolarTrans did you go into to phone setting and cut it on

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

Where did you find the User Data file? I've been looking high and low and just can't find any. Thanks

Also would like to know where you got the UserData.

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

No data during call after oreo update

Hello. I'm hoping that someone can help me out. I have a Verizon note 8 that i use on straight talk for the longest it never would update to oreo but then i cracked the screen and purchased another used verizon note 8 from ebay. It came to me with a cricket sim card in it. I turned it on and connected it to wifi just to check it out before i transferred anything and it immediately wanted to update so i let it and it updated to oreo. I swapped over my ST sim into the new phone and stuck the cricket sim into the old phone and it updated too. But now my problem is that I keep getting the message that data is unavailable during calls. When i check the settings it says i am on CDMA/EVEDO/GSM/WCDMA. And there is no option to edit my APN. If i click on the mobile network i have the option for LTE/3G/2G but if i choose this nothing works and i have no option to go back to the CDMA/EVEDO/GSM/WCDMA and thus have to do a factory reset. I have tried texting APN to 611611 but it states my APN is already setup. I called tech support for ST and they told me to call back from another phone which i cant do until this evening when i get off work. So i thought in the mean time i would reach out to the real pro's on here and see if anyone else has had this issue. Did i mess up by updating with the cricket SIM inserted? Or could it be that i just didnt call straight talk when i swapped phones? i just took the sim card out of one phone and stuck it in the other. I really appreciate any advice anyone may have. Oh and I've tried finding the settings for HD calling to enable them, not there.
Thanks,
Amy

I'm having this same issue with my Verizon branded note 8 that I manually updated to Oreo. I called my carried, Red Pocket and they stated that this is enabled for my account. In Oreo the hidden menus seem to be disabled and I've tried other things. I may have to see if I can go back to Nougat. The dialer hidden menu I tried was *#2683662#. On the Verizon forums, other were able to get to the menu using *#4636# and enable VoLTE but that seems to be disabled for me. I tested from my coworkers note 8 and it seems to work fine on their phone.

I reflashed CRID and the CSC but my Service Provider SW ver. still says VZW/XAA/VZW. Does anyone know how to fix this?

Has anyone figured this out? I am having this very issue and Straight Talk has no clue what I am talking about.

I found this on the Samsung website and it looks promising but nothing has changed. I was able to see that the radiobutton/checkbox for LTE Enhanced is checked.
To enable HD Calling, download Shortcut Master (Secret Codes) Lite from developer vndnguyen. You will need to find the apk as it does not appear to be in the play store any longer.
1) From the option menu located in the upper right hand corner, choose Search.
2) There is a search field at the bottom of the screen. Type lte then hit the Search key.
3) Scroll down to Mobile Networks. Choose the one that show EnhancedLteServices. Then click Launch. Then click the box to enable HD Calling.
I was also able to set the APN settings to Bearer: unspecified using Shortcut Master lite but this made no difference whatsoever.
Finally, you don't need to do a factory reset each time you go from CDMA/EVEDO/GSM/WCDMA to LTE/3G/2G (auto connect), simply search in settings for reset network and then reset the network settings and reboot.

I was able to get the SIM card trick to work for me on my Note 8 as well. I have redpocket and prior to doing the sim card trick I did not have VoLTE. Now I do. It's too bad that this is majorly inconvenient and it won't stick after a reboot, by the sounds of it. I haven't tried yet. I may just tape the sim to the back of my phone or inside my case. Also, on my Note 8 prior to this, I was seeing vzw/xaa/vzw and now it has the vzw/vzw/vzw CSC with the RP sim in. I'm hoping that there is another way to fix this but at least I have a work around.

I updated to Oreo on my verizon note 8.
I dont have any options for advanced HD Calling, Wifi calling.
When I go to ims settings it says denied.
Any ideas

Wifi Calling, Verizon Pixel 2XL, using Straight Talk AT&T Sim no option

Hey all, I've been pouring over the forums here and other places trying to find a solution to my issue. I just got a Pixel 2XL the verizon version and I'm using it on Straight Talk with an AT&T sim card. So far so good except I cannot get wifi calling. I'm pure stock, android 9/Pie, no bootloader unlocks/rooting etc. The wifi calling option does not exist in the phone app nor in the settings anywhere. Even when you search for wifi calling, it simply takes you to the network and connections section of settings but wifi calling is no where to be found. I've tried the adb command (the one that apparently used to work on Oreo but not longer does on Pie) and that didn't work (though I didn't expect it to since many people said it no longer works on Pie). I have an Unlocked Note 9 as well and its wifi calling works perfectly fine so does anyone have a way to make this work? Reception at my home is somewhat lacking and I really need wifi calling.
Thanks!

Could you attach a screenshot with the WHOLE section of "Mobile Network", found inside of "Network & Internet" in the Settings -- make sure that you click on the drop down menu next to "Advanced Calling" -- this will help make sure that wifi calling is really missing as well as might point something out that may help with a solution. Moreso, personally, because I can't even imagine what the settings menu looks like missing this...

It might be a long shot but try checking the settings in the Google phone app. There should be a place that says configure IMS calling. I have this setting here and in the network settings. If you have it that's where you can enable wifi calling.

Been there done that. I have no options for setting up IMS calling. I only have SIP options. Also, I have tried the phone dialer trick (where you dial *#*#4636#*#*) and that shows the wifi calling option as a toggle but its greyed out and cannot be enabled. I even tried an adb trick that used to work on the 1st gen pixels, but to no avail.

What happens when you enter your information here?
I'll have to initiate a chat with Straight Talk. Like you I have a Pixel 2 XL with a Straight Talk AT&T SIM. The only difference is that mine is unlocked. I just ran my phone number and the IMEI of the SIM through the linked site and it tells me my device is not compatible. Since I have a BYOP SIM and the IMEI is of the SIM itself, chances are high that the SIM needs replacing with one that includes WiFi calling support.
EDIT: According to the representative I just spoke with, there's no guarantee that changing to a newer AT&T SIM will enable the feature. The only guaranteed method according to tech support is switching to a T-Mobile SIM.

Hey thanks for the help. I tried that link as well (before I posted here; sorry I should have mentioned it) and it said my device is also not compatible. I initiated a chat with them and they told me the same; switch to T-Mobile. I am tempted to do so but the one thing holding me back is my home is already a place I get poor signal and T-mobile's coverage while much improved still isn't as good at AT&T's. I realize that having wifi calling would fix any lingering signal issues but I do manage to get 1-2 bars of 3G at my house with AT&T, I figure I won't even get that with T-Mobile. So I am weary of the switch. I'll have to consider it though. I could also wait for the full rollout of the latest google voice (since it finally is bring VOIP without the need of hangouts) and just use that number instead.

So I contacted Straight Talk and ordered a T-Mobile sim card. It'll be here in a few days. I will post my findings after it arrives. Straight talk support says wifi calling works with all T-Mobile sim cards so we will see.

Hello all,
Okay, so I finally got switched over to a T-Mobile sim card (again still with straight talk). It took a while cause I had to buy a new one (the old one I had expired; who'd have thought?). Anyways, switching to T-Mobile solved all my problems and then some. Not only do I have Wifi calling, but also HD voice, VOLTE, Tethering, and 3-4 bars of LTE (previously on AT&T, I got 1-2 bars of 3G). I realize the signal issues is merely a coverage thing but I can say with certainty that switching to a T-Mobile sim card will give you all the advanced features. I hope this helps others who might experience this problem. I've been using AT&T (in one form or another) for the better part of a decade and can now honestly say, AT&T sucks.
