I have Telecom BB Adventurer with Total Home Plan, $120 or something for 20GB and have been very happy with the speed, reliability and service.
Today some guy from Telecom knocks on my door to offer me a doubling of data for 12 months to 40GB for no cost. There seems to be no catch...so I signed. Definitely no change to contract.
Seems great. Is there a catch anyone knows of?
