The $10 unlimited t&t FU plan would be nice on the device, too. And at about $18 it's a great deal. Did yours come unlocked, or does it have to be unlocked in order to use it as you have done.
I had a similar idea with Beast Mobile $4/month plan and Sprint Phone Connect device, which can be had on ebay for ~$20-50 (depending on version). A few ebay listings showed MEID which I checked and apparently eligible for activation on Beast. Downside is relying solely on Sprint CDMA.
I have my dad on the Sprint Phone Connect device/ Tello, but I can tell you that the voice quality seems much better on the LG-AF300 device with AT&T service with the added benefit that you are getting 1000minute free with the FreeUp plan which is more than enough for me. However, I would not chance switching my dad to this plan as he uses it for his landline and needs it and Tello is very reliable and has great customer service.

There's no voice quality benefit to VoLTE compared to 3G cellular voice?
I also mentioned VoLTE support for wideband audio codec. Whether this will always result in improved call quality depends on a number of factors. Certainly, if the call is between parties/devices and service provider(s) all supporting wideband, with appropriate intercarrier peering arrangements, if applicable, then yes absolutely the call quality is much better. Note: Wideband codecs (in this context, AMR-WB) can be configured at different bitrates.
