My son has a cellphone contract with O2 in the UK and he cannot connect to my 087 number.
1) Is this a problem with O2 or with all UK networks?
2) Will he be able to connect if I port my 011 geographic number or will the network still see it as a non-Telkom number and so not connect?
Unfortunately, 087 number cant be called from international destinations. Should you port your 011 number he will be able to.
That could be a possibility.
