CONTRACTOR TELEPHONY GUIDE

How to Forward Business Calls on Any Mobile Carrier

The complete reference for trade contractors. Keep your cell number, avoid missed customer leads while on tools, and set up conditional call forwarding (*71, *72, **004*) in under 60 seconds.

1. The Two Types of Call Forwarding

Before entering any dial codes, it helps to understand the difference between Conditional and Unconditional forwarding. Trade contractors almost always prefer conditional forwarding so their own cell phone still rings when their hands are free.

ALL-DAY / VACATION

Unconditional Forwarding (*72 or **21*)

Immediately redirects 100% of incoming calls to your receptionist without ringing your cell phone at all. Perfect for focused work days, days off, or family vacations.

2. Carrier Dial Codes Quick Reference

Open the phone dialer app on your smartphone, enter the activation code followed immediately by your 10-digit receptionist or forwarding number, and press the Call button.

4. Frequently Asked Questions

What if my carrier says "Feature Not Supported" or gives a fast busy?
A small percentage of consumer prepaid plans have conditional call forwarding turned off by default at the carrier switch. Simply dial 611 on your phone to reach your carrier's customer service and say: "Please enable conditional call forwarding on my line." Carriers do not charge for this feature and it takes 30 seconds for them to toggle it on.
Does forwarding calls use my cellular minutes?
Call forwarding uses your mobile plan's airtime minutes. Because almost all modern cell plans in the US include unlimited nationwide minutes, forwarding calls does not generate additional carrier fees.
How does FieldSmith Pro use call forwarding?
FieldSmith Pro provides an Android companion app that makes this 1-tap simple. When you start your workday, you tap "Forward Calls" in the app, and FieldSmith dials the appropriate carrier code automatically.
