Metro by T-Mobile offers great deals and a generally positive customer experience, according to the reviews. The salespeople can be slightly pushy, but they provide valuable assistance, such as helping customers add home Wi-Fi at a low additional cost. However, some customers have had issues with the company's communication and policies, particularly regarding the lifeline program. One reviewer, a disabled senior, was disappointed with the lack of information and the long wait time to get approved for the lifeline service, leaving them without a cellphone for an extended period. Despite these concerns, the overall sentiment is positive, with praise for exceptional customer service representatives who go above and beyond to assist customers.
