Are the prizes offered (mobile phones) real, and what is the ruling of Sharia concerning them if they exist, especially since no one has mentioned winning one?

The mobile phone prizes offered by the network are real and genuine, and the names of winners from different countries can be seen. The fact that some people do not receive them does not mean they do not exist, because the draw does not affect everyone. This competition is permissible by Sharia because it is a free service (free mobile messages) provided by the network to its users, and the participant loses nothing.
