Cancelling Iberbanda contract is not a problem.  You have the right to maintain your existing number with the new supplier, and the new supplier does the paperwork for you.  Iberbanda explained that it takes about two (or was it three?) weeks to go through the mill but I haven't found out who removes the old hardware and installs the new aerial andmodem.  I told Iberbanda that I had been offered a cheaper rate with another supplier and they immediately cut their tarrif by half and included 300 minutes/month to UK.  So, a better price that I was paying without the hassle of new contracts and hardware etc.  I shall remember to do that again in 6 months time and see if I can get it even cheaper.   Also - a chum rang Movistar to say he wanted out of his contract and wanted Pay-As-You-Go and they immediately suspended his monthly charge just to keep him on board.  That's my task for Monday !
