AT&T has joined the prepaid mobile broadband fray with the launch of a pay-as-you-go data service that includes daily, weekly and monthly pricing.

AT&T’s new plans are considerably cheaper than those offered by rival operator Verizon Wireless, whose prepaid mobile broadband plan costs $80 for 5GB over the span of 30 days.

AT&T’s DataConnect Pass starts with a $15 day pass that gives users 100MB of data. The company is also offering a $30 week pass that provides 300MB of data and a $50 month pass with a 1GB limit.

The carrier also announced two new netbooks and a new laptop, the Acer Aspire One 532h, Dell Inspiron Mini 10D and the Acer Aspire AS1830, respectively.

The Acer Aspire AS1830 costs $239.99 with two-year contract and features an Intel Dual Core i3 processor with 2GB RAM, 250 GB Storage, 2GB of memory, 11.6 inch display, up to 6 hours of battery life, a 1.3-megapixel web camera; it runs on Windows 7 Home Premium. The laptop costs $649.99 if purchased without a contract.

The Acer One 532h and the Dell Mini 10D each cost just $39.99 with a two-year contract and $449.99 when purchased without a contract.
