Ang dapat lang tandaan, dapat ang dalawang pinagko-combine na promos ay may common denominator sa isa't isa. Meaning, dapat ay pareho sila ng content para maghawahan. Meron tayong walong contents:
Bulk texts to Globe/TM/ABSCBN/Cherry
Unlimited texts to Globe/TM/ABSCBN/Cherry
Bulk texts to ALL networks
Unlimited texts to ALL networks
Bulk calls to Globe/TM/ABSCBN/Cherry
Unlimited calls to Globe/TM/ABSCBN/Cherry
Bulk data
Unlimited data
BULK is not the same as UNLIMITED when it comes to combining promos. Iba po ang bulk texts sa unlimited texts at hindi masasabing compatible ang dalawang yan in combining promos. Kaya kapag nag-register ka ng dalawang promos with one having bulk texts while the other one has unlimited texts, hiwalay din po sila pag nag-check ka na ng status and they will be treated as a separate/different content. The same applies to calls and data.
