  1. [R3] eFax® Plus-Pro-Protect 3/5 · US Issues viewing faxes: I am receiving the fax but unfortunately I can’t open the faxes. I contacted customer service previously. The app is not functioning like it should.
  2. [R4] eFax® Plus-Pro-Protect 1/5 · US Jenna: Faxes don’t load, app runs slow
  3. [R5] eFax® Plus-Pro-Protect 5/5 · US 🔥🔥🔥🔥: A-1 Hotsauce! I never missed a fax and never had a problem sending a fax! Flawless💨
  4. [R6] eFax® Plus-Pro-Protect 3/5 · US Not Great So Far: I downloaded the app, logged in and sent 4 pages just to text it out. It said it would notify me once pages were sent, but in the interim… there was NO indication that the pages were transmitting. It took 20mins before I saw the fax in my Sent folder and I have yet to receive the “notification”. This is concerning as the primary reason I downloaded the app was to RECEIVE faxes, n
  5. [R1] eFax® Plus-Pro-Protect 1/5 · US Can’t login: Can’t login with the same username and password as on website
  6. [R8] eFax® Plus-Pro-Protect 4/5 · US It’s a pretty good app: It works pretty well, however on iPad or iPhone basically iOS, it has issues finding drives being able to save things where you want or open documents that are not in your recently access items. That’s why I gave it four in addition to all that it keeps wanting to close so if I can’t find your document an attachment, you minimize it and go to open up the attachment so it’s
  7. [R13] eFax® Plus-Pro-Protect 1/5 · US SCAM: Customer service can not assist with personal or business accounts. Plus cancellation is unavailable under billing as they instructed. It’s a scam to charge your card
  8. [R14] eFax® Plus-Pro-Protect 5/5 · US Easy to use: Really it's amazing, you can use it so easily, and the money you pay them totally worth.
  9. [R16] eFax® Plus-Pro-Protect 1/5 · US Beware: Company keeps credit card on file and continues to bill you after app is canceled
  10. [R25] eFax® Plus-Pro-Protect 5/5 · US Love this app: I didn’t realize that faxing was coming back around, especially in medical settings, and this app has been a lifesaver. Worth every penny.
  11. [R2] eFax® Plus-Pro-Protect 5/5 · US I DK: Sent a fax, and had some issues. Reached out to customer support, they confirmed delivery and ensured my issues were taken care of. I had frustrations initially, never having used an e-fax service before but eFax is definitely my choice moving forward!
  12. [R30] eFax® Plus-Pro-Protect 1/5 · US Shady billing!: Do not sign up for this junk! They have a shady billing system in which they even try to make you sign up for another e-fax type service instead of taking you to a cancellation page that you attempt to click on but won’t be successful. Once “canceled” don’t think you are out of the woods yet, nope because you WILL BE BILLED until the “billing cycle ends.” Good luck! Hope that helps
  13. [R26] eFax® Plus-Pro-Protect 1/5 · US Free Trial Didn’t Work: I was charged a monthly fee the same day I started the free trial. I want my money back…

  16. [R54] eFax® Plus-Pro-Protect 1/5 · US Deceptively charges by the minute: I signed up for a 170 page 7 day trial which allegedly is supposed to be free. However, I noticed a $10 charge even though I only sent 85 pages and properly canceled my trial subscription prior to the termination of the seven days. When I called to ask why I was charged $10. I was told that I sent 269 pages because a 30 page fax took nearly 2 hours to send desp
  17. [R36] eFax® Plus-Pro-Protect 1/5 · US Scam: Be careful and be prepared for the fact that you will not be able to unsubscribe. I have tried all the methods and so far it has not worked. The instructions for unsubscribe do not work, I wrote to the email - «unavailable» , I wrote to the support - «our team is currently not working». I will try to dispute the transaction with the bank...
