Vodafone BlackBerry users in Europe, the Middle East and Africa have been experiencing connection issues, leading to disabled data services on devices.
Vodafone said in a statement that the firm is aware that some BlackBerry customers are experiencing issues and it is working closely with Research in Motion (RIM) to bring back full service as soon as possible.
"The issue was caused by a router error. Services are in the process of being restored," the firm said.
"We apologise to customers for any inconvenience caused and we will provide updates as necessary."
The current issue follows two interruptions in Research in Motion's (RIM) operations in the past 16 months and comes prior to the firm's plan to release its BlackBerry 10 phones on 30 January 2013.
RIM said in a statement: "All BlackBerry services are operating normally but we are aware that a wider Vodafone service issue is impacting some of our BlackBerry customers in Europe, Middle East and Africa."
According to sources, RIM's devices used through South Africa Vodafone's Vodacom were also affected by a connection outage, while UK users revealed that BlackBerry Messenger has been down along with email.
The last outage of RIM's network occurred in September 2012.
