can't call a phone #

[Granny5]

Can call anyone except one phone number, my wife's, so it is a big problem.

Thanks for the suggestions everyone - it turned out that call waiting had somehow been switched on.

Hi @Granny5 

There are so many funny comments to make but I'll be good. LOL

Try this. Swap SIM cards. Turn off both phones and swap SIM cards. Reboot. Then try calling her and see if that works. If it does, then it's a setting on the phone that seems to be the culprit. If it doesn't work then the network for some reason is blocking it. OR if you have iPhones, sometimes if the phone number isn't in the contacts or sometimes even when it is, go into your settings and turn off the block unknown callers. That was a huge problem on mine and even blocked some of my contacts.

@Granny5  Does she maybe have you blocked by accident . Can you swap swap SIM cards and is it same results
