Call forwarding sends the calls that come to your Boost Mobile number on to another number. The codes below are the ones our setup page gives Boost customers: one to forward every call, and one to turn that off again.
The code to dial
| What it does | Dial |
|---|---|
| Forward every call to another number. | **21*NUMBER# |
| Turn that forwarding off. | ##21# |
Replace NUMBER with the 10-digit number you want calls to go to. Dial it from the phone's keypad as if you were calling someone, press call, and listen for the short confirmation tone.
On an iPhone
If your iPhone has a Call Forwarding option, it's at Settings › Apps › Phone › Call Forwarding. Turn it on, tap Forward To, enter the number and tap Back. Apple documents this switch for service on a GSM network and tells everyone else to contact their carrier. You also need cellular signal while you set it. The other route is the Phone app: tap Keypad and dial the code from the table.
On an iPhone with two lines, pick your Boost line before you tap Forward To. While forwarding is on, a small Call Forwarding icon sits in the status bar, so you can tell at a glance whether it's still set.
Apple warns about one trap. iPhone blocks links in texts, emails, webpages and apps that ask you to turn call forwarding on, because scammers send them. Type the code yourself or use Settings.
On a Samsung or another Android phone
Galaxy phones: Phone app › More options (three dots) › Settings › Supplementary services › Call forwarding. Choose Always forward to send every call, or Forward when busy, Forward when unanswered or Forward when unreachable for the conditional kinds, then enter the number and tap Enable. Samsung says the options depend on your carrier and phone model.
On a Pixel, a Motorola or another Android phone, dial the code from the Phone app's keypad.
Turning Boost forwarding off
Dial ##21# from the phone, the off code our setup page lists. If you turned forwarding on in the iPhone's Settings or on the Samsung screen, go back to the same place and switch it off there.
Checking that it took
Call your Boost number from a different phone. With forward-all on, the call should go to the number you set, and your own phone shouldn't ring. If your phone rings as usual, the code didn't register. Dial it again, check each digit of the number, and wait for the confirmation tone before you hang up.
If the code doesn't work on Boost
Start with Boost's own steps for a phone that isn't making or getting calls: check that the number isn't blocked, turn mobile data off for a minute and back on, and reset network settings (on an iPhone, Settings › General › Transfer or Reset iPhone › Reset Network Settings). If calls still misbehave, Boost's help center says to contact Boost Customer Care.
Some prepaid and MVNO plans don't support call forwarding at all. If you've signed up for VettedCalls and your carrier can't forward your calls, we refund everything you paid, as long as it's within your first 14 days.
For the no-answer, busy and unreachable codes that other carriers publish, see conditional call forwarding by carrier.
Forwarding a Boost line to VettedCalls
In setup Step 4 you pick Boost Mobile, dial **21*NUMBER# with your VettedCalls number in place of NUMBER, press the call button and wait for the short confirmation tone. Every call to your Boost number then comes to us first, and your cell shouldn't ring by itself. We ask new callers who's calling and why, and the calls that pass ring you in the Cloud Softphone app. Your saved contacts, and callers who passed screening in the last 60 days, skip the questions, though their calls still come through us. ##21# turns forwarding back off. Start setup.
