As the title says I have lost the ability to forward calls from my work cell phone to my personal cell phone and ONLY this number. I can forward to other mobiles and landlines just not this one. I can forward from the number in question no problem.
This all started when I reverted back from esim to physical sim yesterday. I simply can not forward calls to one number. Very odd. I have been to Spark who say there is nothing wrong with the provisioning / activation of the sim card.
Other info....... cell phone is an iPhone XS running latest official firmware 12. whatever it is.
Any help would be GREATLY appreciated!
Thanks in advance
