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.

Message delivery to M2M numbers is on best effort basis only.

Dynamic Alphanumeric Sender IDs are supported. However, non-Polish Numeric Sender IDs to some networks in Poland will be overwritten to an Alphanumeric Sender ID to ensure delivery.

The use of URL shorteners such as bit.ly or tiny.url is strictly prohibited in Poland. Use the full form of the URL instead. Moreover, if you need to include a full URL in the content of a Long SMS (more than 160 characters), we advise you to test it before submitting a large number of messages as the local networks tend to block this type of message. Contact Twilio support with the exact text you would like to send, if you would like us to perform this check for you.

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:

1. Get opt-in consent from each end-user before sending any communication to them, particularly for marketing or other non-essential communications.
2. Only communicate during an end-user’s daytime hours unless it is urgent.
3. SMS campaigns should support HELP/STOP messages, and similar messages, in the end-user’s local language.
4. Do not contact end-users on do-not-call or do-not-disturb registries.

Polish mobile operators do not support Numeric Sender IDs; these will be overwritten with a generic Alphanumeric Sender ID outside the Twilio platform to facilitate delivery. It is highly recommended that you send from a Alphanumeric Sender ID to avoid blocking and filtering.
