Hi I am having trouble getting my mobile internet working I am using a Samsung GT-3350 its settings are similar to the Samsung GT-3550 in the help section so tried it and no luck, I also received a configuration message from 48 for mobile internet and one of the options in the message is to install it so when I clicked it it asked for a pin so I put in the pin on my simcard and no luck either any idea what this pin might be? I don't want to put it in wrong too many times and block it?
