Pixel 3 user here. I pay $30/month on average.

What on Earth are you torrenting on your phone? I've never used more than 5 GB data in a month. Just wait till you're back on wifi before watching YouTube...

I had a family plan through t-mobile and after years of getting more expensive per month (no enterprise discount, increasing number of taxes/fees, etc) I switched to google fi and halved my bill.

Some tips for those trying to minimize bandwidth: 1) tell google phones to backup pictures/videos on wifi 2) preload maps for any cities you visit more than monthly 3) get a podcast app (if you listen) that preloads them when on wifi 4) get youtube red ($10 a month) for no ads, downloadable youtube videos, and downloading your top 500 songs.

With the above, even when traveling quite a bit I average 1-2GB a month. I generally use nav every time I drive just to get the traffic info/warnings.

Good for you.

I'm on WiFi at home and at work, and I just checked my bill and I used 5.53GB last month, and my wife used 9.72GB. I don't consider either of us to be heavy mobile users, especially since we can't get cell service in our home.

For cost-sensitive people who are content with T-Mobile networks and open to MVNOs, I suggest looking at Mint Mobile. The best ongoing rates are had when you buy in bulk: $15/20/25 for 3/8/12 GB LTE per month, as a 12-month package. It also has unlimited voice/sms, and it throttles rather than charging extra when you exhaust your LTE quota.

Oh, and they also support T-Mobile's WiFi calling, so you can have phone service in your home without cell signal...

If you have a spare phone, I highly recommend a Mint trial. There is a 7-day starter pack, which gives you two SIMs and lets you test briefly with a temporary number and then reactivate on the second SIM if you wish to port in your existing number. But, I thought the $45 pack was so cheap that I used it for a longer 3-month trial, after which I was happy to keep it alive as my new main service.

You also have to think about whether you care to keep your old grandfathered plan, i.e. on a backup phone. I kept mine because I can keep it alive for $5/year if not using minutes. But, I imagine I may drop it some day if it cannot be relied on to actually place an emergency call...

It was more tempting when I traveled internationally more. But now I'm down to just a few trips a year, and I don't ever call home. So this GFi unlimited plan isn't cost-competitive with my AT&T plan when taxes are added.

Maybe next time. It seems to be a good fit for certain profiles, and people on HN who have that profile seem to really like it. But it doesn't seem ready for mass adoption yet. It's certainly not the "disruptor" we'd expect from SV.
