Broken mobile network connection - Verizon Samsung Galaxy S 4

Ive spent days trying to solve this so I figured I would post something here and hope for a little assistance. After flashing a rom I noticed I had no mobile network connection when I tried to make phone calls or send texts but my lte connects and works and I cannot figure out how to restore my connection. I flashed back to my stock backup and rebuilt my nv data twice and I flashed my stock mdk tar and still have the same issue data works but calls and texts tell me "no signal found for mobile networks". If someone could give me some help it would definitely be pretty cool.

This happened to me once. It happened by flashing an AOSP rom that set CDMA subscription to NV by default. The only fix would be to flash a AOSP rom and then check network settings. Make sure RUIM/ SIM is selected in CDMA subsription and not NV. These network settings cant be changed on TW builds. Plus make sure CDMA/LTE/EVDO is selected. Hopefully this is what happened and solves your problem.
Edit: also make sure roaming is set to automatic.

Thank you so much that fixed everything, I've been using a RAZR for the past week while I tried to fix this and that was painful to say the least lol

Help! Cannot make calls or send sms

I flashed a custom ROM and after deciding I didn't like it I restored a factory stock ROM and every since all hell broke loose.
At first I had no connection of any kind whatsoever no matter what ROM or modem I flashed.
Then I dialed ##72786# and it seemed to have restored all connections.
Went to bed.
Woke up with only 3g working and nothing else. No calls and no sms.
Flashed a bunch of ROMS again including factory stock and no dice.
Spent 3 hours with Sprint Customer Service and they could not figure out why my phone cannot make calls or send sms. Kept activating and programming my phone with zero result
When making calls I would get "error 16" and the "your account could not be validated"
Please help! I am ready to sell this phone because I don't know what else to do.
Have you take it to sprint store?

I heard people having problems restoring a NANdroid from CM9. What version of CWM did you have? You tried a full odin restore? If so, try a return to stock odin restore with clear /esn checked in odin and see if that fixes it.
Update profile?

[Q] GS3 Network Problems

Hey Guys,
Have a rooted & unlocked GS3 I9300, running stock firmware.
When I first got it (Christmas) it worked perfectly. But after a few hours, I was unable to make calls (not registered on network error appears), go online or send/receive sms. I can now sporadically send and receive SMS, but it seems to be completely at random as to when I can do it.
When I turn the phone on and put in my pin, an error comes up saying I have entered my pin incorrectly, but my attempts left do not go down. 99% of the time, I have absolutely no service and occasionally, I have one bar.
I have checked and the IMEI code is still there and matching. Have tried numerous sim cards and none of them work.
Could anyone help me? At my wits' end!
Go to stock recovery and wipe data.
If it doesn't work flash a stock rom with Odin.

Tried that but made no difference!
Managed to get a full signal earlier, but it dropped a few minutes after. Could it be a hardware problem?

Go to your network settings under mobile networks, and do a manual selection of your network. Also try both gsm and hspda modes separately.

Tried changing between modes but none of them seem to make a difference!
When I try to scan for networks, it say "Error while scanning for networks".
Should I just give it up for lost at this stage?

Signal Problems and others

Hey guys, I'm getting an error code 65535 class 3 whenever I try to text, and a radio failed when I try to place a call. I'm running sense 5 (hatka) and I already confirmed that it's not the rom. Please help, I'm on a trip in new York so I really need this (this all randomly happened so I don't think I did this)

Make sure your on the right build (I.e gsm, global, etc.)

Yeah, I'm using the correct version. I checked and everything. Odd thing is that yesterday it was working just fine. I woke up this morning and my signal would drop in and out like crazy and I would go for about 3 minutes without signal before I'd get a bar (usually i have 3 to 5)
Here are some pictures (not sure if it would help or not)
(also I'm in New York on a trip so no laptop)

Either bad SIM (my first guess) or signal issues in the area (unlikely) hit up a store and swap out your SIM.

Re: Texting error
Hmm, I took out my sim and put it back in and it gave me full bars, I can get texts (rarely), and I can get very little Internet when connected (not wifi) I don't want to take my phone to Verizon because I'm running a custom rom and they'll see it and probably want to make me pay for a new one.

don't go by the bars....go by the dbm...whats that showing?
Re: Texting error
I'd run an RUU and see what it does, don't sweat the bars and if that doesn't fix it just give it a day or two. You can always run the RUU can call verizon and have them send you another SIM card.

When it spiked
Sent from my HTC6435LVW using xda app-developers app
According to both Verizon and HTC, there was a known issue with the phone software and not being able to read the SIM card. It happened to mine about ten times every week until an update was released to supposedly fix it in February. I still get the error from time to time, but far less than I did previously. If you've rooted and flashed a ROM prior to February, I would suggest making a backup and restoring the phone back to stock. Once you've done this, do the update to the new firmware and then reroot and restore from your backup. This should, I think, fix most SIM issues.

No data on Sense ROM, CM just fine.

I'll type more later I'm on the road but yeah basically I can't get mobile data turned on with any sense ROM I try. any aosp ROM works fine nice and quick. Sense won't let me configure apns and never connects. In phone status it says I'm on lte and not roaming but doesn't do anything. When I toggle mobile data it tries to turn on twice then just says disconnected. Idk what else to try. I need Bluetooth audio though cause I'm a trucker just going out over the road. Any suggestions welcome. Thanks in advance.

OK seriously wtf... Installed twice again now. First time was same as before. Wiped back to cm10 and data works fine. Wipe again and reinstall sense ROM (nos m7) again. Then said I was roaming. Wouldn't let me change APN settings at all. So I reboot. Then it says no service at all, please insert sim card. Reboot and restore my cm10? Everything works perfectly, back on 4g lte not roaming. Any input? What in the hell causes that? I'm so confused. It makes zero sense to me. I guess in just waiting on Bluetooth audio to get fixed I suppose.

@bigwilly90210 In the Sense rom. Have you tried changing to GSM and then back to CDMA/LTE in the mobile network settings?

Yes. It'll say preparing sim card then no signal. Then when I switch back to CDMA/lte it sometimes gets signal back and others says insert sim card and rebooting doesn't bring signal back I have to reinstall cm10. It really genuinely makes no sense. I've run sense ROMs just fine before, even custom ones since I got moonshined. I'm on the road and only have 4gb that i use for skyping the wife so I can't just download 1gb ROM files willy nilly to try you know? Ha.

@flyhalf if you could just get Bluetooth audio working on cm10 that would be more ideal... ha

OK seriously I've tried every sense ROM out there... I don't get home until next Monday so it looks like no Bluetooth for my until then. I'm assuming there's an ruu or something for stock out there? This is just bizarre

What PRL are you currently on?
Also, keep in mind that your PRL has to do with roaming, so it shouldn't have any bearing on sending text messages (unless you're roaming). Your issue could be with Sprint and their service in your area, and not with the phone itself.

The most current PRL is 25015.....fyi.
Also, the issue may not be on your end-it may lie with whoever is sending you texts.

If you get that error you can try updating first over WiFi. I'd also do a reboot first. Once that works you can call sprint and they will refresh your connection on their side.

There are usually many quick fixes for me when that happens, such as toggling airplane mode, rebooting, wiping and flashing my rom. One thing I've noticed is that having more than one sms app tends to make my messages not send, so if you have more than one messaging app I suggest deleting the non stock app and re-trying

I think I was having the same problems back on my Blackberry, Sprint had to reconfigure my service or something, I can't really remember. But if nothing you do with PRLs/Phone systems then contact them to see if they just need to re-provision your line or something along those lines.
So I ran an ruu today brought and now they're sending me a new one now I'm rocking and EVO
