I have so far heard from users that PTCL is way better than other in the competition and has far better coverage areas. Speed is dependent on areas and other factors which may effect signal reception.
PTCL is offering the device for free since late March and due to this offer many are switching to it. I haven't have direct feedback of Wifi cloud user, still though, I would be getting one within the offer deal....hope this serves the purpose....I will be fine as long as it maintains a net surfing speed of 1Mbps and over.
