Can't dial out or receive calls intermittently with 3GS and 3.1

Join the club!!! I have 3G activated with full bars and I it will take about 15 minutes for it to load my email. I cannot check voicemail, load webpages, or send text messages. They need to fix this soon!!! I never had a problem until the 3.1 update.

Also the other day I got about 5 calls, my phone never rang for any of them and I had 3 voicemails from those calls which never showed up. It never even showed up as recent calls. I had to restart my phone for any of these to show that I missed the calls.

I've been having the same problems with mine. I have the 3G and even before the 3.1 update I was having this problem. I've also been having a lot of problems with calls being dropped, but I think that is more AT&T. I have also had my phone totally crash and become unresponsive twice now. The first time I connected it to my computer and it read the phone and I was able to restore it. The last time, after the 3.1 update, the computer didn't even read it and it wouldn't charge. I took it to the Apple store and they were too busy so I had to come back the next day. Of course my phone began to work before my appointment so Apple said they couldn't do anything. They did tell me however that when it happens again to bring my phone in so they could verify it was not working and they would exchange it for a new one. Now I just have to make sure I sched. an appt. for the next time my phone crashes.

Well I fell better knowing this isn't just ME! I was just freaking out. This started yesterday (I updated to 3.1 maybe two days ago) or at least yesterday that I noticed. I'll head over to the AT&T store today & see if they can switch out my SIM & cross my fingers that it will work. If not, I guess it's a restore- which I so do not want to do... ugh.

I got a new SIM card from AT&T three days ago and so far I have not had the problem anymore. Before that, getting new phone, restoring did not help. So, I am curious to find out if a new SIM card also takes care of the problem for other people.

I get hung up on Text messages. and occasionally calls.
the update (3.1) took hours to update. i almost thought i had a paperweight.

it hasn't happened that much. but my house seems to be a Service deadzone. just inside. the lawn seems to get perfect 3G

OK. I posted the last time this happened and I was pretty **** off. I flipped the airplane mode on for a few seconds and then back off. I then went in and reset my network settings. That was on the evening of the 15th. Here it is 2 1/2 days later and everything seems to be working fine as far as call and SMS go.

well this solved my problem so far.

I just took off 3G and i havent had any issues so far for about 2 days now.

It happened to me again last night. Unable to make make or receive calls or texts. I did a reboot of the phone to fix it again. I tried the airplane mode trick the other night and it did not seem to have any effect. Next time this happens, I'll just try resetting the network settings to see if that makes a difference.

I was having this same problem for several days after I updated very early on 9/10. Then on another thread I read that if I turned off my 3G network and only used the E(dge) network my calls and texts would work like they were supposed to. So, last Sunday or Monday I switched over to the E network and stayed there for the entire week.

Last night I switched back over to 3G and so far so good! Previously on 3G my phone would get "stuck" as I called it or go into the "zombie" state as others have called it, at least 3-4 times a day. A power off/on and/or hard boot would fix it for a while until it happened again. So far its been almost 18 hours and its still working. Every now and then I'll send a "test" text to a friend just to check and make sure its still working.

I'm not saying that switching over to the E network for 5-7 days is a fix, I'm well aware that it may not have been a factor in my phone working properly again at all. But since so many people are having the same problem and all the Apple & their "volunteers" won't admit that there is even a problem at all I thought I would post my experience just in case it might help someone else. Especially since we're not getting help from the source of the problem.

In my case, it seems to be a fairly well-defined problem: after discontinuing use of a bluetooth audio device, the phone's bluetooth doesn't let go. So then the phone speaker doesn't work. Cycling bluetooth off and on again restores proper function. Meanwhile I can tell there's a problem because the phone doesn't make the usual sounds.

I've been having this "randomly loosing connections with the networks without any visible indication" problem, I don't know if I had it before 3.1 but I realized after 3.1, Anyways, after searching a bit in forums, it seems the cause of this problem is the Push notifications, turn off all the push notifications for all apps, including mail and calender, then use your phone like this for a while, and see if anything changes, mine is working fine so far, the problem seems to be solved. Give it a try and tell us if it works or not

Went to Apple Store 2 days ago. They reinstalled 3.1 and told me to connect to iTunes as a "new phone", requiring a complete reset-up of all my preferences. So far, the phone is working for 2 days. I hope this is the solution.

I've been having the same problem for the last week or so. An average of once a day, my phone will display full bars but no calls/texts/3G data works. Wifi still works. I'm using a 3GS, and the only thing that restores functionality is a full power off/on.
