Who Vonage is
Vonage (formerly Nexmo, now owned by Ericsson) offers a mature omnichannel Messages API — SMS, MMS, WhatsApp, RCS, Viber, and more — plus unified communications (business phone and contact center) and global reach across 160+ countries.
Who SimplyRCS is
SimplyRCS is the US-focused, everything-included messaging alternative: RCS-led with SMS/MMS fallback, a no-code builder and two-way inbox, white-glove carrier approval, and carrier-rate, transparent pricing — the API and the app at the same price.

Businesses that want omnichannel messaging APIs alongside unified communications (voice, video, contact center) and broad international reach under one vendor.
Where SimplyRCS wins
A US business that wants verified, branded RCS live in weeks — with the app, API, inbox, and carrier approval included, at published carrier-rate prices with every fee itemized.
