Sprint is trying to get its subscribers to move from CDMA handsets to LTE models. The carrier has already sold 1 million 4G LTE smartphones. It's been a fascinating process though, as Sprint has tried to move its iDEN subscribers to CDMA (the iDEN network will close its doors next June). Meanwhile, once on the CDMA network, the mobile operator wants to move these subscribers to LTE which right now is the end of the line. By the end of this year, 150 million POPs will be covered by Sprint's 4G LTE signal, increasing to 250 million POPs by the end of next year.
Sprint might soon have an advantage with its new sugar daddy. Once regulators sign off on Softbank's acquisition of 70% of Sprint, the carrier will have some deep pockets it will have access to allowing Sprint to pay for the completion of its LTE network.
