When you’re sending and receiving text messages to/from your candidates, you will be charged in credits. In this article, you can learn all about how credits are calculated.

Character counter

Whenever you send an SMS to a candidate, you will see a character counter in the bottom right of the message creator. This means there will be no surprises in the credit transactions from your account.

But let’s look in to the details on characters and credit are counted.

We charge you 1 credit per incoming and outgoing SMS. How one SMS is calculated depends on the number/type of characters, and other factors as what country you text, and how many the SMS is sent to. Let’s look in to some specifics.

Encoding

All characters added to your text message is using one of the following encodings: 7-bit or Unicode. When using 7-bit, you are allowed to use 160 characters in one SMS, and when using Unicode this is limited to 70 characters.

The message length for 7bit encoding is up to 160 characters.

Unicode encoding (UCS-2)

The Unicode encoding supports a much bigger range of characters/languages. Whenever you add a character not listed in the 7-bit alphabet, the Unicode encoding is automatically used. Since these characters takes up a lot more space, the message length is reduced to 70 characters per SMS (credit).

Multipart SMS messages

When your message exceeds the character limit of 160 characters (7bit encoding) or 70 characters (UCS-2 encoding), the message is split up in multiple SMS. When this happens, the allowed characters per SMS is a bit shortened (this is to make sure the multipart SMS is delivered in a good way to the receiver). The length of the 7-bit message is shortened to 153 characters, and the Unicode message is reduced to 67 characters.

One entire text message can contain up to 1600 characters in total, and will be charged several credits.

Opt out message

When you’re sending bulk messages to candidates, you are legally entitles to include the option to out out of any further messages. This is therefore automatically added to the end of the first bulk message sent to the specific candidate. This characters are included in the total amount of characters per SMS.

Reply to messages

Some countries have a dedicated phone number for SMS services and for the candidate to be able to reply, a specific phone number to reply is added. This will also be added to the total amount of characters per SMS. This message will look something like this ↓
