Short answer: No, if you are visiting multiple countries on a single trip, you do not need to buy a separate SIM card for every border you cross.
By installing one regional or global eSIM before you depart, your phone automatically switches to a supported local network as soon as you arrive in a new country. This eliminates physical SIM swaps, long airport queues, and roaming fees.

For itineraries that span multiple destinations, such as traveling through Vietnam, Thailand, and Cambodia, or hopping between France, Italy, and Spain, a single regional eSIM keeps your connection continuous across your entire route while eliminating SIM swaps and multiple local registrations. You purchase the plan once, scan a single QR code, and enjoy instant data everywhere included in your route.

While regional and global eSIMs offer maximum convenience, individual country plans can still be the better choice under specific circumstances:

| Asia-Pacific eSIM | 15 countries (Japan, S. Korea, China, SE Asia, Australia, etc.) | 500MB–3GB/day, fixed 3–50GB, or Unlimited | 1 to 30 Days | From $3.50 USD |
| Global eSIM | 76 countries across Asia, Europe, Americas, Africa & Oceania | 500MB–3GB/day, fixed 3–50GB, or Unlimited | 1 to 30 Days | From $2.90 USD |

Yes. As long as all your destinations are included in the plan’s official coverage list, your phone connects to local network partners automatically as you cross borders.
You can install a separate, short-term eSIM plan specifically for that leg of your journey. Modern smartphones store multiple eSIM profiles simultaneously, allowing you to toggle between them easily.
For short or multi-destination trips, regional eSIMs are generally cheaper and far more convenient. For an extended stay in a single country, purchasing an individual local data package usually yields better per-gigabyte rates.
