Hoping someone can help me out here.
I have an unlocked, AT&T branded SG3 (SGH-I747) on the T-Mobile network. My plan allows for tethering however when I try to turn on my mobile hotspot, I get an error, "Mobile Data is Not Available or Invalid SIM".
What I am having a hard time figuring out is if I have an issue with the SIM card or if it is a hardware issue in that I need a T-Mobile version of the GS3 (SGH-T999) to be able to tether. Any light you guys can shed on this would be appreciated.

Bought my phone form Rogers. LTE was working fine.
Was going to USA and paid an online company to send me unlock code.
Used it and went using Tmobile which only has EDGE data.
Just got back swapped back in my SIM From fRogers and can only get EDGE speeds.
Tried reboots rmoving SIM card.
Also made sure settigns were correct for Rogers APNs and also that toggle was on for GPS/HSPA/LTE.
To no avail.
Briefly, I toggled on and off the apn setting from ROgers LTE to tethering LTE and low and behold it seemed to work.
But now it is back to stuck on EDGE and nothibg I am doing can help.
Can this be a byproduct of the unlock?
Is my LTE faulty?
I s there some hidden menu where perhaps a setting can be changed for a fix?
I am depserate as the alternative is to return the phone and they are on backorder everywhere now.
There is no lte on tmobile yet. Second the tmobile note 2 has dormant radios that will only activate the lte capability by software update.
Im going to research your problem a little more ill send you a pm as to why it isnt going back to lte functionality if I find out something first...

I have a Canadian note 2 that had working LTE.I had it unlocked via a code emailed to me then next used it on tmobile at edge speeds.
Since returning home i cant get back onto data speeds above edge despite reboots.Simcard/battery pulls.
I ensured my network and apn were correct and that in setting under mobile the toggelchoice for auto including gsm//hspa/LTE was selected.
Are there perhaps some deeper settings via dialer code than might be able to turn back on the hspa/lte radios?
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.
Is any one else out there getting Data connection with other carries after unlocking and rooting there T-Mobile Samsung galaxy s 4?

Try changing the network operator or the mobile network and see if your not using tmobiles instead of at&t...

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
unlock isn't network unlock?

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!
I rooted my S4 Mini (SPH-L520) phone using the procedures found here: http://androidxda.com/root-samsung-galaxy-s4-mini-sprint-sph-l520
This allowed it to be flashed to Boost. Talk/text/web/MMS all work.
However, I have three problems that appear to be related to the phone thinking it is still on the Sprint network:
First, I keep getting a sim card error that says, "The network did not respond in time. The SIM card has locked. Please power cycle the device and if the problem persists contact Customer Service.”
Second, I keep getting a "MIP 67" error.
Third, I can’t get a WiFi Hotspot program to work. The programs will start, but within a minute I get "Unable to connect to data network, turning off Hotspot. Your plan may not have the Hotspot service. Do you want to see subscription options?" If I click OK, it tells me "Network is not available." and ". . .dial *2 from your Sprint phone or call Customer Care. . ." Tethering with Boost worked fine with my old phone (TP2).
Is there anything I can do to fix these problems?

I saw something about changing APN settings on a GSM phone. Does that apply to CDMA phones as well, and might that provide a solution?
I'm getting the same errors, 67 and 89. It thinks it's still on Sprint, it was already running on PAGEPLUS, then lost it.

Hi, my dad is having a problem with his galaxy sm-t211 that I can't seem to find a fix for, I haven't even been able to find mention of it. His tab is unlocked. He is using his fido SIM chip with it. He gets data fine, but it is constantly in roaming mode. Even when I turn roaming off, it says that he has lost network connectivity because he is out of his home cellular network. Does anyone know if this issue is fixable. Maybe by flashing a modem for this region or something? Any and all help appreciated, thanks
I have a network unlocked ATT LG G4and I am on mobile share plan that allows tethering. I have no problem tethering in the US with my ATT SIM card.
However, when I use another SIM card (for data in europe), I get a message "authentication was unsuccessful" when trying to activate the hotspot.
If I put the same SIM into my galaxy S4, have no problem activating the hotspot and tethering.
Any idea what's going on? Clearly the foreign SIM is fine. And the phone is capable of tethering (on ATT).
I posted this under ATT G4 as well, but I'm not sure if it's particular to ATT.
