PTCL Unlimited Broadband

I have been told the 4 MB below packages are with shared speeds, and do not assure full speeds. PTCL acceptable policy is proving only 60% of the advertised speeds.

I want to know if anyone knows, 10 MB or above, also are shared connections or are they dedicated single connections?

All are shared but one usually gets full speed. Dedicated bandwidth has higher costs and SLAs to guarantee speed/bandwidth.
