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.

Mobile operators Vodafone and Orange in Romania do not support Dynamic Sender IDs. These IDs will be overwritten with either a generic short code or an Alphanumeric Sender ID to ensure delivery.

Romanian mobile operators are blocking and filtering SMS content containing web addresses (URLs). If your SMS content carries a web URL, kindly reach out to Twilio customer services to get your SMS content added to an allow list to prevent delivery failure. When content registration is complete, you must send the messages with an International Long Code Sender ID or an Alphanumeric Sender ID. Sending messages using Domestic Long Code Sender ID may result in messages containing a web URL being filtered.

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.

N/A

Messages with alphanumeric Sender IDs sent to the Orange, Vodafone or Digi.Mobil networks will be overwritten with either a generic short code or an Alphanumeric Sender ID outside the Twilio platform.

Best practices

Romania is a country very sensitive to URLs. Even if the Sender ID gets registered, sending messages containing a URL that is not checked and allowlisted may produce issues in the delivery so we would like to suggest our customers to proactively provide us with the full list of ULRs they intend to use during Sender ID Registration procedure as sample SMS messages.

Twilio will check them and make sure they are allowlisted.

In case new URLs need to be used in the future please reach out to Twilio customer services to get the new URL allowlisted alongside the sender ID you have registered
