How to forward calls on US Cellular

Human Add AI help center covers call forwarding setup for every major US carrier (Verizon, AT and T, T-Mobile, Spectrum, Comcast, RingCentral, Google Voice, OpenPhone, and twelve more), PWA install instructions for the mobile dashboard, knowledge base editing, and account management. Most setup guides take under five minutes to complete.

US Cellular uses standard star codes for call forwarding, the same family of codes Verizon and the older Sprint network used. This guide shows you exactly what to dial, how to test it, and how to turn it back off, plus what to do if your line is on the new T-Mobile network after the 2024 acquisition.

The quick version

On your US Cellular phone, open the dialer and enter *72 followed by the 10-digit number you want calls forwarded to, then press call. To turn forwarding off, dial *720. If you're on a US Cellular line that has migrated to T-Mobile's network (most new SIMs after Q4 2024), use **21* followed by the 10-digit number followed by # instead.

Step-by-step: enable call forwarding on US Cellular

1
Open the phone dialer app on the US Cellular line you want to forward. You enter the star code the same way you'd enter a phone number, in the regular dialer.
2
Type *72 followed immediately by the 10-digit destination number. No spaces, no dashes, no +1. Example: *725551234567.
3
Press the call/send button. You'll hear two short confirmation tones, then the call ends automatically. That's the signal forwarding is active.
4
Test it. From a different phone, call your US Cellular number. It should ring at the destination, not your cell. If it rings your cell, give it 60 seconds and try again, or scroll to the troubleshooting section below.

To turn forwarding off

Open the dialer, enter *720, and press call. You'll hear a confirmation tone. Your line is back to normal immediately. If you're on the newer T-Mobile network SIM, use ##21# to disable instead.

Conditional forwarding (busy, no-answer, unreachable)

Sometimes you want to handle some calls yourself and forward only the ones you miss. US Cellular supports three conditional forwarding modes:

Most service businesses just want unconditional forwarding (*72) when they're using an AI receptionist or answering service, because you want every call to land somewhere reliable. Conditional forwarding is for situations where you want to take some calls personally.

If your US Cellular line moved to T-Mobile's network

T-Mobile finalized its acquisition of US Cellular's wireless operations in late 2024. New SIMs and many existing lines have been migrated to T-Mobile's network, which uses different forwarding codes. If *72 doesn't work on your line, your line is probably on T-Mobile's network and you should use these codes instead:

To find out which network your line is on, check the carrier name in your phone settings. iPhone: Settings › General › About, look at "Carrier". Android: Settings › About phone › Status. If it says "T-Mobile", use the T-Mobile codes; if it still says "US Cellular", use the original codes.

Using the My Account app instead

The US Cellular My Account app does not currently expose call forwarding controls for individual lines. The star codes above are the canonical way. There's also a web portal at uscellular.com, but the call-forwarding option there is limited to landline products and not wireless lines. Don't waste time looking for a toggle in the app, just use the dialer codes.

Things worth knowing

Forwarding to an AI receptionist?

The reason most people search for "how to forward calls on US Cellular" is they're tired of missing calls and want a real solution. If you're forwarding to a voice assistant, an answering service, or an AI receptionist, the steps above are the same, you just enter their number as the forward-to destination. Human Add AI gives you a dedicated AI receptionist that answers 24/7, captures every caller's intent, books appointments, and texts you the details immediately. Try it free for 7 days →

Plan tiers and what changes between them

The Human Add AI pricing page lists three tiers, and the differences between them come down to three axes: how many inbound calls per month, how many physical or logical locations are routed by the same agent, and whether outbound calling is enabled. Starter at $497 monthly handles up to 250 inbound calls, a single location, and inbound only. That works for the smallest single-truck operations, solo professionals, and any operator who wants to pilot the platform before scaling.

Professional at $997 monthly is where most service-business operators end up. The 750-call ceiling is generous for any single-location business with normal inbound volume, the multi-location routing lets a business with two or three offices share a single agent with location-aware booking, and the deeper CRM integration matrix removes the manual hand-off step between the receptionist and the field-service software. Professional is also the tier where the SLA tightens on the response-time guarantees and on the build-tuning cadence after launch.

Enterprise at $1,997 monthly is for high-volume operators who want unlimited calls without watching a meter, white-label phone numbers, a named tuning contact at Human Add AI, and the outbound module. Outbound calls billed at fourteen cents per minute give the platform missed-call callback, appointment reminder, lead-nurture, and review-collection use cases. The outbound meter is visible in the dashboard with a hard-cap option for any operator who wants to bound monthly spend.

Across all three tiers, the conversation quality, the booking automation, the CRM sync, the SMS lead alerts, the call recording with searchable transcripts, the dashboard, and the support team are identical. The platform is engineered so a Starter customer should never feel like they are using a worse product, only a smaller-volume version of the same product.

Frequently asked questions

How fast does the AI answer the phone?

Every inbound call is answered inside two rings. The agent picks up before voicemail ever triggers, which means a service business never loses a lead to "they did not pick up, so I called the next listing." The two-ring pickup is hard-coded into the platform and is the same on Starter, Professional, and Enterprise plans.

What happens if the AI cannot answer a question?

The agent is built with explicit fallback rules. If a caller asks something outside the trained scope (a complicated insurance question, an unusual scheduling request, a pricing question for a service the business does not offer), the agent says so plainly and offers to text a member of the team with the caller's number. The text arrives on the on-call phone within seconds, with the caller's name, number, and a summary of what they wanted.

Can the AI book appointments directly on my calendar?

Yes. The agent reads the live availability on your Cal.com, Google Calendar, Calendly, Acuity, Jobber, Housecall Pro, ServiceTitan, or other booking system and offers the caller real slots. When the caller accepts a slot, the agent confirms the address or the service location, sends a confirmation text to the caller, drops the appointment onto your calendar with all the intake details in the notes field, and texts you the booking summary.

Does the AI work after hours and on weekends?

Yes. Human Add AI runs 24/7/365 by default. The agent answers every call regardless of time, qualifies the lead with the same questions a daytime receptionist would ask, and either books an appointment on the next available business-day slot or texts your on-call dispatcher if the call qualifies as an emergency. Roughly 35 percent of service-business calls happen outside Monday-to-Friday 9-to-5, and most of those are still booking-quality leads.

What CRMs and booking systems does it integrate with?

The platform integrates natively with Jobber, Housecall Pro, ServiceTitan, FieldEdge, mHelpDesk, Workiz, RazorSync, Cal.com, Google Calendar, Calendly, Acuity Scheduling, HubSpot, Salesforce, Pipedrive, Zoho CRM, Clio, Lawmatics, Lawyaw, MyCase, Practice Panther, Dentrix, Open Dental, Eaglesoft, Curve Dental, ServiceM8, and twenty other vertical-specific systems. If your CRM is not on that list, the team will build a Zapier or webhook handoff during onboarding.

Is Human Add AI HIPAA compliant for medical and dental practices?

Yes. Human Add AI signs a Business Associate Agreement on the Enterprise plan and routes all medical and dental conversations through a HIPAA-compliant pipeline with encryption in transit, encryption at rest, audit logging, and seven-year retention controls. The standard intake questions for medical and dental practices avoid collecting protected health information on the phone and route triage decisions to the on-call clinician.

What happens if I want to cancel?

Plans are month-to-month with no contract. Cancel anytime through the dashboard or by emailing info@humanaddai.com. Your forwarding number stays active through the end of the billing cycle, the dashboard exports every call recording and transcript as CSV plus MP3, and there is no off-boarding fee. Most operators do not cancel because the platform pays for itself in recovered missed-call revenue, but the option is always one click away.

How is this different from a virtual receptionist service?

Human virtual receptionist services like Smith.ai and Ruby Receptionists charge per minute or per call, which means costs scale with success. A busy week can cost more than the entire Human Add AI monthly plan. Human virtual receptionists also have a small staff pool, so callers reach a different person every time, and the receptionist does not know your vertical. The Human Add AI agent is custom-built for your business, costs the same flat price no matter how many calls come in, and answers every call the same way with the same accuracy.
