Hi Dhilum,
Thanks for your post and welcome to our community.
Really sorry you've been having some issues with the service since porting over, this isn't good.
I'd also like to apologise for the delay in getting back in touch, we have been busier than normal.
Are you still having this problem now?
Can you confirm the make of phone you're using?
Have you updated the number in your settings to ensure it's correct?
If so and it's still an issue pop back and we can take a closer look from here.
Thanks.
