London UK – 20th August 2008,

Following last week’s announcement that UK MVNE CallKey had shipped over 200K SIMs, it was disclosed today that a merger with one of it’s leading competitors, CallBlue has been successfully completed.

This merger results in CallKey expanding its network capability with the addition of an HLR (Home Location Register), and MSC (Mobile Switching Centre). This combination expands CallKey’s ability to act as a full MVNE (Mobile Virtual Network Enabler) providing the technology and services to facilitate companies to become full global roaming MVNO’s in a very short time.

By owning the technical infrastructure that underpins the service, unlike other roaming providers, CallKey has complete control over call costs, quality, security and billing. Callers always receive the best quality because all calls are switched directly from the home network.

CallKey is one of the world’s first and largest suppliers of Travel SIMs, which abolish high roaming fees that are usually charged by incumbent Mobile Network Operators (MNOs).

The company offers a 100% white label platform where MVNO’s can customise everything as their own, including having their own branding of SIMs and web portal, plus customised audio prompts and short-codes.  MVNO’s can set up multiple sub-distributors, each with their own discrete pricing, and customisation.

Each MVNO is also given access to their own personal “back office” where they can fully manage their customer and sub-agent accounts, plus view all CDRs in real time. A comprehensive online diagnostics facility provides necessary information for customer support.

CallKey also provides a full A-Z wholesale rate sheet optimized for various regions, including the EU, where MVNO’s can set their own tariffs, thus determining their profit margins. By offering free inbound calls in over 50 countries and cheaper outbound, MVNO’s are able to target corporate and leisure travellers, and genuinely compete against incumbent Operators.

CallKey offers full customisation options, where its core technology can be applied using standardised toolsets defined in an API (Application Programming Interface). The API allows a development partner or customer full network control.

Unlike other travel SIM suppliers, CallKey do not charge any MVNO set up fee, the only start-up cost being the initial purchase of SIM cards.

The company has roaming coverage in over 130 countries and only utilise the highest quality Tier 1 carriers. Each SIM can be reached by either calling a +44 UK mobile number, or as an option by dialling a local number available in various countries. Many premium enhancements include call forwarding, conference calling, call recording and voicemail. Access to a personal web portal provides online voicemail playback, a web dialling feature (with rates competitive with VoIP providers), and the ability to view call records in real time.
