Globe recently released the Duo plan. For 399 pesos (good for 30 days) you will be able to make unlimited calls to and recieve unlimited calls from landlines and other Duo subscribers. They will assign a landline number to your globe cell so your phone will have two numbers, one globe cell number and the mobile landline number.

To activate your call forwarding, you need to type *72#632 and then the 7 digit number before sending send. However, this only works if youre forwarding to a bayantel landline or a cellphone.

 To deactivate, send *720

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.
