Congestion is the main problem in the Philippines, with millions of internet users but only few towers are created, so it's expected that the connection will slowed down especially during peak hours, best way to avoid that is to get a wire ISP, a little expensive but at least you don't worry anymore.
It's not with the congestion but a poor upgrade of towers and system networks here. Some towers are also being shared by other networks. Other countries don't have that great number of towers but their network system is good.
A few towers but built in a powerful network system can accommodate millions of internet users with a fast internet speed.
There are also no peak hours now and heavy usage is now seen 24/7. If PH ISPs can work on upgrading their cell sites, signals will be improved.
It's true to make internet connection smooth and fast, don't need too many towers, but what must be improved is the network system. I am not
a citizen of the Philippines, so I don't know the quality of the network system there. But if the signal you get is weak and often slows down
the internet connection speed, it means that there is indeed a problem with the quality of the network system and it really needs to be upgraded.
In my country I have the same problem, the network system quality is poor and the connection will suddenly slow down for several hours.
And this is quite annoying when we play gambling or online games if the internet connection is slow, indeed the only way to use an ISP that
already supports fiber optic cable. Because usually waiting for ISP to upgrade the network system will take a long time.
