I transferred my personal cell phone (not the family’s, just mine) to Google Fi a few days ago. So far it seems to work well, although I’ve not had a chance to use it far and wide yet given the pandemic.
The only downside I’ve found thus far is that when dialing a local (607) number I have to use the 607 prefix or the call goes wonky–selecting its own area code to call. So I end up dialing 10 digits instead of 7 for local calls. But given 99% of the time I’m calling someone in my contacts list anyway, it doesn’t seem to be a big deal.
I’m estimating given my low usage of data the plan I’m on will cost me around $30/month for my phone.
I didn’t transfer the fam’s phones to Fi because they use iPhones and there’s some hangup with reworking the settings for texting to non-iPhone users. I’m an Android, everyone else is an iPhone. Supposedly a change to the iPhone’s settings is easy and quick, but every time Apple does a major upgrade you need to redo the settings to be sure you can text to non-iPhones. No thanks.
The thing I’m most excited about is that my particular phone model (a Motorola G7) can automatically change the network it uses for Fi–GSM or CDMA or secure Wifi hotspots. The Fi service uses Sprint, T-Mobile and U.S. Cellular networks for its signal. My phone can switch and use whichever signal is the strongest, automatically.
