What does Second Number do?
Second Number rents out virtual phone numbers so you can receive the SMS and OTP codes that sites and apps send when you sign up or log in. According to Second Number, numbers are available in more than 180 countries, and you pay only for the SMS you actually receive rather than for a number you leave sitting idle.
Their site describes two ways to use it:
- Short-term numbers for a single verification code
- Long-term rental of a number you keep, so the same account can receive codes again later
They also list an API for people who want to order numbers from their own tools instead of the website.
Who it is for
- People who run several accounts on messaging, social or marketplace platforms and need a separate number for each verification
- Teams that automate account setup and want to order numbers through an API
- Anyone who would rather pay per received code than hold a SIM for every account
What we have and have not checked
We haven’t bought a number from Second Number or tested whether the codes arrive reliably for any particular service. Everything above comes from Second Number’s own website and the details they sent us.
Platforms differ in whether they accept virtual numbers at all, so check that your target service takes them before you rely on one. This is a listing swap: no money changed hands, and we don’t earn commission on the link above.
Why pair it with Singapore Mobile Proxy
A phone number is only half of what a platform looks at when you register an account. The other half is the network the sign-up comes from. A new account that verifies with a number from one country while connecting from a datacenter IP in another is an easy mismatch for a risk system to flag.
If the accounts you are registering are meant to look like Singapore users, a Singapore Mobile Proxy port gives each one its own exit on a physical Singtel, M1 or StarHub SIM in a modem here in Singapore, with real Singapore geolocation. The sign-up then comes from the same kind of IP an ordinary phone user sits behind.
The honest limit: we cover one country on purpose. Second Number’s numbers span 180+ countries, so if you need the connection to match a number from somewhere other than Singapore, we are not the right proxy for that account, and you will want a provider in that country.
Setup
Any browser, anti-detect profile or automation tool that accepts a standard HTTP or SOCKS5 proxy will work. Add the host, port, username and password from your dashboard to the profile you register the account in, check the exit IP, and then request your verification code.
A free trial port is available if you want to confirm it is a real Singapore carrier line before you spend anything.
