The evolution of travel connectivity
Prepaid SIM cards dominated travel connectivity for 20 years. They remain excellent in price-competitive markets: Thailand, Vietnam, India, Philippines all offer extraordinary value on prepaid SIMs from local carriers.
eSIM does not make prepaid SIMs obsolete β it makes the purchase and activation process digital. The underlying technology (carrier network, data pricing) is similar. The difference is in the experience around it.
The dual-SIM sweet spot
Many experienced travelers use both strategically. Keep your home SIM active for calls and 2FA. Install an eSIM for data in high-cost markets (Japan, Europe, Australia). In price-competitive markets (Southeast Asia), buy a local prepaid SIM and put the home SIM in a secure pocket.
