Everywhere in the world I go, I rent a pocket wifi.
For my one month trip to Spain, Wifivox was my very best friend. It served me well as I ate my way through Seville, Cordoba, Granada, Barcelona, San Sebastian, Burgos, Madrid, Toledo and Segovia.
Ordering is easy. Go to http://www.wifivox.com, enter details, pay by credit card, and your device will be delivered to the address of your choice.
I had mine delivered to my first hotel of the trip and it was already at the reception upon check-in
The package contained the pocket wifi, a case, charger, manual, and a stamped return envelope
Woohoo! Unlimited internet connection every second for the duration of my trip!
Returning the device was even easier.
Just drop off the package at any post box or hotel or airport or Wifivox store.
I dropped mine off at the Madrid Airport after checking in for my flight and right before
I went in to immigration.
Hope this helps everyone traveling to Spain!
