I know this seems backwards but I have a very good reason. my cellular data is unlimited and my jetpack Mobil wifi from another service is not. I keep both on while driving to enable consistent Internet for Internet radio for instance.
View 1 RepliesAT&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.

So 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.
Even though I have an unlimited (?) data plan for my iPhone4 from Sprint, unless I am mistaken I would get faster transfer rates using wifi instead of their 3g carrier signal. Is that correct and if so can I set my iPhone4 to use wifi preferably if available or does it do that already?

Recently the data on my 9700 will not switch from WiFi to cellular. If it's attached to a WiFi network, everything works fine. However when I leave that network and the BB needs to use EDGE/3G it does nothing. It will not even attempt to transmit or receive unless I do a battery pull. If I leave WiFi off, everything works fine. It is now running OS v6.0.0.668 by AT&T. I just updated to this OS in hopes that it would fix the issue, but no luck.

i just purchased my iphone, and i found my cellular usage is increasing while i was on wifi the entire time? i thought i'm completely off the cellular network while connected to wifi, but this doesn't seem to be the case.
View 1 Replies View RelatedI am using Nexus5 (Android 5.1). Actually, my network provider has charged me for cellular data usage which I never did. In-fact, I haven't subscribed to any data pack and was charged heavily. I always use internet through WiFi.
My data usage widget is displaying 0B data usage, but my network operator is insisting that the data has been used by the device.
I want to understand if this issue is really due to my device.I see different cellular network icons on my device :-
- Exclamation mark in cellular network when WiFi is disabled (I never enable cellular data)
- R sign in cellular network (cellular data is disabled and i am not in roaming)
- No R or exclamation sign (both WiFi and cellular usage is disabled)
I am not able to understand,Is my cellular data usage is really due to my device settings or is due to some issue by service provider.
Is it that the device is indeed using cellular data despite of the fact that cellular data option is disabled and it never shows this usage in data usage widget.
I observed that when I use Wi-Fi, then exclamation sign from cellular network is removed, does that mean that the cellular data is also used and that's why my service provider has charged me?
Can I find an IPhone that is no longer connected to a phone service, but which is still connected to our WiFi network?
View 4 Replies View RelatedMy wife is on a school trip to the US. Meanwhile, I am at home in Canada. I am texting her, but I found it odd she never replies and vice versa. So, she discovered that her iPhone (latest iOS 5 release) keeps trying to send the message as an iMessage. It is not reverting to SMS after a given time, as it should and as I have seen it do before. I have tried it now also and my wife only receives my messages when she has a wifi connection (she does not have data roaming enabled). It seems like my iPhone too continously tries to send the message as an iMessage and it does not switch to SMS after a certain timeout time. The message that the iPhone continously tries to send as an iMessage never fails, however the status does not change until the next time my wife is in wifi coverage and the message is delivered.

My phone (galaxy S5) worked very well with my carrier (Videotron). I had a problem connecting to the data so I called videotron and they told me to come in the store to fix it. Not really knowing what i was doing and being a little bit impatient I was looking through the settings of my phone, trying to figure out what was the problem, when I found the Activate this device tab. I then proceeded to clear my "cellular data'' by pressing the 3 dots on the top right corner. After this, it said ''invalid SIM card'' and I've reset de device twice, went to the videotron store, contacted Samsung. Still no solution.
View 5 Replies View RelatedI've had my phone since April and has recently started to experience a lot of problems with the handset. I'm best mentioning that my technical know-how is very limited in terms of phones, but I've accepted the fact I'm going to have to run a factory reset on my phone. So the problems I'm experiencing:- All of a sudden, apps start crashing one after the other. So much so that I can't even turn the phone off properly and just have to hold the power button down until it goes off itself.- Sometimes it just freezes, and when it does, it rapidly drains the battery.- Other times it just randomly decides to turn itself off (this has happened during the night resulting in me sleeping in for work because my alarm has failed to go off!)- When apps have crashed and I've had to turn it on and off again, all information stored (ie. texts, photos, Twitter feed) after the 16th October is gone!I've even went on Kies Air to start transferring photos, videos, etc. to my laptop, but even that keeps crashing, meaning it constantly disconnects from the laptop. I cleared out a lot of old apps I don't use anymore, but they reappear when I turn it back on, resetting back to pre-16th October like I mentioned.

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.

Android hasn't been syncing saved network info for me since I was on my Note 2 6 months ago. So now I have all my saved Wi-Fi info on the N7 (which never leaves home), and it never synced to my N6 or G3 before that.
Any ways to troubleshoot this?? I do have app data checked to sync on both the gmail accounts on my Nexus 6.

I used the S Memo app on my S3 but I can't find the same app available for the S5. Does it been replaced and what the replacement might be called and whether I can restore data from S Memo back into it? I backed up everything from my S3 using Kies3 so can I selectively restore S Memo into the S5?

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.
