What I was happy with more than anything was honesty. We all remember United-mobiles months of brief interruption (the site last I checked finally expired) and celtrek's flame out. I have used Telna and have had clients use it. I was happy, the billing was easy for me to show my clients and all was good. I will not invest in another plan, but am willing to give them a shot when they are back on line.
Like some former providers, I guess I should change my sig! Just noticed the reference to a defunct company!
