    I do think Google Voice works well for organizations that do not have a support team meant to provide regular telephone support, and instead do so on an ad hoc basis. I would not recommend it for high-volume call activities, such as SDR motions.

    I have tried other competitors. But I always end up going back to Twilio because I feel like it is dependable, easy to use, and, has competitive pricing. The only time I wouldn't recommend Twilio to someone as if they are completely inexperienced about using webhooks or APIs. Because you can't really just sign up and start using Twilio without connecting it to another platform first.

    By using WhatsApp Business, I can now respond to customers faster, keep them updated about new deals, and even send out surveys to understand their needs. The ability to send stickers and photos makes the app more interactive and engaging. It easily beats other social networks in terms of the quality and quantity of messages sent, which is a good thing for businesses.

    • UI/UX of WhatsApp has room for improvement. The goal should be to add more features for business interactions outside of the everyday messenger. (interface wise, not feature wise)
    • Multi-device use is added but it's still not as flexible and fast as other messengers like Telegram
    • File transfer is time consuming and troublesome. It also has limits.

    Google Voice has been invaluable for us in our effort to provide exceptional customer service. With Google Voice, we have been able to increase our customer interactions while reducing the wait time to reach a live person on our team. We couldn't be more pleased with the way things have worked out since implementing Google Voice.

    Unless we can get this handled quickly -- less than 1 week -- we will likely switch to another provider who, in my opinion, we'll have to spend close to $3,000 in development time to build a new integration for texting. Our clients need texting and I feel Twilio has failed us miserably.

    I think it works really well in the arena it operates in, but not so well in areas where an enterprise system would be more appropriate. It's great for quick solutions that just work, but not so much for more complex call management tasks.

    Twilio has well documented APIs and examples. There are several tutorials, videos and Q&As regarding their services. So, usability is very good. I must say that advanced knowledge of telephony, API/Programming and error-handling is essential to make good use of Twilio. It's not just plug-and-play unless you are integrated with a system that has all of the programming built for it.

    They do not offer support unless you have the Business account for Google Voice under G Suite. This is tough, because Google doesn't really have a customer support team for this service, so when it gets shut down for a few hours, we have no choice but to wait it out. But this doesn't happen that often, which is great.

    I have not had to communicate with Twilio support in the last 3 years but my past experience with them has been very positive. They replied to my previous requests promptly and kept me well informed to resolve my inquiries. With their documentation that's available, I hardly imagine why anyone would need to contact support since it's all there in a concise and easy to understand format. It would probably take you longer to type out a support ticket than to just open their doc websites.

    The integrations of Google Voice with all our devices are flawless, Android, iOS, Windows, Linux and Mac. Also, the call performance is far superior on wifi as well as on mobile data. With Skype, we had several problems with personal accounts, performance issues, and in general, it felt awkward to use it.

    We evaluated many fundraising-based text-to-give programs and found the subscriptions prohibitively expensive for our small scale and uncertain first few years of development. While we may be willing to invest that kind of money after discovering how things work, we're happy with Twilio now and have no desire to start over.

    Google Voice should be also be use to those who have difficulty in speaking English. So the contract term will need to be a little strict as Google Voice is used in navigations as the part of GPRS navigation is personal. The private data need to be in control much more securely and safely.
