Yes, absolutely! We highly recommend installing your Mexico SouthESIM before you even leave home. The smart thing about eSIMs is that your data plan won't actually activate until your phone connects to a local Mexican carrier. This means you can install it, pack your bags, and as soon as you land at, say, Mexico City International Airport, your phone will be ready to go, helping you find your way to that delicious taco stand without a hitch!
