Twosim is a unique telephony system that is linked to two phone numbers ; a UK local mobile number AND a second international number - based on the country of your choice – so you can always be reached in the cheapest possible way, wherever you are in the world!

The  twosim sim card and mobile network works on a “pay-as-you-go” basis and you can ‘top-up’ your credit either directly from your mobile phone, or by logging onto the twosim website.  Don’t forget you can always use your gocard to buy credit!
