According to Wikipedia:
“Global System for Mobile communications (GSM) is the most popular standard for mobile phones in the world. Its promoter, the GSM Association, estimates that 82% of the global mobile market uses the standard.
GSM is used by over 3 billion people across more than 212 countries and territories.
Its ubiquity makes international roaming very common between mobile phone operators, enabling subscribers to use their phones in many parts of the world.”
