Open International pass – The legal stuff you need to know

New or existing Flext customer? You can add the Max £5.00 a month or the Light £2.50 a month option to your account at any time by contacting us on 150 from your T-Mobile phone or by visiting a T-Mobile store. We're afraid that this plan isn't for business registered customers and you may have to pay a deposit. We'll let you know when the option has been added to your account, which should be immediately.

If you choose Max you'll then get 15p per minute calls to mobiles and 4p per minute calls to landlines in our pick of countries (except to the USA and Canada, when you'll be charged just 4p per minute for calls to mobiles and landlines).

If you choose Light you'll then get 20p per minute calls to mobiles and landlines in those countries.

Calls are all from the UK (England, Wales, Scotland and N. Ireland) to: Australia, Austria, Bangladesh, Bulgaria, Canada China, Croatia, Czech Rep, Estonia, France, Germany, Hong Kong, Hungary, India, Indonesia, Italy, Israel, Jamaica, Japan, Korea, Latvia, Lithuania, Malaysia, Netherlands, New Zealand, Pakistan, Poland, Portugal, Romania, Russia, Singapore, Slovak Rep, Slovenia, South Africa, Spain, Sri Lanka, Taiwan, Thailand, Trinidad & Tobago and USA, Ireland, Ghana and Turkey.

Calls to premium rate numbers and other non-geographic numbers (which can vary over time) aren't included. If you're a Max customer, we have a minimum call charge of 15p (to mobiles) and 4p (to landlines and for all calls to the USA and Canada). If you're a Light customer, we have a minimum call charge of 20p. Your option will stay on your account until you ask us to take it off, which we try to do before it goes onto your next bill.
