Sim not used for 4 years... Will it still work.



    long story short...

    United Kingdom visitor. Bought T-mobile Sim in New York 5 years ago. Reason - to get 1 month plan so I could use mobile data (internet) for 5 days.

    Soon visiting Los Angeles (for 8 days)...

    Will the Sim still be 'valid'? If so, how can I get a 1 month plan back on it? Do I need to visit a Retail Outlet?


    Thanks for any help you can give.
