Guidelines
Two-way SMS supported Whether Twilio supports two-way SMS in the given locale.	No
Number portability available Whether number portability is available in the given locale.	Yes
Twilio concatenated message support Concatenation refers to the capability of splitting a message that is too long to be sent in one SMS into smaller pieces and then joining the pieces at the receiving end so that the receiver sees the message as one.	Yes* For certain sender ID types this may not be supported. Where messages are split and rejoined may vary based on character encoding.
Message length How many characters can be sent given a particular message encoding before the message will be split into concatenated segments.	160 characters
Twilio MMS support Multimedia Messaging Service (MMS) provides a standards-based means to send pictures and video to mobile phones.	Converted to SMS with embedded URL
Sending SMS to landline numbers How Twilio handles an SMS message destined for landline telephone number.	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 Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to make sure that they comply with all applicable laws. This table lists some general best practices.	Because Turkish carriers filter traffic with Numeric and unregistered Alphanumeric Sender IDs, be sure to pre-register your Alphanumeric Sender ID to ensure message delivery. Person-to-person (P2P) traffic, as well as content related to gambling, politics, and religion are prohibited. From February 15, 2021 — and until further notice — submission of promotional traffic to Turkey will be prohibited. Please do not submit such traffic as it may result in your messages and your registered Sender ID being blocked. It may also result in financial penalties. Message delivery to M2M numbers is on best-effort basis only.
