When using an EastESIM multi-country Asia plan, your data usage will be routed through the eSIM, effectively preventing your home SIM from incurring data roaming fees. This is especially beneficial when hopping between countries like Singapore, Malaysia, and Thailand. However, your home SIM (e.g., from the US, UK, or Australia) may still charge for calls or texts if you don't adjust your phone's settings to disable roaming for those services. Always check your primary carrier's international rates for voice and SMS to avoid unexpected costs, even with EastESIM handling your data seamlessly.
