Can I use 123FREE service plan for faxing?

ZONE Telecom > Consumer > 123FREE
123FREE service plan is not suitable for fax transmission.  However, if you wish to use our service for faxing, you should select 1511FAX plan which is dedicated for fax transmission.
Alternatively, you may select at least two service providers from the LCR carriers which marked with the little “fax” icons signify that the carriers have been designated and they are “Good for Fax”.
