I updated my iPhone to 5.1.1 and cannot get a 3G signal and also cannot activate cellular data. The same problem happened to a friend of mine too.

my iPhone will not connect to cellular data, it was working fine then just stopped.
Info:

I have a Google Nexus 5 and it's hooked up through Straight Talk's AT&T towers. Yesterday my phone randomly stopped being able to use its 4G, so even though it shows that I have full bars I can't connect to the internet using my data AND it seems as though I'm not receiving text messages. When I try to make normal calls, an automated voice tells me that something has been "deactivated".
I haven't reached my data use limit yet (not even by half!), my bill for this month is already long since paid, and I haven't downloaded/done anything that seems like it could have led to this. I've tried a couple of other fix-it methods but non seem to work.
AT&T and iPhone data use charges - WiFi and cellular link options Many people have complained about unusual data usage charges on their AT&T iPhone bills -- often 10s of megabytes in one transaction, posted in the middle of the night. Here are a couple of updates based on the AT&T support portal: WiFi vs cellular link: Connecting to a local WiFi hotspot and turning off your cellular data connection will block cellular data transmission and related charges. (Except for SMS messages, which are very small.) There are some gotchas, however: (a) If your iPhone goes 'to sleep' (the screen goes black), it will revert to the cellular data link, unless it is plugged into a charger. (b) Even if your iPhone is plugged into a charger, it will revert to a cellular data connection if the WiFi link drops, e.g. due to a momentary glitch with your internet provider or electric power supply, so.... (c) The only way to completely ensure that your iPhone will not revert to a cellular data connection is to turn it completely off. You (obviously) will not be able to receive calls, however.
Large data transactions in the middle of the night: Unusually large 'chunks' of data that are apparently sent around midnight are a related issue. You may think that you could avoid these mystery charges by making sure you have a WiFi connection running at night. A number of 'czars' on AT&T's site stated, however, that this is are simply an artifact of AT&T's billing system, which "aggregates" transactions that occur throughout the day into one summary charge, which is posted in the middle of the night. If this is accurate, the data connection(s) you use throughout the day will determine how large this 'summary' transaction will be.
Note: Our bill does not appear to square with AT&T's explanation. For example:
39 04/06/2012 09:36PM phone Data Transfer 7 KB 0.0040 04/06/2012 10:35PM phone Data Transfer 7 KB 0.0041 04/06/2012 10:41PM phone Data Transfer 369,759 KB 30.00
If all of the data from 6 April was 'rolled up' into the massive 369.8 megabyte transaction at 10:41pm, why are there two small transactions at 9:36pm and 10:35? We installed Onavo to try to get to the bottom of this;; I will post the results at the end of the current billing cycle.

I bought an iPhone 3GS off a guy on craigslist and it works great, no complaints. But every few minutes or so I get the alert saying that I "Cannot activate cellular data network - You are not subscribed to a cellular data service", and it's really annoying because it lights up my iPhone all the time and kills my battery. It's also really annoying - it comes up whenever I'm typing a message or playing a game; literally when I do ANYTHING on my phone. I do not have a data plan, but I have used 'unlockit.co.nz' to install a Fake APN to my iPhone to block data. Rogers has also given me a data block. This has been going on ever since I bought the phone, I thought installing a Fake APN would stop it but I guess not. I can't really restore since I have a lot of stuff on this iPhone already.. but if that's the only option then I will be forced to. I used to have an unlocked Fido 3G (about 2 months ago) without data and it never gave me this alert, do you think it has something to do with my 3GS being locked to Rogers?
This phone is a jailbroken iPhone 3GS (model MC143C) running version 3.1.3 (7E18) and locked to the "Rogers 5.0" network. If it helps the modem firmware is 05.12.01.if there are no real solutions, I still have 2 months left on my warranty. Would Apple fix it or give me a new one if I un-jailbreak it?
Still struggling to get to grips with my new iPhone 4S....Reading the User Guide it says "to turn Cellular Data off go to Settings/General/Network then turn Cellular Data off".The only problem with my phone is that "Cellular Data" does not appear in the Network screen. However "Mobile Data" does.is it the the same thing?For cost reasons I would like to be in control of when I use the internet and already I have inadvertantly incurred charges without being aware that I had gone on to the internet.Will selecting "Mobile Data" to "OFF" solve my problem.

I was updating my iphone's software this morning, I believe there's a new system or something - my phone told me to update, while I did so my phone stopped working, the only image I can see right now is a picture telling me to connect to ITunes. ITunes isn't picking up my iphone either and its stating the software server could not be contacted.

Last night I finally installed 3.2.1 in my 3GS. I then synced it with my brand new MacBook Pro.Now nothing works except what came with it. Any app I try to open kicks me back out to the home screen.I have tried turning it off and on but that has done nothing.Is there anything I can do to fix this?
View 6 Replies View RelatedMy best friend and I both have iPhone 4s' and have been using iMessage since we got the phones back in December with no problems. Last Wednesday, we updated our iPhones to the newest iOS 5.1 update. The following day, she had turned her phone off because her wifi was acting up and wouldn't send her iMessages. She fell asleep before turning her phone back on. When i sent her a text, it was saying "sent as text message" under the couple texts I had sent her. When she woke up and turned her phone back on, iMessage wouldn't work and continued to send as texts. The next day she found that if we turn our "send as SMS" off, iMessage started working again. The same thing happened again last night and we tried the "send as SMS" thing again and it's still not working. We have tried everything and can't figure out how to get iMessage working for us again. This problem didn't ever occur until iOS 5.1 update

View 1 Replies View RelatedMy IPhoneS stopped working right after I did the latest update which was yesterday. Now, the phone does not work at all. When turned on, the screen shows a picture of USB cable pointing to the ITunes logo. I have tried just about everything, and cannot get it working. It's like it is frozon. My ITunes does not recognize my device. Cannot dial out either. I desperately need to get it working.

A recent update (7.1) for iPhone has completely crippled my 4s wifi, it won't switch on.. most of the time I have no 3G either & the phone is mush slower than before. I've tried the online fixes ( reboot & reset) I've been to my local Apple Store, who inform me the phone can't be fixed & is out of warranty. I still have 6 months to run on my O2 contract...... is there nothing I can do about this. Â
View 2 Replies View Relatedthe auto-updating of apps stopped working on my iPhone (4s/iOS 7.1.2). Not sure if that's a coincidence but it seems like it stopped working immediately after iOS 8 got released to developers (on June 2), as if somehow the App Store got configured differently, preventing devices running iOS 7 to auto-update apps. Auto update of apps used to happen at night here, most likely when the system has been idle and plugged in for a while, but no more. I find apps to update every morning, nothing has been done automatically.
ps: I did de-activate reboot and re-activate auto-update, no change.
updated my new iPhone 6 plus to 8.1.1 and the maps app won't work just crashes everytime it's opened so everything that uses a link to it eg:- find my friend, find my phone, Argos app facebook if someone puts their location on which shows the map all crash. And my safari just crashes when ever it likes.

View 14 Replies View RelatedSo I got my first ever iPhone and it's the iPhone 4. I have the 200mb plan and I plan to switch cellular data off most of the time if wifi is available to avoid overage. Thing is, with cellular data off, I can't do certain things (ex. Receive picture messages via the Messages app) unless I turn on cellular data. So as long as wifi is available, will my phone still use up cellular data even though it can get data off the wifi? Thanks.
I apologize if I failed to look up any threads on a similar subject. I did a quck search but they weren't really what I was looking for.
when i turned OFF the cellular data network, i can't receive/sent message/make a calls...i do same on my iP4 before,but it doesn't have any problem like this..

My partner is in the US for the week. She has turned off Cellular Data in Settings → General → Network to avoid exorbitant data costs yet when I reply to her SMS messages my messages are sent as iMessages, which she can't now receive. She's also turned off iMessage in Settings → Messages but so far my messages still default to iMessages instead of SMS. She's having this problem with other people as well, no doubt because their iPhones keep trying to send her iMesssages.
I know that I can turn of iMessage on my phone and that lets me successfully send her SMSs but I wonder if there's something she can do at her end to make SMS the default for everyone who is trying to reply to her. I've also tried Settings → General → Reset Network Settings but it hasn't solved the problem.
