SIM & eSIM Cards
Buy eSIM before you arrive -- Hotlink
Hotlink is the prepaid service of Maxis - the best premium cellular network that corporate users go for more than any other networks.
Good news! You can use passport to open an account and buy the eSIM before you arrive in Malaysia.
None of these links are affiliated. I earn nothing.
If you need Physical SIM cards
Buy at the airport after deplaning:
- CelcomDigi High Speed
- Maxis/Hotlink
Disable 5G ASAP
In Malaysia, while the telcos mostly operate their own physical infrastructure for 2G 3G 4G LTE, none of them own their own 5G network. There is only 1 real 5G operator -- DNB, and all the telcos lease the 5G coverage from DNB alone.
As such, 5G network is usually overcrowded. If you are on a better telco like Maxis/Hotlink and CelcomDigi, disable 5G in your phone and just stick to 4G most of the time.
