For those on prepaid: would you think it'd be nice to have an auto-refill feature for boosters? Currently, you can renew your baseplan automatically by registering a credit card in Self-Serve. I suggest that besides each booster you buy, there should be a checkbox to allow auto-renewal of said booster using the same credit card you have on file in Self-Serve. This way you could have uninterrupted service without having to "remember" to top up + re-buy a booster. Basically, simply allow an empty booster to refill itself just like the baseplan with a registered CC. Maybe it's just me, but I think it'd be convenient! Whaddya think?
