You know the drill by now: a major carrier such as AT&T introduces a new feature, years later T-Mobile makes a feeble attempt at copying it. While T-Mobile has no apparent plans to give its post-paid customers any love, the company has just added 7PM nights and weekends and free mobile-to-mobile calling to its Pay By The Day prepaid plans. Yeah, similar features have been available for as long a we can remember on AT&T and Sprint, with the latter now offering 6PM nights, but who’s counting? Pre-paid has significant drawbacks, but these new features coupled with the lack of contract might be enough to bring some new folks into the fold. Now how about some post-paid love, huh?
