Brazil's telecom regulator, Anatel, has decided to penalise three of the country's leading mobile phone providers due to the 'poor service' given to customers.
From Monday, the companies Claro, Tim and Oi will have their sales suspended in some Brazilian states.
They will also have to present a new investment plan within 30 days for the ban to be lifted.
