Does anyone have one of the round watches using T-Mobile in the US?

Does anyone have one of the round watches using T-Mobile in the US? I sent back a Finow X5 because it would not work. T-Mobile techs on their help line said it was incompatible with their service. Mr. Ticks of Smartwatch Ticks on YouTube says they work on AT&T which he has but unfortunately I do not.

I just recently started using a data only sim from Project Fi on my No. 1 D5. It uses T-Mobile (and a couple other carriers). There seems to be an issue with Google sync when on 3G, though.

Apparently using this app you can edit the APN file directly.
There is a post about it here on the forum

Thanks, but I think its working. I can browse the web. The Google apps just seem to take a while to update and report no connection sometimes. I’ll keep looking into it.

I did a speedtest and I’m only getting ~128 kbps download and ~212 kbps upload. That seems like a 2G speed, even though the 3G symbol is displayed for the connection. Even having Wifi enabled (but not connected to anything) doesn’t help.
