Verizons Share Everything plans may be convenient for multi-phone households, but theyre not cheap — even the 500MB tier can be pricey for those who dont need much data. To that end, the carrier is introducing a $20, 250MB shared data plan on January 21st. The new offering shaves about $20 off the base rate, and lets a single smartphone owner pay as little as $60 per month for full service; a customer with a basic phone pays $50 per month.
