I travel constantly for work, and lugging around a fax machine or waiting until I’m back in the office was never practical. I finally looked into mobile faxing and found some reliable options through https://etcherpc.com . They highlight services that have secure apps with proper encryption, so you’re not putting sensitive data at risk. Now I can send and receive faxes safely from airports or hotels with just my phone. It’s been a lifesaver and hasn’t compromised security one bit.
