Telefonica have not adopted residential femtocells very widely and this has mostly been restricted to their O2 subsiduary.
The Guardian newspaper reported in 2008 plans for a large early femtocell trial in the UK, following those already conducted in Czech Republic (where O2 operates both fixed and mobile networks) and Spain (within Telefonica's own labs).
They had a particular focus on office buildings, as stated in their quarterly newsletter
Huawei were revealed as the vendor. Their standard residential femtocell supports up to 4 concurrent calls. It was later revealed that Alcatel-Lucent are also providing their femtocell solution in parallel.
The service costs 9 Euros/month. A DSL broadband line from Telefonica is required and it must have a minimum download speed of 3Mbit/s.
