SMS are not charged extra; they are included in the plan, I have unlimited texting. I don't see what app I could have installed... It's simply that these texts intrigue me.
SMS are not premium rated, not charged. There are many on my detailed bill, SMS to n0 SFR 777 Does anyone know what this is about? Thank you in advance.
If it's not someone in your circle, it's an application that you illegally acquired that sends premium-rate texts on your behalf (and if that's the case, you deserve it!).
