My Virgin Media Landline wont connect to my 3 mobile phone

My Virgin Media Landline wont connect to my 3 mobile phone just says my mobile is unavailable leave a message. Works perfectly ok with all other mobile networks. Have talked to Virgin Media they say its routing ok but something at the 3 end is blocking it?

Does your phone have a built in spam caller detection feature? If so, it might be blocking numbers that call from a specific area code. In this case, VM numbers. Have a look in the dialler app's settings to see if there is some kind of filter active. If there is, try turning it off and test again.

Yes, its turned off along with everything else. My wife has a Samsung S21, until recently she was with 3 (now 02 for the roaming!) and had the exact same problem as me so not sure what's going on? All started around October 2023 the same time with had to start using the area code for local calls from VM landline and a lot of VM Broad Band problems.
