5G networks are set to transform the mobile data experience. However, very robust 4G infrastructure means that people in some countries already have access to ultra-fast connectivity. Etisalat in the UAE tops the list, offering speeds of nearly 100 Mbps on average, 3 times higher than the US average of 33 Mbps.

Hmmm, that average is yet lower than I expected, IIRC Korean 4G regularly reaches >200Mbps, but perhaps the national average is half that. Either case, 5G is basically a joke.
Depends how far the antenna is. Definitely not made for online games and 100 GB file download and upload. I think 12 euros is too expensive.
