Any modern Android on Sprint can make calls over the LTE data just like WiFi calls. The iPhones can't do it because it's not real voice over LTE so Apple blocks it.Sprint works for me. 5G next year brehs
Me and my girl on the same plan. Got 2 iphone x,2 apple watches. Unlimited everything. Bill is under 200 a month. Can't beat that. Very rarely i have connection problems.
Not being able to talk and surf the net sucks but supposedly the new models will be able to(The note 8 can already do it on sprint) So i'll ride it out til next year and upgrade to a new model that can do it and have 5G.
