Telgorithm's answer:
Telgorithm was established in 2021 by telecom veterans who, with 20+ years of experience, saw a massive need to set a new standard for quality, support, and transparency in the cloud communication space - particularly for A2P 10DLC messaging.
Telgorithm was founded on the principles of transparency, customer experience, responsibility, education, and empathy. We’ve developed innovative technology solutions for 10DLC messaging, but our services go far beyond our API product. Telgorithm is committed to providing the guidance and support needed to be successful in the evolving A2P landscape.
