what mobile network uses the coolpad?
One of the company's specialties is combining network modes, and with its new Coolpad 8920, it's one of the first phone makers to build devices with TD-LTE and FD-LTE, needed for Sprint's new tri-band LTE solution. Coolpad's single U.S. customer so far, MetroPCS, has also just pivoted. Since it was bought by T-Mobile, the carrier has tossed out its CDMA phone roadmap and is auditioning new GSM/LTE devices to run on T-Mobile's HSPA+ and LTE networks under the MetroPCS brand.
