The "magical" DIY (Do It Yourself) communication system

After 2 years using Twilio services, mainly phone and messages, I can say I am so happy I found this solution to handle my communications. It is so flexible, Although it has been a little bit complicated sometimes to self-learn about online phoning systems it saved me from a lot of hassles I wanted to avoid. The best benefit you get is the ultra efficient support service

Pros

With Twilio you can start from scratch to build your own online communication system. I didn't know so much about VOIP before and it is true I had to learn a few things. So far I have been able to use my Twilio french mobile number fully online even whenI need to travel abroad - with all mobile services you can expect (voice, SMS, MMS). The pricing is light and the global user interface makes the whole systme pretty easy to manage. I only use a few features from the platform but the possibilities are huge ! And they are always working on new services. And as Twilio is now really recognized as a communication company you can find additional software apps very easily and even documentation, I am thinking of the softphone app I am using on my mobile or desktop for instance.

Cons

I could customize a personal solution because I had time to test different options and as a developer I could code stuffs if needed. I am not sure everybody can do the same without technical skills.

Outstanding Platform for Businesses Using WhatsApp

Overall it has been positive so far. We are launching our software globally now and so far they have been a solid partner in the countries we have been going to.

Pros

We used Twilio to be the backbone of custom cross-platform messaging software we built that connects people in different countries around the globe. We used it to send automated messages alerting the users that someone in their area wants to talk to them and then to continue to facilitate the conversations through our software and the WhatsApp API protecting the user's identities. The API was very easy to use. The hardest and most challenging part was getting set up and approved by Facebook to get our WhatsApp numbers. The system tracks if messages were delivered which is great and we can see responses come back in as well, not the message content itself mind you, but that a response was sent. We also leverage their email platform which added another communication platform to our system. All in all, we are excited about our partnership with Twilio and look forward to continuing to work with them.

Cons

The only challenging issues we had really involved WhatsApp and getting them to verify our Facebook Business listing, then approve us for a WhatsApp number and finally approve our message templates so we could use Twilio to send messages through their platform. I wouldn't say any of that was Twilio's fault and their staff was excellent at doing everything they could to help us. The only thing I would like to see is a better more laid out navigation on their admin dashboards. You have to click into menus to get to a sub menu to then scroll around and try to find what you are looking for. It would be nice if they had a master link tree like Amazon does on their AWS dashboard.

Tyranny of the 2FA gods!

Authy by Twilio is a run-of-the-mill 2FA app. There's nothing special about it. It works when you're not switching your hardware.

Cons

Customer Support is only available by email, not by phone, and it takes 1-3 days to hear back from them. I was in the process of integrating their OneTouch functionality into a software program I'm designing, and I finally found out why no one else integrates it. It's busted and when you go to click the "Accept" or "Reject" buttons, it gives you an error. Authy support said to reinstall my Authy app, and now I can't get back into the app until 2 days later because of their overbearing security. They refuse to get me out of the bind, and I'm unable to access any of my accounts until they lift the hold. I've learned my lesson and I'm going to use LastPass so they can't hold my accounts hostage anymore for their nefarious purposes.

Twilio also has a couple of secret super powers!

An amazingly well built product -- we rarely if ever had reliability issues -- the Twilio Functions were an especially useful post-purchase feature discovery -- so much so that we still use that even though we don't do any texting. We also sometimes use FracTEL, since they beat Twilio on pricing 3:1 for 1-800 texts *and* had MMS 1-800 support long before Twilio.

Pros

* super easy to configure multiple accounts for billing purposes * * Twimlets are a great way to experiment with product &/or prototype quickly - https://www.twilio.com/labs/twimlets * Twilio functions is amazingly easy way to either extend power of tools such as Zapier &/or avoid having to use AWS Lambda, etc. -- it's a super cool hidden feature - https://www.twilio.com/docs/runtime/functions * They have an auto-stop feature if you accidentally send too fast -- e.g., we accidentally created an infinite loop of texts between two phone numbers -- which they auto-stopped at about $20 (in three minutes). There are likely other Twilio features hiding in plain sight -- poke around -- one of those rare cases where reading all the documentation is likely worth it

Cons

* the login process can be annoying * help sometime takes longer than 24 hours * configuring multiple sub-accounts is confusing at first * not all functions can be done via UX -- some require API calls -- curl scripts were our goto

Still stuck on a WhatsApp integration because facebook won't authorize a company's facebook page despite sharing the company legal forms/requirements. The whole process was smooth until we had to come to a stand still because of this. Would be great if some of this pain is either waived or taken care of since we had a paid Twilio number already.

Pros

Documentation is well presented with a very generous trial period and account. This offers ample build time and usability period to run proper production simulation before purchasing the commercial product.

Cons

Most of the requirements by Twilio are based on third parties' compliance and response. It would be great if Twilio took lead on some of these if possible, represent or sale this representation so that the client doesn't need to go back and forth to meet various third party requirements. One stop center for a complete solution!

Reasons for Choosing Twilio Voice API

Wide coverage and ease of integration.
