Has anyone bought a mobile phone card at Sabah Airport?

There are several stalls selling mobile phone cards on the first floor of the lobby of Sabah Kota Kinabalu Airport. I usually choose HOTLINK to buy them. The signal is better in Kota Kinabalu. If you want to go to the island, you may still want to buy it. If you want to look for other people's tips, some islands may have better signals with Celcom cards. Some have better digi signals, depending on which island you want to go to.
