I've been keeping mobile data turned off unless I explicitly need to use it. I turned it on last night to google something quickly, and it managed to use 60mb.
Can't wait to go back to mintsim after I satisfy the 4 month requirement from their cyber Monday deal.
Like one of the other posters said, I don't stream on phone, and use the wifi at home and at work. I'd love to see the breakdown of data usage (reported by the phones) for heavy users. I wonder if it's like 4GB netflix, 200MB chrome, 100MB Tinder, 20MB Uber, 5MB email.
I have a 5GB plan and rarely use half of it in a month, even though I spend plenty of time using various mobile apps.
It's probably pretty simple: I don't do any streaming: music, podcasts, internet radio, etc.
If you really "need" to stream YouTube videos away from a WiFi hotspot, then you should just pay $150/month and stop complaining.
googling something does not take 60mb. as soon as you turned on data, a whole bunch of google's android crap and other apps started phoning home and sending the data they've been collecting on your phone at the expense of your battery life.
My single gripe about Project/Google Fi is that sometimes I'm forced to use a 3rd party app (FiSwitch) for when it doesn't automatically switch to the best carrier for that area, but even with that the cheaper price is enough for me to stay. I still hope they improve the carrier detection issue though.
Compare that with T-Mobile, who offers $70 a month (including taxes/fees) with throttling at 50GB and 20GB of hotspot data for $15/mo more, or even AT&T or Verizon, and it's more expensive for less service.
Most of the time my phone is on wifi and only using data during travel why pay for anything Im not expecting to use. If I'm off wifi enough where I'm doing a lot of data I'm not using Fi.
Look at it as https://en.wikipedia.org/wiki/Price_discrimination. A carrier can charge a lot to their locked-in customers, and sell spare capacity at lower markups to people who have competing alternatives, as long as all not everyone abandons them and moves to Fi.
* they're also probably one of the only honest carriers in terms of taxes/fees. My previous carrier had a much higher tax % which I thought was normal, but now I realize it was just a markup disguised as a tax, so they could continue to offer their "$40/month for everything" price point while actually charging $50/month.
