    I have been trying to use my sim card with my portable modem to connect to the internet. I have in the past been able to do so in the past. The modem does connect to a laptop but is unable to access the internet. When started my browser comes up but a T-mobile website come up asking for a password. I have some money on this account that will expire shortly. How do I gain access to the internet? Is there something else to configure?
