SIMBA's network is built on 4G technology, which means voice calls can only be made using VoLTE-capable handsets supported by our network.
There are many handsets in the market that are 4G-capable but may not be VoLTE-capable. Currently, VoLTE-capable handsets supported by our network are listed here.
Don't have a VoLTE-capable device? Fret not! Stay connected with the SIMBA Voice App to make and receive calls on your SIMBA number whether you're in Singapore or overseas.
