It was the stock's biggest, single-day, percentage price drop since September 2008. But shares were still nearly 80 percent above the year's low, which was reached in September. They started to rally in November as investors began to bet that RIM's long-awaited new BlackBerry 10 phones, which will be unveiled in January, would turn the company around.
The services segment has long been RIM's most profitable and accounts for about a third of total revenue. Some analysts said there was a risk that the fee changes could endanger its service ecosystem and leave the Canadian company as just another handset maker.
The fee changes, which RIM announced on Thursday after market close, overshadowed stronger-than-expected quarterly results. The company said the new pricing structure would be introduced with the BlackBerry 10 launch, expected on January 30.
RIM said some subscribers would continue to pay for enhanced services such as advanced security. But under the new structure, some other services would account for less revenue, or even none at all.
Chief Executive Thorsten Heins tried to reassure investors in a television interview with CNBC on Friday, saying RIM's "service revenue isn't going away". He added: "We're not stopping. We're not halting. We're transitioning."
