Be Unlimited (also traded as Be There or simply BE and latterly known legally as Sky Home Communications Limited) was an Internet service provider in the United Kingdom between 2004 and 2014.

[4] BE offered ADSL2+ broadband services through BT's telephone exchanges via Local Loop Unbundling (LLU), with advertised speeds of up to 16 Mbit/s downstream and 1.9 Mbit/s upstream, subject to Annex M enablement, line length and quality,[5] making BE's network the fastest mainstream, and first[6] ADSL2+ ISP in Britain during its nine-year existence.

BE's service utilised ADSL2+ (ITU G.992.5) and was one of the few UK ISPs to offer the Annex M extension to increase upload speeds anywhere up to the full technical maximum of ~2 Mbit/s for its BE Pro customers.

The result was that a user with a dynamic IP address could only use BE's own SMTP server or one configured to use non-standard ports for sending email.

This, coupled with the fact that there were officially over three times the number of subscribers using the platform since the launch of O2Broadband,[12] caused some BE users to voice concerns over the future performance, stability and contention of the service.

[14] The first of these companies was Vaioni,[15] which launched an "up to 20 Mbit/s business class ADSL2+ service" featuring up to 2.5 Mbit/s upstream and a guaranteed 10:1 contention ratio with prices starting from £140.99 per month.

In August 2009 the UK ISP Andrews & Arnold entered into an agreement to use BE's core and LLU networks to augment BT's legacy 20CN and 21CN infrastructure.

[17] In late June 2011, BE's managing director Chris Stening announced a fibre optic service to directly compete with BT Infinity.

[18][19] BE updated customers on their progress in September 2011; but whilst receiving 'thousands' of pre-registrations, as of late 2011 they had yet to partner with a suitable company operating a national fibre network to allow them to offer the level of service desired.

To try and accommodate some of their concerns Sky worked to integrate both static IP addresses and control over line profiles into their own network and launched this new service as 'Sky Broadband Unlimited Pro'.
