Do you know someone from a foreign country coming to the U.S. to visit? You could be doing them a big favor by telling them about T-Mobile's new Tourist Plan which debuts on June 12th. The Tourist Plan is a short-term service made specifically for those visiting the U.S. for a brief time. If you have friends or family coming to the states to visit, and they were wondering about the high price of roaming, or unsure what they were going to do with their smartphone, this could be the answer.The Tourist Plan costs $30 for three weeks of service. Users receive 1000 minutes of domestic phone calls, unlimited data (with 2GB of high-speed 4G LTE service) and unlimited domestic and international texting to more than 140 locations. And T-Mobile will even pay for the tourist's SIM card and activation.Once arriving in the U.S., the tourist needs to bring his unlocked smartphone to the nearest T-Mobile location. Once inside the store, he/she simply tells the rep, "I want to sign up for the Tourist Plan." The tourist then forks over the $30, gets the phone activated, and is given a U.S. phone number to use for the duration of the plan.The plan is good for three weeks only, and is not renewable. Also, un-carrier features like Binge On are not included.source: T-Mobile
