Mobile Phone Bill Sole Trader Question

[Amateur]

I set up as a sole trader a couple months back. I am also registered for VAT. My sole trader business is part time as I also have a full time job.

My question is regarding my mobile phone bill. I use my mobile phone for the "odd" sole trader business call. I am wondering if I am entitled to put my mobile phone bill against VAT for my sole trader business or a portion of it. I reckon 10-15% of the cost of my bill is related to my sole trader business, with the rest being for personal use.

Thanks.

I would apportion the bill and claim the VAT on the 10-15%.
