So, unlimited data & calls for 19.99 €, with a reduced price of 15.99 € for customers of the broadband plan. And a specially priced 2 €/month plan (60min calls / 60sms.)
The first "2€" mobile plan is completely free if you are a broadband customer. This puts the family budget down to something very, very manageable. None of the plans include any sort of 12/24month lockout. Devices payment over up to 36months no additional charges.
Subscription for 1h voice + 60 SMS per month is free (as in free beer) for broadband customers. My kids will immediately get SIM cards! Prices available at http://mobile.free.fr
