Will my home SIM incur roaming fees in Southeast Asia when using EastESIM?

When you're actively using EastESIM for your data needs in Southeast Asia, your primary home SIM (e.g., from the US, UK, or Australia) will not incur data roaming charges. This is a key benefit, especially when exploring countries like Thailand, Indonesia, or the Philippines where local roaming rates can be high. However, it's vital to remember that your home SIM might still charge for voice calls or SMS if you don't adjust your phone settings to disable international roaming for those services. We always recommend checking your home carrier's specific international rates for calls and texts to prevent unexpected costs.
