FaxTerra vs OTG Networks vFax

FaxTerra is an online fax service for sending and receiving documents through a web browser, iPhone app, or Android app. It provides a virtual fax number and supports international faxing. The free plan allows 10 pages per month sent to fax numbers in the US and Canada; it does not require a credit card and has no ads, watermarks, or branding. Sending stops when the page allowance is used, and incoming faxes beyond it remain inaccessible until a refill or upgrade. FaxTerra accepts PDF, JPG, PNG, HEIC, TIFF, GIF, BMP, and WebP files. Teams can share a number, inbox, sent history, and monthly pages, with unlimited invitees and no per-user fee. Delivery confirmation arrives by email, and fax status can be checked at any time. FaxTerra advertises 256-bit encryption; paid plans can add HIPAA compliance with a signed BAA, PHI-free notifications, and a six-year audit log. Purchased credit pages never expire. The Starter plan costs $4.99 a month; other options include one-time credit packs and a one-time fax number for 90 days.

OTG Networks vFax lets users send and receive faxes through email, a browser, or a device without fax hardware. To fax from email, users attach a PDF and enter the fax number in the recipient field; incoming faxes arrive as PDF attachments in the inbox. The web portal supports drag-and-drop documents, fax history, and management of multiple fax numbers. Customers can obtain a dedicated local or toll-free number or port an existing number. Delivery receipts report a timestamp, pages delivered, and recipient confirmation. The service is listed for Android, iOS, macOS, web, and Windows. OTG describes vFax as HIPAA compliant and says it uses encryption in transit and at rest, role-based access controls, and audit logs; it also lists 256-bit encryption and SOC 2 readiness. The page advertises unlimited cloud storage. The vFax plan is included free on every GoOTG plan, while the general pricing note starts at $15/user/mo. OTG identifies healthcare, legal, finance and banking, and real estate as industries that rely on vFax.
