What and who is the internet service in Rota Spain? I am hoping they have cable or dsl service. I am moving in Rota next summer. I hope is not a dial up. Thank you.

I think the cable provider in that area is ONO .

If you opt for DSL connections, then you can try any of these countrywide ISPs:
Telefonica
Wanadoo
Jazztel (English version Website)
Ya.com
Arrakis

All of them (and some other more) can provide you not only Internet, but phone service and, some of them, even TV service. In most of the cases, you would have to hire a Telefonica line, no matter you are using the services of the other companies. Telefonica is the old monopoly company and still owns a huge part of the Spanish wire lines.
