What are your data needs ? And where do you need it?
I use 3 different providers to compensate for "dark " ares where 1 provider might not work.
I use my S7 Verizon as a hotspot for the majority of my work ( old unlimited dataplan ) ($130) then my wife has a 6 GB ATT hotspot on her Iphone 6 ( with 6 GB carry over data and network management after max data is allowed ).( $90) And we also have a T-mobile hotspot with 6G high speed and BINGO ON with 20 GB stash data ( $30)
Since ATT also returned their unlimited tablet plans we signed my wife's Ipad pro up for $30 ( network managed after 20 GB )
