hi, cableguychad.. 'mobile networks' in Wireless & Networks is greyed out. i cant access it to access apn. what do i do?

I would try reflashing rom with your sim card inserted. I sets apns on first boot of the phone.

Your APN isn't set to pick up T-Mobile signal so you will have to edit the APN

Try searching, I typed "T-mobile apn" into google and found answers in seconds, far easier than waiting for someone to reply with the answer here.

How did you root? Are you sure you're sim unlocked and carrier unlocked? APN should have nothing to do with making calls; APNs are for data connections.

hi, gene poole.. i used the HTC Inspire/DHD Hack Kit found here:
http://forum.xda-developers.com/showthread.php?t=952352
if APNs is for data, then why the hell did the other forum members on this thread give me idiotic advice on settings APNs knowing i cant make calls?
anyway gene ppoole, i cant make calls. sometimes the tmobile logo appears on the top left corner.. then it disappears. and i made a call that lasted only 15 secs. then i wasnt able to make another call. this is strange. what must i do?

Could we get some background on all this? Where did you get the phone (it's an AT&T phone and you're T-Mobile--why)? Was it damaged, or damaged and repaired? Was it used? Was it obtained from a friend? Craigslist?
I ask because it sounds like there's some problem with the phone's hardware to me. It may be something as simple as a loose connection (if the phone was disassembled for repaires, i.e.). It might be worse. Is it warrantied?

hi gene poole. i got the phone through craigslist. the guy who sold it to me said it was brand new. and it doesnt have any scratches on it whatsoever. everything looks perfect.
as far as warranty, i'm not sure. this is something i can check. but again, the phone looks brand new. i got it with the box and manuals and everything included.
i did flash it 3 times on 3 different roms. and it still gives me the same issue. do you think i should take it in for repairs? if so, where can i get the stock rom so it doesnt look like i broke the warranty?
or maybe i should re-root it and s-off again? maybe this will solve it?

How did you go about rooting it? It might not have gotten sim unlocked and/or carrier unlocked.

hi gene poole.. or, it might not have gotten the sim unlocked properly since the tmobile signal comes and goes sporadically. i made a call that lasted 10 secs before the call dropped. and when i try to call, the call drops immediately. most of the time i cant make calls. and the tmobiile logo appears then disappears from the upper left hand corner.
i rooted it using HTC Inspire/DHD Hack Kit V12.3. the link is below.
http://forum.xda-developers.com/showthread.php?t=952352
i think i should unlock it with another tool. can you provide me with a tool that will unlock and re-root the phone? i really need to solve this issue.. thank you gene poole..

This has proven to be the preferred method of rooting/unlocking. I agree with gene poole that it sounds like either the unlocking step of the root process wasn't done completely or at all. I suggest returning to stock (http://forum.xda-developers.com/showthread.php?t=1208507) and trying again.

I'm still leaning toward a hardware issue. Do you have a friend with an AT&T SIM that could let you borrow it to see if it does wonky stuff with a native SIM?

Is it possible that he had a bad flash of a radio somewhere along the line that would cause it? OP - did you try flashing any radios after rooting?

Getting Cell Service with NO SIM! And some other guys number ! Help

I just bought a phone the guy who made no mention of the fact that it was rooted when I bought it. What is worse is he mentioned that his GF worked for Verizon, which did not seem to mean much at the time. Knowing that here is what i'm dealing with.
I was in a rush when I checked out the phone as I had to meet another person to pick one up for my wife as well. It's the sch-i575 in white 16gb. After having a minute to look at the phone it turns out he had Paranoid Android flashed and the phone was rooted. CRAP! Not what I was looking for and he was not upfront about it. The incredibly strange thing was that with NO SIMCARD the phone was getting 3g signal! I spent all night trying to unroot \ undo what he did. I managed to use ODIN to get back to the stock rom although I think it's still a rooted one since I still have the super user app. I got a sim card from verizon but since it was rooted I did not bring the phone in and when I tried to activate later it would not activate. My wife's by the way is working flawless and when I put my sim in her phone it works fine as well. I had to put the sim in my wife's phone and it activated there. Here is the crazy thing, with or with out a simcard the phone makes calls and has 3g internet only but when I make a call it uses HIS NUMBER!! I'm not sure what the hell to do, what could have he done? Any ideas? Please all help is appreciated! I did not think this was even possible for the phone to function w/o a sim. I'm worried about taking it in to Verizon because of the funkiness. Ty again for any insight...

I thought the I575 was an old slide phone. So A. your in the wrong section of the forum since this is Verizon's S3 or B. you mentioned the wrong device number? I saw phones before working and running on networks without sim-cards but that was years ago. If it is an S3, you sure it's a Verizon device? Also since you see 3g....can you browse around in the browser or make a phone call?

Yes, it's a galaxy s3 16gb in white. It looks like currently I was using the tar66 using ODIN. I'm reverting back to the bone stock one now. As far as the models go isn't the SCH-I575 the Verizon version of the S3?
I'm waiting on the stock unrooted rom to take through ODIN and will report back. Thank you for taking the time to try and help.
Ohh, yes the internet works and when I make phone calls with or with out my sim in it makes calls successfully but the other guys number shows up. What the heck did this guy do to the phone!

Our model is the SCH-i535

You are obviously absolutley correct. I'm frantically trying to figure this out. I have flashed the stock rom and don't have super user anymore. The problem persists with the guys number.
Could he have flashed a custom kernel and modem or does reverting back using the stock rom cover all that ?

The one i linked covers all that and completely erases all data on the phone. Did you insert your sim after the stock flash?

I just double checked and I had the I535VRLAG1 version, yours is the I535VRALF2 in the link you posted trying this now. The crazy thing is that it even says that the sim is activated with MY number! but the calls are still comming from him. I even tried wiping the device and clearing the cache. I also tried to JUST flash the modem with VRLG1.modem.tar.md5 and nothing :\. Waiting on the file from your link to download and will try that.
Is it possible that this is being caused by something on Verizon's end? The phone ( with out the SIM ) is registered to him somehow? I know this is not normal but because his GF worked for Verizon could they have done something funky?

Yeah its definitely possible its from something she did to the phone but most likely nothing from Verizon's end. Does the IMEI number under status match the IMEI number under the battery?

Yes IMEI is the same in the OS as behind the battery.
The curious thing is that on the same screen in the OS where you find the IMEI there is also a field called Network and it says " Unknown"
It also has things like:
Eri v : 5
Mobile network type : EvDo-rev.a:8
The thing I keep coming back to is how is it possible for this phone to make calls\ have data with out a sim?
Starting to really think I got cheated

Cheated? Sounds like you have free Verizon service.
Roll with it. If you really want a bill you can have mine...

Just did and the same thing happened. I went to the Verizon store and the guy there had no idea and got me in touch with tech support from the store. They were dumbfounded and flat out said that what is happening is impossible. "It's impossible to make\receive phone calls with out a sim unless they are emergency" I harped on the fact that I am making phone calls as one of their other customers and that this is a big deal. In the end since I had the insurance and extended warranty they will ship me a new phone.

[Q] No service on new Nexus 5, but data works

Hi,
Just bought a brand new Nexus 5 from a person wanting to keep his iPhone.
Everything is working fine, except it says "No service" (sometimes with one bar, sometimes with all four). Data is working fine though, but neither SMS/MMS or phonecalls works. Sometimes, when i reset/reboot i doesn't say "No Service", but after one single phonecall it reverts back to "No Service" and only data works again.
Iv'e tried resetting with the firmware on the phone from the start, tried flashing both kot49h and krt16m, tried getting a new sim (which works fine in my old Nexus 3), tried different radio-settings but nothing works for me.
Any thought of, what I can do? (before I ship it off to repair, which would cost quite a lot)
Thanks, in advance!

You need to either update or add your APN for your provider, then everything will work for you. Flashing modems probably won't help you. Also, make sure the Sim card you have is active.

Don't want to look offensive, but are you on wifi?

Dansker her også
The problem you have, i faced that when my old phone got stolen. So less then a week ago my old phone got stolen (got it back, but bought a nexus 5 now :3) i called the insurance company and police to report it stolen, and i got it IMEI locked with the help of the police. And when that happends you wont be able to call or text from it, but your data will work for tracking it.
So my guess is that its a stolen phone and the original owner reported it stolen to the police, and now its IMEI locked.
Try and call the police and give them the IMEI number, and tell them what you told us and ask if its locked.
Great day to you!

@Zestia , I'll try that, although the websites with blacklist-lookup that I've tried the IMEI with, didn't say that it's stolen.

Did you check to see if your phone is blacklisted for being lost/stolen?

My IMEI numbers don't match and not registered on network

I have a SM-G920I, stock rom. When I dial *#06# an imei appears, it looks totally normal and its not blacklisted, but it doesnt match my imei on the back of the phone. It has not had a housing replacement or anything like that. In addition I cannot connect to my network, it says not registeres on network when I try to make a call and on my notification panel it says selected network not available. My sim does work on other phones.
I have thought that it might be a modem problem, but the imeis would still be different.
Plus, Ive thought of flashing xtrestolite and then exposed framework, then install exposed imei change.
Please help.

Hi, any advice you could give me?

"No Service" but SIMs detected and work on other phones

Essentially, my phone started reading "No service" even though I am at home where I normally get full bars. I chalked it up to a Visible issue, but the problem persisted even after several days and multiple restarts, so I put the SIM in my iPhone and it works great...
I then put a MInt Mobile SIM in the G7 Power and again "No service" but the SIM is detected because when one is not inserted it says No SIM but that goes away when I insert one, and I can read the ICCID in About Phone.
I tried a factory reset and even reflashed the most recent stock firmware using the the LMSA tool and no dice. Huge issue and don't even know why considering that my phone has always been stock. Could I actually be dealing with a hardware issue?

It looks like your G7 power is locked ....so " No service" as expected...
If it is unlocked , using manually network searching to see if it sees any network around you....
Or type "*#06" , if it still has IMEI.....

I don't think my phone is locked, as it was working fine on Visible for multiple weeks. Also, it's the Amazon edition and those are SIM unlocked. Do you mean some other type of lock?
Manually searching for a network results in it endlessly search for a network but never finding/listing any. Yes, *#06# results in the IMEI, MEID (HEX and DEC), and serial number being displayed.
I honestly think it's a hardware issue because I did flash the stock firmware using LMSA tool and that didn't help, but I do find that very hard to believe so I'm wondering if anyone has any other suggestions...

I honestly think it's a hardware issue because I did flash the stock firmware using LMSA tool and that didn't help, but I do find that very hard to believe so I'm wondering if anyone has any other suggestions...

I used Visible for about a year,
I stopped getting a signal at home, no network connection.
Figured out that I could get a signal in some other areas if I drove around.
Visible uses Verizon network and is owned by Verizon.
I had used Verizon for almost 20 years before switching so I have a good idea where it should work.
I suspect that Verizon has changed some frequencies from 4g to 5g or something.
I contacted Visible several times even got a new sim but just couldn't get a dependable connection.
So I switched to Pure Talk USA a AT&T mvno.
My issue seems a little different than yours but it could be related.

Essentially, my phone started reading "No service" even though I was at home where I normally get full bars. I chalked it up to a Visible issue, but the problem persisted even after several days and multiple restarts, so I put the SIM in my iPhone and it works great...
I then put a MInt Mobile SIM in the G7 Power and again "No service" but the SIM is detected because when one is not inserted it says No SIM but that goes away when I insert one, and I can read the ICCID in About Phone.
I tried a factory reset and even reflashed the most recent stock firmware using the the LMSA tool and no dice. Huge issue and don't even know why considering that my phone has always been stock. Could I actually be dealing with a hardware issue?

in the same boat currently with my g7 except i have service and use Verizon, but its extremely inconsistent. I also think its a hardware issue, but it only happened after I flashed a custom rom (Resurrection Remix). I don't think it's the custom rom though, as I went back to stock entirely and still the same issue. Haven't even owned my phone for over a year and its doing this.

What carrier u using now if ur on verizon that's the problem it don't like custom roms and which roms

I used LMSA to flash the latest stock firmware package: OCEAN_AMZ_QPO30.85_23_cid50_subsidy_DEFAULT_regulatory_DEFAULT_CFC.xml.zip
While I've flashed custom ROMs on tens of phones in the past, this is an Amazon version of the phone with a locked bootloader so it's always been stock.

This is very interesting, but I actually noticed this issue when I was about 35 miles from home, and persisted throughout my trip home - so I don't think that's the problem for me. I appreciate your response though!

I suppose it could be related. Mine phone worked continuously then stopped. Nothing intermittent like what you are describing.

I'm still using Visible, but on an old iPhone 6s Plus. I have a Mint Mobile SIM in the G7 Power for now - also says "No service" though I also have a perpetual unread voicemail notification with this Mint SIM inserted.

same here, it only stopped working after I flashed my third custom rom, I haven't been able to find a fix and I've dealt with this issue for around a month and it only gets worse. I hope it isn't hardware for you or me though.

Reflash the stock modems

I'm having a similar problem. I'm on the Verizon network. I get a "Mobile network is not available" message. I was running LineageOS 17, then switched to Resurrection Remix 8. I have the same problem with both ROMs. I have been trying to narrow down whether or not this is a hardware issue or software issue or a verizon blocking issue.
