Guidelines

Two-way SMS supported	No

Message length	160 Characters
Twilio MMS support	Converted to SMS with embedded URL
Sending SMS to landline numbers	You cannot send SMS to a landline destination number: the Twilio REST API will throw a 400 response with error code 21614, the message will not appear in the logs, and the account will not be charged.
Compliance considerations	Carriers in the United Arab Emirates are heavily filtering SMS traffic, so Twilio recommends pre-registering an Alphanumeric Sender ID to improve delivery. Unregistered Sender IDs will be replaced with generic Alphanumeric Sender IDs and may be blocked by carriers. All promotional Alphanumeric Sender IDs must carry an `AD-` prefix, and this counts towards the 11-character limit. Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to make sure that they comply with all applicable laws. The following are some general best practices: Get opt-in consent from each end-user before sending any communication to them, particularly for marketing or other non-essential communications. Only communicate during an end-user’s daytime hours unless it is urgent. SMS campaigns should support HELP/STOP messages, and similar messages, in the end-user’s local language. Do not contact end-users on do-not-call or do-not-disturb registries.
