Is buying a regional eSIM better than switching local SIMs if I plan to visit multiple islands or countries?

For travelers visiting several locations, a regional or multi-country eSIM can be much more convenient than buying several physical SIM cards. It eliminates the need to find new SIM counters each time you move and often provides seamless data coverage across borders. If you expect to visit countries with very different network partners, compare per-GB pricing and coverage before purchasing to ensure the regional plan fits your itinerary.
