    How to Buy a Twilio Number in the DACH Region How to Buy a Twilio Number in the DACH Region

    Hello and thanks for reading. By the way, this post is also available in German: Wie kaufe ich eine Twilio-Rufnummer mit Regulatory Bundles.

    If you're reading this article, you've probably heard about all the exciting things, products, and services you can build with a Twilio number. You can send and receive SMS, receive calls, design an Interactive Voice Response (IVR), and code any telecom scenario you can think of in your favorite language. And it all starts with a Twilio phone number.

    But, unfortunately, it is sometimes not so easy to purchase a number. We developers are often unaware that national regulations determine who is allowed to acquire a telephone number and under what conditions.

    Many legislators prefer this approach because it helps prevent abuse and spam. However, it can be a challenge for us, as some legislators are stricter, while others are more relaxed, allowing easier access …

    Send Bulk SMS With Go and Twilio Send Bulk SMS  With Go and Twilio

    Sometimes, nothing beats a good old SMS. The delivery of an SMS is not reliant on the recipient having any form of connection to the internet. This makes it highly reliable when delivering critical notifications. In certain instances, such as Amber alerts, for example, these notifications need to be sent in bulk to a wide audience.

    You might be wondering how difficult it would be to implement such a system. Well, with Twilio it’s actually a breeze. In this post, I will show you how to build a bulk SMS-sending application using Golang, powered by Twilio.


    To follow this tutorial, you will need the following:

    The first thing you need to do is to create a project directory and change …

    How to embed Twilio Conversations in a Retool app for bidirectional messaging Embed Twilio Conversations in Retool for bidirectional messaging

    Twilio Conversations makes it easy to add messaging to your applications using Twilio's SDKs and APIs. But presenting a chat dialogue in your product or on your website is only half of the battle. You also need to build a chat interface for your agents to interact with.

    In this tutorial, you’ll use the Twilio Conversations JS SDK to add bidirectional messaging capabilities to an agent portal built in Retool. Retool is a development platform for internal tools. Together, Twilio Conversations and Retool provide a powerful and easy-to-use toolkit to build custom chat-enabled internal applications.

    A user interface screenshot showing an in-progress chat conversation between a customer and an agent. SMS settings are displayed on the left, a chat window is displayed in the middle, and an emoji picker is displayed on the right.

    How to Test Your Twilio App from India Using Twilio Dev Phone Test Your Twilio App from India with Dev Phone

    There are few things more frustrating than sending a test message or call to your application and not getting through – especially if you check the Twilio logs and see that your call or message never reached the number. If you’re a developer in India, your development process might be running up against some special telephony restrictions.

    It is important to understand India’s messaging limitations before you consider developing an app to send SMS to Indian mobile devices. However, if you just need to test an application that is being developed for deployment in other countries, the Twilio Dev Phone is a great solution.

    Limitations of Twilio SMS to Indian mobile devices

    When sending messages to India from Twilio, your Twilio phone number won’t appear as the sender of the message: the sender ID will be changed by the carrier before your SMS messages are delivered to end users. Usually …

    How to Build ADHD Lifehack Tools with Python, Google Sheets, and Twilio SMS How to Build ADHD Lifehack Tools with Python, Google Sheets, and Twilio SMS

    I can say from experience that ADHD adds several layers of complexity to life on an already chaotic and distracting planet, and while we need all the help we can get, it’s often difficult to find tools that you stay in the habit of using and that actually help.

    By building your own, not only will you be able to have a tool built custom for your brain, but the satisfaction of building something may encourage you to keep using and optimizing it!

    In this tutorial, we'll be building three helpful tools:

    • An SMS task-inbox-and-notetaking app
    • A die roll app for moments of indecision
    • A timer that texts you when time is up

    The theme of the project examples in this post are all about getting things out of your head, and getting yourself out of your own head, two very common challenges for ADHD brains.

    How will these apps …
