T-Mobile is again offering a FREE 30-Day Trial on their service for a limited time. There is no obligation to sign up for service and no credit card is required to try their service. To participate, you sign up and they will send you a pocket-sized hotspot to connect to your current phone to experience a T-Mobile’s network, including their 600 MHz Extended Range LTE coverage. You get 30-days or 30GB of data, whichever comes first. When you are done, you can return the device to any T-Mobile store or pass it on to a friend. It’s not available to current T-Mobile customers. T-Mobile Test Drive participants are limited to one device per household, or if you are representing a business, one device per shipping address.
