AVISO Messaging — Wholesale A2P SMS, Business Messaging & eSIM

AVISO Messaging Ltd is an independent wholesale A2P SMS aggregator and messaging carrier, and a member of the 42com Group. We provide direct-route SMS termination, OTP and authentication delivery, OTT business messaging, voice messaging, managed services and global eSIM connectivity to mobile network operators (MNOs), SMS aggregators, CPaaS platforms and enterprises.

What we do

• A2P SMS Termination — direct routes declared per destination, with full delivery receipts (DLR) and no grey routes.
• OTP & Authentication — first-attempt one-time-passcode delivery, protected against artificially inflated traffic (AIT).
• Notifications & Marketing — reminders, alerts and promotional messaging at scale.
• iGaming & Betting — burst capacity for peak fixtures and time-sensitive traffic.
• OTT Messaging — WhatsApp, Telegram, Viber and RCS business messaging.
• Voice Messaging — voice OTP to landlines and lapsed SIMs.
• Managed Services — your messaging back office, staffed by our team.
• eSIM Connectivity — white-label global eSIM data across 190+ destinations, delivered by QR code or REST API using GSMA remote SIM provisioning (eUICC / SM-DP+).

Global coverage

AVISO delivers to more than 190 destinations worldwide with declared, direct routes. Every destination carries a route class and a full DLR chain, and suspected AIT is flagged transparently with evidence rather than silently absorbed. Coverage spans Europe, the CIS, the Middle East, Africa, Asia-Pacific and the Americas.

Why AVISO

We compete on directness and transparency: declared direct routes, first-attempt OTP delivery, real-time AIT protection, and honest routing. Where a market is transit-only, or a rate quoted elsewhere isn’t real, we tell you. Built to excel, scaled to deliver.

Who we serve

Mobile network operators, SMS aggregators, CPaaS and communication platforms, and enterprises that need reliable A2P messaging and global eSIM connectivity.
