The main operators in Malaysia are Maxis, Celcom, Digi, U Mobile and Tune Talk and as a traveller or tourist, you probably wouldn’t need to look for other operators. 2G and 3G coverage is very good in populated areas in Peninsular Malaysia. 4G coverage tend to be limited to major towns and cities. Coverage in East Malaysia (Sabah and Sarawak) tend to be very patchy outside of city centres. Celcom tend to have better coverage in rural areas of East Malaysia.
Here are some ideas of what i may recommendation:
Celcom is the largest provider in Malaysia and offers good 2G, 3G and 4G/LTE services on a GSM platform. Its prepaid SIM card is called “Xpax” and can be picked up for free, although prepaid SIM card plans will have to be added before use. Celcom kiosks are dotted around most towns and cities, and also at the airport. Credit can also be purchased at most retailers around Malaysia. All SIM sizes can be purchased, although some will have to be cut down to fit the nano or mini size.
All prepaid SIM cards are sold under the “Xpax” brand name. A good option is the “Xpax Turbo” pack, which costs MYR10 and comes with MYR6 of credit and 200MB of data, valid for 7 days.
The following data packs are also available, listed with their prices and activation codes:
7 days 2GB RM10 *118*2*2#
