Indonesia has said it is considering following the lead of Saudi Arabia and the United Arab Emirates in banning BlackBerry services, adding to pressure on device maker Research in Motion Ltd to give governments greater access to data.

Gatot Dewabroto, spokesman for the Ministry of Communication and Information, wants RIM to set up a server locally so encrypted information sent by the phones will not have to be routed through the Canadian company's overseas computers.

"We don't know whether data being sent through BlackBerrys can be intercepted or read by third parties outside the country," he said yesterday, expressing concern that information could be used by criminals or spies.

The announcement came hours after Saudi Arabia said its telecom regulator had ordered mobile operators across the kingdom to halt BlackBerry services as of Friday.

The United Arab Emirates, too, plans to shut down e-mail, messaging and Web browsing on BlackBerrys starting in October.

India is in talks with RIM over how information is managed on the devices.

Analysts say RIM's expansion into fast-growing emerging markets is threatening to set off a wave of regulatory challenges, as the device maker's commitment to keep corporate e-mails secure rubs up against the desires of local law enforcement.

RIM has said discussions with the more than 175 countries where it operates are private. It does offer help to governments, but says its technology does not allow it, or any third party, to read encrypted e-mails sent by corporate BlackBerry users. (The consumer version has a lower level of security.)

The e-mails are, however, unencrypted on the servers of corporate clients, and can be obtained from the companies.

Satchit Gayakwad, an RIM spokesman in India, denied there were plans to give the government greater control over surveillance of its corporate clients.

"We won't compromise on the security architecture of our corporate e-mails," he said. "We respect the requirements of regulatory bodies in terms of security, but we also look at the customer's need for privacy."

Dewabroto said Indonesia, one of the largest providers of Blackberry services in Southeast Asia with more than 1 million users, is still just mulling a ban.

But it wouldn't be the first time it has taken on the device maker: Service was blocked in 2008 until RIM agreed to set up sales service centers for users inside the country.
