In a world where prepaid carriers and T-Mobile’s own uncarrier strategy continue to change up the way we look at smartphones and carrier plans, the big U.S. networks are doing more than ever to attempt to entice new customers or keep old ones from leaving. To that end Sprint announced a new leasing program for the Galaxy S5 a bit earlier today, and now AT&T and Verizon are both trying to lure folks with limited-time increased data offers.

First up, AT&T is boosting the data on its $40 and $70 Mobile Share Value plans for those that sign up between November 2nd and the 15th. The new changes see the former plan go from 2GB to 3GB, and the latter jumping from 4GB to 6GB. In addition to more data on the above mentioned plans, AT&T is also extending their “Double the Data” deal for two more weeks, giving you the chance to nab 30GB data for $130 a month. Of course that’s not including the $25 extra charge per shared line.

Not wishing to be outdone, Verizon is also following suit with a similar “limited time” move that kicks in tomorrow but has no set expiration date. The new offer gives folks the option of getting 10GB of data for $80 or 15GB for $100. Even better, the deal is for both new and existing customers. Furthermore, Verizon has a new limited time promo for new customers that gives them a $150 one-time credit simply for porting their phones from another carrier over to Big Red.

What do you think, anyone interested in either AT&T or Verizon’s offer?
