I've been struggling with a problem that I just solved in a stupid way so I'm posting to help other googlers.
As I was using my phone recently, I lost service like I had gone into an area devoid of towers, but service never came back. I verified that another TMobile phone (similar plan) found towers and service just fine. I tried everything I could think of from upgrading Cyanogenmod and the radio to reverting to the stock firmware. No matter what I did, the phone would not get signal. When I went to Settings -> Wireless & networks -> Mobile networks -> Network operators I would simply get "Error while searching for networks".
It turns out that the SIM card had seen the end of its days. I went to the TMobile store and had the SIM card switched out for a new one (free) and everything worked again.
The explanation I was given was that old "legacy" SIM cards sometimes will just stop allowing you to connect to the towers with no other symptoms.
TL;DR: If your TMobile (maybe other carriers too) phone isn't connecting to the towers anymore, don't panic. You probably need a new SIM card and you can probably get one for free.
Seeing the exact same problem in the last few days
Found your post by googling the error message - I've got the exact same situation on my G2, the behavior started this last weekend. The phone sometimes connects but is very, very inconsistent. I'm missing almost all text messages, or getting them up to a day late. I guess it's off to a t-mo store for a new SIM card if this doesn't stop. Funny thing is this phone was purchased with a (supposedly) new SIM card - hard to call it "legacy".
Thank you, I just stopped getting service today randomly and nothing I did could get it back. I went in to panic mode and was flashing and wiping and everything I could think of then I saw this post. I didn't think it could work but sure enough it did.
way to be....i learned my fact for the day.
mine just bit the dust.
called t-mobile and they suggested a new SIM as well.
ah well
I had the same issue and after doing tons of troubleshooting i seen that there was a space right under the keyboard that was fully flush with the phone. I lightly pressed until both sides snapped back into place and full service returned. So if you have this issue check to see if there are any spaces open and snap it closed.

Mine has been doing this sporadically, it comes and goes and sometimes I cannot get it to find a service provider. I have to keep doing it over and over and over. Sometimes I have to set phone down and come back in a few minutes to do it again and it finally shows a provider.
The question I have is if you take your phone into Tmobile store to have sim. card replaced do you have to revert phone back to stock G2? Will they say something to you if you are rooted and running CM?
This problem happened to me too and a SIM swap fixed it. They don't check if you are rooted- they might ask you to reboot and change some settings to rule out the obvious stuff like airplane mode, correct carrier, etc.
Maybe not same issue, but also have a soultion for similar issue on G2X
Maybe I didn't have the exact same issue, but I had the exact same symptoms, so throwing my solution up here for other Googlers trying to troubleshoot this as well...
I actually have a G2X, went to Canada where I disabled roaming data and used the t-Mobile wifi calling stuff primarily...
When I got back home to the USA, I couldn't get a signal, but I also didn't have the little x next to the icon... When I went into my settings, I couldn't seem to get the "Use 2G Network" setting to stay off, and of course I couldn't make calls or anything over the mobile network...
So I figured I just needed to force the phone to register on the local network, maybe all the roaming got it mixed up or something, but when I went to the "Network operators" setting, I couldn't "Search Networks" and "Select Automatically" didn't work either, I kept seeing the error "Error while searching for networks".... spent some time playing with libril.so and friends, but it made no difference.
Anyway, long story short, it turns out that there's a setting in the T-Mobile "Wifi Calling" app under "Connection preferences", if you select "Wifi Only", it applies to your setting all the time, even when wifi is disabled, disconnected, and even if the "Wifi Calling" app is disabled too !! So just change that setting back to something else when you're done requiring that behavior and everything will work again, Yay!

I can verify that this is the solution that works. I have the LG G2 w/ T-Mobile. I hadn't had any problems until today. Stumbled upon this thread after the T-Mobile chat support couldn't help me. Went to System Settings and turned wifi calling off completely. Back in business.
Since 2 nights ago (and after 3 months of perfectly operating), my 3G network suddenly stopped working, and I haven't been able to reconnect to it. I can only use 2G (GSM) network.
I thought it might be a hardware issue, but when I search for 3G networks, it actually finds my operator's 3G. When I try to connect to it, it says "Registering on DIGITEL" then "your sim card does not allow a connection to this network". I tried with 3 more sim cards and nothing. If I select "WCDMA ONLY", it instantly says in the status bar "Selected Network (DIGITEL) unavailable".
I did a factory data reset (through menu), nothing. Then a Hard Reset through PC Companion, nothing. I tried turning flight mode off and on, and even turned off and on the radio from the "Phone Information" menu and nothing.
I called to my operator but they claim to see no problem (they're always terrible and useless).
I read somewhere about flashing the radio or something like that! Does anybody knows about this? Any help please?
I have a LT15i running 2.3.3 Built 3.0.1.A.0.145
Baseband version: 7X30A-AAABQMAZM-1290_21-22
Hi Guys,
So, I've been using the GNex for about a month. I moved to this phone from a Moto Atrix and here is what I have noticed and have looked around but didn't see any good answers to these questions I am having. Hopefully I get some answers here.
Device info:
GNex GSM version on ATT.
Running JB 4.1.1 Stock with Trinity Kernel (rooted and bootloader unlocked).
Issue #1: I get really bad reception at work. But, when I leave the building, my phone doesn't automaticaly connect back to the network. Sometimes, if I don't check my phone, it's been like that all night long until the next day when I have tried to make a call and it said "No Network Available" and I have to either reboot or toggle airplane mode to get back on the network. Am I missing something? In my past experience with other devices, they try to automatically connect back to the network when they loose connectivity. Also, if I get in an elevator during a call and the call gets dropped due to network unavailability, it doesn't connect back to the network and I have to toggle airplane mode. Has anyone else had this issue?
Issue#2: This is with the stock mail app. Specifically the search in this mail app. No matter what, it always returns zero results. Has anyone had this issue with the Mail App? If I use the Gmail app, it works fine. That's what I am using now, but am curious as to what I may be missing that make it not return any search results in the stock mail app.
Q3: Speed Dial: How do you set speed dial on the dialer? Is it even supported?
thanks in advance,
vG

it could be to do with your radio, what version is it? baseband version in about phone. im no expert but when i flashed a jellybean rom i had to update my radio afterwards cause my signal was dropping alot. i also had the same problem later on but that was down to my network operator. before i realised it was them i googled my problem and a few forums suggested that my sim card was goosed. so maybe check those three possibilities? i cant help with the other two issues unfortunately but good luck sorting it out!

Hi,
*Message edited now that I've done more testing *
Got a weird problem with mobile data on my Z1C:
If I'm on the cell network with no wifi, I don't get any notifications for Gmail, WhatsApp etc. As soon as I reconnect to wifi a bunch of notifications flood in. Data and notifications work normally on wifi and in an open app. I have a 2GB data plan and use <20% of this.
The exact same thing happens with my Vodafone UK SIM and Asda (EE) PAYG SIM, and when booted into Safe Mode.
Restrict Background Data is NOT set - neither the global setting nor the app-specific setting. "Set mobile data limit" is NOT set.
If I put either SIM into a different device, I receive my notifications fine.
I have tried re-downloading my Internet Settings from the "wireless and networks" screen and messed about with the Voda APN - followed Voda's online instructions and found some alternative ones online (e..g use the Internet APN rather than WAP one) but no change.
I used this phone successfully on O2 for two years and never had any trouble with data. I have recently (after leaving O2) rebuilt the phone to install new power flex and new screen - might that be related? I saw a post from someone who said his Z1C data connection keeps dropping and the only way to bring it back is to reseat the SIM multiple times.
The device isn't rooted and has never had Greenify installed.
I'm on KitKat.
Any suggestions please?
Update:
I never found a fix to this so ended up doing a factory data reset, which fixed the problem.
I have an unlocked HTC One with a venom Rom. I have been using it for a number of years and am happy with it. I used a different phone for the last few months then went back to this HTC. Now, when I connect to wifi I get an invalid sim Er05 notification that comes up and I cannot get rid of it by swiping or any other means. When I press on it WFCService is displayed. Wifi Calling is not available to me. This is a Canadian phone but I think the carrier was Wind or someone who might have got their phones from T-Mobile.
I have read a lost of posts on this and the suggestion is to turn off wifi calling. When I try to do it, the box for it is unchecked and wifi calling is marked as disabled. I cannot check the box to enable it.
If I disconnect from wifi the notification disappears, but if I reconnect the notification reappears and can't be removed. I have tried reinserting the sim but it appears that this is a t-mobile feature and you need a proper t-mobile sim or you will get this error. But I have been using this phone for years and not seen it before. I have tried deleting the wifi calling service, but it recreates when the phone reboots. I have reinstalled Venom twice and cleared the cache and dalvik and that does nothing to help. I have booted in safe mode and still the notification appears. I would like to delete wifi calling permanently but do not seem to be able to.
Does anyone have any thoughts on this. The phone is rooted.
I flashed a backup from a few months ago and the problem is resolved. This means it was not the sim card or anything related to the phone. The only changes that I know were made to the phone were that I added three apps. Advanced task killer (I think this is the one that started the issue) Amazon and Grace Remote. I think one of these likely caused the wifi calling to activate even though it was disabled.
Of note is that I no longer have a wifi calling option at all in my settings. It is not there at all. Instead there is an "Internet Calling" option that cant be turned off but can be set to internet or internet and data.
Something glitched and I think it was one of the apps I used. Likely advanced task manager, but perhaps it was grace remote(an app to control my internet radio remotely). I doubt it was the amazon app.
