## レビュー

### "Convenient" — 3.0/5

> **Pamela** | *2018年3月29日* | アウトソーシング、オフショア | おすすめ評価：7.0/10
> 
> **良いポイント**: Sideline works as a separate line on my phone. I use it as my business mobile number.
> 
> **改善点**: The name doesn't appear 99% of the time (only the number), even though the caller is listed in my contacts. Calls are not always clear. Doesn't have as many features as other competitors and less than TextFree, the free service offered through Pinger (Sideline's parent company). I have always paid for the service. Customer service is not the greatest.

### "Great service to ditch the landline" — 5.0/5

> **Ross** | *2021年8月9日* | 健康、ウェルネス、フィットネス | おすすめ評価：10.0/10
> 
> **良いポイント**: I was able to stop using a landline and add it to my cell phone. I have my office phone with me at all times now and can manage when it is answered and set to away etc.  Along with being 1/8th the price of the landline I can also text directly with people instead of using my personal number or a service.
> 
> **改善点**: There really haven't been any con's to the software.  I think I have had a total of 3 calls that were of unacceptable quality in more than 3 years of use, and I cannot even guarantee that the poor quality of the call was because of sideline.
> 
> Great product that does exactly what it says it will. &#10;I also love the voice to text options, the ability to text from it. &#10;The ability to set multiple away messages and switch them easily is also quite useful.

### "Poor Support and Functionality. Best for small teams less than 10 people" — 2.0/5

> **Chris** | *2025年6月3日* | 人材 | おすすめ評価：3.0/10
> 
> **良いポイント**: This is very simple setup that is good if you are just one user and that is it. They recently are removing the enterprise option but this is what we used. Super simple setup though, no TCR application or managing anything just works.
> 
> **改善点**: Support is very lackluster, you cannot call anyone. All support is handled through the chat. &#10;&#10;Randomly and without warning, your account may be blocked due to them thinking you are spam and you are not notified. Meaning that you do not know for how long you were blocked for having to double check with clients. &#10;&#10;Does not support features like transferrring, recording or even downloading any voicemails.
> 
> I would say that overall I was very unimpressed with sideline. Having to support a team of about 15 users there was always issues. I also remember during November 2024 we received an alert that our service would be disruptive during the use in the presidential campaign.

### "Great tool for collectors" — 5.0/5

> **Angela** | *2020年4月9日* | 金融サービス | おすすめ評価：9.0/10
> 
> **良いポイント**: It gives you the ability to have an extra phone number to use while collections. It has all the capabilities as any other phone number, text mssgs, voice mssgs.
> 
> **改善点**: The increased the cost of the subscription. Other than that the product is great and offers great features for the price.
> 
> It provides another option to reach those customers that already have your phone number blocked. Get more ways of communicating with difficult customers. Less expensive than a regular cellphone line.

### "Great product at a great price\!" — 5.0/5

> **Mark** | *2025年4月25日* | エンタテインメント | おすすめ評価：9.0/10
> 
> **良いポイント**: I'm able to text on my business line, and the price is excellent.
> 
> **改善点**: The call quality is sometimes not excellent. The number porting took some time.
> 
> It's an affordable, quality product for people and businesses that want to transfer or have a new phone number. You have a rich array of features to manage your phone calls. You can also use a desktop version.
