Hi,

FREE Social Chat (aka Free Basic Internet) allows you to stay connected on all chat apps 24/7 for FREE, even when you have run out of quota at the speed limit of 64kbps OR without an internet pass. Hardstop only happens if Free Social Chat's Fair Usage Policy (500MB) is exceeded or your line is on grace\inactive status. Your FREE Social Chat will be fully activated within 1 hour after activation of your Hotlink RED Plan.
