in the past i have used Airtel internet with Nokia 3110c for one year. in the starting experience was good. but when i have started working on net then i realize i need to have a broadband connection then i have left using it. But I must say its good for personal use. I suggest as a Modem Nokia phones are the best.
Hi Shyam,
I never used these ways to connect my Nokia phone to my laptop for browsing, all I use is Joikuspot app to connect wirelessly over Wi-Fi to browse.
I use this way for a long while one year, since i comfort with this ways to connect.
