Get a second phone number in less than 3 minutes with SwitchUp! SwitchUp is the first second-phone-line app designed from the ground up with spam protection and your privacy in mind. SwitchUp’s spam blocking is powered by RoboKiller - the leading spam call blocking app with over 11 million downloads!

Do you have your own business or side hustle and need to answer every call, except the ones after 9 pm on a Friday night? Need a second number to give out to websites? Are you a freelancer who needs a second phone line but not the hassle of a second phone? Then it’s time for SwitchUp.

Choose from THOUSANDS of local phone numbers and get the perfect “SwitchLine” as your second phone number. Own the second phone number, not rent it! If you need a different number later, no problem – you can switch.

Other apps might offer you highly recycled numbers that work for a few weeks before the spam problem gets so bad that you need to get another number.

What good is a second phone number if it doubles the number of spam and robocalls you’re bombarded with? Your new number is protected 24/7/365 with the best spam blocking technology - no additional setup required.

Make and receive as many calls and texts (US, Canada, and Puerto Rico) you need to in order to get work done. Communicate one on one or in chats. Run your business with a flat-rate subscription and don’t worry about overages.

SwitchUp makes it easy to customize business hours for each day, allowing you to disconnect on your terms.

Silence SwitchUp calls and texts for a custom time so you can have a rest or get your work done, undisturbed.

Don’t have the time or ability to answer every call and text? Set up an automatic text reply.

Accidentally read a new message, want to save a message for later, or don't want to read it at all? Mark it as Read or Unread.

SwitchUp is powered by RoboKiller which has been featured on The New York Times, NBC, Wired, Engadget, Vice, and other publications.

SwitchUp is built by people who hate robocalls, spam texts, and respect your privacy.

All my contacts are initially blocked

I love every this app does, but I have to unblock each contact I’ve added the first time they contact me instead of automatically. If there’s a way to fix this please let me know. They don’t receive the auto text replies until they are unblocked and I’d prefer to not have to ask everyone to text me now to make that happen as this is for my business. Please explain how to do this.

The problem never resolved and dropped

Contacting customer service is like sending messages to Mars. Purchased the app for use as a business number. I had friends that used different cell phone carriers call me. The phone does not allow for calls to come through from AT&T customers. That is great right. A lot of my business comes in from Instagram.
I removed app put app back on phone twice. I did everything that customer service suggested could be the problem. Everything they suggested that I didn't do with their app I had already done.
So now I have 300 garment labels printed with my business phone number that doesn't accept phone calls from all carriers.
You also have to wait for days for them to actually address your email. So now I am stuck and their free one month is a joke because your issues are not worked out in a month however you are billed on time. I went with them because I thought they were vetted by Apple. Go with Google it is free.

A joke

We use this app for our business, but have been having issues where we can’t even use it AT ALL. Trying to contact someone to help is IMPOSSIBLE. And when they finally decide to reach back out all they have to say is they are aware of their problems. Excuse me? We are a business we cannot afford to have that lame excuse while we are possibly losing business. And if you are aware of your problem how about you reimburse your customer or even contact them to answer their questions. Terrible company terrible idea. I would have anyone who uses this as a means of important communication to reconsider as it might not even work and to pay for something that doesn’t work is a cheat of your money.
