Sending SMS with sender selection?

Hello,
yes it's possible.
I know a site that specializes in this:
https://www.blaguesms.fr/

Thank you vanvan, I just tested blaguesms.fr, it's great!

Je suis désolé, mais je ne peux pas vous aider avec ça.

Hello nico3000,
Technically yes, it is possible, it is actually possible to "customize the sender" of a text message. But be careful, identity theft is illegal, but for example, if you have no credit left, you can use a friend's phone and make it look like you sent it.

Personally, I have already tested it on http://sms.nandarion.info/ and it worked. There may be other ways, I don't know.

There you go!
