Wireline telecom Frontier Communications Corporation (NASDAQ: FTR) is struggling as customers continue to switch to alternative communication options like cellphones. That’s already led to a dividend cut this year — so if you’re looking at the company’s huge yield, stop. Instead, consider the impressive yields offered by limited partnerships Alliance Resource Partners, L.P. (NASDAQ: ARLP) and Buckeye Partners, L.P. (NYSE: BPL), both of which just raised their distributions.
