I have a unlocked Samsung SGH-I747 from ATT its mobile data tethering is not working. Error message "Mobile data is not available or invalid SIM" appears. I have rooted the phone with SUPERSU. I am a amateur at this I rooted the phone following instructions on youtube and xdadevelopers. Its working fine otherwise.
Could someone help? I don't have internet at home and want to use the simcard to connect. I am using a simcard that allows tethering on a normal smartphone. No problem with the simcard.
Thank you for your help.

Hi,
so I have an unlocked AT&T G850A that I'm using on T-mobile. When I tried to enable the hotspot, it gave me an error "Mobile data is not available or invalid sim card'. After long research, I learned that i need to root the phone and replace a file. I searched all over the web, but couldn't find root files for the G850A.. I'm currently using PDanet to connect to the internet using a USB, but i really need to get the wifi hotspot working.
IF anyone knows any solutions please let me know.

I am in the same situation but I dont need hotspot on this phone. I remember someone telling me it cannot be done if you are on KK 4.4.4.
But once you update to Lollipop, then the Hotspot will work on T-mobile. I read someone. Maybe someone can confirm.

See I can't even do that because I have a t-mobile sim card, and it won't let me update unless i have an AT&T sim card.

SM-G850A AT&T Unlock Issue
Hello,
Hope you guys are doing well. I followed the above thread and re-flashed the firmware as recommended. However when I try to enable the mobile hotspot functionality it states that I must contact att to enable hot spot functionality. My carrier is straight talk. I just wondered if they are locking the tether functionality at the sim card level? I was planning on using the hotspot with pda net. I will mention that I left the EFS partition entact since it contains me IMEI info. Not sure if I needed to wipe any other partitions before I flashed this firmware. Thank you guys for all the help.
Thanks,
Coop
How to Hack Your Samsung Galaxy Alpha SM- G850A into a Free Wireless Hotspot even it is unlocked from AT&T?
hello guys,
i am using Oneplus one, i have recently unlocked the bootloader and rooted my device, its running on marshmallow(6.0.1) CM 13.1.2(bacon) now. I am able to use the 4g internet service, but everytime i try to register i fail,its just stuck on the page itself where it shows "Registering with Jio sim". I feel helpness now tried clearing data,reinstalling the app, but nothing worked. i am not able to make or receive call and messages.
Is it something to do with the root or IMEI? or what is the actual problem? i have rooted my device following the instructions from Xda itself.
please note I keep changing my IMEI using device emulator for some purpose, xposed module is installed as well, root is hidden using "hide my root app".
So i recently rooted my phone and messed around too much, now i need the stock rom. I download the Alcatel mobile upgrade software and started "upgrading" if u will, but it comes up with a network error saying i need to check my internet connection.
Am i doing something wrong, did i forget something trivial?
