Why use a local Singapore number?

In Singapore, phone-first onboarding is the norm: PayNow and Carousell both ask for a mobile number before anything else. Geo-matched numbers keep your QA runs realistic and your conversion tests honest.

Tips for Singapore verifications

Format: +65 8XXX XXXX or 9XXX XXXX. Paste the number exactly as shown — OTP Bolt already includes the +65 prefix.
Language: most Singapore services send codes in English; the inbox shows the full SMS text so you can read context, not just digits.
When a code doesn't show within two minutes, cancel and rent another number; you're only charged when an SMS actually arrives.
Running automated tests? Call the OTP Bolt REST API with country="sg" and poll the activation until status is "received".

Frequently asked questions

How fast does a Singapore OTP arrive?

Most +65 codes land in 5–40 seconds. The OTP Bolt inbox polls the carrier continuously, so you see the SMS without refreshing.

What if no SMS comes to my Singapore number?

If the rental window closes without a message, the full price returns to your wallet automatically. You can also cancel early once the network allows it.

Can I keep a Singapore number long term?

Instant-OTP numbers are single-use. For a number you keep, see My Numbers — dedicated US and Canada lines with an SMS inbox and browser calling, billed on flat terms.

Is it legal to use a temporary Singapore number?

Receiving an SMS on a rented number is legal in most places, but every app has its own terms. Use OTP Bolt for testing, privacy and legitimate signups only.
