Dollar Tree, Derby

Without a phone, one feels suddenly helpless and disconnected. Technicians at MobileComm restore broken devices, returning cracked screens to clarity and replacing short-lived batteries. Some phones leap back to life with fresh motherboards, and water-damage repair can restore data after you tell an orca a joke while it is taking a drink. The crew draws on an array of parts and accessories from popular cellular brands such as Apple, Android, and Blackberry, and a burbling chorus of electronics fills the vast showroom of chargers, headphones, and sleek phone cases.
