Frequently Asked Questions
Use an SMS API provider like Twilio, Sinch, MessageBird, or Plivo. Ensure the recipient's number is in E.164 format (+58) and be aware of carrier-specific limitations on sender IDs and message length. Due to two-way SMS not being supported, you cannot receive replies via SMS.
The three major mobile operators in Venezuela are Movistar, Digitel, and Movilnet. While SMS is still used, messaging apps like WhatsApp and Telegram have gained popularity due to economic factors and internet availability.
Standard SMS character limits apply: 160 characters for GSM-7 encoding and 70 for UCS-2. Concatenated messaging is not supported, so messages exceeding these limits will be truncated. UCS-2 encoding is only supported for Movilnet.
MMS messages are automatically converted to SMS with an embedded URL link. Multimedia content must be hosted externally and accessed through the link. This conversion ensures compatibility across Venezuelan networks.
Obtain explicit consent before sending marketing messages, support HELP/STOP commands in Spanish and English, and honor opt-out requests within 24 hours. While no DNC registry exists, maintain internal suppression lists.
Alphanumeric sender IDs are supported with restrictions. Pre-registration, taking 21 days, is required for Digitel. Other networks might overwrite sender IDs with random codes. Sender ID preservation is only guaranteed for pre-registered IDs on Digitel.
Sending SMS to landlines in Venezuela is not supported. Attempts result in a 400 error (code 21614), and the messages will not be logged or charged.
Yes, but strict regulations apply. You must obtain explicit consent, honor opt-outs, and comply with advertising guidelines. Avoid sending messages outside of 8:00 AM to 8:00 PM local time, except for urgent notifications.
Send messages between 8:00 AM and 8:00 PM Venezuela Time (VET, UTC-4). Avoid sending during national holidays. Urgent messages can be sent outside these hours.
Rate limits vary by provider: Twilio (250/sec), Sinch (30/sec), MessageBird (100/sec), and Plivo (50/sec). Implement queuing systems and backoff strategies to handle large volumes.
Process opt-out requests (STOP, PARA, CANCELAR, AYUDA, HELP) within 24 hours, send a final confirmation message, and update your suppression lists. Retain opt-out records for at least 2 years.
Number portability is not available in Venezuela. Mobile numbers stay linked to their original operator, affecting routing and delivery strategies.
Keep messages under 160 characters, localize to Spanish, personalize, and include clear calls-to-action. Respect local time zones, and limit messages to 2-3 per week per recipient.
Test across all major carriers (Movistar, Digitel, Movilnet) using test accounts with your chosen SMS provider. Monitor delivery rates, track carrier-specific errors, and test opt-out functionality regularly.
Venezuela SMS Best Practices, Compliance, and Features
Venezuela SMS Market Overview
Market Conditions: Three major operators dominate Venezuela's mobile market: Movistar, Digitel, and Movilnet. While SMS remains essential for business and authentication, messaging apps like WhatsApp and Telegram have gained significant popularity due to economic conditions and internet accessibility. Android devices dominate due to affordability and wider availability compared to iOS devices.
Infrastructure and Reliability Context: Expect potential delivery delays, network outages, and infrastructure reliability issues when implementing SMS services in Venezuela. The country is undergoing a major network transition, with 2G services phasing out by the end of 2025 – Digitel and Movistar have already shut down their 2G networks, leaving state-backed Movilnet as the sole remaining 2G provider. This transition impacts traditional SMS delivery methods as networks shift to 4G and emerging 5G technologies.
As of January 2025, the operator landscape shows: Movistar holding approximately 54% market share with over 7 million customers, state-owned Movilnet maintaining nearly 40% market share, and Digitel with approximately 15% market share and 3 million subscribers. Following Venezuela's first spectrum auction in a decade (January 2025), Digitel acquired 3.5 GHz band spectrum for $86 million to expand 5G FWA services, while Movistar obtained 2.5 GHz band spectrum for $37 million to deepen 4G LTE coverage. These investments signal ongoing network modernization – prepare for continued infrastructure changes affecting your SMS services.
SMS Capabilities and Features in Venezuela
Venezuela offers basic SMS functionality with limitations on advanced features and specific restrictions on sender IDs and message delivery.
Note on Network Transition Impact: The ongoing 2G network shutdown (completion by end-2025) directly affects SMS capabilities, particularly for concatenated messages and routing. As operators transition to 4G/5G-only networks, SMS delivery increasingly relies on IP-based messaging protocols (SMS over IMS). Test SMS delivery across all carriers during this transition period and monitor delivery success rates closely, as legacy SMS features may behave differently on newer network technologies.
Two-way SMS Support
Venezuela networks do not support two-way SMS. You cannot receive replies to your SMS messages through standard SMS channels.
Alternative solutions for two-way communication:
Concatenated Messages (Segmented SMS)
Support: Venezuela networks do not support concatenated messaging.
Message length rules:
What happens when you exceed limits: Messages exceeding character limits will be truncated without warning. Characters beyond the limit will not be delivered. Always validate message length before sending.
Encoding considerations: Only Movilnet supports UCS-2 encoding, while GSM-7 works across all networks. Movistar may replace or flatten UCS-2 characters in your messages.
Character counting examples:
Best practice: Keep messages under 150 characters to account for carrier modifications and special character handling.
MMS Support
Networks automatically convert MMS messages to SMS with an embedded URL link. Host multimedia content separately and share it via a link within your SMS message body.
URL hosting requirements:
Conversion example:
Recipient Phone Number Compatibility
Number Portability
Venezuela does not offer number portability. Mobile numbers remain tied to their original carrier, which affects your message routing and delivery strategies.
Sending SMS to Landlines
You cannot send SMS to landline numbers in Venezuela. Attempts to message landline numbers will result in a 400 response error (code 21614), and these messages will not appear in logs or incur charges.
How to detect landline vs mobile numbers: Venezuelan mobile numbers follow these patterns:
Venezuela SMS Compliance and Regulatory Requirements
CONATEL (Comisión Nacional de Telecomunicaciones) regulates Venezuela's telecommunications sector. While specific SMS marketing regulations are still evolving, adhere to general consumer protection laws and telecommunications guidelines.
Current regulations (as of January 2025):
Penalties for non-compliance:
Regulatory Authority: CONATEL oversees all telecommunications services and requires operators to be properly authorized. In September 2025, President Nicolás Maduro approved the National Plan for Telecommunications 2025-2031, signaling continued regulatory focus on telecommunications sector development. CONATEL emphasizes consumer protection and advises users to verify that any telecommunications service provider is properly authorized before contracting services. For SMS services, ensure you work with CONATEL-authorized operators and maintain compliance with consumer protection standards enforced by INDEPABIS (Instituto para la Defensa de las Personas en el Acceso a los Bienes y Servicios).
