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.....

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.

I went to the store this morning and they said if you have the newest sim which comes with the phone, then you will see it in settings.
There is no wifi calling at launch, you do need to use the new sim in order to support a new wifi calling feature later this year

I Havent got mine yet but my wife works there and supposedly you have to use the sim card that comes with the phone
Can someone who has the phone actually try to initiate a call with wifi calling?
You have to have the new sim that came with the phone. This will not work with an old sim from your previous phone.
I'm using the new sim that was in the box, and i'm not seeing how to initiate wifi calling.

Nope... I see only two checkboxes... Wifi (Enable/Disable) and Network notification... below that is WPS button conneciton and then the list of wireless networks.
I appreciate you looking onto it. That sucks if that option isn't or doesn't become available.
i took mines back because of this and hotspot being blocked.. grrrrr
Okay back i called t-mobile a couple of times. They thought the people were talking about sip, skype, voip calling. Not the wifi calling that t-mobile made. The one that seem to most tech savy rep said there will be a patch to add it but don't know when it will come. The amaze 4g already has it build in under wireless settings.

Not enough for me to return the phone but really need that option. Oh well....now we wait
For kicks I installed Kineto (Wifi Calling app) and tried to run it... immediately FCs. Oh well. Perhaps this feature can be "unlocked" with a custom ROM that re-adds SIP support to the device. I thought I read somewhere that it is excluded by default.

we would have to wait till samsung makes a wifi calling as the one we have now uses htc libs. Sip support is there just not wifi calling for t-mobile sip comes with all gingerbread phones.
Hey guys, I just got my Hercules (My precious!) in the mail and I am having a
network problem. I am currently on T mobile unlimited data (3G), minutes and texting and Wifi works fine when browsing on the internet
The sim card works perfectly on my Vibrant
Here are some screen shots that might be of help.
PS: No I am not from the future, disregard the time on the attachments
EDIT: I tried factory data reset/SD reset and it still didn't work.
Thanks!

under settings>wireless and network>mobile networks>, make sure the first option "use packet data" is checked. i've had a couple time that it was unchecked and therefore i had no data connection, but the phone still works in calls and texts. hope this helps.
I rooted and flashed the Juggernaut and checked and unchecked data packets and nothing works. Data, texting or incoming or outgoing calls do not work. I talked to Tmobile rep today and she told me it might be because my sim card is old, so I am going to get a new sim card tomorrow and hopefully it will work.

New sim card will be a 4G sim. Old ones according to T-Mo rep was a 2G sim. Newer phones need the newer sim card to run properly.
You need the new TM9177 sim card.
Go to a store and ask for one, just make sure they don't try to make you pay for it.
Hello, I bought and unlocked a HTC M8 but now I have put my sim in everything apart from there is no data connection, Wi Fi works but not data. When I go to Mobile Data in settings it says "disconnected" and when I go to APN it says " Access Point Name settings are not available for this user" Is this the problem ? Can anyone help figuring how to data connect ?
Thanks
Have you selected your network operator first.

This is one of those things that can be most easily solved by calling your operator. When I got my phone and put in the sim card, I had no data. I called O2 and they guy walked me through the setup. It might be a noob way to solve problems, but it definitely works.

It did not matter for me. I have an unlocked phone and a sim card from O2. O2 is providing me with the service, it's their job to make sure it works. My phone was brand new, so it would be safe to assume that there was nothing special about it. Also, here in Germany I can always return the sim card and void the contract within two weeks after buying it, so the network wants to keep me happy .

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

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.
Hello all. I purchased a edge+ today but whenever I insert a sim, the phone stays on searching. I made sure that I rebooted the device and I also tried re-seating the sim many times. I believe the device is unlocked and the imei/esn is in clean standing with T-Mobile. I tried a MetroPCS sim card and it stayed on searching, same thing happened with a Verizon sim. However when I inserted the T-Mobile sim, it sometimes says no service but ever since I rebooted the device, it stays on "searching" no matter which sim is installed. I find this whole ordeal frustrating since the signal bars show up for the MetroPCS and T-Mobile sim but with Verizon nothing happens. Any help would be greatly appreciated.
Yours is G928T? If yes, it does not support Verizon/Sprint even if it's unlocked.
Did you buy it off of Craigslist/Ebay? It might be blacklisted. checkesnfree.com

Yes, it's the G928T but it's not blacklisted I checked. The simcards I was using on the phone were old ones(no longer in service) I thought they would work. I used a scissor to cut my WORKING sim and placed it in the phone and it took the MetroPCS sim. Everything works fine now except calls and text only work with WiFi Calling on. If I turn off WiFi, I can't text or make calls(not on registered network) but if I turn the WiFi back on, it works fine. Any suggestions?
MetroPCS and T-Mobile are on the same network.
Check/add MetroPCS APN.
Setting -> Mobile Networks -> Access Point Names
Add MetroPCS APN if it's not there.

Yeah I know they are which baffles me as to why it isn't working. I tried adding a custom APN but same thing happens. I get calls/sms on WiFi but if I turn it off I get "No Service"
Just go to metro and get a new Sim. You could have damaged it by cutting it. It should be free. ATT gives me then free all the time. Usually, the phone will just auto update the apn settings when a specific carriers Sim is inserted

I went and it turns out the device is blacklisted. This whole time I was rolling with the imei in the phone, after checking last night, I noticed that the imei on the back of the device differs from the one that's actually on the software. I was able to get in touch with the seller and he's coming back to give me my money back. Guess a mod can mark this thread closed.
