Simba has been quietly improving its roaming experience, and the latest updates are especially useful if you travel to Malaysia often. It’s not just about adding more countries anymore. What’s changing now is the actual quality of the connection when you’re overseas.
SIMBA now roams across major Malaysian networks
A big improvement is that Simba can now connect to multiple operators in Malaysia, namely Celcom, Digi, U Mobile and YES. This makes a real difference in day-to-day use. Instead of being stuck on a single network, your phone can switch to whichever signal is stronger in that area.
If you’ve ever had patchy coverage while crossing borders or moving between cities, you’ll know how important that is. Whether you’re in Kuala Lumpur or somewhere more remote, having more network options simply means a more reliable connection.
YES 4G and 5G support (quietly added)
Here’s the interesting part. While not officially highlighted yet, users have noticed that Simba can now connect to YES on both 4G and 5G.
From testing, YES runs 4G on Band 20, Band 38 and Band 40. These three bands balance coverage and speed quite well, so you get both reach and decent performance when it is in carrier aggregated mode.
On the 5G side, YES is using the DNB 5G NSA setup. In simple terms, it relies on a 4G anchor while delivering 5G speeds. The combination observed is Band 28 together with n78.
In real usage, this setup gives you wider coverage from the low-band LTE and faster speeds when the 5G layer kicks in. It’s not just a “5G icon” situation, you can actually feel the difference when downloading, streaming or using hotspot.
VoLTE while roaming on all 4 networks, you can now call back Singapore for free when you are roaming on VoLTE capable network.
You get better coverage, faster speeds and clearer calls without needing to think about switching SIM cards or buying local plans.
So, if you are heading to Malaysia, the default when you set to AUTO would end you up with CelcomDigi or umobile for higher speeds. If you want to experience wider coverage in some more remote areas, try manual select Yes as it’s 800MHz band does help you to get connected but the speed is much slower with it’s 5 MHz allocation of B20.
