How can I make international calls on my T-mobile phone?

Episode 1051 (1:48:50)

Juan from Los Angeles, Ca
T-Mobile

Juan got the T-Mobile 100 minute talk plan with unlimited text and data for $30 a month. Leo says that's a great deal. Juan isn't sure he can make international calls though. Leo says that they charge $10 a month for an international dialing plan with reduced per minute rate. Doing the math, it's probably just cheaper for Juan to pay the full rate. Leo advises not calling, but going into the T-Mobile store to talk to a salesperson. They'll give him the information he needs.
