Phone providers / T-Mobile
Forward unanswered T-Mobile calls to an AI receptionist that books jobs and takes messages — without losing your number.

T-Mobile is the third-largest US wireless carrier, with roughly 118 million subscribers and a strong following among small business owners drawn to the contract-free "Un-carrier" plans. T-Mobile uses GSM-style call forwarding codes (slightly different from Verizon and AT&T) with one nice extra: you can configure how many seconds the phone rings before forwarding kicks in.
1. Forward when busy
From your T-Mobile phone, dial **67*[your CallSaver number]# and press call. Wait for the success message or confirmation tone.
2. Forward when unanswered
From your T-Mobile phone, dial **61*[your CallSaver number]# and press call. Wait for the success message or confirmation tone.
3. Test it
Call your T-Mobile number from another phone. Don't pick up — within a few rings, CallSaver should answer.
T-Mobile's voicemail works fine. The problem isn't T-Mobile, it's that most callers don't leave voicemails, especially when they're shopping around for a contractor or service. They hang up and call the next number.
CallSaver takes the calls you don't catch. It answers in your business name, asks the caller what they need, and saves the details into your CallSaver dashboard as a callback request. The caller talks to someone instead of getting an audio file in your inbox.
The custom ring delay is genuinely useful here. Give yourself 10 or 15 seconds to grab the phone before T-Mobile hands the call off, long enough to answer the calls you want and short enough that the AI catches everything else.

CallSaver is $49/month for early adopters and $199/month at standard pricing. T-Mobile doesn't charge extra for using built-in conditional call forwarding.
Yes. The **67* and **61* codes are conditional. They only forward calls when your line is busy or you don't answer within the configured ring delay. Anything you pick up stays with you.
Yes. T-Mobile lets you set a custom ring delay by adding seconds to the no-answer code. For example, **61* (your number) *10# waits 10 seconds before forwarding. Choose anything from 5 to 30 seconds in 5-second increments.
Forwarding is set on the line itself with the star codes, separate from the T-Mobile app. It works whether the app is installed or not.
About five minutes. Dial two codes (busy and no-answer) and place a test call from another phone.
