[Q] Limited Service, Emergency Calls Only - No Signal

Hello all!
I've made some searches, but I could not find a resolution to my problem (and very few people seem to have this problem!).
Sometimes, in Android only, my phone will drop signal to zero. This most often happens when coming out of sleep, but it happens sometimes when I'm just holding it, too.
I'm thinking that it most often happens when it switches from HSDPA to EDGE or from EDGE to HSDPA or when it gets a particularly strong cell signal (rarely, though; I'm on T-Mobile USA).
I've read about PPP drops, but I don't think this is the same--in my case, the signal just goes to nothing. It's like I'm in a basement. No voice calls, no SMSes.
Once, I was able to get to the choose-a-network-screen; there, I chose T-Mobile, and it told me that the SIM was not the correct one for the network. Other times, I've gotten to that screen and T-Mobile could be chosen. Another time, it'll give me an "error when searching for networks."
Does anyone have any suggestions for this?
Thanks!
Edit: I thought I'd clarify; this happens across every Android build. I've tried 15 and 14 radios. The Europeans seem to have this too: http://forum.xda-developers.com/showthread.php?t=796713 ... Is there a solution for this? Thanks!

Have you tried using secret setting to get onto phone options and change cdma preferred to gsm auto prl. I used to have this problem too. Dial *#*# 4636#*#* to get to those settings or download free app "secret phone setting" from market. Hope this helps.

Hi,
Thanks for your input! Unfortunately, I think this disables 3G in general as well... do you know of a workaround that still lets me keep 3G?
Thanks!
Edit: My apologies; other solutions that have mentioned GSM seem to think that it keeps it at 2G. Looks like this might work, even for 3G! I'll keep y'all updated. Thanks again!

How does this work for you?
I have ths same problem, and I can't get the 3G to work regardless of all the setting.
Also tried the secret setting.
Still limited service
Using tmobile usa, t-zones, rafdroid 3.0
Was okay and slightly on and off intermittently until yesterday, totally lost connection.
Please help

Hi,
Did anyone here able to resolve the problem? I have exactly the same problem. I am on T-Mobile US (HTC sensation 4G), my phone has stopped picking up any signal. It always shows "limited service/no signal". T-Mobile customer center is saying that there is no issue of signal strength in my area. In the phone, under wireless and netwoks setting, I am unable to check "mobile network" option too. I did factory reset too but thats also not working. I have also contacted T-Mobile and tried using the settings they provided for APNs but that did not work too?
I tried searching at various places but no one seems to have faced this issue. Any help on this issue would be appreciated.
Thanks in advance.

Limited Service, Emergency Calls Only - No Signal
Our HTC HD2 is showing Limited Service, Emergency calls only.
We are running Android From NAND by aMAGLDR V1. 11 build DEC 31 2010 Cotulla 2010. The Limited Service, Emergency calls only began today
at 9am and the issue hasn't been resolved.
Is there any step by step suggestions?
Changed secret settings WCDMA to
GSM auto (PRL) with no resolution.
Would a hard reboot resolve this issue? How is a step by step hard reboot performed on the HTC HD2?
Thanks in advance.....

First step tho I'm sure you tried this already would be to reseat the sim card, followed by testing the sim in another phone, then another sim in the hd2.

When T-Mobile opens we will install new SIM.
The HTC HD2 is new so have no idea if the issue is
any of the above you listed. T-Mobile has the best service plans
but the worst customer service.
We require a true unlimited plan because 90% of our calls are
to landlines.
Thanks for your response.

Required sim card upgrade!
7 NOV 2011 UPDATE ON LIMITED SERVICE, EMERGENCY CALLS ONLY!
Visited a T-MOBILE store and the SIM card was 2G and they upgraded
the SIM card. It resolved the issue.
We thank everyone who contributed to this issue.
T-MOBILE representative stated the HTC HD2 could never achieve
4G. Attempted to upgrade us to a Galaxy 4GS II. We will never
pay retail for a phone.

Network Mode
I had this issue as well on my HTC Sensation. What worked for me was to set Network Mode to "GSM Only" (Settings/Wireless & Networks/Mobile Networks/Network Mode).
It was weird, when I had 4 bars I could make/receive calls, but when reception was 2-3 bars it wouldn't. It has been less than 24 hrs so not completely sure the problem has gone away but worth a shot.
Bonne chance.

My solution
Hey Guys!
I had the same problem after upgrading my Moto Milestone 2 to 2.3.6 Vivo ROM. When I went to class at university I had "Emergency calls only" - not "limited service" or "no service". So I had receiption... Also I could select any other provider but not my own (T-Mobile Hungary). The same thing happened when I was at home, in the house. The strange thing was that I didn't have any problem at any other place. Also, when I locked my screen and didn't use the phone, I had bars and could receive calls&sms, but after waking up the phone, the bars went down to 0 and got the "Emergency calls only" message.
I Googled a bit and found an answer which was worth a try before asking for a new SIM card from my provider ('cause that was the only solution I found in every other forum).
So the things to do are:
dial *#*#4636#*#*
go to Phone information
Scroll down to "Set preferred network type"
Select "GSM auto (PRL)"
My default was "GSM only" and after setting to auto I had full bars.
One thing to note: I don't use 2G or 3G or 4G or any other G. I just use WiFi for browsing and other than that, GSM to receive calls and send SMS. If you need 3G I think you need to change to some other settings. But you should give it a try.
Cheers!

Emergency calls only; When Android pie sleeps
I notice several times since I loaded Android Pie on my Oneplus One that the system, to save battery, is shutting down apps, even system apps. One of these is the phone service causing my phone to read Emergency calls only. After picking it up, about 30 sec, it registers 3 bars as normal. I am concerned that I am missing calls and text messages because after it turns on I get text messages. So, what is going on here? Any Ideas?

[Q] No Data Connectivity SM-G900F in Canada

Hey everyone,
I have a s5 that i bought in Greece while i was there. i have used it in Greece, Istanbul, and Spain with no problems, however when i returned to Canada i cant seem to get it to connect to the data network here. I am on Fido and i have tried all the various APN configurations that i could find on their support site. i have even left the phone with the store for a few hours to try and get it working and they had no luck. i know that its not teh network or the sim card because i have tried the sim card in a few other phones and it works fine.
Now this is the part that is somewhat confusing to me, I can call and sent text messages.... but anything that requires data, no dice.....
Anyone have any ideas?
Samsung support has been no help BTW. as soon as they see that its a European device they essentially say Oh, i dont have to do anything, call Samsung Europe... obviously that would be a really expensive call.

I had a similar problem with my S3 before and the way I fixed it was to find the correct APN settings and create a new APN setting page and fill it out, dont edit one that is already given to you but create another one and fill it with the correct apn settings which you can get from the fido stores. Have you had any problems with calling and receiving calls ? Let me know if this works.

i have done everything that i can think of as far as apn settings goes. i have reset to default apn settings, delete all the apns, and manually entered ones from customer service, deleted those and nothing... it seems like its an apn related problem, because i can see the network. in the about phone and status section i can see that there is an LTE network available, but my phone just doesnt want to connect to it..... ARGHHH

Does your provider use the 2600 frequency (band 7) where you live?, if not you can`t get 4G mate because the rest of the Canadian bands are not supported bij the G900F.

i get that, but im not getting ANY data. i should at the very least get 3G. the 900F has both of Fido's GSM bands 850, 1900

Did you try a friends simcard?, maybe yours is faulty somehow. Or maybe a data factory reset/reflash the stock rom may solve the issue.

Sorry, i kinda posted this like a noob would. i should have known better. i have tried the sim card in my old phone that i had before a samsung galaxy s2 skyrocket and it works fine.
I just posted this on the fido forums.
Hey everyone,
I have a samsung galaxy s5 that i bought in Greece and i am not able to get it to connect to the Data network of fido for some reason. i am completly stumped as to why. i paid quite a bit for it so it would really suck to get it home to canada and not be able to use it,..
So, before i get suggestions on things to do that i have already done, BEFORE i bought the SM-G900F (European factory unlocked and not region locked) i made sure that the bands would match up on the phone. its pretty much impossible to buy a phone that wont work in north america anymore. LTE is the only big question, but fido uses B1 and the phone has it.
I have used the phone with no issues in Greece where i purchased it, and also in Istanbul, italy, and Japan. I first thought that it was an APN setting issue, but i have been down every route as far as APN settings go. i have reset the apn settings to default on the sim card, nothing, i have manually entered the apn settings from the "how to configure an unlocked phone page" on this site and nothing, i have deleted all the apns manually then only entered the one APN for internet and mms, nothing.
after that didnt work i took thinks to the next level and did a factory data reset and still nothing.... then i took it one level further and re-installed the phones firmware right from baseline by pluging it into kies on the computer and download mode and all that good stuff..... nothing.
The strange part is that i know that the phone can see the network, because if you go under about phone and status, it will show the available network type, be it LTE or WCDMA, it simply says network status "disconnected"
I can send and recieve calls and SMS messages, but no data what so ever, mms, or internet.
PLEASE HELP!!!

Can't make calls when on LTE mode

I have n9005 rooted TouchWiz stock on 5.0,
when my phone is on LTE mode i'am unable to make/receive calls.
Kindly help me solve this problem.

Is the phone set to LTE only? If it is, does the carrier support VoLTE?

LTE/4G is a Data-Only network. To make calls over it your carrier needs to support Voice Over LTE, or VoLTE for short. Which is the mobile equivalent of VoIP.\
If your carrier does not support VoLTE, and your device is only allowed to access LTE, you can't make calls. Change to 'LTE/WCDMA (Auto)' (4G/3G) or 'LTE/WCDMA/GSM (Auto)' (4G/3G/2G) mode so the phone can automatically change to a network that supports voice codecs.

Not receiving incoming calls on AIRTEL 4G LTE
Iam facing peculiar problem with the phone. Need help with the problem.
I am using samsung note 3 LTE. When ever some one tries to call me, my mobile is Not reachable or out of coverage area even when my mobile is in my hand , perfectly working with the second sim. outgoing calls are working fine. Again, when I am in call, then if any one tries calling me, then I get call waiting. So incoming call waiting is working for me. But incoming calls are not able to connect. LTE data is working fine though incoming calls are not working. 
Tried the following but no luck. Problem still persists:
1. Reset phone and erase all data
2. Hard reset phone (volume down + poweroff and clear all data in drive)
3. Tried changing SIM to second slot
When I switch the sim back to 3G mode or 2g mode , incoming calls are working perfectly fine . I googled it and found that most people had same issue and was resolved on switching back to 3G or 2g . 
But I need to use 4g . Please tell me a solution.

I had that same issue until I took my note 3 to Rogers and they said that the note 3 doesn't support Lte

Your rom must support VoLTE.

I would unroot and go back to stock firmware, and see if problem still happens,? if it does ,its most likely the sim card.sd card reader slot, (flex cable),my Galaxy s4 had the similar symptoms , but LTE would work with a custom rom, but not if I used stock firmware, replacing sim card reader flex , just google your mak and model and search ebay. mine cost a few pounds for a decent quality part, so dont go rushing to buy the cheapest. No problems since replacing that part, even after resetting phone 3 times to see if it was a fluke. I know its a bit late for a reply, but this actually worked , I am 99% sure it would work for anyone else who has this problem with lte not connecting when 3G, and 2g do connect. If you have tried swapping sim cards, putting sim in another phone,, etc,etc. this part mentioned(sim card/sd card reader) is your culprit. Took me just over 5 hours of testing to find the solution. thanks and fair well android users

For many people having issues with LTE not connecting and diverting to voicemail on android, I am here to offer a solution to your woes. I have a Samsung Galaxy S4, GT-I9505, and recently in in 2018 in July, I had the same problem, phone calls connected on Gsm, Wdcma, BUT when I tried LTe mode, NOTHING, WENT STRAIGHT TO VOICEMAIL.Anyway I tried almost everything mentioned on certain websites and forums, with some luck, Changing LTE mode to GSM worked, and I could receive and hear phone calls. So I investigated further, I tried re flashing stock firmware, factory resetting phone.(nothing worked). I then rooted my phone and flashed a custom rom (do not try this) as it could damage your device if flashed wrongly. Yeah, so I flashed a custom rom, and low and behold problem disappeared, so I used my phone on LTE for 2 days, with no problems, I then decided to go bacjk to stock firmware, ...problem came back, not connecting to LTE mode..........being as patient as I can be, never gave up, and had a spare phone which was dead, just laying in the drawer, ..so ,I took phone apart and thought, it must be where simcard contact make contact with sim card reader contacts ( broken sim card /sd card reader part, and was I wrong, no, it actually was the sim card reader part which coonects with th motherboard, Voila, I am 99% sure if anyone else has this problem with any android that has LTE capabilities, and you know its not the sim card, then try this fix first, MAKING SURE YOU GET SOMEONE YOU KNOW TO HELP YOU , IF YOU ARE UNSURE OF WHERE TO BUY AD HOW TO FIT. hope this has helped,and I know it is a long thread, but hopefully it will be a solution that works for whoever reads and trie this, over and out. yours in sincerity, Tech82, from Surrey, England.

You should give it a try if you didnt.(does not void warranty)
Contact google, they will probably send you a replacement if you dont want to mess with it that much.

Yes,data works but calls don't

I'm going to suggest a longshot here. It seems that you've gotten some good suggestions so far, so I want to throw this idea out there.
Have you "provisioned" your phone lately & updated the PRL? Meaning, have you told the phone to connect to your cellular carrier, then the carrier then tells your phone what services you are paying for & are supposed to have & what cellular towers you can use? Doing just this usually fixes all sorts of problems.
Go to Settings (the little gear icon), then More (in the Wireless & Networks). Cellular Networks, Carrier Settings. Tap on Update device config. Let it talk to the network. Tap on OK. After that, Update the PRL. Let it do it's thing. Tap on OK.
No reboot is necessary. It should be making calls, receiving calls & data should all be working.
Also, I keep the Preferred network type to global, although my carrier is CDMA & I'm in the US.

HTC Bolt Mobile Data Issue

Hi, ive been an owner of an HTC bolt for a while now. Recently my island was hit by the famous Hurricane Irma (Puerto Rico, USA Territory). And ever since my mobile data dont want to connect.
Details about the phone:
HTC Bolt (Sprint but is GSM Unlocked and have been using it with H2O Company. Uses At&t Towers.)
Phone is bootloader unlocked and rooted but stock software i believe is the march latest update (1.32.651.6)
The phone was working excellent by that day. Now i had to switch to my spare phone HTC M9 and mobile data works fine here.
Rightnow i still dont have electricity at home. But i was wondering if any of you guys have had this same issue or maybe know why this could happen.
Ive tried resetting network settings, checked the APN multiple times. And no luck. Also i have access to the DM menu where i can see all the network settings when i input the MSL code. But everything seems fine.
Maybe running an RUU on it can fix the problem...
Thanks in advance for any help you can give me.

Thanks for the reply!
I thought of that but in that case my M9 shouldn't be working either. And its perfectly working. Don't know maybe is the LTE band it is trying to connect is bad or something. Because on the M9(Factory Unlocked version) the data is working but not as fast as always.

Oh yeah not really sure sorry.
Sent from my 2PYB2 using Tapatalk

this thing is driving me crazy. I'm on the line to Customer Service to see if they can find the issue.
But me guessing, does the radio image installed on the phone has anything to do with that? Does that file or part of the ROM could get scrambled and cause this kind of issue??
Update:
They have reset the account, but they say is the phone thats giving me the issue, since the SIM card shows successful connection on another phone. I will try to run the RUU on this and see...

Ok so apparently the issue is on the network. I just tried my sister SIM card from T-Mobile and the phone connects perfectly to internet. So apparently the issue is maybe a technical problem on the network band the carrier is transmitting. And that band isn't available or not accepted on the Bolt cuz is a Sprint variant.
Don't know 100% sure but apparently that's the issue. I checked on the M9 what bands are the phone connecting and according to LTE Discovery App the phone is connecting to band 17 or band 4.
BTW
Is there a way to edit network bands on a phone?
