It may or may not be a good deal.

It does say mix and match networks, so at least it is a little unique.

$30/30 days + $20/30 days each additional line; up to 5 total. $10 one-time setup fee for each additional line.

UT&T&D, 3 Or 5 GB/30days (5 GB/30 days If GSMA or CDMAS) LTE. The website says:
"5 GB LTE
3 GB LTE on CDMA & GSMT"
