You do not have to pay any fees to register a cell phone signal booster. According to the Federal Communications Commission (FCC) and major cellular carriers, registration is required but is completely free of charge. This process typically involves providing basic information about the booster and your account, and it can usually be completed online within a few minutes[1][3][5][9].
While you are not required to obtain pre-approval before using a signal booster, registering it with your carrier helps ensure compliance with regulations and assists in managing potential interference issues on the network[1][4][7].
