In Portugal Wiko is also a top selling brand, I doubt if the person was (really?) in France, and never seen a Wiko...even in the underground (Metro) is full of their advertisements! Tourists these days are so "low-cost" and the majority doesn't even speak a proper English...what about French!
when i was in france, most people there were using samsung/iphone/kindle devices.
so, i doubt they even know about wiko.
