Since then, it’s been pushing it pretty hard in stores, even going so far as to offer a $50 bill credit for those who signed up through a retail store. Now the Un-Carrier is widening the net a bit, offering the $50 promo through T-Life directly without requiring in-store sign-ups.Don’t want to miss the best from Android Authority?
