I've been a google fi user for about a year and have noticed that the data speed after the max data limit is way too slow and nearly unusable. I have a flexible plan. Aaccording to google, I should have unlimited data to use after reaching $60, but in reality, the data is so slow, I cannot even use basic google maps. I think google is definitely playing with words. I feel like even the slow data should be at least 10 mbps. Come on google. You are a big company with lots of money. Don't skimp on little things like this.

My parents (ex-iPhone users, Verizon) recently bought Pixels and switched to my Fi plan. The only issue is that for some reason, since moving to Fi with Pixels, they're using a lot more data than they did on Verizon with their iPhones. Since we're on the flex plan this is a bit of a problem.

Does anyone have any guidance to help my technologically challenged parents avoid using too much data?

I was under the impression MVNOs can't offer unlimited data due to them paying per GB, which is why only main brands like Verizon/T-Mobile and subbrands like Visible/MetroPCS can offer truly unlimited data.

But seems US Mobile recently released an unlimited data plan on AT&T.

So will Google Fi ever release one? I know they recently raised the data buckets to 50GB/100GB from 35/50GB, which is better, but still not unlimited.
