Bouncer: Spam Call Blocker

From 17 October 2026, sales calls in Spain come from numbers that start with 400. Bouncer puts the 400 range on your block list, ready to use. Turn on Block your custom list in Settings, and calls from 400 numbers stop ringing.

Bouncer is a spam call blocker with no ads. Block spam calls, robocalls and unknown numbers, and let your contacts ring. A blocked call makes no ring, no vibration and no pop-up. Setup takes 30 seconds.

BLOCK 400 SALES CALLS
- Lists > Ranges already has Sales calls (400)
- Turn on Block your custom list in Settings, and every call from a 400 number is blocked
- Change it or delete it like any other range

TWO WAYS TO BLOCK SPAM CALLS
- Block spam numbers: a spam list of over 30,000 numbers, most of them Spanish, from Bouncer users and public spam lists, updated every week. Known spam and suspected spam, each on its own switch
- Block all calls except contacts: unknown numbers never ring, even new spam numbers that no list has yet

QUESTIONS

How do I block 400 calls?
Install Bouncer and make it your spam blocking app in setup. In Spain, Lists > Ranges already has Sales calls (400). Turn on Block your custom list in Settings.

Will I miss calls from my bank or my phone company?
Under the new rules, customer service calls do not come from 400 numbers, so blocking 400 leaves them alone. Your contacts always ring, and so does every number on your allow list.

How do I stop spam calls on Android?
Turn on Block spam numbers in Bouncer's settings. Numbers on the spam list stop ringing. To stop every call from a number you have not saved, turn on Block all calls except contacts.

Will the caller know they were blocked?
With silent ring, no: the caller hears ringing and may reach your voicemail. With reject, the call ends at once.

Do I need to replace my phone app?
No. Bouncer uses Android's call screening feature, so you keep your usual dialer and contacts.

Does it work without internet?
Yes. Only the spam list needs internet, for its weekly update.

Can I block other prefixes, like 902 or 905?
Yes. A range blocks every number that starts with a prefix you choose, such as +34 905 or +44 for a whole country.

NO ADS. NO ACCOUNT.
Bouncer never uploads your contacts, your allow list or your call log. Bouncer shares your block list to help find spam numbers, and you can stop sharing in Settings. Bouncer is not linked to any regulator or phone company.
