SMS encoded using Unicode, allowing non-Latin languages such as Hindi, Arabic, Chinese, Japanese, and emojis, with a lower character limit than GSM encoding.
Why Unicode SMS Matters
Standard GSM 7-bit encoding only covers a limited Latin character set. The moment a message includes a character outside that set, a regional script, an emoji, even certain punctuation, the entire message has to switch to Unicode encoding, which drops the per-segment limit from 160 characters to 70.
How Unicode SMS Works
Unicode SMS uses UCS-2 encoding instead of GSM 7-bit. A single segment holds up to 70 characters; a message longer than that is automatically split into concatenated segments of 67 characters each to leave room for the multipart header, and reassembled on the handset.
How SMPPCenter Uses This
SMPPCenter automatically detects when a message body contains non-GSM characters, encodes and segments it correctly as Unicode, and bills it per segment the same way any multi-part message is billed.
