> Here in France, SMS / MMS are still the most widely used What, which part? Over here SMS is used only as a last resort: interoperability when people aren't using the same set of messaging apps, or no data due to bad network conditions. Everyone is using Messenger (when mutually added), WhatsApp, Telegram, or iMessage, the latter three automatically populating when phone numbers are added to contact lists, which people happily upload.
