Got the MX newsletter yesterday. Video shortcodes and MX are more or less synonymous. They’ve been running service on some networks for quite a while, but only recently have they been able to provide service to most of the UK networks:
Video Short Codes have been live for some time on 3 UK and Vodafone UK, and have recently launched on Orange and T-Mobile. As the penetration of 3G handsets rises both in the UK and worldwide, we at MX Telecom are very excited at the prospect of Video Short Code services taking off both here and abroad, and urge our clients to seriously investigate Video Short Codes as mobile video strides towards the future.
