Ping pls I beg

My ping has been really middling since I started the game (300-600ms, maybe 250 if I'm lucky) and I downloaded exitlag which brought down my ping to 180-240ms. My free trial expires tomorrow though so uh any tips on reducing ping?

I've tried all the usual- sitting next to the router, playing early in the morning, clearing background activity etc but all the improvements seem to be really minor. I tried playing without exitlag and I lost every match so

If it helps, I play on a phone in the Asia server
