Best Residential Proxy for Instagram?

Hi friends, relatively new here... I'm starting M/S... I know many say 4G is the best but I can't afford it so I'm going with the 2nd best solution... What do you recommend? I won't be doing many actions daily, around 40-50 per account

No matter how many actions you optimize your account(s) to take, 4G mobile proxies, that too having the ability to rotate are absolutely necessary. Otherwise, you will keep getting frequent blocks and flags which is a loss.
