not getting some of my text

[daftlad2003]

My problem is I am not getting all of my text messages one in particular and my mate thinks im ignoring him.he does live about 150 miles away in Doncaster and has 2 phones one on o2 and the other on Tesco he uses both but 90% of time I do not receive his messages we have to chat on wattsapp

So for starter I have a galaxy s8 plus

I have done a factory reset (pain in the*****)

Cleaned the sim

Checked the message centre number

But still have problems probable next step is for me to change networks see if it solves problem

Any help would be great thanks
