It would be interesting to know what prevalence of dual-sim phones are in those countries. Equally tourist levels as there appears to be no single definition of active phone numbers per country. Do they include roaming numbers, some may, some may not. But no single source for this data set and each number set has its own source for that data, which have no standard metric across all sources for how they are measured. But certainly a more insightful way of viewing this data than the totals alone.
