Univision Mobile Sim Card includes a 2FF & 3FF Regular and Micro SIM that lets you connect any single unlocked GSM-compatible smartphone to Ting’s cellular service. Ting runs on the T-Mobile network, so you will enjoy nationwide coverage wherever T-Mobile is available. After setting up an account with Ting, you can use your phone as much, or as little, as you want. With Ting, you only pay for what you use in a given month. There are no plans, no contracts, and no cancellation fees.
