As per Fair Usage Policy

So based on the policy, you can still use your data or internet even you already reached the threshold though at the slower speed nga lang. So basically "unlimited" surfing ka pa rin di nga lang yung the usual speed.
Di lang slow, SUPER slow. 0.5 kbps ung sinasabi nila. Kahit FB aabutin ka ng 2-3 mins. bago lumabas ung mga icons sa fb. -_-
Additionally, Globe's new promos are avoiding the word "unlimited" in their ads.
