### 1/5 — BS

*2026-08-18, version 2.6.0*

After paying the monthly fee, you still have additional fees. The calls don’t ring on my phone after I setup calls to ring. This app is not worth.

### 1/5 — 3 Days imaginary Free Trial

*2026-06-16*

They claim to give you 3 days f free trial then they charge you on the spot! now is that a scam or not? you be the judge! i wouldn’t touch it if i were you

### 5/5 — Lovely

*2026-06-12, version 2.5.0*

😘

### 5/5 — Victor Williams

*2026-06-12, version 2.5.0*

Victor Williams

### 5/5 — Great for 2nd phone number or business line

*2026-06-07, version 2.5.0*

Calls actually come directly to your phone. Better than any other texting/calling app I’ve used

### 3/5 — Voicemail

*2026-03-17, version 2.3.0*

I am in the trial period and I customized my voicemail and selected it but it still plays the default voicemail version and I don’t know how to fix that. I reported the issue twice but no customer service got back to me.

### 1/5 — 10 out 10 wouldn’t recommend

*2026-03-07, version 2.3.0*

There is no 3 day trial! They immediately charge you for the $12.99 plan. We tested the app by trying to call landlines and others cell phones who were in the room. The app would ring out once or twice and then would go completely silent! The phones we were trying to call never rang. So don’t waste your time of money.

### 5/5 — Padam

*2026-03-05, version 2.2.1*

Good

### 1/5 — Total bait and switch

*2026-02-13, version 2.2.0*

Beware. This app is charging for line service and then they want you to pay 7.99 a week to lock in the number.  Plus they charge you by points

### 5/5 — Superb! Out of this world!!!

*2026-02-05, version 2.2.0*

Way above and beyond my expectations plus all the extras that are pretty compulsory in 2026 are there too!!
