This guide covers how to forward calls from your Sprint phone to another number, like an answering service such as Upfirst. Sprint is now part of the T-Mobile network, but these star codes still work for Sprint customers. Below you will find the steps for immediate and conditional call forwarding on Sprint.
How to forward all calls from Sprint
Immediate forwarding sends every incoming call straight to another number without ringing your phone. Sprint uses star codes that you dial from your phone's keypad.
Turn on immediate forwarding
- Open your phone's dialer.
- Dial *72 followed by the 10-digit destination number (for example, *72 followed by your Upfirst number).
- Press the call button.
- Wait for a confirmation tone or beeps.
- Place a test call from another phone to confirm forwarding is active.
All incoming calls will now go directly to your Upfirst number without your phone ringing.
Turn off immediate forwarding
- Open your phone's dialer.
- Dial *73.
- Press the call button.
- Wait for a confirmation tone.
Your phone will ring normally again for all incoming calls.
How to forward only missed calls (conditional call forwarding) on Sprint
Conditional forwarding lets your phone ring first and only forwards the call if you don't pick up, your line is busy, or your phone is turned off. You can set up one, two, or all three conditions.
Forward when you don't answer
- Open your phone's dialer.
- Dial *73 followed by the 10-digit destination number (for example, *73 followed by your Upfirst number).
- Press the call button.
- Wait for a confirmation tone.
Your phone will ring for several seconds. If you don't answer, the call forwards to your Upfirst number.
Forward when your line is busy
- Dial *74 followed by the 10-digit destination number.
- Press the call button.
- Wait for a confirmation tone.
Calls that come in while you're already on a call will forward to the destination number.
Forward when your phone is off or out of range
- Dial *75 followed by the 10-digit destination number.
- Press the call button.
- Wait for a confirmation tone.
If your phone is powered off or has no signal, calls will forward automatically.
Turn off conditional forwarding
- Open your phone's dialer.
- Dial *720.
- Press the call button.
- Wait for a confirmation tone.
This cancels all conditional forwarding rules, including no-answer, busy, and unreachable.
FAQs about call forwarding on Sprint
Does Sprint charge for call forwarding?
Sprint (now T-Mobile) does not charge a separate fee for activating call forwarding. However, forwarded calls use your plan's minutes on legacy Sprint plans. If you are on a T-Mobile plan with unlimited talk, forwarded calls are included at no extra cost.
Can I forward calls internationally with Sprint?
Yes. Dial *72 followed by the full international number, including the country code. International forwarding rates apply based on the destination country. Check your plan details or contact T-Mobile support for specific rates.
Will my phone still ring when call forwarding is enabled?
It depends on the type. With immediate forwarding (*72), calls go straight to the forwarded number and your phone does not ring. With conditional forwarding (*73, *74, *75), your phone rings first and only forwards if you don't answer, are busy, or are unreachable.
Can I forward text messages too?
No. Call forwarding on Sprint applies to voice calls only. Text messages cannot be forwarded to another number.
How is immediate forwarding different from conditional forwarding?
Immediate forwarding sends every call directly to the destination number without ringing your phone. Conditional forwarding lets your phone ring first and only redirects the call when you can't take it, whether that's because you didn't answer, your line was busy, or your phone was off.
Can I forward calls to more than one number at once?
No. Sprint forwards calls to one destination number per forwarding type. You can set different numbers for different conditions (for example, one number for no-answer and another for busy), but each condition forwards to a single number.
