Here is an update on roaming and SMS in Europe. I wrote 2 months ago « they will decrease the price of SMS in Europe from 0.30€ to 0.13 (VAT included). » and I was wrong. The European directive was about roaming only and even if my operator (SFR) sent me a message stating that the price will be decreased for SMS sent from Europe zone, this does not include France.
After receiving my bill (containing 20 SMS from France to UK and 1 from UK), I got confirmation on the phone that SMS from France to Europe are charged 0.30 euro, and SMS from Europe to Europe are now charged 0.13 euro, because for them "Europe zone" means all European countries except France.
I still love this European directive, but I hate how mobile operators don't even try to look consistent in the prices, just to suck all the money they can.
Update: this is actually worse. On week days between 8 and 22, and on week ends, sending a SMS from France to France is 0.15 euro! So, sending a SMS to my operator's network from its own network is more expensive than sending it from abroad.
