Venezuela's two main cellphone service providers are suspending long distance calling as the South American country struggles to pay its bills.

Movistar and Spain-based Telefonica both announced on Friday that they would be cutting international service because of issues related to Venezuela's byzantine currency controls.

The companies had already dramatically reduced the list of countries Venezuelans could call.

Movistar says the change will be temporary, but doesn't say when long distance calling will resume.

Currency rationing is increasingly cutting Venezuela's global trade. Many airline companies have abandoned the country, and mail delivery is also limited.

The government requires companies to get approval for converting local bolivars into dollars and is reluctant to part with foreign currency.
