download ufo vpn mod version from Ocean of apk v2. 1.1 specifically. after that install and click on call of duty mobile Canada or Australia before launching game. I recommend that you use Canada since its very fast than Australia. if it helps please forward it to others. don't update the app or it will stop working. it works without ads even on non rooted phones like my s7 edge snapdragon. try it guys.
