The best part about telNum for me personally has been their customer support team! I have never had an issue with them in over 2 years of using this great product!! They are always willing/able topay attention when we need it most (and not just once!). There really isn’t anything bad i can say at all regarding my experience here as they provide excellent services without fail each time. Give some thought before deciding if your going through these guys or another vendor because there aren't any other options out in market right now aside from those mentioned above. !
