650 number questions

Can I pick my own 650 number?

Yes. You see the 650 numbers in stock and pick the one you like. It stays yours for as long as it renews.

What if 650 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 415, 628 cover the same area.

How much does a 650 number cost?

Pay as you go from the monthly price shown above, or pick a plan with incoming texts and minutes included (unused ones roll over). The carrier's one-time activation fee is passed on as is. Outgoing calls to US numbers are 0.6¢ a minute and texts within the US and Canada 1¢ each, from your balance.

Will a 650 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.
