at800 is an organisation created to ensure that all UK viewers continue to receive Freeview, or are offered a suitable altern ... ative, when 4G at 800 MHz is activated in their area. We are funded by and represent the UK mobile operators licensed to offer 4G mobile services at 800 MHz: EE, Telefónica UK (O2), Three and Vodafone. at800 is a trademark of Digital Mobile Spectrum Limited (DMSL). To ensure we deliver a high quality service, we report to the 4G/TV Co-existence Oversight Board representing consumers, broadcasters, mobile operators and Ofcom. It monitors, advises and reports on our performance to the Department for Culture Media & Sport (DCMS). Read about our social media policy here: https://at800.tv/social read more
