Is the prize awarded by the telecommunications company for charging the balance with a certain amount permissible or impermissible?

Prizes offered by companies to promote their products are permissible if certain conditions are met, including: that the consumer purchases what they need at its market price without any increase. The resolution of the Islamic Fiqh Academy states that there is no objection to prize providers benefiting from promoting their goods through competitions, provided that the value of the prizes or part thereof does not come from the contestants, and that the promotion does not involve deception, fraud, or betrayal of consumers. Accordingly, there is no harm in participating in the draw if these conditions are met; otherwise, participation is forbidden.
