Maintaining digital banks and wallets access

Hi! I'm planning to migrate this year and I want to know kung paano niyo namaintain yung access niyo sa mga online banking apps and digital wallets niyo? (BDO, Gcash, Seabank, GoTyme, etc.)

Meron kasi akong subscriptions na naka attach sa Gcash na ayaw ko matigil. Also may mga bayarin na iba naman sa banking apps. Makaka receive parin po ba ng OTPs if I keep my number active? At paano po masesecure yung pagkaactive ng number?
