Our take on the Mint Mobile 3 Month Unlimited Plan SIM Kit

A prepaid SIM kit that gives you three months of unlimited talk, text and data on T-Mobile's network, with 20GB of hotspot each month and free calling to Mexico, Canada and the UK. It is sold as a short-term plan, so you activate it and keep your existing number or take a new one. The catch is the data policy: speeds may slow after 50GB in a month when the network is busy. Against the big three carriers it trades extras like device financing and store support for a simple, no-contract prepaid setup, and reviewers generally rate it well for value and coverage while flagging slowdowns and support as weak spots.
