Smartphones, in spite of their small form factor, pack in a lot of power and functionality. And combine that with the <i>unlimited</i> Internet data plans that are now available from most carriers, you get a powerful mobile device that lets you check email and surf the Net. Sometimes you may run into the limitations of the small screen and the lack of keyboard/thumb-board. That's when the Bluetooth functionality and a laptop can come in handy. So the next time you're on vacation or on a business trip and want to reply to your emails, you can connect your laptop to the Internet using your Smartphone as the modem.<br /><br /><img src="http://www.smartphonethoughts.com/images/Kris-Jan05-XPBT30.jpg" alt="User submitted image" title="User submitted image"/> <br /><br />The following <i>How-To</i> article takes you through the steps required to connect your Smartphone and laptop using Bluetooth, so that the laptop can access the Internet using the Smartphone's data plan. <!> <br /><br /><b>Pre-Requisites:</b><br />- Smartphone with Bluetooth [e.g. Audiovox SMT5600, Motorola MPx220];<br />- Windows XP Service Pack 2 based laptop with Bluetooth;<br />- Internet Data Plan with the carrier, unlimited data plan is preferred.<br /><br />Please note that for this step-by-step guide the Microsoft Bluetooth components are being used. These come standard with Windows XP Service Pack 2. In case you are running a different Bluetooth stack [e.g. a vendor specific one], then some of the desktop based screen shots may vary. But the overall steps and the sequence should be the same as illustrated by this guide.<br /><br />Before you begin, please verify that the Smartphone's Outlook mailbox and Pocket Internet Explorer can connect to the Internet. Perform mailbox sync or browse to a Web page on the device. If you are unable to connect, then verify the settings under <i>Start->Settings->Data Connections.</i> You can use the <a href="http://www.mywindowsmobile.com">My Windows Mobile</a> Website to configure your device. <br /><br />In case you are using a Bluetooth dongle on your laptop, ensure that the dongle is plugged in and Bluetooth is enabled on the laptop.<br /><br />Let's begin the configuration process.<br /><br /><b>Step one: Launch Bluetooth manager on your laptop.</b><br /><br /><img src="http://www.smartphonethoughts.com/images/Kris-Jan05-XPBT2.jpg" alt="User submitted image" title="User submitted image"/> <br /><i>Figure 1: On your laptop, click on the Bluetooth icon in the system taskbar and click on the menu item titled "Open Bluetooth Settings".</i><br /><br /><img src="http://www.smartphonethoughts.com/images/Kris-Jan05-XPBT14.jpg" alt="User submitted image" title="User submitted image"/><br /><i>Figure 2: In case you do not see the icon in the system taskbar, try the Control Panel.</i><br /><br /><img src="http://www.smartphonethoughts.com/images/Kris-Jan05-XPBT3.jpg" alt="User submitted image" title="User submitted image"/><br /><i>Figure 3: This is the Bluetooth settings applet on your laptop that will help you establish a connection with a Bluetooth Smartphone.</i><br /><br /><b>Step two: Make Smartphone discoverable via Bluetooth.</b><br /><br /><img src="http://www.smartphonethoughts.com/images/Kris-Jan05-XPBT36.jpg" alt="User submitted image" title="User submitted image"/><br /><i>Figure 4: On your Smartphone, click Start->Settings->Bluetooth.

You may also need to tweak some of the options. Since I do not have an ISP number and account handy, I cannot lay down the exact steps.

Thanks for posting this well illustrated how-to!

I was struggling through this the other night (my MPx220 is my first BT device), and now I see I was 80% of the way there! :)

I'll try it the rest of the way tonight.

This is the most common error I get. Next time it comes up, I will try surfing with the Smartphone first and then redial from my laptop to see if it solves things. If so, it will be much easier than my current process of rebooting and kicking everything. :wink:

I am running into that error repeatedly tonight, regardless of whether or not I reconnect from my smartphone. I saw some posts on howardforums that said the solution was to use the connection string that Kris talked about at the very end.

Are you on T-Mobile or Cingular?

If you are with Cingular or with a carrier that requires username and password for the Internet connection, then try putting them in Figure 28 or Figure 30.

I tried and tested this with T-Mobile and different carriers have slightly different registration process. :-( Hopefully we will identify all the problems in this thread and make it easy for future users.:-)

Hey guys I have a very important question. Im with cingular now….will they charge for using the connection with the laptop? I was told by two different reps that they charge extra for connecting and using the internet connection with any other device than the 220 itself. BUT! How the hell will they know? Is this true or are they just trying to scare me? I know when I was with t-mobile I use to do this almost everyday. I’d love to be able to use my phone as a modem again.

Good point. I believe the carriers can find out that you are using your Smartphone as a modem. And therefore can charge you extra.

Regarding Cingular, not familiar with their data plans. And don't know whether or not they will charge extra.

Thanks Kris,

I had tried putting in the username/pwd in those boxes (although maybe I just had it wrong?) but again, it was to no avail. I think I might call Cingular about it, because I also would like to verify that it won't cost me extra. I'd better call at least 3 times though, because I've consistently gotten different answers from different reps (on other issues)!

But by all means, if someone knows how to connect from a Cingular phone, let me know!

Do let us know the info you find out from Cingular rep(s). ;-)

And click here (http://www.smartphonethoughts.com/forums/viewtopic.php?t=7092) for the Cingular settings: the username, password, APN etc. Thanks to encece for posting the info.

I noticed that the APN, username and password are all in uppercase, could that be an issue. :?

Well, I only talked with one rep from Cingular today, but he confirmed that they have separate data plans for using your phone as a modem, and they start at $20 for 5MB or so, up to $80 for unlimited. That was enough to convince me that my issue was because I was purposely being blocked, and I don't really want to incurr extra charges. :)

Oh well, I dreamed it was possible once... now I have to figure out what else I'll use my BT dongle for my laptop for. :)

I have used my Smartphone as a modem via usb for over a year now with T-Mobile's $9.95 Internet Pro or whatever they call it. Not the $19.95 plan.

It's usually a week here and a week there when I travel but during those times I've spent hours connected and transferred many many megabytes of data.

Never charged anything extra.

I signed up with AT&amp;T (SMT5600) last October, just weeks before Cingular bought them.

Last month, I got the SX66, and was able to switch over to Cingular without problem. I also bought their unlimited MEdiaWorks for $20/month. When I used KK's recipe yesterday, I was able to connect to the net using the BT on SX66. However, I was not sure whether I would have to pay for 'data' since I only had MEdiaWorks. So I downloaded the Cingular's Connection Manager and was able to use that to connect to the Net via BT (using MEdiaWorks settings) several times in a couple of hours.

When I tried to connect later last evening, I would get a "No Connect" sign on the SX66 (an X next to the antenna instead of bars). Tech Support told me that the Connection Manager does not support the SX66, even though the SX66 has the ability to be used as a tethering modem! I guess they found out from my cellphone number that I was 'cheating' and blocked it.

So I returned the phone, and was able to get back to AT&amp;T with my old plan that includes $25 unlimited mMode on my SMT5600, because I had the SX66 for less than 30 days. Again, I am able to connect to the net dialing *99#, and no username or password. I have these three questions:

1. By dialing this way (*99#) am I going through mMode or using data minutes that I will be charged for?

2. Is there a way to set up the connection so I connect my laptop to the net via SMT5600 using mMode if the *99# does not go through mMode?

3. I tried to connect to my ISP (BellSouth) putting their phone number, my username and password, but I get the message: Connection Failed. Any thoughts on what am I doing wrong?

Thank you.

I'm not a previous AT&amp;T customer, so I'm not sure about mMode, but here goes anyway:

1. Typically any kind of data connection that you buy to use via GPRS is completely independant from your "talking" minutes. That's why many plans are available for 5MB a month, unlimited, etc. Because they don't have any correlation to your monthly minutes.

2. If dialing *99# doesn't go through mMode (which I would bet a large sum of $$ that it does), you could conceivably connect via your ISP as you mentioned in question 3, but in that case it would be using your phone's minutes as if you were talking (since it's acting as a traditional modem)

3. I've never connected via ISP like this, so I've got no advice to add! If you are planning on using your ISP though, I'd cancel the $$/month you pay for the data connection... you're losing money there!

Hopefully this helps, and hopefully it's accurate! Someone else can freely correct me.

1. By dialing this way (*99#) am I going through mMode or using data minutes that I will be charged for?

You are connecting to the Internet using whatever Data Plan you signed up for. In your case it is the unlimited mMode.

As for the charge. I am not familiar with mMode unlimited. I know on T-Mobile's unlimited Internet Data Plan I do not get charged. But I know certain carriers like Verizon monitor their customers on the unlimited data plans to see if they are using laptops or Pocket PCs with the phone as the modem. They do not allow it. They detect it and bump the customer into a bigger more pricier data plan.

So I would read the fine print on the mMode contract. They may mention things like audio/video streaming, laptop data connection etc not allowed.

Or maybe another AT&amp;T customer can clarify things. If not call and find out.


2. Is there a way to set up the connection so I connect my laptop to the net via SMT5600 using mMode if the *99# does not go through mMode?

You are currently connecting thru mMode.


3. I tried to connect to my ISP (BellSouth) putting their phone number, my username and password, but I get the message: Connection Failed. Any thoughts on what am I doing wrong?

Again this is something that the carrier's can detect and restrict you.

But...Wish I had better suggestion. I would recommend that on the laptop, in the dial-up connection, click Properties->Security tab->Show Terminal Window. Enable this option and dial the ISP number. A window will popup upon successful connection with the ISP and you can usually make out from the screen whats happening. Or get some more error details.

If you are familiar with the 80s/90s dial up connection and hyperterminal. Then you know what I mean. ;-)

Well wouldn't you know. I was trying to connect my SP5M to my laptop via Bluetooth, and couldn't get it to work the first time, so I type "SP5M bluetooth modem" into Google, and Kris' article here is the #2 hit. Turns out the dialing string that was used by default was wrong - as soon as I changed it to *99# it worked perfectly. Woo hoo! Great job Kris. :-)

You feel on top of the world, when you do a Google search and find that your site/article is in the top five. :mrgreen:
