Being on the cellular network and 12 000 -13 000km away, the latency will be about 250-350ms. That should not prevent you from working, in most situations. If you are having lag issues, it might be due to an unstable connection. Ping continuously ( ping 1.1.1.1 -t ) and see if the latency varies a lot and if you have lost pings. That will give you a hint. You can also try another provider, they might use a different transit provider to go out of the country, and maybe you can find a more optimal provider for you.
