So I've had this issue for a while and it was extremely frustrating. Although I don't use cellular calling often but there were some times where I needed it, and after all, it's not a "phone" if it can't make calls. So let's start with the simple fix first, go to Settings> Cellular Networks> Preferred Network Type, and set it to 3G. If this doesn't work for you, try flashing a new radio. Mr.shme made a great thread where he included several versions in it, you can find it here: http://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-lollipop-t3300907
I hope I helped you if you're still facing any issues just tell me and I'll gladly try my best to help you.

Hey
I know there are threads related to this issue where an Hero refuses to connect to a network (the bars has a x over the top) however i've discovered something strange with my hero.
With the correct data/apn settings the phone is connecting to the network and will allow me to browse the internet, post tweets etc etc, it actually allows me to do anything thats not phone related. I cannot make calls or sent text messages.
This phone was unlocked and working ok until one day it just stopped working with my network.
The hero is unlocked - I have tested it with Tmobile and Three and they both work. Any kind of o2 sim refuses to work....
Am i being a complete n00b and missing something here....?
Any help appreciated - I;ve spent weeks on this issue and almost ready to give up

Anyone having a similar issue to the above, I've found something that appears to help fix this.
Get AnyCut from the market place, create a shortcut to Phone info.
Launch phone info, turn off radio.
Now im not exactly sure why this works but change 'set preferred network type' to WCDMA Only and then renable the radio after a few moments, the singal returns.
Weird and very annoying.
Damonsk,
Can you point me to a solution for the other problem where the hero refuses to connect to a network (the bars has a x over the top). I have searched every term I can think of with no luck yet. Thanks in advance for any assistance you can provide.
Hi all
I am having a problem lately in making/receiving calls. The only easy the problem is solved is by using the band GSM 900. If the band selection option is set to determine automatically then I face the problems although the network is full.
The band selection is changed using *#2263#.
Note that the phone was working fine with the default band settings until one day I lost my emi and then had the samsung service centre restore it.
Have been having toys problem since then.
Any solutions?

i have a very similar problem. my issue also started a few days ago. only, i haven't tried using that frequency band that you mentioned. the thread that i started here didn't get too many replies, but i googled stuff and i found out that the issue is with the data connection.
try disabling the data network mode whenever you're not doing it. that has solved the problem with me so far. but, if you do find a way where you can use the data network mode and make calls easily, let me know also please.
thanks.
EDIT : i think you mean IMEI. and i didn't lose it. how did you manage to lose yours? i thought flashing was safe. which version of what ROM are you using now? and which were you using before?
Yes IMEI was what i meant. Did something stupid to loose my IMEI. And yes flashing is quite safe and does not touch your IMEI.
Was using DDJP2 when this issue started. And have flashed many roms but the issue still remains.
And i dont use any data network so my data network mode is also in disconnected mode.
And to further describe my problem.. when i make a call to a nokia phone the call almost gets connected and the nokia phone also gets lighted on with the small lock sign coming up... but the call does not connect completely ....
The only solution i could find (after weeks of digging) is to default the band selection to GSM 900... but i am sure that there should be a better solution for this.
I was using using eclair when my issue started. then i upgraded to froyo DDJP2 and my issue went away :/
but it has started again off late, no matter which ROM i use. I tried doing what you suggested, that is to set the default band to GSM 900. but that only for incoming calls. as in, i can receive all calls properly but my outgoing is still faulty. it just dials and then the "call ended" screen comes with the dial and message buttons. and when the data network mode is activated (it is by default. are you sure yours is switched off?) for me, my calls barely ever go through. there is a significant improvement when it is deactivated.
I'm looking for a better way out too.. I'll let you know if someone helps me out either. Good to know i'm not the only one here who has the issue.
Yes am sure.. the network data mode is always deactivated for me here.
Yes hopefully we can get some better solution here.
I lost my IMEI..samsung repaired my imei...nut im not getting calls or sms....even out going calls also.........plss help mee
i am havin a similar problem , sometimes (a lot ot times) people call me and my phone seems to be closed to them , but it works normally :S , that problem started when i flashed the phone and it remained after i flashed a lot of roms (even after factory reset) , and i cant understand if its a software issue or a device problem..
i would appreciate any help
and now i'm facing the issue even when the 900 band is selected (but data network mode is activated, which i don't want to disable because of whatsapp and ebuddy and gmail and tTorrent)
wondering if any recognized developer could help us out with this problem..
Hi All,
I have been facing a strange issue with my Yureka.
Many of my friends and clients are complaining me that your phone is not reachable. To test this, I dialed my number from another phone and found they are right. Sometime it says, phone not reachable and sometime it doesn't say anything... just ... ping... ping.. ping and gone. Not even any message. I can see full network signals.
This has become now very annoying.
In last 1 hour, I have tried my phone 10 times and got connected only 2 times.. rest of the times either it doesn't say anything or says, not reachable.
Any ideas what could be wrong?
p.s. A little more info... while phone is not reachable, I can see full network and my 3G is also working fine.
which Rom installed on ur phone? & did u try calling to both sims?
Thanks for your reply ujilraj.
I am on stock CM12 ROM
I have no issues in outgoing calls. Issue is when someone is calling me.
They get phone unreachable message or nothing at all.
Today I tested myself and saw the same.
Earlier, I thought it might be some network related issues but it seems something else... may be hardware issue but not sure, therefore, asking for community help
Do u use dual sim? & did u set the network to automatically choose network? (settings > mobile networks> network operators> choose automatically). Also, Is ur preferred network type set on LTE? if yes, then change it to 3G or 2G...
Hi all,
first let me thank you in advance for any tips and hints that might help solve this mystery.
I was running Cyanogen on version 13 without any issues but since the project halted I wanted to update/upgrade to LineageOS. I updated a month ago (clean install) and after this upgrade the problems started.
The symptoms are very erratic but the problem is that I lose cellular data connnectivity several times a day. I still have voice calls, but no 3G/4G connectivity... sometimes I have a small "x" on the network symbol but other's there is no visual indication but no connectivity either (no web browsing, no whatsapp, etc.). All this goes away if I turn on/off airplane mode but after some time I lose connectivity again.
I thought the issue might be with LineageOS and I clean installed Ressurection Remix yesterday, but the problems remain... same issue.
Broadband is G900FXXS1CQAV
Any hints?
I believe that after all this time I have figured it out!
The APN settings were not correct for my provider. The "Authentication type" was incorrect!
Hope this helps someone in the future.

Let me preface this by first saying, I am using the A20U (So I know rooting to fix this isn't an option. feelsbadman.jpg) But I have an unlocked VZW A20, and am trying to use an MVNO to get data and all that good jazz.
The weird issues is that my LTE (and all of my network for that matter) seems to disconnect it's self about 2-5min after connecting it it. I know it's not a SIM issue (as I've tried this sim in my wife' phone, EXACT same model.) with no issues. I am going to go over all the steps I've taken, as well as the "temp-fix" i've found for it and maybe one of you righteous nerds can help a fellow nerd out...I'm going INSANE.
Temporary Fix : Using "Hidden Menu" app, I can go into the screen and change the preferred network type, (LTE/UMTS auto PRL get's my data, texts, and calls working before dropping off randomly.) I have good signal, and no other issues.
I have XAA/XAA/VZW and Verizon has confirmed that it is indeed SIM unlocked. So I am rather at a loss on what to do. Flashing any files I can find through Odin seems to yield no results for me.
Thanks in advanced! <3
