Boost Mobile extends its double the data promotion10
The $40 plan that gives buyers unlimited talk, text and 500MB of data, becomes a $35 plan with unlimited talk, text and 1GB of data. With the deal, you can grab unlimited talk, text and 5GB of the sweet stuff for just $45. The last tier is priced at $55, and includes 10GB of data along with the unlimited talk and text.
As we said, the deal was originally due to expire at the end of October. Now that the promotion has been extended, there is speculation that it will expire on January 5th. This should give you plenty of time to take advantage of the higher data amounts, and the lower prices. Don't expect Boost to bail you out again if you forget all about the promotion.
