“As for national roaming, the Ministry of Fun does acknowledge the difficulties. It cites the 2010 Ofcom paper, which says that seamless national roaming – where your call is handed over from (say) Vodafone to EE as you move along – is complex and expensive to implement, and reduces operator differentiation. It also hammers battery life, with the handset constantly looking for a better signal across any network it can find. That means a (roughly) tenfold increase in power consumption required for radio operators. (Note that this is only part of the overall power drain of a handset – displays and background data processing also consumer power – but it’s not a trivial part).
DCMS also acknowledges another difficulty: a handset would lose its weaker 3G or 4G signal after it glommed onto a stronger 2G signal. The user would lose their data connection – which is perhaps not what they wanted to happen.
Well-heeled rural communities vigorously fight the installation of equipment that improves their mobile communications – then complain that their mobile coverage is inadequate.
Perhaps it’s no coincidence that Prime Minister Cameron has a home in the Cotswolds – as Reg readers point out, Oxfordshire NIMBYs have been successful in ensuring coverage resembles a former Eastern European Soviet satellite. Do you want decent mobile coverage or do you want a village untainted by modern transmission equipment? Pick one of two.”

Its a costly and onerous process to get a single mast up.
