The $10 a month charge for all smartphones is so Sprint doesn't cap data limits (like every other carrier does) and keep the speed of 3g and 4g superior. National reviews have shown that even with the new fee, Sprint plans are still fa superior to other data plans.....that have limits on data and charge for usage beyond the limit.They have a $2/month voicemail-to-text feature as well (one month free trial). No thanks. Sprint is starting to nickel-and-dime subscribers these days. First the $10 fee for all smartphones (not just 4G), then the premier split into 2 tiers, and now stuff like this.
