I briefly mentioned this in another thread, but thought maybe it might be of interest to a wider audience.
First, I am not affiliated with Google in any way, shape, or form. I don't even like google, but in some cases, one votes with one's wallet.
I used to maintain a "Family Plan" with Verizon for the Admiral's phone, and her brother's phone, who lives with us. The cost of the plan averaged about $180/mo. This was due mostly to the cost of the plan, meaning they are not heavy data users, and spend most of their time connected to the home wifi anyway.
About 6mos ago, I switched both of them over to Google Fi, which is Google's mobile phone service. It's actually a contractual "partnership" that Google has executed between Sprint, T-Mobile, and various WiFi providers. This means that a phone can be connected/serviced by any of those mechanisms. In spite of my skepticism, this truely does live up to their claim of working "seamlessly". My wife can start a call in our home, which is automatically placed over wifi, walk out to the car, drive downtown, and the phone will switch (if it needs to) between wifi, Sprint, and T-mobile, all during the call, with zero interruption. Pretty slick.
Pros of the plan are:
No contract...$20 for the "line", and you pay for actual data usage at the rate of $10/Gb. So if you use 2.1Gb of data, your bill would be $20 + $21, or $41 for the month. If during the next month you use .7Gb of data, your bill would be $27.
You MUST purchase a Google phone, so no BYOD, unless you already own a Nexus or other qualifying phone. You can purchase a certified refurbished Nexus 6 from amazon here:
The two phones now run between $45-$50/mo, TOTAL...so saving about $140/mo over previous Verizon plan.
They recently introduced "family plan", which allows you to have more than one line/account. Extra lines are $15/mo, instead of the $20/mo to have a separate account.
The Admiral has been exceptionally pleases with the service and performance of both the phone and the plan, which is no mean feat
My phone (Galaxy Note 4) is on my company's plan, so doesn't participate
