Hi Jhun, sorry to inform you but globe doesn't retain number for prepaid accounts.
This is going to be a "suntok sa buwan" but what you can try is; first, go to your barangay hall so you can file for affidavit of loss. You need to indicate your lost number in the affidavit. Then, go to your nearest Globe store and tell them you lost your SIM card and you want a replacement. Tell them you only lost it recently so they could entertain your request. Don't tell them you lost it a long time ago. If lucky enough, they will be able to provide you with a new SIM card with your old number.
