We use telemetry and cookies to optimize your signaling calculation experience. Enabling data streams helps us fund mission-critical R&D.
Professional messaging utility for analyzing SMS segmentation and encoding efficiency across GSM 7-bit, UCS-2 (Unicode), and 8-bit data formats.
SMS encoding calculators count segments and UDH overhead for GSM 7-bit vs UCS-2 so campaigns and A2P traffic plans reflect real submit volume.
The analyzer processes the input text according to 3GPP TS 23.038 standards. it determines the optimal encoding based on the character set used and factors in the 6-byte UDH required for multi-segment message reassembly.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
Addresses the 140-byte (1120-bit) physical limit of the GSM Short Message Service. Essential for CPaaS platform developers and SMSC gateway architects.

A 120-character message with one emoji typically becomes UCS-2 and may need two segments—double the GSM-7 expectation.
National language locking and shift tables can alter 7-bit packing.
GSM 7-bit fits 160 chars in one segment (153 with UDH concatenation). UCS-2 drops to 70 (67 with UDH). Emojis and non-Latin scripts often force UCS-2.
User Data Header carries concatenation and port info, reducing available user characters per segment.
Segment fan-out multiplies submit TPS and delivery attempts. A “one SMS” campaign can be three segments each.
