(Telecompaper) T-Mobile US is relaunching its Test Drive offer, allowing new customers to try out its network free for a longer 30 days free. Rather than using a second phone, they will receive a Coolpad Surf Device hotspot to test the network, including support for T-Mobile’s new 600 MHz frequencies. The trial is limited to 30 days or 30 GB, whichever comes first, with no charge for the customer.
