The BlackBerry is still the world's most popular business mobile device, despite the general popularity of the Apple iPhone and growing popularity of Google Android devices.
But its future in many Islamic countries is under threat following the Saudi action.
A statement from the kingdom's Communications and Information Technology Commission said three servers were being tested, one for each of the three mobile operators.
Feedback was being awaited from the telecommunications firms.
The dispute started more than a week ago with Saudi authorities announcing they wanted to ban messaging services on devices, while neighbouring United Arab Emirates is planning an even more sweeping crackdown on data services starting in October.
A deal that allowed Saudi officials to access user data in the conservative Islamic country could set a precedent on how technology companies and governments interact around the world.
Several countries have said they saw BlackBerry devices as a security threat because encrypted information sent on them was difficult, if not impossible, for local governments to monitor when it did not pass through domestic servers.
The UAE said it planned to block BlackBerry email, web browsing and messaging services starting in October.
India, Indonesia and Lebanon have also raised concerns about the devices.
Critics warned that countries which maintained tight controls on the media were also motivated by a desire to monitor users' speech and political activity.
Bahrain's Sheik Khaled bin Ahmed Al Khalifa said the hand-held devices raised legitimate concerns but that his nation had decided that banning some of the phone's features was not a way of dealing with the issue.
"We are not saying there is no security concern.
"There are many other ways for the criminals or terrorists to communicate so we decided we might as well live with it."
Local media in Bahrain had reported that authorities were cracking down on the spread of some types of news and information provided by BlackBerry devices.
Sheik Khaled acknowledged some concerns had been raised but said sharing information using the devices remained legal.
Authorities were aiming instead to warn users against spreading slanderous and libellous information.
According to technology monitoring firm Gartner's figures, RIM sold 145,000 devices in Africa and the Middle East in the first quarter of 2010, accounting for 1.4% of its overall sales.
Other figures suggest there are about 500,000 overall BlackBerry users in the UAE and more than 700,000 in Saudi Arabia.
The market is tiny for RIM but obviously big enough to worry the governments of the countries involved.
