I add the minimum. In many countries (Switzerland, UK, New Zealand) the minutes don't expire, and the number is mine to keep unless it doesn't connect to a network at all for a year or more. Yes, I pay per minute for outgoing calls, or MB of usage - and those costs are high. That's why I try to use WiFi whenever possible, and use offline maps, offline Wikipedia, etc. https://www.cable.co.uk/mobiles/worldwide-data-pricing/ https://www.cable.co.uk/mobiles/worldwide-data-pricing/
