Service

Sims can use a telephone to call several different services, which will send NPCs to perform specific tasks. In The Sims, they arrive on foot, while in The Sims 2 and The Sims 3, they have vehicles. In The Sims 2, most service Sims will charge a per-visit fee in addition to their hourly rates. In The Sims 3, some service Sims charge by the day, instead of by the hour.

Routine Services
These services will have a fixed schedule once hired.

One-Time Services
These services will only come when Sims hire them.

Delivery Services
Sims can order delivery services anytime. They will deliver Sims' order in short time.

Emergency Services
Emergency services can be called any time during the day.
