Hotspot on a International Unlocked A71 4g - Samsung Galaxy A71 Questions & Answers

Hello All
Has anyone been able to use hotspot with out activating with the carrier? I have ATT, with my Samsung S5 I was able to us hotspot freely( its just internet!) once I rooted the phone.
On this A71 4G, I can activate the hotspot but once my laptop connects to it I have no internet
Does this mean I must root the phone to unlock the hotspot abilities?
One UI : 2.1
Baseband version: A715FXXU2ATF7
On the root guide I see that it says "WARNING: You can't downgrade anymore once you flashed U2 update !"
I see a U2 so I maybe on that update? Anyone know for sure?
Thanks All!

Ive been having the same exact issue. I have not tried to root though.

Yes, sources say you can get internet if you set up a VPN.

[Q] Rooting N900A to Lollipop while using T-mobile.

Ugh, I am having so many issues with this at the moment. One of those things being that I am using T-mobile as my carrier. I'm stuck on 4.4 at the moment, and need to update it. But, will that relock the phone? How do I re-unlock it if that happens? I've already read that I can't flash the phone to T-mobile ROM, but are there any custom ROMs that you would recommend [I do actually use the S-pen, not sure if any have been updated to where that can still be used.] Lastly, is there any way to get mobile hotspot and tethering to work now that I am using tmobile?

I never tried this Rom.
T-Mobile Alliance Lollipop Rom on ATT Note 3
http://forum.xda-developers.com/note-3-att/general/t-mobile-alliance-rom-att-note-3-t3065127 I don't think you would have to worry about any of this as you are using T-Mobile " After the phone came up, I went to settings..general..applications...running .... and found every Tmobile app and cleared cache and disabled them. The real important one here is the Visual Voicemail. Otherwise it will keep on trying to contact Tmobile and then you will get text messages saying there is an error. Thanks @sapps
Wifi Calling is throwing a sim card error (as you would expect). Only problem is it is shown in status bar and lockscreen. I'm sure there is a way to hide it or disable it. I just haven't had a chance to figure it out."

But it's the N900A, so it's the AT&T version. Won't that brick the phone if I put the tmobile ROM on it? That's what I've read in other threads on here anyway. [Honestly I shouldn't write when I'm tired, or I would have explained this better.]. Basically, I bought an unlocked AT&T phone. A Note 3 to be exact. It's stuck on 4.4 but can upgrade to lolipop. Nothing I try will let me upgrade the normal way. I'm not sure how to upgrade it without relocking the SIM card somehow. Or is the simcard already semi-locked and that's why it's giving me the error? I also can't even find a AT&T specific rooting guide for this phone. I saw every other carrier except AT&T, does that even make a difference? And are there any ROMs that can return S-pen programs after I install them, or should I just stop at rooting if I want that? If so, I just really want to upgrade to lollipop and root the phone. I would like my mobile hotspot and wifi calling to work, but I suppose I can make do with hangouts.

It won't brick you phone. It's a T-Mobile Rom that's been ported for AT&T Note 3. After you flash the Rom, you have to Odin the N900A_OC1_ALL_Other_Stock_Partitions.tar.md5 using Odin's PDA slot. As far as rooting what you have now, just use Towel root https://towelroot.com/ (install on phone like any other app) and click "make it rain". Install Supersu, busybox and Safestrap. OR use Kingo Root http://www.kingoapp.com/ (Kingo Root will install supersu for you). The reason it won't upgrade to Lollipop is you have a T-Mobile sim card in it. It needs a AT&T sim card (I have AT&T and can't upgrade mine unless the sim card is in the phone). If you just want a rooted Lollipop Rom, but it's AT&T http://forum.xda-developers.com/showpost.php?p=59666958&postcount=2 You know since you're on T-Mobile you have to go into settings>more networks>mobile networks>access point names and change it to T-Mobile's APN. I would just root it and put the T-Mobile Alliance Lollipop Rom on ATT Note 3 on it. I gave it a try yesterday and it does have T-Mobile apps on it, just not for me. Just remember to change the APN to T-Mobile's ( just write down the one you using now).

To my knowledge you can't downgrade the bootloader. What carrier/country? You may just need to update APN settings or something like that. Wifi calling may depend on CSC file too (or require a call to your carrier in some cases)...
USA--> Tmobile.
but why doesn't wifi calling feature does not appear anywhere

No! Sorry!
You can try another firmware with N950FXX"s5" or "u5"C***
But you can't go back to N950FXX"s/u 4, 3, 2, 1"*****
If your rooted you can just flash a csc zip file containing your cell providers csc. You can find it by searching xda.
But you'll lose Samsung pay, secure folder for good no getting them back without changing motherboard.
thanks
I could not able to understand which csc is for usa

For USA tmobile is TMB but you will not find that for your phone model SM-N950F. It's only for SM-N950U or U1.
Only way is to root your device and flash the zip file containing the TMB csc .

You can try csc detonator maybe. As far as i know tmobile doesnt allow phones volte and wifi calling if you dont buy from them yet i dont have many knowlagde on usa models and tmobile but you can take a look at csc detonator or tmobile csc threads
I am experiencing a similar situation, but noticed that the new bootloader after u5 is "S5"? But are both compatible between each other, I don't think they are.

VoLTE doubts on SM-N960U1

Firstly I own a Samsung note 9 Unlocked SM-N960U1
I saw some threads about using the IMS menu to change it
But I couldn't open it as I was on oreo
I saw an app and was able to open the following:
[LINK]https://i.imgur.com/HHniykj.jpg[/LINK]
Is it the IMS menu?
Then when I checked my phones IMS Service status
It showed the following:
[LINK]https://i.imgur.com/97IfSn0.jpg[/LINK]
When I checked the IMS Status of a phone that supports VoLTE
It says that IMS is registered and all others are unavailable except VoLTE and video calling
When I talked with customer care that volte doesn't work but you can use Airtel or other ISP than jio to make calls
I need a way to use VoLTE on my phone without root and bootloader unlock (as it is not possible to do both on a snapdragon Samsung device)
I have kept the image links like above as this is my first post and I am not able to add attachments

You need to flash carrier firmware to get WiFi calling and VoLTE working. The only carrier that supports WiFi calling and VoLTE on the U1 firmware is T-Mobile. I'm assuming you're on Verizon or ATT?
I am in India and I have an N960U1
So flashing is also not possible

Ok then it probably won't work in India. You need the international N960F model.

Even with the f model I seem to be unable to get this working. Says 'permission denied'. I have root as well and have done the firmware flash obv..
If you have an f model why did u have to root it.It is supposed to work directly also
I'm in the same situation now. Not able to use Jio. Were you able to fix this issue?
I own a N960U1 and I'm in south America, I can use VoLTE with my current network provider with no issue. Only problem is the VoLTE option disappears whenever I get updates here in south America. Last update I was in Canada connected to Tellus network and the option appeared back. Same happened in past December when I was in US connected to ATT network, VoLTE appeared back in settings after update, next update I was back in home and no VoLTE after. How do I keep that option whenever I update phone in south America? I've already tried updating with no sim, no network connection, airplane mode ON and location disabled, it didn't work. My guesses are phone takes info from last network it was connected to and then enables/disables options based on this.

In fact i kept the phone aside for 2 months as it wasn't compatible with Jio.
I started using with Jio using jio voice calling app 2days ago.
I was on April security patch.
I've updated it to May version last night, after updating, VoLTE started working. I was surprised.
Now there's another update showing up but am hesitant to update.
Check my screenshot i posted as attachment.
Flash April version, start using via jiocall app then update to May version if you are still having issues.
Thanks for the response. With lost of research I found a solution which worked for me.
Just changed the country in Google play store to India and restarted my phone and Voila, there appeared my VoLTE sign on top and able to use it like a regular sim card. I'm going with all the updates and no issues.
Hey,
As per the image image attached, the firmware you are talking about is U1 ATT May Update . Is that correct ?
Currently I am on April U1 update without carrier and going through the same problem(Jio Sim and No VOLTE , so cannot make voice calls)
Where can I get May Firmware for U1 ATT .
Thanks in Advance.

Hey, so my phone was in April update U1 Unlocked , and upon checking for updates it showed me 800MB of update of N960U1EU2CSH2 . After a more researching , I just took the leap of faith and updated the phone and wolah, VOLTE and WIFI Calling Enabled. So I Guess the later updates after May are working well and they have not removed the functionality.
I can also conclude this carrier bloat slowed down the phone like crazy with the Lag and now the phone is soo smooth and responsive without it.
Thank You again for the Prompt Reply.

Hotspot not working on TMobile 4a 5G

My friend has a TMO 4a 5G that will allow a computer to connect to it for a hotspot, but will not provide internet access. The computer gets an IP but it's like NAT isn't working. Has anyone run in to this issue before or know of a fix? The phone is stock with a TMO e-sim.
No issues here on MetroPCS/T-Mobile... Stock... Not rooted... Locked bootloader... Regular (nano) sim
bobtheelf,
Can you tell me what Build Number you have on your phone.
Thanks

No gsm network on s10 sm-g973n

Am currently having issue with Samsung s10 sm-g973n on Android 12. The phone is able to read sim card but its not connecting to network. It shows it has imei. I have tried customs roms eg blastui and still nothing. Any idea how to resolve this?

Am able to flash stock rom but still no network. its says emergency calls only. i tried KOO, SKC flashing completes odin, boots up wells but no gsm network. That's why I even tried custom rom. am able to flash stock back but still nothing.
Am thinking could the issue be around corrupt imei? any ideas how to repair it. or possible csc issue? am currently in kenya. Btw the issue started after last security patch update. possible to downgrade to maybe Android 11? would that help?
Hello Bashir22, your model does not have an Er Europe chip plus a Korean so Europe is not possible with a sim card.
If you put a chip for the Europe network and you have a chip for Asia, it won't work.
My worry is it was working just fine till last update.

Dial *#0011# and check if you have your IMEI Status: OK, if it says anything other than OK then it should be a cert problem.
