IPhone 4 needing reset to access data
 

My IPhone 4 keeps losing data service.... I still have normal phone service but if I want to access data Im forced to turn off the phone. When I restart, I immediatetly get back data service. Any ideas...?

I havent updated my OS.... can this be part of the problem...?

Thanks,

OS updates do wonders for iPhone 4's

what version is it running, and on what carrier?

Assuming its a SIM-based iPhone, take out the SIM, give the contact points a clean and re-insert.

What is displayed on the screen (3G, E or O)?

Does it access data through wifi ok?

Does activating "airplane" mode and then turning that back off give you data access again?

Att, Verizon or Sprint?

1) Yes, it is a SIM phone. I will try this.

2) When the data works, it will show 3G, and sometimes E or O... when the data function dies, it will show none of these, only the normal phone carrier logo.

3) Yes, WiFi data function works well.

Thanks.

Ive tried this... but no, it will not revive the data.

I dont live in the US, so I use a local Argentine Carrier... Personal.

I guess I will have to do the OS update then..... :p

I had this once, and reset network settings did the trick.

Tried this.... doesnt help.

You can reset many functions on an Apple by pressing the Home and Power button until the turn off slider appears. Instead of turning the phone off, just cancel. It is almost like respringing on a jailbroken iPhone.

Are you on IOS 5 and jail broken? I just updated to IOS 5 now that there is an untethered jail break and have the same issue when I run a couple of jail broken apps. I have to totally restart the phone to get data service back.
The little research i have done, it is a know issue.

My iPhone has been all sulky and raggy for the last week too

Connects to wifi then doesnt do anything
Sees wifi but cannot connect to it
just landed back in Colombia and put my contract chip back in it and nada searching... had to reset the network settings for the third time in a week

Is it the phone or has anyone any ideas?

No. This is a factory unlocked IPhone 4.

I have not yet been able to update to IOS 5, Im still working on this.... just started with this and also having issues.... :rolleyes:

Ah... this is a good tip, I will give it a try. Thanks !!

I recently had a problem with an Iphone 4S on my plan not accessing the data network.

I could call and receive calls, texting worked fine, wifi was fine, but when not on wifi, I got an error that could not connect to network, even though the 3G symbol was lit up on the device. It looked like it should work, but didn't.

I have Verizon service. So I went through several steps. First, I ended all programs (double tap home screen) and then held home and power button down to reboot. That didn't work. I tried flipping on and off the wifi switch, still no dice. I flipped any switch I could. Then I called one of the numbers that activates a smartphone, that didn't help.

Furstrated, I called up Verizon customer service and told them what I did so I wouldn't have to jump through hoops. First level CSR escilated me to a Tech. He checked on some things and still no go on the network. They then esclilated me to the network team. Two hours later I get a call back from them to check to see if it worked, and FINALLY i was able to surf on the phone on the 3G network.

I talked to the network tech to try to find out what went on. All he told me is that the problem was on their side, and nothing would had fixed it on the customers end. Something about the profile for the phone to hook up to the network had to be changed. Would have been nice to know the exact issue.

I at first though it may have been the phone, but it was something with Verizon. Could be a similiar case here if you can't get it going.

Ive managed to update to IOS 5 and this problem has not surfaced since..... ^
