What about Cell phones – SIM with data service on the Camino de Santiago?

SIM card for your Camino de Santiago

The question was:

We took unlocked cellphones to Spain a couple years ago. No trouble getting cheap SIM cards (Orange) and they were used in both Spain and France largely to reserve ahead for Gites in France. I would have bought a data plan as well for email service but we were refused because we didn’t have a permanent Spanish address. We are returning to walk the Via Francigenia this fall. We should make it from England to the Swiss border. Has anyone else had this problem of buying a SIM card with data service? Will we run into the same problem in England? France? Any advice or guidance would be appreciated.
