Has anyone bought a SIM card in BURGOS lately?

I bought a Orange SIM card (July 2013) with 1GB of data for a month for 15 euros and had to add 5 euros for voice/text credit at Madrid airport, I only made a couple of calls and used the data primarily, there were only a few places I could not get data service, If I were to buy a new SIM card I'd get this one

The wall plug splitter can be found at a local ferriteria (hardware store) and possibly the USB sockets as well. There are a few small electronics stores in the heart of Burgos by the cathedral.
People will tell you to rely on wifi, but I find it a pain to ask for the password at the cafe/bar/albergue, I was able to use my iPhone like I would at home, post FB photos, and check in when I wanted. The first thing most people do when they stop at the cafe/bar for their morning break, is ask for the wifi password when ordering their morning cafe con leche, it was like that every morning.
It was nice not to have to rely on wifi, you could call ahead or book a albergue/hotel at your convenience and not have to wait to get in a wifi zone.
If you have any more phone questions PM me.

If you have recently purchased SIM cards or data services, can you tell me what carrier you used, how much it cost, etc? I'm hoping to find the most recent rates. My camino begins in 2 weeks!

I also hope to find a wall plug that has 2-4 USB sockets on it, so that I can charge my phone and camera at the same time. (And hopefully have a socket or 2 available to share.) Can those be found in mobile phone shops?[/quote]
