[Q] No data and no calls

Randomly I have not been able to text, make calls or get a data connection with my phone. I was running CM 7.0.3 when this all of a sudden started. Restarting my phone would allow me to make calls and get a data connection for a few minutes and then I would not be able to do either. I flashed the newest CM7 nightly build and a new radio, Vision_Radio_12.57.60.25_26.10.04.12. The same problem continued so I flashed Virtuous 2.0.0 but that made no difference.
Anyone have any idea of what I can do to fix this?
Thanks.

I'd say try flashing a different ROM. But since you've fresh flashed the same ROM I'd say that pretty much counts.
Next I'd call the carrier and confirm that you SIM/account is in good standing, and that the towers are working properly in your area. I've had the freakout about "omg my phone is jacked up" and after flashing all kinds of ROMs, radios, etc. I just called T-mobile and they confirm that there was just a network problem in my area.

ur doing a full wipe right?

I actually did flash a different ROM and the issue continued. I'll be contacting Bell to see if maybe it's a service issue.

If you contact bell they'll know that you rooted your phone and they will have less sympathy to help you fix it.

How? Do like I did and google the right build number for your device because they will ask, and you don't want to get caught saying 'GRJ***'

This.

i tell my carrier straight up that im rooted...they dont say anything...but im not calling tech support either

If the OP is just calling to see if their have been any reported service outages or interruptions in his area, whether he is rooted or not shouldn't matter.
A couple times in the past few years, I've had instances where I lost both data and voice service for up to a couple hours at a time, over the course of several days. Then the problem just goes away. This seems to fairly typical, if they are upgrading or repairing your local tower.
If the OP has tried flashing various ROMs, and tried a new radio, I'd be inclined to say the ROM is not the problem. If the problem persists, you may ask your carrier to send a new SIM (or go to their store and ask for one).

hi,
you are not alone!
i have this problem with OE HTC 2.3.3 stock rom! (unrooted original device from Nov. 2010)
so i had very bad mobile connection and after ~1day (without reboot) i can't phone with it.. mobile network only "x" but data connection is fixed to gprs.
very strange!
so i send my phone back and orderd new one.
i think this is was hardware problem.
short:
- reboot bringt full funktion but the mobile connection is not so good as 4month ago (same point).. 4month ago it was "H" and now only gprs
after many hours >8h. calls didn't work, the phone said "no provider"... (x)..
- the strange thing is that data connection is degrade to gprs
this problem exist from the last 2 HTC OTA updates. but onyl the last 2.3.3 makes it really unusable
i hope this problem don't come back with the new desire z now rootet with cm 7.10 rc1 (what a feeling)

3 month old nexus no data or cell connection

My 3 month old galaxy nexus lost the ability to connect to the cell network, wifi and bluetooth are fine but when i scan for an apn it errors out, and i can not add an apn manually. i followed the thread to bring the phone back to factory defaults and re locked it like it was going back for warranty and that did not help, so it has the factory radio, bootloader, recovery and os 4.0.2 on it now.
do i have a $600 paper weight now? has anyone ever heard of this happening?

More than likely a SIM error if you've restored to stock and it still happens. Do you have another device or SIM to swap and test?

the sim is now in my blackberry torch that i have as a back up phone and working, even with out a sim in it there is no notice on the screen that says please insert sim card, but i am not sure if thats normal or not.
looking at the *#*#4636#*#* screen the radio keeps going from emergency calls only to radio off and back again.
edit: it does say no sim inserted, but its only on the lock screen so i missed it.

so looks like i am screwed with this phone, the store i bought it off the guy is freaking out saying why did you root it, (he keeps calling it jailbreaking) why didn't you just leave it alone, my response is why did you put those rims on your car, why did you change your desktop wallpaper, what can i say, i love AOKP rom.
but this is a hardware related problem, i put the stock radio and everything back to stock so what else could it be but hardware?
has no one ever heard of this problem with a gsm galaxy nexus?

The only time I saw this issue someone flashed the AOKP tablet rom.

i had been using the aokp rom for a few days before this started, and i just checked that is was the gsm nexus rom.
what fixed it on the one you heard about?

You are not the only one buddy. I am just south of Chicago and mine hasn't worked for over a week. I have full signal bars, but 7/8 of the time it reads that I'm not connected to the mobile network (as in my signal bars hardly ever turn blue). Even if it looks as if I have a connection EVERYTHING just times out. I haven't had the nerve to send it back to Singapore for a repair. The only reason I even own this phone is due to my drug abusing postal carrier inputting they delivered my GS2 and then simply didn't. Without signature verification its just a he said/ she said.

Phone lost connectivity.....is it hardware?

So my phone lost connectivity yesterday around 5pm. I though nothing of it at first, but then a few hours later it still was not able to connect to any mobile networks. I am unable to call, text or do anything with data for that matter. I tried the sim in my old trusty G1 and everything worked.
I called tech suppport and they refreshed my sim. I went through all of there troubleshooting non sense. The verdict? Warranty exchange...but wait....they are out of stock and have no estimated time of when they will be available.
Has anyone else heard of a phone suddenly losing all ability to get on a mobile network? I have been on the internet researching the issue for hours now and have tried everything I have come across, but no luck.
1. Left the battery and sim out of the phone overnight
2. Numerous airplane mode toggles
3. Connecting headphones
4. Phone Info menu and turning radio off/on + trying different radio settings
5. Reflashing radios
6. Flashing different roms
7. Odin back to stock 2.3.6 with wiping of everything
I am thinking I have been defeated by the galaxy s2.

I bet you were fiddling around with radios huh? I messed around flashing alternate radios to mine and my girl's phone and her phone was having this issue. Nothing would fix it, good thing I created a nandroid backup because all issues were fixed after I flashed back.

No...I wasnt doing anything to the phone. I had been running the same rom for about two weeks and was enjoying the luxury of amazing battery life.
While I was browsing the net on my phone, it lost signal...since then it hasn't returned.
I did do a warranty exchange so hopefully I will have a working device soon.

[Q] Text messages and calls not being received

I've been having a problem with receiving texts sometimes and I recently noticed that it happens with call apparently. The issue is that I'm texting people back and forth and then all of a sudden I wont receive messages for a long time (couple hours). At some point, someone's text message will push through all of the other ones all at the same time. Sometimes when I assume i'm having this issue, I will send a text to myself and it will push the other ones through as well. Recently though I was made aware that during this "outage", I also was not able to receive phone calls at all. The signal is strong at all times (3-4 bars). Also happens when I'm home all day and not changing locations when it will suddenly stop getting texts and calls. Does anyone know how to fix this issue? I restarted the phone and changed cell towers with the Airplane mode many times and the issue continues to happen at random times. It is really inconvenient. Suggestions?
Technical details: I use the stock 4.1.1 Rom that comes with AT&T S3. I do have LTE in my area.

And now it has happened 3 days in a row but at different times of day. This is a huge problem for me as I use my phone a lot. Any help would be appreciated

You still have your IMEI number via settings -> about phone -> status?

TRy making sure yiur not in airplane mode. i was stuck in airplane for a week ._____________.:cyclops:

That's weird. Re-seat your SIM card, if that doesn't do anything then take a trip to your nearest AT&T store/dealer and have them swap out your SIM card and see if it still occurs after that.

I had a similar problem a while back and it happened to be a network problem with my carrier. Gave them a call and all is fine now.

It happend to me too. I went to att store and get new sim. No problem for last 15-20 days. Looks like i got stronger signal too.

Just to give anyone interested in this an update:
I went to the AT&T store today and told them my issue so they told me to go to the nearest AT&T device support center (which was really far away). People over there told me they heard about this issue many times over the past couple of months. The guy working there had a S3 and said he has the same problem. They received an email from the higher-ups this morning specifically talking about this random outage thing I have and that they are currently working on it. They were told to not exchange phones or sim cards because of this since it wont help. The issue involves a combination of Network and Jelly Bean software problems and happens on all new LTE devices that have Jelly Bean from AT&T. They told me to check periodically if there is a solution.
I guess I just gotta wait. Unless someone recommends a ROM that is not based on the latest AT&T jelly bean?

Bumping it up, both me and my wife have had this happen. From what im read its a pretty widespread deal.
Anyone know of a work around at least until they fix it?

Keep us updated
Same problem here - switched from Verizon to AT&T last month and started noticing this problem a few weeks ago. Back then a Google search didn't find much on it, but this thread looks promising.
Just to add my two cents: I'm on a rooted S3 with task650's AOKP (4.2.1) build 12.23.2012 (link). Made sure to flash the modem for my phone (I747UCLI5 from here). Problem: phone randomly won't receive calls or texts. Sometimes calling someone will fix it.
I read somewhere that on AT&T, calls and texts are received over 3G and sometimes phones have difficulty switching from 4G. Anyone know if this is true?

Do a full wipe /system, /data, /cache, /dalvik cache. And your problems should be gone 9 times out of 10 that's usually everybodys problem

Seems to still be working fine.

I started a thread on this also and just yesterday received some info from AT&T tech.
http://forum.xda-developers.com/showthread.php?t=2123974

guys,
it is an ATT issue,
here is a temp solution for a fix:
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect
please see, post, comment here:

I have the same problem, every now and then it will stop having service and the only way to get it back is by rebooting, sometimes it works at first sometimes it needs a couple of reboots.
Any hint with this would be great
(this happened to me with aokp and cyanogenmod)

im having almost identical problems... like a month or 2 ago i reflashed to the new 4.3 slim rom. I have been fighting this thing every since. Ive tried so many different radios but yet i still have this issue, sometimes i can go days without problems but now it seems to loose data even sooner. ONLY way i get data (4G) back is if i reboot. Ive tried disabling then re-enabling data, same for airplane mode, nothing works. I think part of the problem is this damn rom.... i used to be on black bean 8 and for the mobile networks it had an option for "CDMA/LTE". This rom must be a ported rom cause the only selection for mobile networks that work is "CDMA/EvDo/GSM/WCDMA". I am on Sprint CDMA and LTE. i dont understand why this was done like this. I Would like to go back to blackbean 8 but i had problems with it and i like some of the settings for this rom better. Anybody have any ideas? Ive tried ALL the radios, none seem to be stable.
oh and i would post in there for the rom's forum but seeing as i havent posted enough here im not able to ask questions about it or anything :-/
