Cubic Telecom is partnering with Ryanair to cut mobile phone roaming costs for travellers.

By purchasing a MAXroam SIM card and using it in an unlocked mobile phone, the user can save 60-80% on roaming charges in over 180 countries, but to make life easier it will offer a single fixed roaming rate across 43 European countries.

Ryanair passengers can buy a 'roaming bundle' which will include a phone, SIM card, and a €10 credit from Ryanair.com.
