In Taiwan, unlimited 4g data plan is around 700 twd/mo (25~30 usd/mo depends on exchange rate). Double if 5g instead of 4g. Some people that don't play games even drop wired network because 300ms isn't a issue if you only watch YouTube. And from what I see. No body is using sms now. Everyone use message apps(line, fbmessanger, telegram, discord) and they also expect everyone have it even in elders.
If anything I hear about horror stories in Canada and I'm very glad I don't have to deal with their rates.
