Cellular data being used while connected to WIFI and not in standby
I am connected to my home WIFI on my iphone 4, but while my router is not connected to internet (so I should not have internet on my iphone), I noticed I am still receiving push notifications,
I finally read here that while on standby, wifi is turned off and 3G is used, ok.
now here is the problem, looking at the General>Usage>Cellular Usage, even if I am not on standby and I am using the phone, I have data usage (sent and recieved), I reopen the Celluar Usage and see the numbers are constantly increasing, and more strange is some (not all) of the push notification do come through (eg in my case for an app called FavFriends),
another friend of mine has a simillar problem on iphone 4s.
what is this celluar usage in the background?????
from what I knew so far, iphone should not use the 3G if wifi is connected, eventhough there is no internet on that wifi,
so in my case, if iphone is actually detecting no internet and switching to 3G, I should have internet on all apps (safari, etc..) which i dont, just data usage increasing with no internet in any apps (that is a 3G usage which is limited more than even when on standby),
and if it is not supposed to switch, it brings another question, that if 3G is used when wifi connected (with no internet), are there any background 3G usage (push notifications, etc), while wifi has internet and it is supposed to utilize the wifi internet?
so basically, I was under the assumption that 3G would not be used unless wifi is disconnected, regardless of internet access, and I dont find anything that says otherwise.

Why am I being charged for data when connected to wifi AND not using my phone?!
WHY am I being charged for data that I'm not using? At times when I'm asleep AND my phone is connected to wifi?! This happens at really specific, alternating times like 9:54 pm every day, or 12:01 am, 6:01 am and then 12:01pm and 6:01pm. When I called I was told "maybe your wifi at home is disconnecting" or "maybe your phone is connecting to atnt or sprint". It's not possible that my phone is disconnecting from wifi every six hours on the dot and, at that exact time, I'm always using data. I find it hard to believe that I live in a HUGE city and my phone magically connects to other networks and I NEVER notice this. Verizon is full of LIARS (and maybe’s) and I'm not convinced that these data charges are a coincidence. I was told to turn off my cellular data to see if the problem resolves itself. Why should I alter my daily life when Verizon is clearly the one with the issue? I hope there's a class action lawsuit because Verizon is trying to get over on everyone! I need answers!
Hello NotHappy101,
I think it's quite odd that your data usage is at very specific times. We can certainly take a closer look. Please reply to my Direct Message, so we can get some additional details.
Thanks,

Is it possible to use iMessage only over WiFi, and not use cellular data?
When I go to Settings -> Cellular, there is no toggle for messages. Is there some way I could selectively disable cellular data usage for messages? That is, I want messages to be sent with SMS instead of data even if cellular data is available, but not if WiFi is available. If WiFi is available, then I would want the message to use the WiFi.
My situation is that I will be traveling internationally and will have a plan that allows unlimited texting but limited data. I don't want to have to toggle iMessage on and off every time I connect to WiFi to prevent data use with messages!
Thanks for any help!The only option you have is to turn off cellular data completely. You are correct, there is no setting for cellular data for messages. If you toggle iMessage off/on multiple times, you will end up with problems, since others will not know if you have iMessage off/on, and will continue to try to send iMessages to you. Also, you may find you will have problems with iMessage activating again after turning it off. iMessages do not use very much data, but if you are using data for other reasons, that could use up the limited pool of data you mentioned

Cellular data being used even when at home with Wi Fi
I notice that sometimes (actually pretty often), my cellular data is being used even if I'm at home with Wi Fi available. At this rate, my monthly amount of gigabytes is getting used up pretty quickly. It's gotten to where I have to go into settings and turn off cellular data whenever I come home. Has anyone else had this problem?
You must be losing wifi sometimes. The iPad uses wifi, unless it's not available. Then it switches to 3/4G. Turning Off cellular is the best procedure.

Can my iPhone4 use be connected to WiFi and still be connected to the 3G network at the same time?
My iPhone is on the Bell network, along with 3 other iPhones in my household. We have WiFi and the phone indicate that they are connected to the WiFi when we are in the house. However, my bill from Bell indicates several instances where the phones (all 4 at different times) are connected to the 3G network for 24+ hours at a time. Additionally, it shows the phone connected twice during that time period (as though there were 2 different sessions at exactly the same time, but with differing amount of data connected)
The explaination that Bell gives me is that there are 'minimized' applications still working on 3G even though the phone says it is on WiFi, and that each of these opens its own 'connection'.
My understanding of cell technology is that the phone can only access one method of Internet connectivity at a time, and that it can be explained as a 'pipe' or 'straw' carrying connectivity and all of the data. I have never heard of a phone that can access two different types at the same time, nor one that uses separate 'sessions' at the same time of either type of connectivity.
I would assume that I turn on my phone in the morning and I am in my house, it indicates WiFi, so I can browse the web, collect my email and update my Facebook on that 'session' that lasts 4 hours until I leave the house. Now my 3G kicks in and the email that I still have open now collects through the opened 3G session, as well as the page I left open downloading something. When I get to work and enter my WiFi area there, the session would then collect my email through WiFi again, and my download as well.
If this is incorrect I need to know.
Can someone help?Keep in mind that the reporting of data usage is not real time for any carrier. The time stamps of when data is used are essentially meaningless.
That being said, the device is always connected to the cellular data network unless the user actually turns off cell data. It is designed to use Wi-Fi when available as that is typically the faster network.
When the device is in sleep mode, it will use cellular data as the Wi-Fi antenna is turned off to save battery life. The only way the Wi-Fi stays on in sleep mode is if an app is actively using data over that connection, like Pandora or similar apps streaming audio. -
Date Format issue while Connecting to Oracle8i and Oracle10g
Hi All,
While playing around with JDBC drivers, I came across this weird issue. I have a Local machine with Japanese Locale and I have 2 Database Servers that too with Japanese Locales and Oracle 8i and Oracle 10g each. Now, I connect to these database using JDBC drivers for 8i and perform "select sysdate from dual". Then, m getting dates with 2 different format. While 8i being returning Date with 'DD-MON-RRRR' format, 10g returns date with 'DD-MM_RR' format.
Initially I thought it might be because of some VM Locale thing but when I connected to 10g DB from 8i Oracle client, this behaviour did not changed. Which mean in this case also the date format returned ny the query was different.
Guys F1! F1! (Help! Help!) Appreciate your help to understand this process. Links and suggestions welcome... :)I guess u did not read the whole content. I mentioned this but the difference in behaviour with respect to JDBC drivers made me post this in Java forum.
As I mentioned, it has something to do with the jdbc driver or oracle server itself. Agreed, but what that "something little to do" is the maiin question.
I mentioned that I want to understand this process about how JDBC driver works with Client VM specific Locale settings while interacting with Oracle Database.
Don't you think it could be interesting to know, what it is which brings this difference in results. Its all about clarifying the small bits & pieces which stays unanswered if one overlooks. Its own perception, I felt like asking question, no offense right! -
MB Air cannot see TC 1T '09 while connected via WiFi and Ethernet.
I have a TC 1T 2009 7.4.1 that I have set up successfully with MB Pro and MB White. However I cannot set it up with MB Air v.1 which is connected to TC via WiFi AND Ethernet cable. Internet is fine (Safari) but no TM - when I run APU 5.4.1 it cannot discover the TC it is connected to.
I tried connecting after hard-reset (poke/power on), it would see the TM but then hang forever reading the configuration. So I set it up with MB Pro and MB White and both are now working fine with TC/TM. Then I tried MB Air and it failed.
The TC is connected via ethernet to Sagem router (bridged mode) which supplies WAN and DHCP, it has its own WiFi as well.And by the way, Hi Everyone, how rude of me not to greet you in the post.
Thanks for any help! -
Data being used even on WiFi? Lumia 1520
I recalled this being an issue with users in the past with other devices until GDR3 fixed this. Somehow on my Lumia 1520 I used over 3GB of "Media Streaming" data according to Data Sense in the last 2 weeks. I don't see how this is possible as I'm connected to wifi 95% of the time. If I'm not connected to wifi I don't do more than send texts, a few instant messages or emails. I don't stream videos and I have both Xbox Music and auto upload of pics and videos turned off.
This concerns me greatly as I am now 680MB away from hitting my 6GB limit and I still have 9 days to go. Overage charges are BRUTAL on my carrier (Rogers). I assume that even when it shows wifi as connected it's actually not connected. I will now have to disconnect and reconnect to wifi to play it safe before I stream or view any online media with my 1520.
Anyone else seeing this issue or have any suggestions?

Once WIFi connects it will always override the cellular a data connection unless
You do not have the option to keep WiFi alive under lockscreen set
You are under lockscreen
You are not connected to a charger
It is far more likely you did not notice you were on Cellular data at some point. And 680 MB in 9 days when (by your own words) you are on Wi-Fi 95% of the time should not be a problem. if your usage pattern is as you say it is (with sending SMS not even being on data anyway.
Well on average I use about 3-4GB a month previously with my Lumia 920. With my Lumia 1520 I have reached 6GB in 3 week with still just over a week to go. I've had to turn off my data completely to keep myself from overage charges. My concern is that I don't understand why data is being used while connected to wifi at home. If I have my device setup to connect to wifi automatically at home, and as you suggested, I have it set to stay connected to wifi after the screen times out.. then why is it still using data over wifi? And to make it worse the phone tricks me by showing me an active wifi connection in the status bar. So I'll be at home, comfortably surfing the next, streaming media while under the assumption that I'm connected to wifi since it shows I'm connected to wifi but in reality I'm using data. Why do I have to manually disable wifi and re-enable it just to feel assured I'm using wifi? I never had to do this on my Lumia 920.
So far in the last 4 days I've only witnessed my phone hold connection to wifi over a period of several hours twice without me manually needing to disconnect and reconnect again. But sadly, there was no obvious answer to why it worked those 2 random times that it did. Is the issue my router? Do I have a botched device that needs replacement? I've consulted others on WPCentral's forums and found several others reporting the same issue though it doesn't appear widespread. I just need to know if I need to up my data plan to 10GB to cover myself from constant overages. -
I have an iPhone 4s, but wifi the option is greyed out. The wifi stopped working on it months ago. Now I wanted to erase all content and setting from my old 4s and it will not connect to the internet, because the cellular data is no longer connected, since I bought a new iPhone 5c. I can't erase my phone by pluggin it into my Macbook Pro, since I can't disable the "Find my iPhone" App without internet. How do I erase all the data and setting on my 4s without connecting to the internet? It is running ios 7

Too bad my 4S is 2 years old. Wifi is dead. I had to upgrade to 5S, but 5S is soooooo much faster than 4S so it's kind of good outcome. Without the 4S breaking down, a stingy person like me would have never upgraded the phone. -
HT4203 will i be charged if i leave the cellular data on but also keep the wifi on as well?
will i be charged if i leave the cellular data on but also keep the wifi on as well
When wifi is being used your phone will not use cellular data. When wifi is no longer being used (ie out of range, wifi is turned off) then your phone will use cellular data.

if I'm overseas, and I use iMessage not connected to wifi, and I'm messaging someone who has an iPhone as well with ios 7, will get charged SMS/mms fees?
No, but cellular data will be used at whatever international roaming rate you carrier charges for data in whatever country.
Exchanging iMessages requires the same thing as email - an available internet connection. SMS/MMS is completely separate from iMessage. -

I have the Droid Razr Maxx HD and I cannot send multimedia messages while connected to WiFi.
I have a mobile data "signal," but need to disconnect from WiFi whenever I want to send a multimedia message, including a group message. I can receive multimedia messages while connected to WiFi, sending them is the only issue. Is this a common issue? And is there a fix for it?
It's very inconvenient as my phone is almost always connected to WiFi and I often use group messages for work.Don't believe someone who tells you that you have to turn off WiFi - I FINALLY got someone who knew what they were doing at VZW - and she had me do the following - and VOILA - it worked! This is a known issue and level 2 support has access to many similar cases
Call VZW Tech support and tell them you want them to do the following:
1. You turn off your phone
2. They "Refresh the network on the voice and text side"
3. They "Sync network with billing"
4. You turn your phone back on
This solved my problem...... -

I have a verizon iphone 5c and I took out the SIM card just being curious and put it back in, now I can only use my phone on wifi and I can't use 4G or LTE strictly wifi. How can I fix this?
Have you tried resetting your device by pressing and holding the Home button and power button until the silver apple appears? If that doesn't work, try resetting the network settings. Settings>General>Reset>Reset Network Settings.
If that fails, you may possibly have damaged the SIM. Verizon will need to give you a new one.
Best of luck.
