How much am I charged for a long SMS?

Pricing for a single SMS is listed on our pricing page. For long messages that are split into parts you are charged the cost of a single SMS multiplied by total parts.

Take for example, a message that is 200 chars in length and sent to a destination that costs $0.0075. If the message contains only GSM characters, it will be split into two parts (153 chars + 47 chars) and you will be charged $0.015 (2 x $0.075) and if the message contains one or more unicode chars, it will be split into 3 parts (67 chars + 67 chars + 66 chars) and you will be charged $0.0225 (3 x $0.075). The message split is only for billing purposes, it will show up as a single concatenated message on most mobile handsets

What is the character limit for an SMS?

A single SMS can allow upto 140 bytes which is 160 GSM encoded characters (7 bits each) or 70 unicode-encoded characters (2 bytes each). If your text contains characters that are not in the GSM charset, it will be treated as a unicode message
