Do I need a fax number to send a fax from my iPhone?
To receive faxes, yes — you need a dedicated virtual fax number. To send a fax, most apps let you do it without a permanent number. mFax lets you send faxes quickly without committing to a monthly number subscription.
Is it safe to fax sensitive documents from an iPhone?
Yes, provided you use a reputable app. Look for TLS encryption in transit and secure storage at rest. For healthcare documents, use an app with HIPAA compliance and a Business Associate Agreement — Fax.Plus and eFax both offer this.
