Libya SMS Best Practices, Compliance, and Features

Libya SMS Market Overview

Market Conditions: Libya's mobile market is dominated by two major operators - Almadar Aljadid and Libyana. SMS remains a critical communication channel, particularly for business messaging, despite growing adoption of OTT messaging apps. The market faces unique challenges due to political instability affecting telecommunications infrastructure. Android devices hold the majority market share compared to iOS.

Key SMS Features and Capabilities in Libya

Libya supports basic SMS functionality with some limitations on advanced features, focusing primarily on one-way messaging capabilities with support for concatenated messages.

Two-way SMS Support

Two-way SMS is not supported in Libya through standard SMS providers. This limitation affects interactive messaging campaigns and automated response systems.

Concatenated Messages (Segmented SMS)

Support: Yes, concatenated messages are supported in Libya, though support may vary by sender ID type.
Message length rules: Standard SMS length limits apply - 160 characters for GSM-7 encoding and 70 characters for UCS-2 encoding before splitting occurs.
Encoding considerations: Both GSM-7 and UCS-2 encodings are supported, with UCS-2 required for Arabic text messages.

MMS Support

MMS messages are not directly supported in Libya. When attempting to send MMS, the message is automatically converted to SMS format with an embedded URL link where recipients can view the multimedia content.

Recipient Phone Number Compatibility

Number Portability

Number portability is not available in Libya. Mobile numbers remain tied to their original network operators, simplifying message routing but limiting consumer flexibility.

Sending SMS to Landlines

Sending SMS to landline numbers is not supported in Libya. Attempts to send messages to landline numbers will result in delivery failure, typically generating a 400 response error code (21614) from SMS APIs, with no charges incurred.

Compliance and Regulatory Guidelines for SMS in Libya

Libya currently lacks comprehensive SMS marketing regulations, but businesses should follow international best practices to ensure responsible messaging. The Communications and Information Technology Authority (CITA) oversees telecommunications but has limited specific SMS guidelines.

Consent and Opt-In

While explicit regulations are limited, implementing strong consent practices is crucial:

• Obtain clear, documented opt-in consent before sending marketing messages
• Maintain detailed records of how and when consent was obtained
• Provide clear terms and conditions during the opt-in process
• Include your business name and purpose in consent requests

HELP/STOP and Other Commands

Required Commands:

• Support for STOP/UNSUBSCRIBE commands is recommended
• Include opt-out instructions in Arabic and English
• Common keywords: STOP, CANCEL, UNSUBSCRIBE (توقف, إلغاء)
• Process opt-out requests within 24 hours

Do Not Call / Do Not Disturb Registries

Libya does not maintain an official Do Not Call or Do Not Disturb registry. However, businesses should:

• Maintain their own suppression lists
• Honor opt-out requests immediately
• Document all opt-out requests and actions taken
• Regularly clean contact lists to remove inactive numbers

Time Zone Sensitivity

Libya operates in Eastern European Time (UTC+2). While no strict time restrictions exist:

• Send messages between 9:00 AM and 9:00 PM local time
• Avoid messaging during prayer times
• Respect Ramadan schedules
• Only send urgent messages outside recommended hours

async function sendSMSToLibya(
  to: string,
  message: string,
  senderId: string
) {
