I just found out that globe has a new offering as an altenative option for the 0.15 centavo per KB service. They have a 5 pesos for every 15 minutes. Something similar to smart's 10 pesos for 30 minutes. 

To avail of that, you need to send a message 'time' to 1111 to  switch to that feature.

A smart employee did say that you have to be wary about that because if it gets disconnected, they will charge you another 5 pesos. I have no information about that at this point so caveat emptor.
