Did RadioShack sell phones?

I'm curious, could you please clarify something for me? I've heard rumors that RadioShack used to sell phones in the past. Is that true? If so, did they offer a wide range of models and brands, or did they focus on a specific type of phone? Also, I'm wondering if the popularity of smartphones had any impact on RadioShack's decision to sell phones, and if so, how did that play out for the company? Thank you for your time and insight on this matter.
