How to tether on your new Windows Phone 7 – Mac OSX Edition! (For Samsung phones only)

Click here for the WINDOWS Version of this guide.

If all this news about lack of tethering on your shiny new Windows Phone 7 made you sad – this post might make you really happy! Unfortunately, tethering is severely limited to only *one* Windows Phone 7 device right now – the Samsung Focus! So if you really wanted tethering, and somehow made the right choice and picked up a Samsung Focus – you’re in luck. Here is a step by step guide to set up tethering on Mac OSX.

Step 1: Enable Diagnostic Menu and Switch USB Mode

First step is to activate the diagnostic menu.

a) Open up the phone keypad, and enter: ##634#


b) Hit Call. This will bring up the Diagnostic Menu.

c) Enter: *#7284# to open up the USB Mode Menu:


d) In the “Micro USB Test” menu, select the 2nd option: Modem, Tethered Call


e) It will ask you to reboot your phone. Hit OK/Confirm.


Step 2: Set Up Connection

a) Connect your Samsung Focus to your Mac, then open Network Preferences. (Use Spotlight and type: “network preferences” if you can’t find it).

b) If all goes well, Network Preferences will notify you of a New Interface Detected, called: “SGH-i917”.

c) Select the new interface, SGH-i917 from the left menu, and enter the following information:

For AT&T, use the following settings:

Phone#: *99***1#
Password: CINGULAR1

For Rogers, use the following settings:

Phone#: *99***1#
User Name: wapuser1
Password: wap

d) Next, click Advanced, and under the “Modem” tab, choose the following options:

Vendor: Samsung
Model: GPRS (GSM/3G)
For Rogers users:
For AT&T users: wap.cingular
CID: 1

e) Click OK, and back on the network screen, Click APPLY on the bottom right. Now you can click Connect and you should be able to start browsing!! Here’s my speedtest:

Closing Notes:

  1. Unfortunately, if you’re in tethering mode – your phone *will not* be recognized in Zune. You need to switch back to Zune Sync mode. The good news, is that once you have enabled the Diagnostic menu, it is now treated like an “app.” So if you go to the apps screen, there should be an app called “Diagnosis” like below. Just enter *#7284# and switch back to Zune Sync mode.
  2. Tethering ALSO works on a Windows PC. You can find the tutorial here.
  3. I will also put up a quick video tutorial soon as well.
