Works for what I need.  Rayj97401  3 star

Voice quality poor. Connection drops much more frequently than Line1. Has several nice features like voice mail to my email. Still learning about the features. Costs $25 for a set up phone conference.

Thinks local numbers are international numbers and wants you to pay.

It works  Seanbrero  4 star

I was needing to turn my iPod touch into a phone. This app did the job. I subscribed for the $10 monthly fee. I'm able to call and text with wifi. The settings are quite bareboned. Besides that, I'm happy

Excellent.  SteveKCAloha  5 star

Comprehensive and easy to use. Love it.


Does anyone else have this problem???  Bob775  2 star

As one person stated in a previous review sometimes the app doesn't ring and either shows a missed call or you get a voice mail. Doesn't happen a lot but it does happen. 2nd thing is since the last update when I use a Bluetooth headset and while I'm on a phone call a 2nd call comes in it makes the first phone call garbled so then you have to disconnect and call people back. So I have reported it but nothing has been done I have had to forward all my phone calls to my cell phone. I can make a phone call out on Line2 but receiving a call and the getting a second call is impossible. I get a lot of calls in day so it is a big deal to me. Other than these problems it works great love it. So when Line2 gets this fixed I will then rate it 5 stars.

Fix Drop Calls

Line 2  Fix Drop Calls  2 star

I use this as a second line for business on iPhone 6. The drop calls occur about every other call or less. It's great to have this second line to screen business calls. Any help with drop calls is appreciated...

Unstable Service  Nice Tech Guy  2 star

I've had this service and it's hit or miss on how the call quality is. I keep it as a 'junk' number to give out to companies that I do not want having my true number like catalogs, online ordering , take out food etc. so it works fine for that. I did try it for a month as a business line but the line quality was just too poor and unacceptable to me.


Great App!  aoKane7  5 star

I love being able to take business calls anywhere in the world with no issues.


Perfect!!!  ZuckeyLA  5 star

I have been a long time client of Line2. We have the Pro account with 3 lines. They only keep getting better. Call quality is excellent. Customer service and support is the best in the business. Now that their system accepts SMS short codes there is no "second line" company that comes close. I don't normally write reviews but when short codes began working I had to write this.


Bye Bye AT&T!  ScreamnNav  5 star

I love this service. It does everything it says it does and using it on my cell as a second line is easy! I cancelled my second AT&T line and I'm saving $50 a month and only carry around one phone!


I really like this app  888elsine  5 star

I'm a psychologist and this is a very useful app for me. It allows me to separate my personal cell phone from my business line.
