I am using a blackberry phone and subscribed to BIS. I am trying to connect to the internet on the laptop via the desktop manager installed of BB on my laptop. I select the IP Modem option from the desktop manager and leave the username and password blank but put access point as internet or internet.tz.celtel.com but doesnt connect. i even tried putting internet.tz.zain.com and still didnt work... any idea or suggestion? thanks!
