[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 Activate HD calling on T Mobile?

I have Just updated my phone to marshmallow hoping to get wi-fi calling but it still asks to activate advanced calling.
Is there any chance that i can bypass this to get wi-fi calling?
Also in case if i ask my friend to activate it using his SIM and later insert my T mobile sim will i still be able to use it?
Thanks in advance

Some people here have had to get Verizon to set HD calling up for them, especially if they've had it turned off. T-Mobile may be the same way.
If I recall, Verizon users were able to turn the feature on online.

Then I'm afraid you're stuck. It looks like HD calling is a prerequisite for wifi calling. Both, while sharing the same technical standards, are run by the carriers.

Verizon Advanced/HD Calling on Unlocked S9+

I currently have an Unlocked Galaxy S9+ directly from Samsung running on Verizon's network.
I can't seem to find a way to enable the HD Calling/Video Calling/Advanced Calling features.
Some rumors suspected if you installed the MyVerizon app it would enable the advanced calling menu, but that didn't work.
Is there any way to enable these features?
Is there a command through ADB to enable this?
Would I need root access?
EDIT: Model Number: SM-G965U1 - Snapdragon

No way to get Video and WiFi calling to work (yet), but go to Connections, then Mobile Networks and you can turn VoLTE Calls on or off, which is HD voice. It was there by default on my unlocked S9+ on Verizon. If you don't see it, you may need to add HD calling to your Verizon plan (it's free, but you have to login to the website and add it as a feature).

Ahh, I already have VoLTE enabled. Guess I will have to wait until someone finds a way to enable those other features.
Thanks for the info!

Whatsapp and Duo appear to support video calling over WiFi

Yeah, I know that they support video calling, along with a ton of other apps, but there is a native video calling option.

They got it working on unlocked S8, using some of the APKs and CSC from the Verizon phone. See below:
https://forum.xda-developers.com/ve...to/how-to-video-wificalling-unlocked-t3615027
Or just by flashing the whole Verizon firmware on the unlocked phone (kinda defeats the purpose of getting the unlocked phone):
https://forum.xda-developers.com/ve...axy-s8-unlocked-version-wifi-calling-t3699806
So I'm hoping it's just a matter of time, as I also need the WIFI calling to work on my unlocked phone. I think that's what is needed in order to send texts over WIFI via the Verizon Message+ app, which is what I ultimately need when in poor signal areas (sending texts over WIFI, without getting a second number with Google Voice or asking people to install secondary apps like Allo/Duo). Or I could just switch to T-mobile I guess, where all these things work with the unlocked phone without the additional hassle.

Here is to hoping we can get wifi calling and native video calling working on the unlocked s9/s9+ phones for those of us on verizon.

I have the S9+ (G965U1), and I have used the included Wi-Fi Calling app.
Look for Wi-Fi Calling.

I just got my unlocked S9 what do I need to do to get everything working on VZW I mean HD Calling, and video calling etc.? I've never owned Samsung Phones, I've always had unlocked bootloader HTC phones that I could do anything I wanted with. I don't know anything about Samsung accept "Odin". I still havn't put the sim card in cause I was thinking of returning the phone.

Thanks for the hint Dudeman456! I found WiFi Calling under system apps and went to its settings and activated its permissions. Now I can send text messages over WiFi using Verizon Message+ app (and not the included Messages app or Android Messages). I still don't have WiFi calling through the default phone app on S9. I wonder if there is a different phone app that I need for that purpose (Verizon Phone app?).

Same issue as my unlocked Note 8 I got from Sammy. You can enable video calling in the *#*#4636*#*# menu. You will not be able to activate WiFi calling though unless you flash the Verizon firmware. You also will not be able to use any Verizon features such as watching NFL games (but I think that is changing and won't be a Verizon exclusive) and premium visual voicemail. Really is a deal breaker for me.

What in the world does this mean "*#*#4636*#*# menu"????

All,
This is a KNOWN issue with Verizon.
I got my S9+ on Wed 3/14 from pre-order and could not get video calling to work. Went to Verizon store on Sat 3/17 preparing to wage war with them. The Verizon tech stopped me in my tracks and said it's already known. An email sent from corporate to all verizon stores indicating the problem with video calling. It is an issue with Samsung software which they are "diligently" working to correct and will push an update soon.
Notice this.. go to either MyVerizon app or the website and login. then go to devices/manage devices...then go controls then to adjust service blocks and you will see the video calling is blocked and cannot be unblocked. Apparently this is done for "our own good" until Samsung fixes the issue.
No date from the tech on when a fix will be issued.
DONT try anything crazy to enable video calling..just be patient and wait for the fix. My S9+ is unlocked too and i was assured that video calling will be enabled once a fix is issued.

That is odd. I am using my G965U1 on Sprint and my Wi-Fi Calling app is in the regular app drawer with everything else. I did not expect it to work, since it is Sprint, but it did. The Wi-Fi Calling app was available before placing a sim card inside.

I don't think it will unblock. If you didn't buy the VZW branded phone you most likely won't get video calling. I assumed this from the start. I spent a good portion of the day speaking with a VZW 2nd level support engineer supervisor with 20 years experience. He asked is there anything else that could be done besides unblocking video calls to make me happy, because that at this time it is impossible as the phone is not a VZW phone. Look in you phone profile on their website, does a picture of your phone show up? My profile is blank, that means the phone is not in their system of phones, even though I flashed the full VZW package with bloatware and all after first a full reset. My Phone has VZW splash screen and all the advanced calling menus, in about phone it says SM-G960U, but that block cant be removed. Maybe I screwed up somewhere and alerted them by booting with a sim card in? Maybe they flagged my IMEI? I don't know but the rep said point blank they can't unblock video calling on that line, and unlocked phones are not supported.

Are you all seeing LTE+ (carrier aggregation) on your Verizon S9 devices? I'm in Vegas and my device appears to sit on B13 (700mhz) and does not hand off anywhere else.

Yes - unlocked on Verizon.

You need the right apps for Wi-Fi calling and some in framework. I don't own a s9 but that's what you need to do to get it to work. Along with some csc edits

Samsung S9 Wifi Calling ROM Question

I have a new Sprint unlocked Samsung S9 SM-G960U1 and am trying to get the wifi-calling to work with Cricket Wireless. Currently the wifi calling option doesn't even show up. I was wondering if flashing an after market ROM would enable me to access the wifi-calling feature. Cricket supports wifi-calling, but only on Android devices purchased from Cricket (a note I didn't see before I bought the phone). If there is please letr me know which ROM would help me achieve this.
Thanks

Wifi calling and volte do not work on byod there is no roms for this phone. You can root but I can assure you this isnt gonna work either. All you can do is buy a cricket wifi calling enabled device

incorrect. it merely needs to be provisioned by cricket on the back end by someone who isnt the typical moron with a headset. the reason byod devices have trouble is due to the IMEI not being listed in their system and it takes a ticket to be sent to the telephony dept and have it added. They dont like doing it, but they will when pushed. Unlocked A8 and A6 on cricket both had wifi calling and VoLTE after provisioning was complete.
you also have to have the right csc on the phone.

I have a method with imei from a good cricket wifi calling phone. And have it working. But I have to give them another imei once I have it provisioned. Once their system updates with my imei I lose my wifi calling. But after provisioning I give them my actual cricket devices imei and tell them the system is still showing my byod imei they need to change it back to the other device. It works. But imei in their system is wrong.
Not imei switching or anything like that. I physically own a stylo 5 from cricket I dont use. So they think I'm on that and not my g9650. So I know it's possible just a real pain

Question S22 hotspot workaround

Has anyone discovered a workaround for the message "to use mobile hotspot you will need to subscribe to a hotspot service"? I have unlimited data on this line and I would like to use it. Thanks a ton!

That will depend on your carrier. Have you tried the USB route?

Carrier is Verizon. Was hoping not to use USB. Any idea if root / unlocked android will fix the issue?

Try pda net. Some carriers in their infinite power to be an ass block it on the play store. But pda net devs don't give a **** and put it on their website.

What about with T-Mobile? Ever since switching from Sprint SIM to T-Mobile SIM, adding ",dun" to APN doesn't work anymore. Currently using S8+ on Android 9, if that matters

Rooting won't help and it's probably not worth the effort. I've used PDANet back when I had my original Verizon unlimited plan. I could connect via USB.

I used to flash the U1 firmware to bypass this when I had a plan that didn't support mobile Hotspot. Before that I used PDAnet for usb tethering or even a different APN setting to prevent blocking.
