Given the shitty customer service you get from both MTC and you local authorized dealer here is a brief guide to help you set your GPRS connection.
Instruction applies for Sony-Ericsson W800i W810i K750i and probably others. also intended for MTC Kuwait postpaid customers.
Go to Main menu>Setting>Connectivity>Data comm.>Data accounts
Now create a new account select GPRS data and call it GPRS .
All you have to do is enter the Access Point Name apn01 and leave the usersname and password blank. leave everthing else AS IS.
NOTE: if you’re trying to connect from you laptop thru your mobile, make sure you mention the correct APN from the list. If you get a 734, 718 or 720 errors most likely you did not define the correct APN path for your dialup connection.
