For SE Asia roaming, it helps to compare coverage and throttling policies. I used Maaltalk for a couple of weeks in Malaysia and Singapore on a regional plan. Setup through their app was straightforward using eSIM QR, and real‑world speeds were consistently good for navigation, messaging, and moderate video. It’s not unlimited true 4G/5G everywhere, but for a 15–20GB travel plan it held up far better than some alternatives I’ve tried.
