Zadarma's range of supported VoIP features provides excellent value. In particular I find that their virtual number deals make sound business sense. By taking virtual numbers, small and medium size firms are able to compete on international markets in a way previously only open to large companies. For example, from my office in the USA I can open and run virtual offices in the UK, India, Russia and many other leading business centers. It saves a small fortune in office, personnel and travel expenses while tapping into growing markets. I also find their free cloud PBX (they also call it a business phone system) brings many benefits to both the employees who communicate through it, and customers who call the firm. Since they can receive calls on a desktop computer, IP phone and smart phone, or forward these calls to mobiles and landlines, those important business calls no longer get missed. In my experience, customers certainly appreciate a positive calling experience. This significantly increases the possibility of that customer placing an order and coming back again to make subsequent orders. Finally, there is no denying that the cost savings are a big attraction. It is hard for landline service providers to compete when they have to carry the heavy costs of phone cabinet and wiring installations and repair. This VoIP service seems to me to be a much more economical choice without compromising on call quality.

I was able to receive International SMS from Israel cheaply. The account verification process and the support ticket process are cumbersome and wearisome to pursue.

I have saved money by having a phone number in a far country. This also encouraged people in that country to call me easily because for them they make local phone calls. I think Zadarma is an outstanding company that must be appreciated and supported in order to continue. It did make my life a lot easier, personally and for business. And I am sure it is helping many others too.
