It's quiet different!
If, the telecom operateur treats you as its staff, this salary is very nice ! In this case, your contract in France is CDD(google it for more information). And the company will charge sth more then your salary like your social security etc. And at the end of this work, you will have a bonus at least 10% than your salary.
In other hand, if the company treats you as a freelance, this salary is too poor to be accepted! Because in this case, it’s yourself charge lots of charges as the mutual and social insurance…
