I bought my wife's phone bundled with Fi with interest free installments. However since I had to activate the phone itself using her email id the installments never happened they charged me the amount all together. I called support but they didn't help/ didn't know how to. I have never had to call them since then which helps.

I myself have a republic connection which IMHO opinion is very similar and has a very similar plan getting bandwidth from different carriers to operate. Republic is much better for some reason in terms of coverage and is cheaper as well.

Overall I am appalled by the cost of mobile data and internet in the USA compared to countries like India. Reliance JIO just changed the game in India with the unlimited data and every other provider was forced to up their game. Not seeing anything like that happening here.
