How To Set Up An iPhone DUN Internet Connection

00 morefeatures tethering   How To Set Up An iPhone DUN Internet ConnectionWith the dawn of the internet, computers and modern telecommunication technology, the term “working” has shifted from what it was several years ago. Nowadays, working is not always identical with sitting in a physical office from 9 to 5. Any place can serve as a virtual office. All you need is a mobile computer and a good internet connection.

WiFi hotspots have become common hang out places and we can find these spots almost everywhere, from the big international airports to your friendly neighborhood coffee shops. But they are not really everywhere and they can’t follow you anywhere you go.


There are times when you are on the road and nowhere near WiFi spots but you still need an internet connection. These are ideal times to use the internet connection provided by your mobile phone provider using your phone as a modem.

The process is known as wireless DUN (Dial Up Networking) – or tethering, utilizing Bluetooth to connect the gadgets. And if you use an iPhone, the iPhone DUN set up process is very easy.

On The iPhone Side

There are two steps needed to set up an iPhone DUN internet connection: on the iPhone side and on the computer side. Let’s start with the first one.

  • Open your iPhone “Settings” and go to the “Internet Tethering” option. It’s buried a little deep inside “Settings – General – Network – Internet Tethering“. This setting is off by default.

  • If you switch the tethering on, your iPhone will ask you to turn on your phone’s Bluetooth connection (if it isn’t already on). If you choose not to turn it on, the tethering will only be available if you connect your iPhone to your computer using a USB cable.

  • Click on the Bluetooth service icon on the menubar and choose “Set Up Bluetooth Device“.

To Tether Or Not To Tether, That’s The Question

I have to apologize to Linux users for not including the OS here. The reason is I currently don’t have access to a Linux machine. But the basic process should be the same: pair your iPhone with your machine, and connect to the net using your iPhone as a modem.  If the process differs in any way, please do let us know in the comments.

But please note that due to financial reasons, tethering (using an iPhone or any other mobile phone) is not for everybody. You have to check whether your cell network subscription includes internet data, and if it does, how much is it? Some cellular networks impose crazy price tags for their internet connection. Make sure that your wallet won’t burn at the end of the month before you try this method.

Another thing that I have to point out is even though I’ve tried the method successfully (using the iPhone 3GS under iOS4, Mac with Snow Leopard and a Windows machine under Windows 7), the steps might be slightly different and the results might vary if you use different combinations of hardwares and softwares.

If everything goes smoothly, you don’t have to worry about an internet connection anymore. Between your home connection, the hot spots and your office’s internet connection, you will have your iPhone’s DUN Internet connection to cover you when you are on the road.

I do not have tethering as part of my cell phone plan, but I’m curious as to what kind of speed you get by accessing the Internet this way.

Is this an official feature of OS4? Or is this a jailbroken iPhone? I used to be able to tether before upgrading back when 3.1.2 came out, but since then it hasn’t worked for me.

No, it’s not jailbroken iPhone. I’m using 3Gs and official iOS4; and as far as I know, this feature is available since iOS 3. But there are some carriers which disable tethering unless you upgrade your subscription. (Even though the workaround is just a search engine away).

Well, it depends on the speed of your cell provider network. In good condition, I could get 3G speed from my provider and the download speed is up to around 50-60 KB/s.

I have an iPhone 4, but I do not pay the extra $15 a month for a tethering plan. I’ve seen this in the iPhone settings already, but I had no interest in racking up a huge bill by enabling and finding out that means I signed up for the most expensive data plan. Can someone confirm that I need the plan that already includes tethering to do this? I don’t want to try it myself, for the already enumerated reasons.

It depends on which cell operator you are subscribing to. Mine just practically unlock the door and let us do what we please :). But yes, some operators require you to pay extra for the feature.

I agree this is NOT dial up networking it’s plain old tethering. ‘Dial-Up’ is half the clue. Nothing is dialled the connection is already established. Misleading, dissapointed
