Bouygues Telecom, using its other brand B&YOU has launched a new revolutionary (for France) prepaid offer!
- € 0,10/min for national calls
- € 0,05 for national SMS
- € 0,05/MB for data
- € 4.99 starting kit (including € 1,50 of credit)
...and, most important: unlimited validity, you just need to use it (paying event) at least once every 12 months.
The only drawback is that it's only sold online so it could be complicated to get it for a foreigner...
