US Cellular uses standard GSM MMI codes for conditional call forwarding — the same codes that work on AT&T and T-Mobile.

**62*NUMBER# - Cancel all forwarding:
##21#
Replace NUMBER with the destination phone number (e.g. your VettedCalls extension). Dial the code from your regular phone keypad and press send. Listen for a confirmation tone.

How to use these with VettedCalls
VettedCalls is an AI call-screening service. When you sign up, we provision a dedicated screening number for your business. You then dial one of these forwarding codes from your cell, replacing NUMBER with your VettedCalls number. After that, every unknown caller routes through VettedCalls' AI — real customers reach you with name, intent, and urgency; spam stops at the gate.
