Activate your T-Mobile USA sim card here
Please note that this activation form is strictly for the use of customers of simcardguru.co.uk. If you purchased your sim card through a retailer in the United States you will need to activate your sim card at t-mobile.com or through the store you bought your sim card form.
Your sim card will be activated with your US mobile number sent to you by text message after you arrive in the United States.
Please note: it usually takes around six hours for your activation to complete so it is best not to leave this to the last minute prior to travelling to the USA.
