Hi @Helsh,
Thank you for your post and welcome to our community forums. We're here to help.
I'm so sorry to hear you're experiencing some issues with your mobile service recently. I've just checked the post code you've provided using the Service Status checker, and it states that there's a known issue with a mast in that area that's being worked on.
I do apologise for the inconvenience that this causes for you, but I assure you that we're doing all that we can to get this sorted out ASAP. Keep us posted.
Thanks,
