@deepcman, The only thing I knew beyond your last reply is you are not able to call forward on your S24 but you can on your S20 you give no other information, I'm not a mind reader to know the method you are using to call forward you further stated you read that it is a bug in One UI 6.1 but give no source of this, if it is a bug in One UI 6.1 what are you expecting Fido tech department to do about it? Samsung is the one that needs to fix it.
I asked for the steps you took to enable call forwarding because if you used *21*(10 digits)# on the S20 and it worked then the call forwarding should stick and the call should still be forwarded if you put the SIM card in another phone.
I've tested this and it works although the only phones I have access to at the moment are Pixel devices I can test it on my boy's devices when they get home as they have Samsung devices, what I would suggest though is if you have recently upgraded to One UI 6.1 I would strongly suggest a factory reset as sometimes bugs can occur after a major update.
Hi @deepcman , it should work. Did you call tech support to have your network reset or for assistance with troubleshooting your issue? You can call *611 from your device and request assistance from technical support. Or you can try reaching out to fidosolutions on Twitter or Facebook and request assistance through direct messaging. Hope that helps you out. Cheers
Hi again @deepcman , did you try a network reset yourself on your device? You can find that under general management, reset, network reset
Hey @deepcman 
Feel free to contact our Tech Support team for further assistance, if this is still unresolved!
They'll be happy to look into it with you.
