If the non-supported phones are stuck on T-Mobile's network and don't support the seamless WiFi/Cell switching, what advantage is there to picking Fi over regular T-Mobile service? Price-wise Fi only wins if you use very little data.

It's nice to have SMS and Call integration with Hangouts, so I can just as easily text message or make and receive calls on the PC.

As far as I know you can still do this with Google Voice + any cell carrier for free though.

Fi also wins over T-Mobile for international data, where they give you 4G instead of 3G.

(Unless things have changed—when I had T-Mobile, you had to pay extra for international 4G)

It is still the case:

> When you travel abroad in 210+ countries and destinations you will have unlimited data at up to 128kbps [...]. If you frequently travel internationally and require a higher speed you can add T-Mobile One Plus™ and get up to 256kbps speeds abroad for $15/mo.

For full disclosure their "One Plus" offering does include other things:

- HD streaming.

- 20GB of 4G LTE mobile hotspot data.

- Unlimited in-flight Wi-Fi.

- Voicemail to Text.

So you can debate if Fi (international 4G) or T-Mobile w/One Plus (in-flight Wi-Fi) is superior for international travel.

This is correct. Out of curiosity, have you required 4G while roaming?

For maps, music and Uber 3G worked just fine for me in the UK and India.

I'm in Europe every year, and the T-Mobile 3G speeds are unbearably slow. I switch out my SIM for a (much cheaper!) EU SIM card after arriving.

Note that with T-Mobile's roaming, you're still on the 4G/LTE network. It's just that they throttle you to 3G speeds.

At least it's better than it was 2-3 years ago, when they actually limited your phone to EDGE (!).
