Not all systems in developing countries develop at the same speed. Some systems lag due to regulations, culture, etc. Other systems manage to leap-frog a generation.

I've been in Qatar for business. Coming from the US, it is shocking. Some systems have leapfrogged -- e.g., ease of banking, 2FA, mobile phone plans, messaging, ride-hailing apps, etc.

Other systems lag -- the most egregious example being the lack of a national address system. Correct -- i have no home address. Half the country does not -- people send GPS coordinates and WhatsApp location pindrops for ride-hailing and food delivery.
