Disruptions to BlackBerry services spread to Latin America on Tuesday, more than a day after users in Europe, the Middle East, Africa and India suffered extended outages.
Research In Motion said it was working on the problem but gave no details of the cause.
"Some users in Europe, the Middle East and Africa (EMEA), India, Brazil, Chile, and Argentina are experiencing messaging and browsing delays. We are working to restore normal service as quickly as possible," it said in a statement.
"We apologize for any inconvenience this has caused," said RIM, which earlier on Tuesday said it had resolved problems disrupting its services in EMEA.
Network operators and users in EMEA tweeted that email and BlackBerry Messenger services were not working from around 1100 GMT. Probels related to email and instant messenger services were also reported.
