Can't find network, no data, WiFi works fine though. - Galaxy Note II Q&A, Help & Troubleshooting

Got this phone with the problem already, I installed a custom ROM hoping that would fix it but still doesn't work.
Cannot find network, though it is showing 3 bars?
Can't make calls, can't use data.
WiFi works just fine.
EDIT: Should probablly give some more info:
T-Mobile model
ROM: CleanROM A.C.E.
SIM card works fine in my other phone.
EDIT2: Ok so after more fiddling I got it to pick up a signal from AT&T with the "Find Network" search. I'm thinking this has been locked to AT&T and I just need to flash back to a stock ROM and unlock it, thoughts?
I know I get T-Mobile signal at my house my other phone picks it up just fine and I'm using the same exact SIM in both.

Maybe someone has flashed a wrong modem/rom on the phone so it ruined everything..
You said it's T-Mobile phone.. I guess it's gotta be locked to t-mobile..
I would suggest to post this on T-Mobile Note 2 forum.. They would know a way to solve your problem.. This forum is for international note 2..

*#06 etc to get your imei display on the phone. Check imei matches with imei number underneath the battery. If they match and apeears to be valid you may have a locked or blacklisted phone. Blacklisted means its imei blocked nationally due to fraud such as lost stolen and insurance replacement provided etc.
Good luck

T999 to Metro

I have an S3 rooted with 4.3.
I have a Metro PCS sim which I am trying to use with this phone.
The phone seems able to read the sim OK.
Under status I can see my phone number.
Everything else is unknown. Network is unknown, Mobile network type is unknown, service state is out of service.
I get full signal too, but when I go to mobile networks, I receive a message "Insert SIM card to access network services"
So I can see my phone number, and I dont have a message telling me to insert sim when I start the phone.
I have checked with Tmobile and I know the phone is not black listed, but when I make a call I get not registered on the network.
I do see also my IMEI number and seems to be correct under about
I really dont know where else to look for answers. I would love some help with this.
Any ideas?
Anyone?
Do you have the 4.3 modem? And also did you add the device to your line? Otherwise it won't work no matter what you do

The Baseband version is T999UVUEMJC.
I tried to add this phone by contacting Metro, and they told me that they couldn't because the phone is locked. I contacted T-mobile, and the person sent a request to get it unlocked, and said that I should wait 72 hours to hear from someone. I waited more then 72 hours, and I called T-mobile again, and then I was told that I needed to have service before they could unlock the phone. I was not sure if that was the issue since the phone did not give me the invalid sim card error.
I went to Metros site to see if I can check the IMEI. Their system said the phone was lost or stolen. I called T-mobile to check on the IMEI, and they told me its fine and there are no blocks, and ready to activate.
I also confirmed the status using both Swappa, and checkesnfree. They both say the phone is ok. I would think just using the Sim should work, but I am not sure what to believe.
Ok there are 2 things you need to do.
1) update your modem to a 4.3 modem
2) add the device to your line.. Just swapping sim cards will not work. It also doesn't need to be unlocked.. Any T-Mobile phone will work with metro as long as its in a gsm market, so you might want to try doing it again.. I worked at metro so that's how I know all this
Edit: never mind you do have a 4.3 modem my mistake for reading too quickly.. But it looks like you're set to go, you just need to add the device to your line, so try adding it again

[Q] please help - galaxy s3 no signal/not registered on network

so I have the galaxy i747 on att unlocked.
a few weeks ago it bricked itself trying to over the air update. I couldn't fix it so I had it jtagged and it came back. I also paid for an imei repair.
everything was fine, I could make calls and stuff but eventually lost signal.
I sent it back as I ended up bricking it trying to restore to stock rom (it was on philz touchwiz)
he fixed it, said the network problem was due to my simtray.
I replaced the simtray today, I had full signal but when I tried to make calls there was no dial tone and ive lost signal again, this time its running a hyperdrive rom. my simcard is TESCO which shares a network with O2.
it picks up the simcard and stuff im just not getting any signal, when I try to register on the network it says unable to connect.
if anyone could please help me with this I would really appreciate it! alex

I would check your IMEI/baseband. Make sure they're correct.
Also, could check your APNs.

[Q] Enable Mobile Hotspot on Unlocked ATT Galaxy Note 2

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.

Phone Stuck Showing "Searching / No Service"

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.

Ported AT&T from Cricket (AT&T), nxtgenphone APN gives no data?????

So I jumped on the AT&T/DirecTV Unlimited data deal and ported my phone today. It all looked normal and I got the activation texts and such - it even populated the nxtgenphone APN info (though it was deselected and I had to select it). Anyway, I've had no data at all. As a test, I switched the APN to phone and data works, but the speeds appear to be much lower than what my wife's iPhone is seeing on the nxtgenphone APN. Anyone got any tips?
I'm running Viper 2.5, latest US unlocked firmware and US unlocked selected as carrier, and it works fine on AT&T other than this......only other thing I can mention is when I select preferred band or whatever it shows WCDMA/GSM and if I change it to WCDMA/GSM/LTE it reverts back for some reason. Any help much appreciated. I've called AT&T and they're like, uh, we don't sell the HTC 10 so can't really help you... grrrrrr.....

I'd suggest ruu to stock us unlocked rom and see if the issue persists.
Or, try clean flash of viper.
I have no issues using US unlocked on AT&T with both stock rom and ice.
Thanks for trying to help. I just finished trying stock RUU and same problem. I'm convinced, as I was before, that this is AT&T's issue. I've read numerous posts this afternoon that because the HTC 10 (and other phones) aren't in their "LTE approved" database, nxtgenphone APN won't work, or it will only give HSPA speeds. Seems like everyone who has resolved it, or didn't run into the issue at all had another AT&T LTE phone they could use for the IMEI on the account, or the rep entered the model as an iPhone or similar to make it work. Really, really frustrating, as they refuse to help me and I'm starting to think I should just terminate in the 14 day window and do T-mobile or Verizon.
I have at&t and everything worked out of the box, I've never been on stock rom, always on Viper I did the unlock and s-off without a sim and never had an issue or called at&t to activate the device I just transferred my sim from my note 4 to the HTC 10, no provisioning issues at all, VOLTE works, LTE is fine as well while on a phone call... No issues... If you need anything to compare let me know

Thanks for replying. They did confirm it was a provisioning issue and they fixed it today. They had to do something different, as the default HTC 10 provisioning and IMEI check didn't fix it even when they tried it a second time, but they were able to adjust something and LTE definitely works now. VoLTE working here, too. Thanks!
