[Q] My phone will not roam. Grrrr.... - Verizon Samsung Galaxy S III

Verizon SGS3. Running CM 10.1, last nightly (not 10.2).
I'm in Canada and my phone will not connect to a network of any kind. My wife's Iphone connects, so it's not a Verizon issue. When I go to phone status it just tells me "Searching for service" under network, and mobile network state is "disconnected".
I have "Automatic" selected under System Select, and my Network Mode ls "LTE/CDMA/EvDo". I've tried changing all of this and it just won't find a network here, I mean no cell service (no data either, but that's not crucial for me). I feel like roaming is just turned off and I can't turn it back on.
Any help would be appreciated.

Thanks for the reply. Yes, I do. My IMEI is intact, as is my phone number.
I should add that I was unable to make this phone work as a GSM phone in the UK, had the same issue (no cellular reception), I don't know if that's related or not. I also tried to use some Nandroid backups I had going back as early as Feb of this year and still no go.

I just got this phone a few days ago and so I don't really know this phone that well. Maybe someone will chime in.

After doing a complete wipe & odin back to factory it still didn't work.
Back on cm10.1.2 now &I used the "phone info" app to select PCS (1900mhz) band. My phone immediately picked up the cell network. No data, but I'll take it! For some reason being on the multi band labeled USA wasn't getting me anything & my phone wouldn't auto-select. Not sure if it's a bad sim card or what.

Able to use 3G only without physical SIM card? Network debug menu?

Is there a way to use the phone without a SIM card? I don't have LTE in my area, and I keep getting the "no SIM Error" so was thinking that the SIM was useless anyways.
On the stock ROM every time I get the SIM error, or if I remove the SIM card itself, I get no data on the phone at all. When I try to turn on Mobile Data it prompts me to insert the SIM.
On other CUSTOM or JB ROMs, I don't get the SIM error prompt but I simply get no data.
On older Sprint phones, I know you can go into the DEBUG menu to see that EVDO/3G was actually being authenticated, the handshake was negotiated, then connection type/speed/tower/hand-off status, etc. Is there such an option with Verizon phones? I'm wondering if Data is completely shut off without the SIM, or if the data connection is actually established on the network but simply blocked from being used?
PS - per recommendation I have tried using the PHONE INFO app to switch the option to NV only, but am still getting no data. Voice/Text work perfectly.

ASFAIK, the SIM does 3g and 4g. WHY? because 3g on the gs3 is ehrdp and that also requires a handshake between 3g and lte. I believe it is like using 3g tech but with the pipeline size of lte... or thats as far as I've read into it.

Thanks for the info, xicewallx. I was afraid of that, however I've read of people flashing both Sprint and Verizon variants of the SGS3 to Boost, Straight Talk (CDMA), Verizon Pre-Paid which all I assume do not use LTE/SIM. I presume this means that the SGS3 can certainly use 3G without the need of the SIM card. I'm looking for a way to default to this on the SGS3 for us poor folk who do not have the luxury of LTE yet and have to deal with the SIM error until Verizon/Samsung fixes it.
Any help would be greatly appreciated!
I was able to get to a debug screen using the IOTHiddenMenu option (through Any Cut) but it simply stated that EVDO was in "sleep state." I wasn't able to figure out how to get it to start a connection yet.

So get a new phone? That one is obviously faulty. Go get a free replacement. You have to live with it for 2 years. I wouldn't want a faulty device for a week let alone 2 years.

Are you in a poor signal area? Only time I've received the "No Sim" error was at my parents where the signal is crap. As for using it without the sim card, doubt that's possible since the sim is used for authentication if I'm not mistaken.
hello,
if i understand correctly, the sim card in the S3 is basically the same as all the previous world phones, meaning its just RUIM card. The MEID and IMEI are on the phone, the card it comes with is just basically a storage device in simple terms. can someone who has access to another verizon active S3 sim try putting the card into their phone and checking the IMEI that the phone reports? does swapping the cards change the IMEI in other words. I do not think it will, but interested to know for sure.
i just started playing with one of these, but i feel realy confident you can get non 4G services to work without a sim in it.

You have it just about backwords. The sim is the real identifier on vzw 4g devices. You can take a working authorized sim and use it to activate another 4g Verizon phone and it will activate under the phone number associated with the sim.

There is still an ESN /MEID that the network uses to identify the phone for the CDMA side of the network. The process is all handled by the LTE SIM on LTE phones, though.
OP: You have a broken phone. The no-SIM error is not something that goes away. Take it to a store and get a new SIM and/or order a replacement.

im gonna have to dig in some more i am still not convinced the card is not a ruim card. like the other sprint and verizon world fones the imea is in the fone im pretty sure, until you instroduce another networks actual gsm card. i still the card it comes with is a simple ruim that holds the login info and other data, etc, well you know what ruim is.
does anyone have a service manual or white papers on this one yet? i would love to read through them.

I'm still looking for an answer to this if anyone has any suggestions. Any way to get 3G without a SIM card?
Did you ever get a new phone from Verizon? It seems like an issue with your phone, not the network.
I have been trying something similar along the way as I have been able to get rock solid data by switching to EvDo only using the Phone Info app.
I gave determined I am connecting to a US Cellular tower when I have solid data.
But while in EvDo only I cannot send or receive calls or texts.
I am looking for a way to enable calls and text while in EvDo only mode.
Not trying to highjack just thought this is somewhat related.

New phone and new SIM from Verizon seems to have made the problem less apparent, but it still happens, especially when driving through areas where reception is a bit spotty. It's really become an issue as I rely on getting emails for business, especially while traveling, and I don't get notifications of new emails if I have no data service which I don't become aware of until I actually look at the phone. Missed a couple of important emails/meeting invites because of this already...

I flashed a VZW GS3 to Sprint. 3G data is working fine w/o a SIM card. If I put a non activated VZW card, data doesn't work obviously.
The trick in getting this to work is to use QPST to configure Profile 0 and Profile 1. When flashing to Sprint or Boost, you must also load a Sprint PRL into the device using QPST.

[Q] Network connection cuts out - Not registered on network

I have read a few threads about this issue, but none of them seem to be the same exact problem..
Right now I am running ParanoidAndroid 2.15 with InstigatorX 6.3.6 kernel.
When I first noticed the problem I was on PA 2.13/IX 6.3.6 I believe and I was using the UCLF6 modem.
My network connection was fine until one day I noticed that I had 0 connectivity and when I tried to make a phone call it said I wasn't registered on the network.
Sooo the issue..
My network connection constantly shows that I am not connected to the ATT network, sometimes the network is out for a good 5 minutes or so before it connects to it again. When it does connect to the network it usually shows up as connected to the Edge network..once in a while it will show 3g; I used to have full bars of 4g/hspa.
After a few minutes go by, the network connection cuts off and I am again once disconnected from the network.
From the time I had no problem with my connection to when it started disconnecting from the network I have no idea what happened.
Yes, I do flash ROMs a lot, but this seemed to happen over night. (I had not messed with my ROM for a good while and then BAM my network blows 'all of a sudden')
Things I have tried..
I have tried different roms, different modems, I have tried the whole airplane mode deal, tried pulling the batter, I have reverted back to stock using Odin and the stock ROM file. My IMEI number shows up correctly, my settings are default as far as allowing data connections ect.
I am not sure if there is anything I can do besides call up the warranty department and try and get a new phone, but I wanted to ask here before I did that.. I've already returned my phone like 2 or 3 times since February lol.
Try getting a new SIM card from AT&T. There is a $10 fee for it, but I had a similar problem and this fixed it for me. My phone would lose service and say "No SIM card inserted" then I would hit restart and everything would work except phone calls. I had to remove the SIM for a few minutes and put it back in in order to make or receive calls.

Not sure if this will help or not, but in the past I have had AT&T "re-initialize" my phone on their end and it has fixed some connectivity issues.

Backup and odin back to stock I727UCLF6 and see if the problem goes away. If yes then its possible you need to look for the AT&T LTE APN settings.

I've tried using Odin to stock ICS and also GB, but the problem still occurs =\
Did you unlock it?
Hey,
Did you unlock the phone? I have a similar issue, having had tried many different modems kernels and ROMs including the stock ones. It turns out that if the phone is unlocked then it will lose connectivity to lte and 3g. I get edge sometimes and one bar max but I cannot make a call out ever.
Unlocked it as I was travelling in the states and now Roger's says I voided my warranty by unlocking it. Tried a different sim card but I am only able to text right now, no calls. The only silver lining is the big three are starting to lower their prices a bit to compete with new competitors.Then again they make budget brands like koodo and public mobile to directly compete with the new entrants so unless the crtc steps in looks like we'll always get gouged.

I'm not 100%, but I don't have any warnings about my SIM card or anything
Same boat
I'm having the same issue with my Galaxy Note 717r on Canadian carriers Rogers and Telus
I keep getting the Error 'Not registered on Network'
On Rogers, if I select GSM only, it will register on the Network and connect with EDGE speeds
It has been Carrier unlocked at some point but it was working that way for a while. You can check by using this service code: *#7465625#
Tried multiple SIM cards that work with other phones.
Verified that the IMEI number matches what is on the sticker *#06# Rogers told me if I can make calls on the GSM network than the IMEI isn't blocked. Don't know if that's true but it makes sense.
Went back to stock everything (Modem, CSC, ROM) then I upgraded to ICS OTA.
Enable SIM lock, Disabled SIM lock.
How do you know that carrier unlocking blocks you on the 3G/LTE networks? Can the carrier be relocked?
I've got another 717r coming to me. I think I'll try backing up the EFS folder and restoring it on this phone just to verify it's not corrupt or a blocked IMEI.

I'm not sure about that one.
But what ROM do you use? It seems like this only happens with people who have JB ROMs..it looks like..
I just called ATT , they did some kind of wireless number reset, nothing happened.
They are going to send me a new SIM card which I can test and see if that fixes the problem, but I'm not going to hold my breath though.

Nexus 5 was on R+ CDMA - Now ST SIM gives no signal

When I go into the settings for Mobile networks at the bottom where it says System select it says change the CDMA roaming mode. the problem is I reset the phone and it now has a ST AT&T SIM card in it. Why does it still think it is CDMA?

Same exact thing happened to me. When I was researching the problem I came across this thread. The phone was showing no signal and then suddenly it received a SMS message saying my phone was ready to use. I rebooted it and it's fine, full signal. To people experiencing this, I suggesting waiting for about an hour and maybe your phone will cure itself too.

Signal/Network problem

Hi guys,
I've been having this problem with my N5.
Its a d820 model, unlocked and rooted.
I have no signal, cant register to the network either.
I can use wifi with no problem too.
I changed the micro sim card with other carriers, same issue. I asked for a new micro sim to my carrier too (not cut), but still getting the same problem.
It's worth mentioning that the micro sim works flawlessly. Im using it everyday on an HTC One S and signal and data works perfectly.
When I first get the simcard on the N5, it asks for a reboot, after it comes back up, it shows strong signal, but I can't make any call or receive, no messages either.
After a few minutes, the signal goes down and it shows only emergency calls.
Going into mobile networks and searching for my carrier takes quite some time, but no matter how many times I try to select my carrier,it always comes back with not able to register in the network.
I did a factory reset, and went back to stock, and then performed the system updates to 4.4.4.
I flashed a couple of radios as well, but no luck.
The IMEI shows well, and its the same that shows on the box, so I guess no problems there with a corrupt IMEI.
Has anyone else had any problem like this? Any suggestions?
I've been reading some threads here, and I still have to try a different kernel/ROM, but if anyone else knows of a similar situation, I would appreciate any suggestions.
May be it has something to do wid preferred network...
If u use 3g go to dialpad
Type
*#*#4636#*#* phone info
Select modem as wcdma only...
If u use lte select lte only... See if this works
I think I already tried that, but cant remember for sure
Will give it a shot, thanks
Is the phone second hand?
Have you checked if the IMEI is blocked by the network?
sounds like you bought a used phone that has been blacklisted. if blacklisted, your phone wont work on any US carrier, and many Canadian carriers.
Yes its a second hand phone, and I don't know if it is blacklisted on USA, but Im in South America, so that shouldnt be a problem
And there are no carriers here working with N5 so they cant blacklist the IMEI either
(This doesnt mean that the phone doesnt work here, actually, my wife has another N5 that works like a charm here)

the carriers dont have to work with the n5 to blacklist it. in other words, they can blacklist any phone that connects to their network. as soon as you connect to the network, they know your imei and other info about your phone. anyways, they blacklist your imei, so when your phone tries to connect, it cant. the agreement that carriers have in the US and Canada, could possibly be for all of the americas, or, in south america, they could have their own blacklist.

googling, i found that carriers worldwide are sharing blacklists.
The GSMA, an international association of wireless carriers, also keeps a database that wireless carriers worldwide could check to prevent stolen phones from being reactivated on their networks.

Well I just checked. IMEI not blacklisted on my carrier, also checked with swappa, not blacklisted either.
I used the *#*#4636#*#* to select wcdma as well as other options there, but still no go.
Also, under Mobile network settings, changed the preferred network type to LTE, 3G and 2G, but no luck
Tried Choose automatically the network, but still getting the message that its unable to register to the network right now and that I should try again later
I guess Im left with flashing some other ROM/kernel to see if it helps, unless someone has any other suggestions

I don't know if the problem is with the carrier, since I'm using the very same simcard with another phone and I have data and network with no problem.
The phone is d820, but I know it works here (my wife has the same one), network 2g and 3g work well here, LTE is the only thing that won't work here with this phone but I don't care about that

If the problem is wid radio flashing a different rom won't matter ..
Have u tried flashing a factory image ?
I know flashing a new ROM wont help with radio, but I've seen that using *#*#4636#*#*, going into phone information and then Select Radio Band, gives me an error and force closes.
I've seen some threads about that, and someone saying that it was working on a CM ROM, so I was thinking of trying that in order to be able to select the radio band and see if that helps.
About the factory image, yes, I used the google images to go back to stock, and then performed the system updates.
Well I flashed Slim Rom, and was able to get into *#*#4636#*#* to change radio band. Tried them all, no change.
Played around with the preferred networks and no luck either.
I'm officially out of ideas, but I'll keep digging around to see what I can find.
Any suggestions welcome.
Also, I know that there is a known issue with the GPS signal on some Nexus 5, and there are a few videos on Youtube showing how to fix it (basically opening the back of the phone, and sticking a piece of paper under the connector).
Does anyone know if there is something similar happening with the radio? Does anyone have a photo of the phone showing which part would be the antenna?
One additional thing I noticed.
If I switch, or just take out and reinsert the micro sim, the phone asks for a reboot. After doing that, when the phone boots up, I see I have network (full bars), going into mobile operators, I can see my carrier, and I can register too. But I cant make or receive any calls or messages.
During this 10 minutes that I have this sort of fake signal, if I go into *#*#4636#*#* and phone info, I can see my carrier, but it doesn't show my phone number. Weird.
Lg nexus 5 network issue
i am facing the same issue with exus 5 .In my hometown in India,the phone simply shows "Emergency calls only" and shifts to normal working mode with full network coverage once i travel to other parts of my state (parts which probably has a better signal strength ,i dont know ).i have tried out changing the sim card and a factory data reset ..Both didnt help ..

I've been reading some threads here, and I still have to try a different kernel/ROM, but if anyone else knows of a similar situation, I would appreciate any suggestions.

Has anyone been able to track down the issue and get it resolved? I'm facing the same situation, and almost taking it to an authorized LG support so that they can change the motherboard.

[Q] Taking a Verizon S3 to AT&T

I bought a house and moved.
No service in the house with Verizon.
So, I switched to AT&T.
AT&T told me I would get HSPA+ with my Verizon S3.
Well... I have 2G, voice, and text.
Anyone have an idea of how to get HSPA+ enabled? Is it possible?
I have a custom ROM, but I can flash anything if it would help.
I don't think it's possible, they run on completely different networks (CDMA Vs GSM) and the phones radios are built accordingly.

I'm leaning toward that. Guess I'll upgrade....
Verizon to AT&T and SIM unlock with NO codes

There is a way cant remember where i read it, maybe on the t-mobile forum. I recently bricked my att device and came across a verizon variant and was able to use it for att with out having it sim unlocked just a few hours ago steps taken were as follows:
After swapping the motherboards i factory reset the non rooted verizon device from the settings menu as I was just going to sell it on ebay. I had been using wifi only on a sim locked t-mobile device but the camera was not working so i switched back to the verizon and was prompted to complete the set up after i booted the device with no sim card inside. I got the no sim card message and ran the app Region Lock Away that has a red circle icon and a black unlocked pad lock by chainfire. I was skeptical 1 for the device not being rooted but tried anyway. The app said it was not able to verfiy root and closed; however once I inserted my att sim card without powering off the device i saw signal bars. Now Im not sure the app actually did anything and I might have tried the app before resetting it without success but after checking the network mode in the mobile networks tab it now shows Global as the preferred network. So i started texting people and then calling all with success. Now im still on the edge network and this may not solve your issue but I remember seeing the work around I think it has to do with correcting the APN settings but there is always a way to get things done. Keep looking you will find it. Im just happy to have cell service again but Ill be looking for the thread in a day or so as well.
Forced into an AT&T phone. It worked for 4 days then stopped. Their tech support claims the tap wasn't compatible and they don't know why it worked
I had 2g for those 4 days
I'm always on wifi but noticed my data wasn't working so not an ideal switch but if you are in a bind it does work. I'm still running at&t network on this Verizon motherboard just fine

I don't know what happened but all inbound calls on day 4 went direct to voicemail. I reset phone, flashed different ROM.... Nothing
