858 number questions

What if 858 numbers are sold out?

Popular area codes run out from time to time, and numbers come back as others are released. This page shows the stock live, and 619 cover the same area.

How much does a 858 number cost?

Will a 858 number receive verification codes?

Some apps and banks refuse VoIP numbers for sign-up codes. For those, use SMS Verification, which gives you real mobile (non-VoIP) numbers.

Do I need an app or a SIM card?

No. Calls and texts work in any modern browser on a computer or phone. Allow microphone access once and you can make and take calls.

Can I call emergency services?

No. Smart Dialer can't be used to call emergency services such as 911, so keep another phone for emergencies.

How do I pay?

Add credit to your balance with crypto (USDT or USDC on Solana or Ethereum) from the Billing page, from $5 a time, then every service is paid from that one balance. There are no long contracts: you only pay for what you choose.
