First, I'll say that i do this with my Treo650 using Cingular and I have an unlimited data plan, so it doesn't cost me any money besides the 19.99 i pay for the plan, I want to reiterate that if you DO NOT have a data plan and you use data, then you will be charged extremely high rates, with cingular its 3 cents per kilobyte. so approximately 30 dollars per megabyte, and if you know anything about computers, 1mb isn't much for surfing the net. It is possible to use what is called CSD, which allows you to use your minutes, but your provider must enable this service, in my area, cingular does not support csd, so i use gprs.
I will say this is not easy. It takes work and many failures to actually get it to work. First, terminology might help so that if what i say here doesn't help, you can find more info online, trust me, its there. GPRS is a data service for GSM telephones. GSM providers such as ATT, Cingular, T-mobile, blah, blah. This is also possible with Sprint phones, which can use data, but it isn't called gprs, i'm not sure what its called, i just know its possible. Then you have your CDMA or TDMA phones, which do not have a data plan, so you would have to see if your provider supported CSD which would allow you to make a dial up connection just like you would at your house.
What most of you are going to try to do is called BTDUN. Or bluetooth dial up networking. There are a few things you have to do before you can complete this. The hardest part is finding the user name and password. These are some, but remember these only work with phones with data plans, NOT with phones dialing up.
For Sprint:
Username: "your vision
[email protected]"
Password: "your vision password"
(If you don't know those contact sprint tech support and they will help)
Phone number: #777
For Verizon:
Username: "your phone
[email protected]"
Password: vzw
Phone Number: #777"
For Cingular:
Username:
[email protected]
Password: CINGULAR1
Phone Number: **99***1#
Once you have this, you set up on your mac which user name, pass, and phone number. Then you find the driver. For the motorola people, OSX has one built in, there are many drivers built in, if not just do a google search for your model name and "modem driver". you'll find it, trust me.
Now once you have the driver, and the numbers, pass, that you have a data plan, and your cell phone is paired with the computer, its time to try and connect. Just select the correct profile on the mac, and hit dial. make sure bluetooth is turned on on BOTH devices, and it will do the rest. if you've used the correct driver, and the correct user, pass, and number, you should be connected. if not, welp, you did something wrong, get a diff user name and password.
With the mac, there can be problems with modem scripts. For cingular you are to dial **99***1# but i have to dial wap.cingular if you come across the problem of the number being incorrect, you'll have to spend the google time to find what number you need to type.
Phew. i hope this helps, good luck.
