Best wifi / internet / mobile in El Pinar area

Hi, me again. Whilst on hols we have been looking at providers in the area for internet, mobiles etc that cover off El Pinar.

We have spoken to friends and neighbours and have had suggested Next and also WiMAX. Just wondered what anyone else's thoughts were? We are looking for a good internet connection so that I can work and our son can play on his Xbox, plus a good mobile deal. 

We are also not sure on having a landline either. We hardly use it in England, preferring to use my mobile of facetime / Skype.....

Thanks in advance, Tina
