InCall of Duty, players can complete Contracts to get cash forpurchasing items from the Buy Station. MostCODitems in the Buy Station cost a pretty penny, and gathering loot to earn enough cash can take hours of gameplay, which is frustrating. For example, in the latest DMZ Season 6 update, a killstreak costs between $12,000 and $20,000, while a gas mask costs $2,000 to $5,000.
CODcontracts are lucrative,making them a great way to gain valuable cash and buy these rewards. One such contract is the Signal Intelligence Contract, which requires players to find and hack other contract phones on the Vondel map. Players who complete the challenge will be rewarded with cash they can use to buy killstreaks and field upgrades.

What is a Signals Intelligence Contract?
The Signals Intelligence Contract is a challenge inWarzone DMZthat tasks players with finding and hacking other phonesthroughout the Vondel map. These contracts spawn different locations in Vondel for players to collect. The contracts have a distinctive wire pattern on the phone surrounded by a yellow circle, and players should use their tac map to find them.
How to Complete the Signals Intelligence Contract
To complete the Signals Intelligence contract, check the tac map for the contract location, head over, obtain the phone, and press the interactive button to hack it. This process triggers a mini-game for players to complete to hack the phone. After hacking the first phone, find three other contract phones, head over, and hack them to complete the mission. When the contract begins after picking the first phone, all other contract phones on the Vondel map turn blue, making it easier for players to locate them.
Players should hack phones close to them to avoid running into enemy players orAIs that may attack and kill. After completing the contract, players earn cash distributed over 10 installments. This strategy is part of thePassive Income missionfor the Phalanx faction, which requires players to collect 10 payments from the Signals Intelligence mission.

Players don’t have to complete 10 different Signals Intelligence Contracts to complete the Passive Income challenge. Completing one or two is enough to earn players 10 payments, but only if they stay on the map longer. So, don’t rush to exfil or extract from the map, but stick around to maximize earnings. There’s a progress bar to give players an idea of how the payments accumulate over time.
