I would advice you to have a better answer is to call directly the Globe Customer Service
If you are in Metro Manila you may dial 730-1000 using a lined phone or using your mobile phone dial 211 ( be sure that your balance is enough to call. Though calling is free but Globe required you at least having an airtime credit which is enough to call for 1 minute)
Under your contract you cannot DOWNGRADE your plan to a lower one if you are still locked in. Doing so would be subjected to pre-termination fees.
You are permitted to UPGRADE but not to downgrade.
@ChitoReyes could you please attach a screen captured or link of the "Terms and condition" with the following clauses :
a.) "Under your contract you cannot DOWNGRADE your plan to a lower one if you are still locked in. Doing so would be subjected to pre-termination fees."
b.) "You are permitted to UPGRADE but not to downgrade."
Proof or a screen captured clauses of term and condition could really help the other readers and followers.
