In the past, mobile phones had to "drop down" to older 2G or 3G networks to handle a voice call, even if you were browsing on 4G. VoLTE (Voice over Long-Term Evolution) changes that by allowing your calls to travel over the modern 4G network.
As older 2G and 3G networks are being phased out, VoLTE is becoming the essential standard for staying connected.
The Key Benefits of VoLTE
Crystal-Clear Audio: Enjoy "HD Voice" quality. Calls sound more natural and background noise is significantly reduced.
Faster Connection: Your phone doesn't have to switch network modes to place a call, meaning call setup times are almost instantaneous.
Multitasking: You can use 4G data and voice simultaneously. This means you can browse the web, use GPS, or check an email while staying on a live call.
Better Indoor Coverage: VoLTE frequencies often penetrate buildings better than older 3G signals, leading to fewer dropped calls indoors.
VoLTE on the OnSim Network
OnSim fully supports VoLTE across our entire network. However, to benefit from it, you must meet two requirements:
