My employer pays me an extra $35 a paycheck which i pay tax on. i use my personal phone but i need unlimited minutes + data for work. Can i claim this as an expense?

I have read articles stating that i can only claim itemized parts of the bill but i chose to have a cell phone plan that gives unlimited minutes and texts as well as 5gb of data so there is no itemization to separate, especially on data and there are no additional charges each month.

Can i just claim the $35x24 at the end of the year and if i do, do i have to submit the pdf monthly bills as the receipt?

My company also pays $150 towards a phone upgrade every 2 years but that amount only covers a small portion of a phone upgrade nowadays so can i claim the remaining amount as a business expense?
