Just to clarify, Republic actually changed to the current plan model a year and a half ago when they introduced the Clear Choice plan for the unlocked phones. The major change now with My Choice is to make data cheaper than it was with that plan ($5/GB instead of $7.50/GB).
It is, of course, up to every customer to decide if that is still more than they wish to pay. (And, it’s always a good idea to check periodically to see what alternatives might be a better match as both Republic and other carriers continue to evolve. None of us knows what the landscape might look like a year from now!)
