[Anon15]

Changed from EE to Sky kept my number - sometimes people have said call not connect and i get the same just blank noise when dialling out when using  - noticed some recent have grey white text P or D next to name in call histroy. And texts failing to send to regular contacts

Assuming Sky have said that your number has transferred does your mobile itself now show the correct number as sometimes it might not so would need updating to the correct one. If this is correct then a replacement sim might fix this issue as it will come with your transferred number:

The transfered number shows correct on the phone as Primary. I can return a calls in the recents list from the numbers with a D next to them but can not call same number with a P in grey box.
