Universal reach. Every phone, every country, every carrier.
SMS is still the most universal messaging channel on the planet. Arka's SMS connector abstracts the differences between providers and regional carriers, giving you one API for Twilio, Vonage, AWS SNS, MessageBird, and more.
Different countries have different rules: sender ID registration, short-code approval, opt-in logging, regional DLT. Arka builds those rules into the routing layer so your messages get through the first time.
