• Step #5: Evaluate the customer support of each provider. Look for a friendly and dedicated support team with a comprehensive knowledge base.
• Step #6: Ensure compliance with local regulations and laws. Look for a provider that abides by legal requirements and obligations.
• Step #7: Explore the customisation options and reporting capabilities of each provider. Choose an SMS API with a developer-friendly interface and reporting capabilities.
• Step# 8: Assess the security features of the API. Check for encryption, backup, and recovery systems and strong backup and recovery systems in case of any emergencies or disasters.
• Step #9: Check the scalability of the API to handle large volumes of messages. Choose a multichannel SMS API that can handle your peak traffic. Ensure that it can scale up or down as needed.
