The FCC is pushing for a rule that would require carriers to unlock phones within 60 days of activation, a proposal met with strong opposition from T-Mobile and AT&T. Both argue that quicker unlocking could raise device prices and limit subsidies for low-income consumers, with T-Mobile warning that it could slash prepaid device subsidies by up to 70%. Meanwhile, consumer advocates support the proposal for enhancing competition and consumer choice. The debate highlights a clash between consumer rights and carrier business models in the telecommunications sector.
