Samsung Instinct Cell Phone: How to use it as a modem, connected to my laptop via USB ?

> its only disabled  for the Simply Everything Plans

I don't know what the 'simply everything' plan is... when I got mine they said it required a data plan (i.e. you could not activate it without paying $20 extra per month for internet access).

With a little hunting around I was able to turn on the modem in mine and connect to the internet with it. Be aware Sprint has a 5GB/month limit, and you exceed that with your Instinct as a modem you may be liable for extra charges or subject to cancellation. And I'm betting they won't refund for the phone if that happens.

I took screenshots and pictures of the phone while I was doing it, then decided just the written steps should do.
You need the 6-digit Master Lock Code (MSL) for your phone before you start. I've read where entering the wrong MSL could brick your phone, so I suggest you don't start this procedure without it written down so you can refer to it as needed.

 1.) From the dialpad enter ##debugmenu#  (that's ##332846368# since you can't enter letters).
 2.) Enter Current Code dialog appears - this is where you enter the master lock code, then click Done.
 3.) On the Debug Menu select Toggle NAI down at the bottom.
 4.) Select ''Off Modem NAI'' which should return you to the Debug Menu screen, then click Done.
 5.) Back on the dialpad, enter ##USB#  (##872#), a dialog should appear that says 'USB as MDM'.
 6.) Plug in the Instinct's USB cable to both the phone and the computer.
 7.) Open up Nework Connections, click ''Create a new connection'' at the top of the left pane's window, then click Next.
 8.) Select ''Connect to the Internet'', click Next.
 9.) Select ''Set up my connection manually'', click Next.
10.) Select ''Connect using a dial-up modem'', click Next.
11.) Select the proper adapter if there are multiples shown, e.g. SAMSUNG Mobile Modem (COM#)
12.) For the number to dial use #777 (pound sign, seven, seven, seven).
       Username and password blank; check 'Save this username ...' and choose if you want just your logon name to be able to use it, or everyone.
13.) In the Properties, Options tab, UNcheck 'Prompt for name and password' and 'Prompt for phone number'.
14.) On the Advanced tab check the appropriate box[es] if you want to share the connection [and allow others to initiate/end the session].
15.) Back on the General tab, in the Configure button, set the 'bps' to 921600 if it isn't already, then check the 3 'Enable' boxes too. OK, OK.

Your phone should now appear in Network Connections as a Dial-Up connection. Right-click it and choose Connect. See if you can get to your home page. If so, you can now use a full size screen to surf instead of trying to display pages on the 1.5'' x 3.5'' LCD screen.
To end the data call, either right-click it in Network Connections and choose Disconnect, or slide the 'End' bar to the right just like hanging up to end a voice call. You cannot use its voice and data functions at the same time, of course.

IMPORTANT - enter ##USB# again to toggle the USB port back to MSC functions instead of MDM when you're done. The Media Manager can do file functions with it when the USB is in MDM mode, but windows can't... if you don't switch it back to MSC mode, the SD card won't appear as a drive letter in windows when you plug in the USB cable.

Without the Off Modem NAI setting in the Debug Menu, just toggling USB to MDM will result in error 67 (bad credentials) when you connect. So you cannot do this without knowing your master lock code.
