Is there signal on the marine-park islands and up Mount Kinabalu?

The islands nearest KK, like Manukan and Sapi, have some coverage, but it thins on the outer reefs and boat rides. On the Mount Kinabalu ascent, signal drops sharply once you climb above the park HQ.

Does the same eSIM work in Kuala Lumpur and the rest of Malaysia?

Yes. It's a single national Malaysia plan covering both Peninsular Malaysia and Borneo, so the same eSIM works in KL, on a Kuching side-trip and across Sabah. One allowance covers the entire country.

Good to know in Kota Kinabalu

For a sunrise island-hopping trip from Jesselton Point, book boats and marine-park fees on data first — signal on the outer Tunku Abdul Rahman islands is patchy, so screenshot your return time and download offline maps before you sail.

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Great for longer or open-ended trips

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.
