Thanks to comprehensive and innovative solutions, IMS S.A. successfully promoted the sales offer of the Orange network mobile phones. As part of the project for Orange, we have prepared an advertising campaign broadcast on the in-store radio in 146 shopping malls throughout Poland. The purpose of the promotion was to support the sale of two phone models: Samsung and Sony Xperia, along with the offer of receiving a free half-year subscription for those who transfer their phone number to Orange. Additionally, activity in the in-store radio media was an extension of the advertising campaign used in other media. The highest quality of sound coming from the speakers and a properly tailored advertising campaign were a guarantee of sales success. Potential buyers could hear the offer close to the showroom. Effective advertising prompted them to act impulsively. This solution made it much easier for brand customers to make purchasing decisions.
