I've been on Icerbox for years and have no issues.
I've been on Icerbox for years and have never had a problem with charges or data rates etc. My only complaint is with their 50GB / day data cap but that isn't often a problem. Another nit: they count the full download size as soon as it starts, even though it may be aborted. So a couple of false starts can get me to the cap. They should only count actual bytes transferred. But no issues with the company as such.
