Recent update...  dj kwireboi  5 star

Recent update has very spotty connection, and my airpods act very weird now. They keep disconnecting, and if I’m playing music on Spotify before I make a call, it doesn’t resume playing when I hang up and I have to reconnect the air pods. It worked perfectly before this update. UPDATE: fixed! Thank you!


support is terrible, calls and texts don't come through  Shaniez  1 star

I use this for my business. After they became a paid service, things were rocky for awhile. They had improved, but recently the app has been terrible again. The caller ID rarely shows the contact information for my saved contacts (it just shows the phone number), the app freezes every time I open it, I don't get notifications for calls or texts, and there are texts that just don't come through.

Was great until recently  Jose the conquer  1 star

This app was great until the caller ID stopped linking with my contacts so I would just see the phone number that was calling in. I contacted the support email and was given instructions on how to possibly fix it. The fix made the problem worse and now my contacts are being filled with duplicate sideline numbers, and I no longer even see the numbers calling me. The support email has informed me engineers are working on this issue but there is no ETA on resolution. It’s disappointing the support I received made the issue worse with no additional suggestions for fixing the issue. Not what I would hope for from the most expense app I’ve ever paid for.


Very Bad 2nd phone number App  Jetdizzle  1 star

This service was initially free and then I paid for a $2.99 version for more options and then they increased it to $9.99/mo or $99/yr and I paid for that. During this time I spent thousands of dollars advertising, having business cards made, posters, banners, and large advertisements/prints, etc. with my number I used and paid for with Sideline. After a few months use of calling business clients and new customers back with few people answering the phone and most often unanswered calls, people hanging up b/f I could speak and blocked calls, I asked a good well known business partner what number is showing up to them when I call them with my business / Sideline number. I was stunned to find out they were receiving random phone numbers when I used my Sideline Phone Number! I did more research and found out that the reason a lot of current and new customers did not answer or reply to my phone calls was because they were receiving random out of state phone numbers on their caller ID’s and not my personal business number I was told I had when buying this app. Sidelines App has cost me countless hours of time, new and existing customers, lost revenue, and all the $$$$ invested in business cards, flyers, banners and signs with my number that was being Re-routed as as a different number to customers caller ID’s on there phone and many customers numbers I had saved said they thought it was spam / telemarketers when I would call due to it always being a random out of state area code / phone number they would receive when I called them. Unbelievable what Sideline did to me and my business. Additionally, they want to charge me more money to have my number available for me to use with a more reliable and professional business number app or service carrier. DONT FALL FOR THIS TRAP OF DECEPTION. I RARELY leave bad reviews and tend to review businesses that are really good, but I felt the need to spend the time on this review as I feel that it would be wrong not to help give other businesses the information about Sidelines shady tactics, deception, and false information Sideline gave me.


Great app👍🏻👏🙌🏻  sgq101  5 star

Its like having two carriers on one phone, auto reply feature is great.


Best way to add second line needs better anti-spam  Kb2jpd  5 star

Been using it for several months. Absolutely flawless and never a crash. Buy it if you need it. Transfer of old number was quick and flawless , again. If you could please, improve the Spam and AntiRobocall capability. Some of us have a contact called Spam or Suspected Spam which we then block. Add the ability to use the Spam contact in Sideline to fight all the robocalling prone today. The individual blocking feature is useless of you have 75 incoming robocalls a day. Who wants to individually block each one? How about a Select All feature to block all those robocalls? Keep us the good work.


Contact list sorting  e320us  1 star

Despite multiple requests over the past two years, the app still sorts the contact list by last name.
