AVM Networks Limited

Japan Wholesale A2P SMS Termination & Carrier Gateway

AVM Networks Limited delivers reliable enterprise wholesale A2P SMS termination into Japan (+81). Interconnecting directly with Japan's primary mobile network operators—NTT DOCOMO, KDDI (au), SoftBank, and Rakuten Mobile—our messaging gateway provides high-speed transactional OTP authentication, order alerts, and enterprise notifications. In Japan, domestic mobile operators do not support arbitrary alphanumeric Sender IDs; incoming international messages are delivered using operator-allocated local numeric routes or registered short codes (such as SoftBank short codes and KDDI numeric pathways). AVM Networks ensures seamless delivery across all Japanese mobile subscribers with authentic handset delivery receipts and full compliance with the Act on Specified Commercial Transactions.
