Hi guys,
I just switched to Bell (Canada) and have a Galaxy S3.
I have noticed in the last day or so that I keep losing the connection with the carrier. I will try to send a text message and it says unable to send right now and the notification screen will not display bell as the carrier. A few seconds later, it will work.
My connection when it is working is quite high signal (max bars)
Does anyone know what could be going on or how I might diagnose it further?
Thanks
I have installed an app called no signal alert and it seems that I keep entering "emergency calls only" mode every few minutes.

I've been rooted and running a few different ROM's for several months now.
I'm currently on XTRSense 5.0.1, having loaded it within the past week or so. All has been working swimmingly until this morning. I had used it to check weather and such before going to work (tho' I don't recall if I used home WiFi or 3G) and then hadn't looked at my phone till I got to work.
My phone signal was nil with an X over it. I tried toggling on/off for mobile network but the widget and the Options checkbox are both greyed out. I tried rebooting the phone and it still didn't come back. It prompted me to set my clock b/c it wasn't getting network time anymore (1st time I've seen that).
Feeling desperate, I even tried changing the NAM CDMA settings to EVRC-B just to see if I could "jiggle the handle" for the mobile network and get it going. All to no avail.
Text messages do not reach the phone, and calls ring through to voice mail (though not immediately, as though it were ringing the phone).
I'm at a loss and doubtful I could call Verizon to get much help.
Any help anyone can provide would be deeply appreciated!
Thanks!

Disregard... Verizon must be have a weak day and my coverage is a bit dodgier than usual. I usually have better coverage at work, but I had to go hunting for better signal. I guess that's what I get for troubleshooting while sitting at my desk...
I'm facing this problem since i bought this phone.
When i set my phone to WCDMA/GSM OR WDMA ONLY mode my phone drop randomly calls and in 80% of case unable to make call ("conditional call forwarding active" repetedly appearing till call is ended).
When i switch to GSM only mode the phone run smoothly without any problem..
P.s : i thought it was related to the 3G/H issue but i don'T know exactly caus' even when i'm connected on Wifi it's the same problem.
Your Help will be very appreciable.
Regards,
please any help .. anyones facing this issue .....please help!!!!
F-f-f-f-factory Reset!
You get it on a plan or something? Or outright?
I'm afraid does'nt work for me!!!
I would guess its to do with you having a weak 3g signal and you will be connected to 3g when you make a call, then move into an area that's gsm only and the call will therefore have to drop as the signal changes.
I have a widget that goes to the mobile networks settings page and tend to keep my phone on gsm only while I'm not using the internet or on wifi etc then switch up as need be.

can you give me the name of the widget please?
Hello,
I found one thread about the same issue but didn't want to revive it because it's in an HTC Incredible S dedicated forum. Anyway, I am having the exact same problem as described there and I've been looking for a solution for months now...
Incoming calls fail when the phone is switched to 3G.
Until I came upon that thread, I thought this problem only occurs on Hypersimmed Japanese phones -- Japanese phones have a SIM lock that can only be overcome using a hypersim and even then they don't usually work fine in 3G.
Some hypersims, however, seem to be able to "do something" about this issue - while I have zero issues with incoming calls under 3G on my 904SH (2006 model), the problem described here occurs on my Android-powered Sharp Softbank 005SH.
So, I can connect to the 3G network (when in 3G only mode - if set to AUTO the switch causes the phone to lose signal and the SIM must be inserted in a "normal" phone to regain signal, we call this "CPR").
3G data works and 3G incoming calls work -- as long as there is an active data connection.
One way to do this was have Skype running all the time - huge battery drain and still incoming calls would occasionally fail as Skype doesn't seem to update its data at fixed small intervals...
I have estimated that the data connection closes in about 30 seconds, which means that after this period, incoming calls will fail.
I tried a small app that a friend had written - a screen widget that connects to a server at a fixed interval, e.g. 20 or 30 seconds, and displays different small photos.
This app does the trick as long as the phone's screen is on. If I switch it off, the app continues working, and even lights up the screen every 20 seconds (at maybe 1/3 of normal brightness) but incoming calls fail.
Now, in the above mentioned thread, the user only writes that his problem got fixed by itself.
I too have excellent 3G coverage and it's not a local problem (near my home's signal tower).
So, any ideas will be welcome!
Hi guys,
I have installed CM7.2 nightly version on my ace, but not I can't stay connected to the mobile network (bell canada).
If I turn the airplane mode on and then off the phone is able to send messages and seems connected, but few time later, it seems disconnect (does not show a message that lost connectivity, just can't receive or make calls or messages).
Does anybody have a clue?
Thanks

Hotboot...... If then also u experience that problem, change ROM.
First let me start with the phone:
AT&T Galaxy S II running 4.1.1 SuperNexus Rom Build 4-20121007. Kernel is 3.01.15-CM-g3802d32 faryaa kernel. Baseband 1777UCLE5
Everything was working fine. I've been running SuperNexus for about a month. The only initial problem I had was that the baseband was not working upon startup and I had to put a new baseband in for it to work, got that fixed and been flying smooth for a month with no issues. Today...suddenly it stopped being so smooth.
Let me clarify:
- I can make outbound calls and hear just fine (couldn't do that when baseband was wrong)
- I can recieve and send text messages
- I show a full reception bar up top with 3g, the signal bar is grey. That may mean something or it may just be the color theme for this rom. I didn't really pay attention before the issue.
- Network info: AT&T network, Signal Strength -83 dBm 15asu, Mobile Netowrk type UMTS:3 HPSA+ :15, Service state is 'in service', Mobile Network Status 'connected'
I was literally in the middle of surfing the internet and pulled up a browser for a webpage, suddenly it hung in terms of loading the website. It did nothing for about ten minutes. I then found that all apps that use data do not work. They attempt to load but give errors. I rebooted the phone several times, shut it down fully several times, removed the battery and sim card, replaced and restarted. None of that worked. I made a call out to a friend and he could hear me and I him very clearly, call dialed out and connected without issues. Text messages come and go just fine.
The only thing I can think of is that they turned on the 4g signal in my area, or near it today and maybe there's an issue there.
Please help.
Thanks in advance.

My friend was having literally the exact same issue today on his S3 and I was having a little problem on my phone too. At this point I think it's AT&T. My S2 was not go to HSPA+ it would just stay on 3G when I turned data on.
It is AT&T. They are changing the APN they use for data. I posted a fix for this in the other thread relating to this issue.
