Online visits and search referral activity to six leading prepaid wireless sites increased 37 percent over the previous year, according to a new report from comScore.

Growth in prepaid wireless was driven primarily by MyCricket (up 107%) and BoostMobile (up 105%), both of which more than doubled in visitation over the prior year. MetroPCS and Net10 also saw solid gains, growing 63 percent and 37 percent, respectively.
