Starting with basics, many apartments, office spaces, villas etc do do have telephones because the cables have not been laid, in some cases to the "block" and in others from the blocks junction box to individual premises.
If you require a telephone line we advise you to check if there is an existing line in a location before you consider moving there, installation costs for new cabkes can be extremley expensive and effectively prohibative.
Equally important no physical telephone lines means no physical connection to the internet is possible.
If you are able to receive a signal on your mobile you could just purchase a pay as you go mobile phone service from Telefonica or Vodafone, both of whom have shops in Playa del Ingles.
Simple purchase a SIM card ( you also get a new Spanish number for people to call you on) and put that SIM card in your existing mobile; that way all calls you make locally will be only via local providers and will be much cheaper than using a mobile number from another country.
