Wholesale SMS Termination & A2P Gateway | AVM Networks Limited

Q: What is International SMS Termination and how does cross-border routing work?

International SMS Termination is the process of transmitting an Application-to-Person (A2P) or Person-to-Person (P2P) message from an enterprise gateway across international borders to a subscriber handset on a foreign mobile network operator (MNO). The message travels via secure SMPP v3.4/IPX connections to the destination operator SMSC, which delivers the message over the local cellular radio access network.

Q: How do International Termination Rates (ITR) and Origin-Based Rating (OBR) impact messaging costs?

Destination mobile operators charge International Termination Rates (ITR) for receiving cross-border messages. Under Origin-Based Rating (OBR) frameworks (common in Europe and Latin America), the cost varies depending on the country of origin associated with the sender ID. AVM Networks utilizes automated origin-verification algorithms to ensure compliance with operator pricing tiers and eliminate surprise surcharges.

Q: What is the character limit difference between GSM 7-bit and UCS-2 Unicode?

Standard Latin characters using GSM 7-bit encoding allow 160 characters for a single SMS (or 153 characters per segment for concatenated messages). Multi-language scripts such as Arabic, Hindi, Chinese, and emojis require UCS-2 16-bit Unicode encoding, which allows 70 characters per single message (or 67 characters per segment in concatenated multi-part messages due to User Data Header overhead).

Q: What notice period is provided for international rate deck price adjustments?

AVM Networks provides standard 7-day advance notice for international A-Z rate deck updates via automated bilateral CSV distribution and customer portal synchronization.
