Tourists visiting the U.S. can visit a T-Mobile store with an unlocked GSM smartphone, sign up and pay for the plan, and receive a free SIM card to access the carrier's network. The one-time, one-line plan lasts 3 weeks and cannot be renewed after automatically expiring at 11:59 p.m. on the 21st day of service.
International phone numbers cannot be ported to the U.S., so T-Mobile will assign customers a new U.S. number when they sign up for the Tourist Plan. International calling from the U.S. to other countries is not included in the plan and cannot be added as an additional feature, but customers can use Wi-Fi-based calling services.
The Tourist Plan includes 200MB of U.S. data roaming, but other T-Mobile perks such as Mobile Without Borders, Binge On, and Music Freedom are not included. The plan permits tethering, with Mobile Hotspot using data from the 2GB allotment of 4G LTE data, followed by slower speeds afterwards.
The new plan is available June 12. Postpaid and T-Mobile@Work customers are ineligible.
