Platform and reliability

Network multiplexing maintains backup routes, and traffic is automatically re-routed to the optimal path the moment delivery quality on a route falls below SureM thresholds.

SureM’s platform is built around direct connectivity across 200+ countries and 800+ carriers for international delivery planning.

Global traffic is watched around the clock with alarm systems and DLR speed tracking, and SureM also publishes 24/7 customer service for active operations.

Every customer is assigned a dedicated account manager who provides real-time monitoring of success/failure/volume rates and delivers weekly performance reports with consulting.

Where SMS verification is blocked or unreliable, ACS (Auto Calling Service) delivers authentication via multilingual prerecorded voice — reaching countries that SMS OTP alone cannot serve.

IMSI-based lookup checks country, carrier, handset availability, portability, and roaming before send, so virtual numbers, landlines, and unreachable numbers are filtered out early.

SureM contributed to the international SMPP standard and operates SMPP v5, plus MM4 (SMTP between MMSCs) and MM7 (WAP/OMA MMSR) interfaces for MMS integration.

Excel-driven desktop sending program that can dispatch up to 1,000,000 personalized SMS/MMS messages per batch with scheduled send, duplicate-number checking, and per-recipient templates — for teams that cannot integrate directly.

SureM is an AWS official partner for cloud-based messaging infrastructure and elastic scaling.

Current partner and platform proof also mentions REST API and SMTP integration, real-time delivery dashboards, and dedicated gateway options for enterprise customers.
