While a common supposition prevails that a WiFi connection is better than the data network connection but in these 33 countries, it is the exact opposite. OpenSignal performed a research and they determined that mobile internet speeds were far better than WiFi in 33 countries around the world.
Their studies prove that mobile networks are no longer inferior to WiFi connections and they are now faster and more reliable due to advanced and sophisticated bands being used by telecom operators.
As you can see, there is a huge 13Mbps speed difference between mobile internet and WiFi connections in Australia.
Whereas in Pakistan, there is a 2Mbps difference in speeds which is not a lot but just enough to give mobile internet connections the trump card.
Even in countries like Qatar, UAE, and France, there is a noticeable speed difference between WiFi and data networks. A better comparison, however, would have been in regards to the reliability of speeds and the cost per Mbps as well as the amount of data being provided.
