T-Mobile will follow suit with Verizon Wireless and AT&T an offer prepaid wireless data packages to its customers. Surprisingly, the packages fall in line with Verizon and AT&T, almost. Normally, you would expect the likes of T-Mobile and Sprint to be slightly, and often times substantially, less than the two behemoths. Nonetheless, the details of the prepaid plans are as follows: monthly 1 GB plan for $50, 300 MB one month plan for $30, and a 100 MB one week plan for $10. As you can tell, these plans will be sold in weekly and monthly increments (7 days and 30 days). So T-Mobile customers, is this good enough to make you leave the contract world?
