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. What good is a second phone number if it’s plagued by spam calls and texts? 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 9pm 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. If you need a different number later, no problem – you can switch.

The number one take away from competitor reviews is that customers get spam calls and texts on their new phone numbers, just like their personal numbers. 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. You don’t want a burner number, you want a second 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.


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


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


Make and receive as many calls and texts (US & Canada) you need to in order to get work done. Run your business with a flat-rate subscription and don’t worry about overages.


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. We promise to never sell your data, spam you, or waste your time.

Great App, Fantastic Support!

Just got off trial and found the app to be intuitive and easy to use. Integrates all call and text information between lines so there’s no confusion where calls are coming from. Had initial setup issue with my carrier and support team was on the spot getting it corrected. Communicative, responsive and very friendly.

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.

Middle of the Road Solution

I enjoy the clean UI, list of available numbers, and ability to set business (do-not-disturb) hours. However, from what I can tell, there is no way in the app or thru Apple Subscriptions to switch between monthly / annually subscriptions. I would likely give this app one more month prior to deleting it, unless I am able to upgrade to an annual subscription. Personally, I dislike the idea of a monthly recurring charge for app subscriptions.

Hi Muay Thai Warrior,

We just rolled out an Annual subscription offer! Please have a look at SwitchUp's subscription options and you should see the new option. This support article should provide you with some additional help https://support.apple.com/en-us/HT204939.

We hope you find this change a reason to increase your review to 5-stars, it would mean a lot to the small team. If you have any more feedback, please reach out via support in the app under Settings>Support and the icon in the top right hand corner.
