Since beginning operations in 1999, Dollar has evolved into a company known for its superior product, impeccable quality and very competitive pricing. The former being the three cardinal principles upon which Dollar built its business model and thus its employees', vendors' and distributors' trust and confidence. Dollar has metamorphosed from its early days of simply being a small pre-paid phone card distributor to a multinational corporation offering telecom services to the prepaid phone card industry as well as a serious player in the wholesale field of telecommunications, servicing recognized conglomerates such as IDT, Bezeq International, Singapore Telecom, Arbinet, Teleglobe, Reach USA and a host of others via its own switch platform.
