Since Thursday I am having a recurring problem with my Fido home phone.... sometimes with incoming calls the handset doesn't ring and the caller goes straight to voicemail (tested with tested with four different phone lines), and for outgoing calls nothing happens, I just get a busy signal (on phones that are active and not busy, this was tested with two different cell phones). The problem definitely is not the cordless handset because I swapped out with another one and still had the same problem. After switching off the modem a few times without success I pulled the battery out and pulled the power plug and that seemed to fix the problem....but then it came back. Based on this, it seems to me the problem lies with either the modem and/or the sim card. What do I do?

Hey @mrgroot and thanks for reaching out.
Sorry to see that you're having so much trouble with your home phone.
I do see that you mentioned trying to unplug the modem and removing the battery as well. Did you get a chance to remove and put back in the sim card?
And you said you switched modems already. Were your old modems giving you the same issue?
Let me know.
