What do I need to send SMSs?
SMS Text Messaging is an In-App Purchase (IAP) service that requires prepaid credits to work.
How many types of SMSs are there?
There are 2 types: GSM7 and UNICODE.
GSM7 is the standard format, with a limit of 160 characters per message, that includes the following characters:
UNICODE is the format applied if a special character, that is not in the GSM7 list, is used. Limit per SMS: 70 characters.
For GSM7 SMS the size limit is 160 characters, and for Unicode is 70. Above these limits, the content is divided into a multi-part message and the limit of characters is lowered to 153 for GSM7 and to 67 for Unicode. The system will inform you in real-time about the number of SMS your message represents.
How much does it cost to send an SMS?
The number of SMSs a message represents will be always available to you in your database.
How do I buy credits?
Or go to.
If you are on Odoo Online (SAAS) and have the Enterprise version, you benefit from free trial credits to test the feature.
More common questions
Is there an expiration time for my credits?
No, credits do not expire.
Can I send an SMS to a phone number (which is not a mobile phone) because I see the icon in front of the field “phone”?
Only if that phone number supports SMS (e.g. SIP phones).
Do I receive an invoice to buy my credits?
Can the recipient answer to me?
No, it is not possible to reply to the SMS.
What happens if I send multiple SMS but I do not have enough credits to send them all?
The whole transaction is counted as a single one, so no SMS will be sent until you have enough credits to send them all.
Do I have a history of the sent SMSs?
Yes, the SMS is logged as a note under the chatter of the corresponding record, and a complete history of the SMSs sent is available on Developer mode under .
Can I send as many SMSs I want at once?
Yes, if you have enough credits.
If I have a number that does not exist in the list of recipients, will I lose credits?
Not if the phone number is in the wrong format (e.g. too many digits). Otherwise, if the SMS is sent to the wrong person or to a fake number, the credit will be lost.
What happens if I send my SMS to a paying number (e.g.: a contest to win a ticket for a festival)?
The SMS will not be delivered to that kind of number, so you won’t be charged.
Can I identify the numbers that do not exist when I send several SMSs?
Only the ones that have an invalid format.
