We'll focus on making as many changes backwards compatible as possible so that you, ideally, are not required to do any additional work or change your code. We are still working on defining the final process on the Twilio side with the goal to abstract away most, if not all, of the complexity of A2P 10DLC as long as you send fewer than 3000 SMS segments and MMS messages per day with 5 or less local phone numbers. While we partnered with carriers to find a solution that works for the entire messaging ecosystem, Twilio continues to focus on simplifying the process for our customers. Additional numbers can still be used for Programmable Voice or to text to Canada or internationally. You can keep more phone numbers but you will only be able to use five US local phone numbers to send SMS to US recipients. What if I have more US phone numbers in my Twilio account? You can reduce such errors by registering your business profile as explained above. If you reach your daily cap you'll receive a dedicated 30023 error code from Twilio and you should only resume sending messages the next day. In order to send more messages than your 3000 per day, you'll have to register a Business Profile in our Trust Hub and create a Messaging Service with the appropriate Campaign Use Case. If you can’t find your answer, head over to our dedicated A2P 10DLC page and request to talk to an expert. You can find the most common questions we get from developers below. You might have a lot of questions about these changes and we are here to help you. Today we are excited to announce the outcome of these changes. Over the last six months we've been working with our partners at T-Mobile and AT&T to create a verified SMS ecosystem that remains accessible for builders/developers while increasing trust and reducing fraud. Since day one of Twilio, we’ve focused on making sure telecommunications is as accessible as possible for developers to create everything from garage door openers, to wedding invitations over SMS, or even businesses built entirely on SMS. However, some of these changes are hard (or even impossible) to understand and follow for developers and very small businesses, and we heard your concerns and are here to help. A2P 10DLC brings along a variety of changes including registration changes, carrier fees and daily caps. In this blog post we'll discuss how these changes impact developers and small businesses using Twilio to send SMS and what Twilio did to address your concerns. If you haven't heard about A2P 10DLC yet, head over to this blog post to learn more. We will provide another update in 24 hours or as soon as more information becomes available.If you send programmatic SMS in the United States, you might have heard about the current plans by AT&T and T-Mobile to create a more trusted SMS ecosystem through A2P 10DLC. This process may need to be repeated until a long term fix is released. This process will remove and re-apply the international roaming permission for 1 MONTH from when the update finished. Once the update is finished, move the SIM back to the original Rate Plan with international roaming enabled. Our downstream connectivity partner’s has a release tentatively planned for September 22.Īs a workaround, while we continue to investigate the root cause and long term remedy, if a Programmable Wireless SIM outside of the US loses connectivity, you can move the SIM to a Rate Plan with international roaming disabled. We expect that they will need to make changes to their provisioning platform to fix the issue. We continue to investigate the issue with our downstream connectivity partner. This results in devices being blocked from establishing data sessions after the permission expires. Our downstream connectivity partner believes the root cause of the issue is that international (non-US) roaming permissions that should be automatically renewing each month are not. Since then, we have discovered new information about the incident and that all SIMs outside of the US may be at risk of losing connectivity. A previous incident related to this issue was opened on August 10. Since August 5, Programmable Wireless SIM’s outside the US may unexpectedly lose connectivity.
