Hello all,

As far as I have known, most of cellular network operators build their cellular broadband data network GPRS/EDGE and 3G to support the down-link connection from mobile devices for web surfing, checking email, downloading the music, etc . However, there are still some operators such as AT&T in US which provides the up-link connection to mobile devices ( So we can use a laptop as a server for accessing through the cellular network)

I want to know exactly about other leading network operators (beside AT&T) in such countries as

USA (T-Mobile), Canada (Roger wireless, Bell mobility, Telus mobility),

United Kingdom (O2, Vodafone, T-mobile, Orange, 3), Germany (T-mobile, Vodafone, E-plus, O2), France (Orange, SFR, Bouygues Telecom),

Australia (Vodafone, Hutch 3G, Optus, Telstra),

China (China mobile, China Unicom, China Telecom),

Brazil (Vivo, Claro, TIM, Oi, NEXTEL)

and South Africa (Vodacom, MTN, Cell C)

whether or not they support that in-bound traffic?

What APN they use for ? What IP address is provided, Static or Dynamic? User name and password ? Charging rate? idle timer ? Connection timeout?

The problem is that those information I could not get from their customer service support, so I greatly appreciate if you guys could help me to figure it out.

Thanks for your great help,

Uyen
