Phone call wifi conflict

When my iPhone 4s is connected to my work wifi I can't make or receive calls to or from mobiles? Any ideas why this might be.  My colleague has the same model phone and does not have this problem.

To my knowledge, there is no setting that would cause this and phone calls should not be impacted by WiFi connections one way or the other. (Messaging is another matter, as is FaceTime.)
Try a reset: Simultaneously hold down the Home and On buttons until the iPad shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the iPad back on using the On button. In some cases it also helps to double click the Home button and close all apps from the tray before doing the reset.

    Most of the current Apple Intel based computers are comparable in CPU speed. I don't think it is so much the model of laptop as it is the memory, and storage capacity of the machine. If you are going to use FCP on a regular basis, perhaps as a professional or semi-professional, then you should think about the maximum memory and a very large capacity internal disk drive. For instance, one hour of finished compressed video will take up about 1.5 to 2Gbytes of disk space. If you add up the raw footage and still imagery and audio, you'll use up your disk drive capacity real quick. So a hard disk on the order of 750Gbytes @ 7200rpms might be good for video editing. 5400RPMs might be slow to rendering times. Rendering a video might take up a lot of memory so more memory is better e.g. 8Gbytes.
    As a rule of thumb, once you get to about 80% of your disk drive or memory you'll see degradation of performance.
    You can check out macsales.com. THey have a menu system that will allow you to pick and choose from various alternatives. BTW, it's been said that although Macs are typically spec'd at a certain memory size, macsales.com found that Apple computers will actually support higher memory levels. That is, if 4Gbytes are spec'd, some machines support 6Gbytes. macsales.com will provide the guidance for you.
    You might also consider buying an external disk e.g. 500Gbytes to carry around with you for back-up or transport to another machine.

  • TS4069 used to be able to surf the web and be on a normal cell phone call at the same time without the use of wifi. now i need wifi to do this

    used to be able to surf the web using 3G and be on a cell phone call. Now it only works when i connect to wifi...WHY WHY WY

    Verizon is not a GSM carrier. Verizon and Sprint are CDMA carriers that have also recently adding an LTE (4G) network. The iPhone 5 is a combination LTE/GSM/CDMA network compatible phone.
    ATT and T-Mobile are GSM carriers. ATT has also recently added an LTE network.
    If you were able to talk and surf the web on Verizon's CDMA network with your iPhone previously, that was some trick which is not supported with a CDMA network as is supported with GSM 3G networks.

  • Since upgrading my phone to 6.0.1, I'm using way too much data. I believe it's the podcast app that's not loading shows while I'm connected to wifi. I have the 3g turned off for podcasts??? also after a phone call or an alert it starts playing a podcast?

    I've also had the same issues, after upgrading to IOS 6.0, the apps in my iPhone 4 were crashing and the battery life run out very fast.
    The only solution worked for me was to remove all mail accounts (Exchange/Gmail) from my iPhone (in settings) and then add them back.
    The crashing were stopped! also the battery was back to normal.
    I found the solution by first looking at the crash logs (in IOS 6). you can find them at Settings -> General -> About (at the bottom of the About menu you will find the option that opens the logs).
    There i saw many logs about Low Memory crash. 99% of the logs were pointed that the largest process (use the most memory) during the crashes is "dataaccessd".
    I search in the web and found that this process is a deamon process that reponsible the Mail accounts (like Exchange/Gmail) and contancts list.
    I've installed the app "System Status - activity monitor" which shows important system info like CPU usage, Memory usage and running processes.
    Before apply my solution (deleting the mail accounts) i saw that the CPU usage was very high which consume the battery very fast. Also i saw that the memory (RAM) was run out.. which probably what cause the crashing..
    After deleting the mail accounts (at Settings -> Mail, Contacts, Calendars) i check again with the System Status app, and saw that the memory and CPU were back to normal.
    Adding the mail accounts back, still everything work ok
    Hope this solution will help you too,
    Enjoy!

  • HT3406 After the steps suggested, does it mean i can "remove" the SIM card and use my iphone via WIFI? i can browse the internet but cannot make phone calls right?

    Is the wifi card a build in in ipod/ipad? yet build in on SIM card in iphone?

    But on WiFi, could I still use Skype to make a phone call? I have a camera adapter for the iPhone 4 and would just use it as a camera and to play music after I upgrade to a later versionof iPhone. Am I correct in assuming that I could still do everything except connect through 3G?

  • Hello, I have a problem with my iphone 4 battery, it looses 20% over the night with wifi on and without receiving any phone call or notification. It also uses 1 or 2% each time I check my iphone even if it is just to check up my messages. Is it normal?

    Yes this is fairly normal. When you have wifi on the phone, it drains the battery life of the device.
    Here is an article that has some tips that you can follow so you can modify the settings on your device to extend it's battery life to the fullest.

  • Can i use my itouch to make skype phone calls without wifi.

    Can i use my itouch to make skype phone calls away from a wifi source just like a conventional mobile phone.

    No. The iPod does not have a cellular connection. Thus, an iPod without wifi can't connect to the Internet

  • I have full signal and have wifi but I'm can't send messages or receive them. I can't make phone calls either.

    HI
    I have full signal and have wifi but I'm can't send messages or receive them. I can't make phone calls either. it picks and chooses when I can receive them and make calls. It only works everytime I turn my phone off.

    Try turning on Airplane mode for a little bit (20-30 seconds) and turn it back off. see if that doesn't allow you to re-connect.
    In my current project my office receives no signal at all. I have to do this almost every time I leave the office in order to get a signal.

    Why do my incoming phone call ring on my wife's phone as well as mine?

    That is a new "feature" described in Connect your iPhone, iPad, and iPod touch using Continuity
    You can turn it off by going to Settings > FaceTime and changing "iPhone Cellular Calls" to off.

  • I am receiving my wife's incoming phone calls to her I-Phone

    I am receiving my wife's incoming phone calls to her I-Phone. We both have I-phones. How do I fix this?

    Fist of all...
    Dont share Apple IDs.
    Every user should have their own...
    That being said...
    Go to Settings > Facetime > Iphone Cellular calls (Turn this off)

  • TS1398 Why I lost my wifi connection during i make a phone call ?

    Why I lost my wifi connection during i make a phone call ?

    If this is a cordless phone that you are taliking about, it is operating on the same frequency as your wireless network, and the phone is creating issues. Unfortunately, this is a common problem.
    A potential solution might be to move the phone as far away as possible from the AirPort Extreme and your computers, or changing the channel on your AirPort Extreme to try to find more clear airspace.
    In my case, I had to go out and find new phones that operated at higher frequencies to solve the issue that I was experiencing.

  • Wifi, phone calls, nothing works after IOS7. I got this phone a week ago!!!

    The title says it all.  I got this phone (4S)  as a replacement for a damaged one.  I upgraded to IOS7 straight away and can now not make phone calls and my wifi is blanked out.  What the **** are you people playing at?  I need this thing to work and you come out with an operating system that doesnt do fundamental things like make phone calls or download data. 

    This indicates corrupt files.
    A restore should resolve.
