I am sorry if no one answered your post until now.
Here is some troubleshooting I can suggest:
- Dial ##21# which would deactivate any accidental unconditional call forwarding.
- Remove your battery and SIM card completely for 5 minutes and then put them back in.
- Try to call your cell phone from another line.
If it is still not working, I suggest that you call our technical support team who can assist you further. You may reach them at 1-888-481-FIDO(3436), options 3 - 4 - 2.
I hope this helps!
