Claro runs a separate prepaid network in each of the 15 countries it operates in, and Brazil is the one most people search for here. doctorSIM tops up a Claro number in any of them, without opening a Claro account. Whether it's your own number or a relative's, all you need is the phone and the country it's registered in.

Picking the right country
A Claro line only works with the country page it was activated in, since each network bills separately. If you're topping up for someone else, ask which country the SIM is from rather than guessing from a dialling code.
