A2P 10DLC Campaign Vetting Delays: We are experiencing delays while vetting 10DLC campaigns. Our third party is reviewing campaigns manually, and due to the high volume of requests, a queue has built up. Campaign reviews are expected to take longer. Twilio is working with the provider to help expedite this process. New details will be shared in our incident report as soon they become available.

Unicode messages are being split on recipient devices


When using the deprecated SMS/Messages resource URI to send text messages, messages with one or more non-GSM characters are limited to 70 characters. Any SMS messages that include 1 or more non-GSM characters will be separated by Twilio into messages of 70 characters or less on the recipient's device. However, Twilio will not create separate messages with unique message SIDs in your Twilio SMS logs. In your Twilio SMS logs you will still see the message as one message SID.

You can find out what characters are included in the GSM set here. You can also paste the text you're attempting to send into our Message Segment Calculator to verify your messages are free of non-GSM characters.

If you are sending unicode messages to mobile numbers in US and Canada, try the Messages Resource URI instead. With this updated URI, you can send messages containing up to 1,600 characters without being split on the recipient device. However, please also note that behind the scenes, SMS carriers still handle messages in "segments" regardless of the URI used, and SMS are billed per segment (This does not apply to MMS). The recipient should still see these as a single concatenated message using the new URI."
