E-Fax Comparison
The internet fax service industry is old, established, and very competitive. So, why is e-fax raising prices to their customers? Well, it's because they can. For one, they are the industry leader. However, another reason is that they have found a way to lock in their customers. Once someone opens an account and chooses a fax number, e-fax will never let them transfer that number away. Here's their standard response to anyone trying to move to a new, low cost fax provider:
"J2 Global rejects the LOA to port the fax number. j2 Global® is the customer of record for this number, and as such, we are rejecting the request to port this number out. We sell bundled services on our DIDs, and do not grant our users the right to port out the number we assign to them"
In the telecom industry, porting a number is a standard process. You can change your cell phone carrier and keep your number. It's the same in the fax industry, except for e-fax.
