ByteSIM is an eSIM provider that can help you stay connected when you're on the go. eSIM — or embedded SIM — is a digital SIM card that's built into your device and can be activated virtually. (Most flagship smartphones support eSIMs).
For a limited time, you can get 300GB of high speed data across Southeast Asia for just $0.1/GB via coupon code "TOMSGUIDE". That's one of the best prices we've seen.
Based in Hong Kong, ByteSIM was founded in 2022. It provides high-speed data across 200+ countries and regions with flexible plans. Locations include South Korea, Taiwan, Singapore, Indonesia, and more.
Because it's an eSIM, there is no plastic SIM card involved. Instead you choose your plan online, download a mobile carrier profile, and connect to a cellular network when you arrive at your destination.
Plans can combine fast, low-latency connectivity with calls, text, local numbers and hotspot sharing. You can even access 5G connectivity if it's available in your area. ByteSIM users are dependent on local telecoms for infrastructure, so your speeds can vary. For example, 5G connectivity may be more accessible in cities, but harder to come by in rural areas.
If your existing carrier plan isn't particularly travel-friendly, you can get an eSIM like ByteSIM with more affordable international options. That way, you can continue using your current phone as normal without interrupting your existing carrier plan. Plus, you con't have to worry about keeping track of multiple SIM cards as you travel.
