What is the ruling on obtaining a free phone or credit from a telecommunications company in exchange for subscribing to an advertising program?

It is permissible to own the incentives and gifts provided by telecommunications companies to targeted individuals, because they are free promotional gifts devoid of Sharia prohibitions. Likewise, subscribing to the (Mobida) program is permissible, as its function is advertising and promotion, and the original ruling for gifts is permissibility, as is advertising and promotion, even for a fee, provided that the Sharia guidelines for advertisements are observed.
