("MOS" or "the Company")

Streams Mexico service exceeds subscriber target by 250%. Over 3,500 subscribers now signed up in first month alone.

Mobile Streams plc, the AIM quoted mobile content and data intelligence company, is delighted to announce that its LiveScore service in Mexico, which was launched at the end of July, has exceeded its August subscriber target by 250% with over 3,500 subscribers now signed up. Based on this number of subscribers, we estimate that this service in Mexico alone should generate at least $1.5 million over 3 years in additional revenue for the Company.

Users of the service are charged one dollar each week via their phone bill and then revenue is passed directly to MOS on 30 day terms from our Mexican telco partner Telcel. With a combination of a very easy sign on and billing process aligned with ever greater content delivered via our Streams platform and partnership with Quanta we estimate the number of subscribers and revenue growing significantly over the coming months.

Following on from our successful Mexican launch the Company is in advanced discussions on launching this service in several additional markets over the coming months. A further announcement on this will be made as soon as appropriate.

Andrew Deeks, CEO of QMG, said:

"We are delighted with the great take up of the service in Mexico, it clearly demonstrates the appetite for the offering and we expect subscriber numbers and revenue to keep growing significantly in the weeks, months and years ahead."

Nigel Burton, Non-Executive Director, said:

"We've been extremely pleased with the results to date. Although this is just the start, we believe this service will generate significant revenue for the business. Indeed the August launch figures alone are very impressive."
