Is it the color of the bubbles? That seems to be a US only issue. Most of the other countries barely use SMS and use WhatsApp/Telegram/whatever instead.
Last time I checked my plan has 100 free SMS per month (Italy.) Imagine what people are using on their phone (Apple or Android) here: iMessage/SMS or WhatsApp?
Not sure about Italy but here everyone and their dog have unlimited SMS unlimited data and unlimited local calls. With unlimited data there absolutely no reason to use SMS anymore, especially when everyone has WhatsApp (or similar) installed on their phones.
