Getting on-line
There are a number of ISPs (Internet Service Providers) here but getting connected is not as easy as in the UK where you can stroll into any supermarket and pick up a disk that will have you going in minutes.
First Dial-up.
Telefonica are the easiest to get a disk for if you want to get yourself going, just call in your nearest Telefonica shop, remember it will only be in Spanish. The more popular choice for a dial-up connection out here is Gonuts4free, this is because they are the only one who will give you support in English at your first 'phone call. You can download a setup disk from http://www.gonuts4free.com/internet/download.html or you can contact one of the many PC engineers who are plying their trade up and down the coast. If you take the call a technician option then make sure you get a firm price before you tell him to come to you. Sadly there are a few bad apples who will try to take advantage of your lack of knowledge and experience. You should not pay more than €30 for this service.
Now ADSL (Broadband)
Yes your broadband has a different name here, don't expect a Spaniard to know what you mean by broadband they won't. Even worse they don't say Ay-Dee-Es-Ell it's ah-duh-es-ell. Only one provider offers an English installation disk (Europa), unfortunately I've never seen the english disk work and you always end up going back to the spanish disk. All the providers will supply you an installation kit with either a router or modem, filters and a setup disk. The cheapest supplier at the time of writing is Ya who are part of France Telecom and you can order on-line at http://acceso.ya.com/ADSLllamadas/3mbvoz/ if your spanish is up to it. If you choose to sign-up with Ya then be aware that they require you to activate the service in spanish by telephone, you therefore need to have, or have someone with excellent spanish. Other suppliers include Telefonica, Gonuts4free, Europa Network and Orange. They all include all your Spanish national and local calls. Telefonica will charge you up to €100 to send an engineer to do the installation for you and the others will insist you do the installation yourself. Whoever you go with, your local PC engineer will be able to do the installation for you and should charge no more than €30. Don't get suckered by the offers of very wide bandwidth at very low prices all these people have on their websites. Unless you live in one of the largest cities (Madrid, Valencia, etc) then those deals will not be available to you. The best offer I know of is currently with Ya.com who are offering 1Mb/s for €19.95 see websites for a link.
BT ADSL in Spain is the Arakis service and is nothing like the broadband they provide in UK.
Roundtown news network is really Europa in disguise. The cheap offer of ADSL they offer, like the Europa offering is dependent on you making a large number of 'phone calls each month.
If you have elected to live in the back of beyond then it is quite possible that either there are no phone lines or if there are then there is no ADSL. In this case Vodafone do offer internet connection via a USB dongle that gives a reasonable connection speed for around €40/month. This device requires you to call Vodaphone during installation to obtain a PUK (Pin Unlock Code) so you need a spanish speaker with you for a few minutes. Orange have a similar service but the coverage is not so good and you can end up with connection speeds slower than dial-up. Telefonica also now sell a USB dongle to provide mobile access but only on contract.
Don't be surprised if your email address stops working when you connect from Spain. Most providers in the UK will not allow you to send emails if you are not connected through their connection. So your @tesco.com, @freeserve, etc addresses will be no use to you. Before you move the best thing to do is get a web based email service such as Hotmail, Gmail or Yahoo, personally I like Gmail best it gives you far more of everything than the others.
