Hi @franzkk56 ...
Is your plan the old plan or the "Best Ever" already?
Ordinarily, you may just ask Globe if you can have an upgrade and they will just tell you if you need to submit additional documents based on what you submitted before. Kung minsan, lalo na kung sufficient yung financial capability ninyo sa dating documents, hindi na kailangan.
Kung nasa "Best Ever" na kayo, pwede din na sa Plan 499 kayo (with 900 PV/month), then choose the unlimited surfing combo worth 999 PV/month so ang magiging monthly ninyo would be Php 598.00 lang (Plan 499 plus P99 where P99 is the difference of P999 unlimited surfing less 900 PV for the plan 499).
This is good if you just plan to use your Plan just for unlimited surfing. All other usage like calls and texts would be charged on top of that.
