How can I add Franklin as a contact in GTA Online?

In GTA Online, to add Franklin as a contact, one would typically need to complete specific missions or tasks related to the character. After meeting certain prerequisites during gameplay, such as progressing through story missions, reaching a particular level, or participating in events where Franklin is a part of the narrative, he could become available as a contact in your in-game phone. Once Franklin is added to your list of contacts, you have the ability to call him for assistance or to engage in mission-related activities that are tied to his character. Keep in mind that Rockstar Games may change gameplay mechanics or introduce new content through updates, which could affect how characters like Franklin are integrated into GTA Online.
