Customer feedback

I have been with your service for more than 1 year, it is great, your support department is very fast. The rates are very cheap, the unlimited plan is amazing to call different countries. The calls have a high quality audio. All is perfect including the pbx system that you provide for free for a couple of months. Thanks, 5 starts to zadarma.

Ever since I discovered your system international calls have been less costly for us. Your system is really a stress reliever. We used to pay so much but now, with good internet access, we save a lot of money. Thanks for your service. Will recommend it any day to anyone.

I think Zadarma is a great solution for every business, it is simple to use and it offers a great PBX for free. Zadarma offers a lot of virtual numbers (local and toll free) in many countries and helps our customer support.
