"No Service" repeatedly on my stock S3. WTH?! - Galaxy S III Q&A, Help & Troubleshooting

I've had my S3 for about a month and 4 times now I've discovered my phone isn't connected to my mobile service provider (Telus in Canada). Notifications will say "No Service" and it means no phone calls, messages or data at random times and it stays that way until I notice it and reboot. There is no logical reason why this should ever happen, I never leave the service area and all the settings for Mobile Network remain set to Telus. When this happens there's no way to fix the connection through settings, have to restart the phone.
I have a second issue that is also very frustrating - whenever I call my voice mail I have to input my passcode. So I place the phone down in my lap, enable the keypad and attempt to enter it. As soon as I touch the keypad the screen often just blanks out and no touch is registered. It's as if a proximity sensor thinks the phone is still by my ear and disables the screen. So this makes it extremely difficult to enter anything via keypad.
Any ideas on what could be causing this no service issue - a faulty phone or could it be related to a bad SIM card?

Try switching your modem.

wrong forum? or do u really own I9300?

Why does it always say "Conditional call forwarding active" when I make any call?

Why does it always say "Conditional call forwarding active" when I make any call?
Hi there, basically I bought a new and sealed T-Mobile branded Samsung Galaxy SII phone from eBay and am using my 3 mobile sim in it.... I assume it wasn't originally locked when I bought it, as I went through the root and unlock method (ChainFire app), and the code was 00000000, and never at any point asked me to enter that code into the system, so hey, my 3 sim seems to work in it.... apart from the fact that for every call I make the message "Conditional call forwarding active" always crops up with a beep to go with it, then after a couple of seconds the call is made. It isn't a major problem as such I don't think, but hell it definitely isn't normal and is quite annoying after spending £400 on this otherwise amazing phone.
I have tried to fiddle with the settings but for some reason I cannot disable any of the call forwarding settings, some sort of error message crops up. I have phoned up the 3 network who I am with three times today and they asked me to enter a few # codes to sort the problem out, but I had no luck, and then they had me factory reset the phone using the option in the settings. I did that, and I still have this problem. I also get the message "Connection problem or invalid MMI" when entering most # codes, this seems to have happened after rooting, though I am not 100% sure if that is the case.
My phone is the Samsung Galaxy S II I900, just to confirm that.
I look forward to hearing from you guys
I am on Three and I get the same message although my S2 was purchased from O2 then rooted. I have not seen any other reports about this but the message has not bothered me.
I have the same message. Ave tried several hings without success, however since it really does nothing, I am starting to get use to it. But if someone knows how to solve it please let us know
voice mail
Hi guys i have this to but it only started when i activated my voicemail so i think its down to the voicemail
e.g if your on the phone and someone else calls they are placed forward to your voice mail ???
hope this helps
Hey there guys, thanks for the replies so far, glad to hear others are experiencing this annoying problem. I seem to have had this since rooting it, originally T-Mobile though I am 99% it was never "locked" to the network for some reason as I mentioned as I have never had to enter the 00000000 code, which the free ChainFire sim app gave me (seems like it means it is unlocked already???). The guys on the 3 helpline were giving me loads of codes which weren't of any help, and telling me about what options I could fiddle around with, but I had tried all of these to no avail.
Are people also getting the MMI message I mentioned in my original post, whenever they enter # codes in the dialer? It seems to me that both of these problems started at the same time (this error message and the forwarding issue - I am sure they are linked). It means, for example, I probably won't be able to set up a speed dial because of it, nor will I be able to use the "secret codes" as mentioned in the dedicated thread of the same name on this site.
Why is it a problem for some and not for the majority of people, we must have something in common which we have done with our phones which has caused this?
I really hope someone can sort this annoying problem out.
It's normal. "Call Forwarding Active" is displayed when all calls are forwarded. "Conditional Call Forwarding Active" shows when forward when busy, forward when unanswered, or forward when unreachable is selected. To make the message go away you'd have to disable the three forwarding options in their settings. The pre-populated number is always your carrier voicemail (read from the SIM) or Google Voice.

Cheers for the reply Barry, yeah I expect it is normal but the thing is I cannot change these settings, my phone won't let me as an error comes up. I know it's not a major problem, just a bit annoying I can't get it to go away. I can't disable those three things, I tried a few times already.
Plus, I constantly get the MMI error message, which I mentioned before, seems a bit of a coincidence how these problems started the same time. I can't enter the majority of "#" codes into the dialer, it always says "USSD Running" or something along those lines and then produces the message like 2 seconds later.
Any ideas? Thanks so far for the advice
I have this problem but unlike all others I cannot make any calls on account of it. When I try to disable call forwarding I get an error msg saying it's not supported by the operator.
There HAS to be a way to fix this. I cannot make any calls or use 3G.
Try this
menu-call-additional setting-select network default...
It work with my sgs2.
On the Galaxy S2 if you go to: settings-call-call settings-call forwarding-voice call forwarding -- You will most likely see that for unanswered or unreachable calls it's not disabled because it forwards it to your voicemail, that's why it says conditional call forwarding is active. If you disable all options you won't get the message but then unanswered calls won't go to voicemail.Hope that helps.

you realise thats almost a year old? Check the dates on threads before you post
ADMIN EDIT: True, but it is a current issue for some people so it's still valid to answer the question.
Doesn't work
My phone drops every call, even with SIM cards from different countries and in all conditions. Thinking this call forwarding might have something to do with it, I tried to deactivate it, first through the settings -- no luck -- than by reformatting the phone. Nothing, cannot get rid of it because it says it is set by the 2 different phone companies I use.
I don't mind the message but when I call someone, I can hear that the call is being sent somewhere, there is a 1st ring, then it rings the other phone. Does this have to do with call forwarding? Can it be interrupting the phone signal and causing the call to drop ?
I have also removed both the Turkcell and Telefonica SIM cards, put them into another unlocked phone and tried to cancel but as soon as I put them back, the message returns and my calls drop.
Im also getting this error when I updated to 4.1.2 and used galaxy s2 sim unlock
Has nothing to do with call forwarding !!!
The Message worked on all AT&T cell phones, since i can remember,. i been using go phones since 06..... and they all had this message when right after the number was just dialed, right after pushing the green phone icon button to dial it , right after entering the number to be dialed on the keypad.
I have found this message on LG Cell Phone 500 CU series... and all my other phones as well...
IT is NOT a CALL FORWARDING ISSUE>.. because i had worked on that for awhile myself...
IT is a Carrier Issue I believe.
and it doesnt happen ever single time , just on certain days . not sure, why... but perhaps, call your carrier and ask them what type of phone they have your phone listed as.
Then tell them the model and make u have. that might change things... Cell phone carriers know how to mess with your phone and break it too...
so if ur having issues with messaging, call forwarding, it just may be the settings the carrier has you listed or down for.
blah.
anyways. yes it is annoying, i just got a new phone, samsung galaxy express. it is starting to happen too on this one. but had it for a few days and it never showed up till about 2 days later.
I thing it is perfectly normal for your device to display this message, I'm central america and mine also says the same thing anytime i make a call "Conditional Call Forwarding Active. However since I have a prepaid or pay as you go plan with my carrier and whenever I have no more credits to make calls i get the message "Calling Barring Enabled". I guess it has something to do with your carriers settings, it doesn't bother me at all though since I'm already used to it so hope that helps.
Enabling call forwarding for real and then disabling it seems to work
I got the same error also on every version of the stock rom (it used to appear occasionally, though) on my Samsung Galaxy S2 (i9100, without g), in that case going into forwarding settings was enough, because the mobile used to read the current configuration from the network and recognized that there was no forwarding active!
I moved to Cyanogen Mod 10.1.3 / Stable and going into forwarding settings was useless... He was updating with the data from the newtwork, all the forwarding options were disabled but the notification message was still there...
I decided to enable it for real by putting a friend number from the same carrier and then disabling it immediately after, and it solved my problem! Hope it helps!
PS: I'm not sure that enabling the call forwarding is free of charge, just double check with your carrier first!

I had the problem. Just solved it. select any one sim. Select settings-call settings-call forwarding-make sure all the options listed therein are disabled. Do this selecting all your sims one by one. The problem will have solved.

[Q] Incoming calls fail on 3G on hypersimmed Sharp 005SH

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!

qpst and cellular calling

After using QPST for my Dad's Inc4g it has 2 odd cellular problems.
#1
It can make outgoing calls for a few minutes.
But then it says that the “phone number is not active or invalid” (like it’s not activated).
Then the only call it can make is to 611 (data and wifi off), but it gives me his correct balance and minutes used (so it's still connected to his account).
Rebooting does not allow it to make outgoing calls either.
It's as if it's partially dropped off the verizon network somehow because turning the radio on and off again also doesn't work (airplane mode on/off).
And when another phone calls him it goes straight to his voicemail.
BUT….if another verizon phone calls he CAN receive that incoming call no problem.
*Then once he answers that incoming call, he can magically make an outgoing call again!
So can anyone tell me what I might need to change, to stop it from loosing the ability to make outgoing calls?
It’s brand new (NOT rooted or anything else).
The Preferred network is set to CDMA only.
Only changes have been through QPST, and switched to NV-Only mode so he doesn't have to use the sim card.
Also after QPST the roaming triangle popped up, but I have the 58012 PRL (isn’t this the latest for this phone)?
#2
If he starts to dial a number, but then immediately hangs up (accidental dial), his next call gets the "system busy" network error.
Then attempting to make a call after that gives the same error as above (requiring a verizon phone to call to get him back on the network).
Could someone try do this and see if they can repeat this error?
So to anyone who has used QPST with this phone, or flashed it to another carrier, do you have any change suggestions for either of these problems? Maybe changing something in EPST?
Thanks for your help.

Network Issue - When called to my number it says switched off!

Guys, I have a strange issue, 3 hours of IDLE time on my phone and when you call my number from other phones, it says it is Switched off!!! The network signal is full, strangely if i callback someone it rings, and then if you call me back, my phone rings normally!
I do not know what the issue might be here, I have tried resetting the phone, reinserting the SIM card. Changing the Networking setting to only GSM, but nothing helps!
This is not good, and it is causing me lot of headache, as I am missing important Client calls anyone with a remedy?
Guys .... anyone who can help me out here ?

Sounds like a network issue. Make sure you don't set the network mode to automatic/auto connect. Other than that, I can't think of much.
Edit.
Check your edge preferences and turn off any of the flip to mute functions. Also double check call rejection in Phone to see if it's rejecting calls for some reason.

phone calls out to contacts without me knowing?

i'm looking at my call history and it shows that i've called people, when i didn't try to call.
anyone have this issue? is the phone showing or calling people without you doing anything?
Do you have "Tap to wake up" option enabled? I've had similar experience with one trousers' pocket! For some reason the fabric in that pocket would activate the phone as if i've tapped the screen. Even though i have fingerprint with pattern lock, i've found my phone many times in Emergency keypad with random numbers pressed.
