Do I need to buy a new eSIM for each trip?
Depends on provider: Ubigi and MTX Connect offer truly reusable profiles where you install once and only purchase new data plans. Saily allows destination switching without reinstallation. Airalo, Nomad, and Holafly typically require new eSIM profiles for different destinations, though the process takes only minutes. Reusable options save hassle for frequent travelers.
