It seems that everytime I plug my phone to the charger for few hours, it goes into Emergency calls only mode where I have no data and no calls incoming nor outgoing. Only way to solve it is to restart the phone or turn Airplane mode on and off to reset. Is this a common problem ? Could it have happened from unlocking my boot loader and rooting ?
I'm considering switching to the custom ROM "the base" in order to maybe solve this
Well I think this is new. Could just be a bad sim card. I don't have this problem and I haven't seen anyone else mention having it. I'd go to where ever I got it and have them swap the sim and if that didn't work the phone.
I would open the sd card/sim card cover and make sure sim is inserted fully. It should lock into place and need to be pushed in further to eject. I used a paperclip to push it in.

I actually had this happen to me like two days ago. I had just texted someone before walking to the lower level of a mall to go shopping. I took a look at my phone a little later and my phone was stuck on Emergency Calls with no data coming in. The carrier on the status bar wasn't even there anymore. Restarted my phone and all was fine. Not sure what caused it.
I've had this the last two days in areas I've always had great service. Wonder what's up with it.

Base rom has this enabled, or you need to be rooted and edit build prop.
I had this happen last week. I did the airplane mode toggle to clear it... but it freaked me out for a few minutes.
Running The Base, sk8r's kernel during install, no change to the LTE setting, no crazy mods applied.
I also sit in a nearly-dead-zone at work, and I have lost the data connection. Moving into the clear does not fix the issue. Reboot has been required.
This Android App Might Help
I had just the same problem with my Samsung Galaxy S2 with UK mobile provider Three.
I eventually wrote an app called which reconnects whenever it detects that the phone has got locked into Emergency Calls Only.

Figured it out for my phone
I got a refurbished LG optimus G E970 from a seller online and had this issue the second day of using it. I checked to see if it was the SIM or SD card by putting them into my old phone, but that wasn't it because the old phone still functioned properly making calls/messages. I even did a factory reset on the phone. Still didn't work. I finally just decided to change the mobile networks to my provider's GSM network and it worked. Not sure why it didn't work in the first place since I never changed the network, but this did the trick.

Hello. Could you please elaborate on how you fix that issue? I'm currently on T-mobile and my unlocked AT&T LG E980 is losing signal like crazy, just briefly loses signal and goes into emergency mode only. It is so annoying though. Would really appreciate any insight on it. Thanks.

So long story short, I opened a new line and swapped my hardware to the new line for the TB on my line. After I left BB, I called Verizon to do the swap. They said they couldn't because my SIM card was programmed for the original line and I had to go back to a VZW to get a new provisioned SIM, which I did. It worked when I left, but since late last night, I have no 4G or 3G. Any ideas what the issue could be?
Oh and when the phone goes into sleep mode and I awaken it, the 4G is lit up and then shortly after, no data.

when i first got my phone, the original 4g card wasnt working. turns out is was just bad... they swapped it for a new one and all is well. so i'm assuming u've already tried to reboot and see if that helps. maybe that card is bad as well? hmmm....u should go back to see if they can swap out to another one.
When I was in the store getting mine they were talking about how they'd been having allot of issues activating phone because of the large demand was causing a backup in the switch. There was a guy that walked in about 5 min before me and his would not activate, but then mine activated perfectly. So I guess it was intermittent. Makes me wonder if you got caught up in that backup when you activated the second sim.

Should I go back?
I would do a battery pull (pretty sure you've already done that) and remove and reseat the sim as well (if you haven't already) and if that doesn't work I'd reach out to Cust Service. May be something easily fixable in the system, save ya the time and gas of driving to the store.
maybe try a *228 and press 1 to program .... just a thought, I hate having to deal with customer service
I could be wrong but I thought *228 did not work with these phones because of the sim card.

My 4g would drop off randomly and I just assumed it was my area's LTE working out it's kinks. Then after doing the manual 3g only switch, the data was still randomly dropping off, so I was up to try anything out.
I pulled the battery and reseat the Sim like you said and so far so good...mind explaining that?, lol, doesnt make sense to me.

Wow, exact same experience I had yesterday. I went in late, like 5:00 PM. I had to wait a while for someone to actually help me, but once I said what phone I wanted it wasn't more than 20 minutes to get the transaction done.
Do NOT do *228.
I had this same problem today when activating my phone. Just call Verizon and they will walk you through getting it activated correctly.
Ironically, on my way to VZW it suddenly started working. LOL. "clog" in the system? I don't know, but it's fast as hell!
I don't have 4G in my area yet but I got the TB anyway. I love it. But the 3G does the same thing, just keeps dropping out.
This keeps happening to me also. Its very Frustrating. What the number to VZW Customer Service?

doesnt it still update the other radio? not everything uses lte.
No need for *228 because the sim card now is provisioned with auto PRL for when the phone does enter 3G service
DO NOT EVER ESN SWAP THE PHONE TO A NON 4G
Just like mentioned initially, the sim card and phone are designed for 4G lines only so swapping back to your old 3G device or onto another line is a bad idea.
If your trying to do an alternative upgrade and the store your at is full of morons, ask them if they could possibly do a Customer Provided Equipment Upgrade and then then ring out the phone in their point of sale system with the contract you have signed.
Until VZ Corporate figures out another way to do alternative upgrades, this is the only method I have found to get around this
Yes in many cases (including me) we have found it to take a while for 3G or 4G to stay on. Give it time. dial #832 to prove your phone can make calls and receive text messages. anywhere from 10 to some cases an hour before the phone is in full lock.
If your still having a problem go out for a walk or drive, heard switching between towers can help push the process.
I had the exact same problem as the OP, to fix it Verizon made me go back to best buy, you have to get the phone exchanged for a new one and then they have to call in to setup the new untouched TB on the line you want it on. Believe me it took 3 hours for them to finally fix it, and that's what did it.

Yesterday i had this problem too but today morning when i restarted my phone I got my phone registered to network seems like a carrier related issue. Try formatting your phone. And i also noticed that when the sim card was not placed correctly it showed me No sim card( i cut my sim using a scissor). So try placing your sim perfectly or try formatting your phone.

Hole volume up + middle key and switch on your phone. Your phone will get you into recovery mode from that menu using the volume rocker keys select format option and your phone will be hard reseted.

I had similar problems when my phone was delivered on Tuesday - cut my (Orange) SIM down to size, it worked for a while, then no network. Took it to an Orange shop, they tried their microSIMs, none worked. Arranged to have the phone replaced, but had another last play, and then my cut SIM in it started working - it would lose service intermittently, but eventually it was, and is, stable.
Mine has intermittent reception issues, ie dropping to emergency only every so often. My phone was sim-free so I figured it was because it lacks vodafone's customization.
I also cut my sim, maybe its an issue of it moving about slightly causing interrupts.

It seems that nobody knows exactly what is the fault, the part with the sim cut wrong ( it cannot be )... I have tried 2 different micro sim (factory cut) and still no difference... now I'm using my homemade the micro sim in my Galaxy S2 (without any adapters) and works perfect ( even moved around )... The Galaxy S3 is still not working! After checking with one of the guys from Phones4U, he told me that it can be a fault (hardware or software)... the best way to fix it... is replace the phone! I did not try any of the fixes from here ( so I will not make any changes to the phone - needed for the replacement - warranty )... if anyone has a good fix for this, just post it here for other people who are facing the same problem, thank you!
Your symptoms and what you've tried sounds so similar to what I had on Tuesday, also on Orange.
The guy in the Orange shop suggested to me that you'd see the same symptoms if the IMEI is reported as being lost/stolen - obviously my phone was brand new out of a sealed box, from Amazon, so this was unlikely, but it's an interesting thought if yours was second hand?
Have you managed to connect the phone via Wifi, and perform an update? This is what I did, on the off-chance it might help, as there was an update waiting. My phone did then intermittently connect to the mobile network, and gradually got more stable. It's fine now. Worth a try if you haven't already?
If your SIM card is not recognized, try this

Well, I got this problem too. And I found out that you have to push the card with a sharp object to the far left (when holding the phone with the SIM slot downwards, I shot it from the the opposite angle because of the light) inside the SIM slot for the phone to recognize your own made micro SIM. I used the SIM pin from a iPhone 4S, but I also tried with a needle and scissors, and they all worked fine.
As you can see in the picture, theres a "pin" sticking out the right (when holding the phone as described above the pin will be on the left side) Make sure that the pin "sticks out" as showed in the photo. It seems that if that pin isn't sticking out, the phone will not recognize that a SIM is inserted. I was trying for over an hour, and then I tried this and it worked at the first try.
Good advice, mistwalker, I also wondered if it was anything to do with whether it 'clicks' into position in the slot. Mine works now, so I'm not touching it again!
It has happened twice for me that it says it's not registered on network, both times i've held the power button down and deactivated the network then activated it again and it's been working.

Thank you for the advice, I have tried all so far... even updating the phone, in the last 2 hours I got stuck changing the position of the sim... I tried also a different sim... and same message comes on the screen! I will send it back to the seller and get a refund for it... the "funny" part is that I have moved the "micro sim" from S2 to S3 a few times, and the S2 has never let me down... with no micro sim adapter on it!
I think Galaxy S2 is still one of the best phones on the market... it is not so fragile as S3... and this is my second S3... the first one had to be replaced because a small accident (screen cracked after a bump in the wall)... and the bump was a light one. I admit is faster (like a "rocket"), but the "new" screen - gorilla glass 2 is fragile (like an egg)
Does anyone know how to check if the phone (IMEI) is on the blacklist? Maybe this is the "fault" from my S3... :cyclops:

Have you tried in gsm only mode? I have same problem and preparing SIM card issue doesn't come up in 2g mode. I was reading this kind of issue is produced most likely by a faulty 3g antenna.

I experience this problem frequently too. Not sure if there really is a fix for it. Toggling between airplane mode works for some people, reseating the SIM card, gently erasing the back of the sim card, applying 2 layers of tape to the sim card tray to keep the card seated appropriately, exchanging for a new SIM, putting phone into airplane phone and removing sim than replacing sim card, remove sim card than boot into recovery and clear cache and dalvik, etc.. yes I've tried most of these but to no avail. The OTA update may have helped a little I am not sure. Most believe it is a hardware issue that really can't be permanently fixed. If anything else is found let us know. Such an annoying problem that totally ruins this amazing phone.
There's different issues being discussed here. It sounds like you're having the issue where you need to toggle airplane or network sometimes when switching between networks or from WiFi to mobile data.
It's not device specific, there's some decent articles on it and in the early days we thought it was a Verizon issue. But it's actually a Sprint problem too I learned on accident when I was trolling their forums.
When the network is activated, on a device with a SIM card on Verizons network, the preparing SIM notification is actually describing a process very similar to *228 back in the olden days before LTE that was done when first activating a device on the CDMA network. The LTE network is different in that everytime it connects to the network is does that SIM activation process.
I know on my networks here, there's a changeover in one place it happens about 50 percent of the time.
If that's what is happening to you and toggling airplane fixes it, I think it's an LTE/network symptom and not due to a faulty device.
However I have a device I'm about to warranty with a hardware failure I'm thinking. It gets data great but absolutely no voice ever, never had an incoming call or anything. Or made an outgoing call in the month I've had it. It doesn't bother me I didn't buy this thing to talk on, but I'm donating the device so I'm going to have it fixed.
Anyway, from all the OP has posted so far, I'm not feeling like it's a hardware or device issue, however as more info develops that opinion may evolve.

U r the man Charlie. I am having an identical issue as op. And based on occurrences relevant to location it seems that this is only an issue when under 4g service-atleast for me-. Toggling airplane mode reactivates SIM as u said and restores full functionality. However, I have noticed the time needed to pass for said issue to reoccur is significantly shorter unless a full restart is preformed. If fastboot is enabled the issue persists. My question is this; if this is a network issue -which I'm sure it is at least in part- what software wise -if anything- could be going on a full restart fixes?

I'm a gsm user and I'm having the issue in a non 4g lte network. I have preparing SIM card every couple of minutes. If I toggle to gsm only mode everything is perfect, not even a single issue. Looking to the logcat, when the error comes up, it shows a message about ICCID number doesn't match stored one and then invalid radio technology. Is this software or hardware? I'm really confused. I've already tried everything from software side, kernels, radios, roms, RUU to stock.

Hi, I have read, looked, read even more and I have not found one thing to help me with this.
After I rooted and tried the recovery everything was fine till I powered off and restarted, now the phone powers on and I am able to connect to wifi networks but my phone is saying that it can not connect to any mobile networks and seeing as I haven't seen a way to go back to stock. I was wondering if anyone could help because I have literally lost all hope with this phone.

Well, you're technically still on stock - root/CWM recovery changes a few system files but nothing that should corrupt the basic stock install. You hadn't installed Titanium and uninstalled anything else - correct?
Under Settings->Software Information do you see a baseband version reported?
What do you have under Settings->Network ?
Try taking the battery out for 30s and taking the SIM and rubbing the gold contacts (light cleaning) on a cloth or your shirt. Replace everything and power up.

If your phone can see networks and you getting 'not allowed' messages, you likely have a SIM problem. check with your carrier.

I have same problem in LG Optimus L9.
I already replaced SIM from Vodafone last 15 days back and today i have the same problem. Vodafone help centre are telling to chaneg the sim again. Is this handset issue?
Same problem, not a SIM card problem
I have the exact same problem.
It's not related to the SIM card as my SIM card works fine in another phone and another SIM card in my phone gives the same problem.
This happened me 2 months ago, I left the phone for dead and started using a spare on I have, a couple of weeks later I check again and it's all working perfectly, strange !
Comforting to see that I'm not the only one with this problem.
I've done a hard reset and that made no difference.
So I have a Note 2 and a HTC one, for about three weeks I used my HTC one and then i switched back to my note 2. Yesterday I wanted to use my HTC one but every time I insert the sim card I get a no service message. what can I do to fix this?
I did not root the phone BTW.
Have you found a resolution? I just ran into the same problem. Phone was working great, then one Sunday afternoon it just stopped getting a signal. It's not the SIM as it works fine in my old SGSII (had to make SIM adapter). I am rooted and unlocked and running non stock recovery but still on stock kernel/radio. Haven't contacted HTC yet for obvious reasons.
I've had this happen a lot with my phone on tmobile. I live in a concrete basement apartment where there's no reception and if the phone goes more than 15 hours without any signal I almost always(80%ish) have to call tmobile and have them deactivate/reactivate the sim from their end.
A fix you can try that they swear "usually works" is go to settings/mobile data/network operators/search automatically
If that doesn't work then try settings/mobile data/access point names/menu/reset to default
Apparently these settings can be reset pretty easily when the phone doesn't connect to a network for a bit, but all this might just be a tmobile thing
I have a bit different problem - I bought HTC One from T-mobile and unlocked it. I tooked it with me to Europe and device does work with american sim (ATT and TMO) but it wont recognize any of my national carriers. Insterting simcards(perfectly working) does not give me reception or anything. Sim cards are the same thing in EU and US I think - also those are GSM phones. I have friends having same problems with their S4 from AT&T in Europe. Does anybody know something to help make this device work?
OP - this happened to my Wife's phone for no apparent reason one day. I simply removed & reinserted the SIM and rebooted a couple of times, hasn't had a problem since.

When I go into the settings to connect to the t mobile network, it says "your sim card is not authorized" or something like that. Maybe it's cuz I haven't paid my bill for 2 months? Lol but I don't think that's reason for them to block my sim :/

I had the same problem and I had to restart my phone sometimes several times a day, sometimes I had to remove the sim card enclosure and reinsert it in order for my phone to get a signal. So I contacted HTC and they told me that I probably had a defective sim card enclosure so they sent me a new one. After I installed the new sim card enclosure with the same sim card I had before the problem went away. I've been without any problems for the past four months or so since I got the replacement sim enclosure
type *#*#4636#*#* -> phone information -> make sure GSM/WCDMA/LTE Auto selected and Turn off radio
If you see turn on radio click that to turn on the radio. Is some cases the radio gets turned off and a reboot doesnt fix. This is the only way I know to recover it.
I've this same issue!
Did anybody found a solution?? I already tried everything... but seems like the phone is not blacklisted.. in case it is, something I can do? besides change my IMEI.
Thanks!!

Make sure your Apn is set up correctly. If you go to settings>Mobile Data>APN you can see your apn and compare it to other tmoblie ones

i bought htc one M7 in kenya but it shows no service when i insert the working sim. please guide me on this.
Radio chip
I wonder if anyone can help please. My M7 can't connect to the network. The radio isn't turned off, I checked using the code given by Shane_pcs, so I know it is a hardware problem. I suspect the radio chip has worked loose somehow and isn't making contact like it should. Any tips on how to resolve this please? I have seen a tear down of the M7, but don't know if anyone on here has attempted to secure the radio chip before...not even sure what the chip itself looks like. Any ideas please? Thank you.

I've had this happen a lot with my phone on tmobile. I live in a concrete basement apartment where there's no reception and if the phone goes more than 15 hours without any signal I almost always(80%ish) have to call tmobile and have them deactivate/reactivate the sim from their end.
A fix you can try that they swear "usually works" is go to settings/mobile data/network operators/search automatically
If that doesn't work then try settings/mobile data/access point names/menu/reset to default
Apparently these settings can be reset pretty easily when the phone doesn't connect to a network for a bit, but all this might just be a tmobile thing
