This guide will let you know how to unlock and play the Payphone Hit Missions in GTA 5 Online. Go through the guide and follow all the instructions carefully to unlock it.
You will need to own an agency to play these missions. To unlock the payphone missions, you have to complete three security contracts when you have the agency. Go to your office to play the security contracts, and when you complete your first security contract, you need to call Franklin and request the next mission to start the next contract.
You first have to do the mission called Asset protection, where you have to stand still and kill all the enemies around you for ten minutes, as shown in the image below.
After completing three security contracts, Franklin will call you, and you will have the ability to find a payphone around the map. You can find the payphone as a phone icon on the minimap.
After finding the payphone and completing the first mission, you need to call Franklin and request the next mission by selecting the request payphone hit option.
There are 20 minutes of cooldown time between these missions, and also, you will get fifteen thousand dollars which is the base payment of these missions. If you follow the requirements of the client, then you can get a bonus from each mission which will be seventy thousand dollars.
