Will my home SIM incur roaming charges in remote Asian regions if I use EastESIM?

When you're utilizing your EastESIM for data, your home SIM card (e.g., from a US, European, or Australian carrier) will not incur data roaming charges. This is particularly important in regions that might be considered more remote or less frequented by international travelers. However, it's a common misconception that all roaming is disabled. Your home SIM could still charge for incoming or outgoing calls and SMS if you haven't explicitly disabled roaming for those services in your phone's settings. Always check your home carrier's specific international rates, especially when exploring less connected areas in Laos or Cambodia.
