Home Internet and personal Cell for Single person MI LLC for IT consulting

I am a single person LLC in MI with a focus on IT Consulting and use my home internet and personal cell phone.

 

How much is reasonable to deduct?

Would the increase from basic internet to a higher tier given I need video conferencing.

 

For my personal cell, I have a 5-person family shared plan. Is it reasonable to deduct 50% of 1/5of the entire bill?  I think that would equate to about $10 per month.

And for these, should I just submit a personal expense report to my LLC and pay based on that?
