Firenet is attempting to take advantage of the mess left by troubled broadband ISP Prodigy.
It has been reported that Prodigy may have run into financial difficulties of late, with both BT and Ofcom failing to contact the firm recently.
BT have set up a "walled garden" for Prodigy users attempting to access the service making it easier for customers to pick up their Migration Authorisation Codes and move elsewhere.
The wholesaler announced it has cut off access for Prodigy, leaving the door open for ISPs such as Firenet to lure subscribers jumping ship.
Firenet has announced: "As a special offer to help get Prodigy Internet users back online, we are offering free migration (usual price £12.65 inc VAT).
"We can also offer you a completely free dial-up internet connection you can use until we can get your broadband transferred."
