Hello,
I buy a Samsung S2 T-989 locket in T-Mobile. I buy an unlocking IMEI code and it worked perfectly. My problem is that when i try to use Thetering and Mobile HotSpot i receive the message "Mobile data is not available or invalid SIM". The only problem is "invalid SIM" because i have internet. What can i do to fix this problem?
Need more info.. stock/root/custom rom? Are you on T-mo? What plan are you on? If you have the new unlimited, then it does not include tethering. Does your interweb work normally? If you are not on T-mo, the stock hotspot app will most likely not work and/or you need to change your network settings for whatever carrier you are using if not T-mo.
i'm from România and i use Cosmote network. my phone is stock. where is the setings are you talking about? maibe i can change them.

Ok, this may be a dumb question, BUT...
Do you have a SIM card in there?
AND,
Do you have a T-mobile account?

lmao, yes and yes
unlimited data plan too and connected to wifi
I had the same problem -- because my SIM was pretty ancient. It was actually a PowerTel SIM (who got bought by VoiceStream who got bought by T-Mobile). Just drop by a T-Mobile store and get a new SIM. It's quick and free.
PS -- In my case, the "My Account" app didn't work, either. It would always say "cannot retreive account information at this time" or something like that. But literally everything else on the device worked fine -- voice, data, SMS, blah blah blah. Even T-Mobile TV.
It was just the stuff that needed specific T-Mobile account information would fail.
Well I have this issue even though I just got a brand new T-mo contract on Thursday so I doubt the sim is ancient?
I realised the problem.
I'm in the UK.....
Call in and add world class roaming for free and wifi calling should work fine

That worked for me. It no longer says invalid SIM!
I didn't even have to call. Just go to settings> wireless&networks> mobile networks> then enable data roaming fixed it for me. Using G2x. This was driving me crazy at first because wifi calling worked fine when i first got phone then after flashing a rom it did not work. This fixed it for me, i know its old post but hope this helps someone else too.

When i wrote my first reply i did not realize this post was for the G2 not the G2x, maybe that's why it didn't work for you, on my G2x international roaming does not need to be on, only national data roaming, i also had to reboot phone after turning roaming on. If this doesn't help i would suggest doing what others have mentioned, call t mobile. Maybe for the G2 the roaming needs to be enabled on t-mobile's side, i really don't know for sure. Good luck, i know how annoying this can be, as i get no cell coverage in my bedroom, so wifi calling is my only option for me. Sorry I couldn't be more helpful.
Hi,
I unlocked my AT&T Samsung Galaxy Note II 4.1.2. But every time I try to send a text message I get an error message saying message not sent. I'm not sure how to fix this issue. I'm right now not using the AT&T sim card but an international sim card.Please let me know if there is anyway I can fix this issue.

What network are you on?
Are you able to make phone calls?
Have you checked your apn's?

I'm on Airtel here in India. I am able to make calls and I have checked the apn. Whenever I turn on the mobile hotspot the message I get is "mobile data unavailable or invalid sim".
Have you checked the baseband of your radio?
If it was just the hot spots it would be the att tether blocking. But to confirm you cannot text either right?
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.
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.
Dear sir,
Please give me step by step solution for this issue.
4G working fine but hotspot and usb tethering not working in India.
You mean you can't turn on hotspot on the phone? Does your cell company need to add hotspotting to your account?

yes, I mean that. when i tap on Wifi hotspot ON-OFF it says no network or invalid sim. same in usb tethering option. but sim is working fine in 4g network in mobile and internet working fine also in mobile. if still i am unable to make you understand then i can send error screen shot.
Does your carrier have to enable hotspotting? I'm in Canada and some carriers need to turn on the tethering for the account.

No, I am in India and using JIO 4G network - Indian sim (not AT&T) and they don't required to enable hotspotting from their network.

I am too facing this problem with Indian JIO network. Is there a way to enable WiFi Tethering ? Can flashing CM helps overcome this issue ?
