STi Mobile is no longer in service. Its operator filed for bankruptcy in 2012 and the service was gone by early 2013. Here is what that means for an STi Mobile number.

Account Number

There is no STi Mobile account number to retrieve. A Kentucky PSC letter records STi Prepaid LLC filing Chapter 11 on September 5 2012 in the Southern District of New York, with six affiliates petitioning at the same time. Customers reported support going dead in early 2013.

Transfer PIN

STi Mobile no longer issues transfer PINs. Neither of its domains returns a reachable page, and no successor carrier took over the base.

STi Mobile stopped operating in 2013. The only source naming a host network for it names the Sprint network, which was itself retired in 2022. We have not recorded a host network for this brand, because no reliable current source states one. We do not guess.

Your number and your rights

Number portability is a federal right, not a carrier policy. It applies only while a line is active — once service ends and the number is released, there is nothing left to transfer.

STi Mobile is gone, so there is no transfer to make. If you are choosing a carrier now, start from the network that covers your address rather than the brand on the bill.
