So today I came across this:
- La Carte - SFR
It's the prepaid package of SFR. They have interesting "iPhone" options, which I assume can be used anywhere. It is €3 for 1 day or €10 for 7 days of unlimited internet.
Two uncertainties:
- What is the passive validity period? Does it expire with the speed of light, like the other French prepaids? Or can you buy it, use one day of internet, and then buy another €3 recharge for another day of internet 1 year later?
- Is the internet really unlimited?
