IMPROCOM provides great and reliable service with perfect sound quality, price and customer service was very helpful. The technical support service was outstanding, they helped me with everything which I asked very quickly. I highly appreciate all the help, which was given to myself. The equipment system was great. Everything was heard very clearly throughout the call. The call did not drop even once, which is greatly appreciated, since these services have a tendency of doing that sometimes. I would be honored to give people referrals of you company. Thank you so much for all you help.

I am a photographer and need to make a lot of international calls to either overseas clients or to the locations where the weddings takes place, as well as the clients all over the US. I was looking for a stable telephone service with the good quality calls and an easy to reach tech support in a case of emergency. I stumbled upon Improcom's website on Google while searching for Voip service providers. The sales department was very thorough about the services and their equipment and prices. The sign up process was fast, and after couple of days I have got the phones and was ready to roll. I have never used the VOIP before and to my surprise the quality of sound was great and still is until today. The price is reasonable and so far I am a happy customer.

Don't be fooled by the 5 star reviews, TierZero is about getting you locked into a 3 year contract. They will charge you the full amount for 2 years no matter what happens and then 50% of the third year. If you need reliable internet, look elsewhere. After a year of subpar and slow internet, I finally just gave up and paid for 2 years of service I will not use to go with someone else. They were completely unwilling to work with me on a settlement at cancellation. They even admitted their service could not compete with what others were offering me and still was unwilling to work with me at all. Simply put, this is the worse of the worse and avoid them at all costs.

We have been operating an online retail business for several years and have recently opened a physical retail store and a separate warehouse for wholesale order fulfillment as well. We really wanted to move into a VoIP system and connect all the locations. We tried several companies with minimal success until we were referred to Tierzero. The line sound quality is truly superior and much better than what we were getting from the other providers we tried. More importantly the hands on customer service we received was really outstanding. There were some initial problems that were quickly resolved and each time we called in for assistance, the level of professionalism and quick resolutions to our issues was something we had not experienced before. We are very pleased with Tierzero and would highly recommend them.
