Head to head

Which one is right for you?

Every one of these apps is a reasonable pick for someone. Here's when each makes sense.

SideNumber vs Google Voice

Google Voice is free, and if you only need one US number for personal calls, it's hard to beat on price. The catches: the free plan is for personal use only, you need a Google account and an existing US number to sign up, and you get one number per account. See the full breakdown.

Google Voice fits if

  • You want a free number for personal use and one is enough
  • You already have a US number and live in Google's apps

SideNumber fits if

  • You're selling, renting or running a side business
  • You want more than one number, or a Canadian one
  • You don't have a US number to verify with, or you're on a Wi-Fi-only tablet
  • You'd rather keep the line out of your Google account

SideNumber vs Hushed

Hushed covers more countries, which matters if you need a number outside North America. SideNumber keeps it simple for US and Canadian numbers: flat monthly or weekly pricing with unlimited calls and texts, and bundles that bring the cost down as you add lines.

Hushed fits if

  • You need a number in the UK or another country outside the US and Canada

SideNumber fits if

  • You want one flat price with unlimited calls, texts and picture messages
  • You're running 3 or 10 lines and want bundle pricing

SideNumber vs Burner

Burner and SideNumber are the closest match. Both give you US and Canadian numbers you can hand out and drop when you're done. The difference is in the extras: SideNumber adds Voice Changer for live calls and bundle pricing that works out to $6 a number when you run ten lines.

Burner fits if

  • You're already set up on Burner and happy with it

SideNumber fits if

  • You want Voice Changer on calls
  • You want several numbers under one subscription
  • You want sign-up with no verification step
