Ideally, any handset that supports 4G LTE and VoLTE should be able to support the Reliance JIO SIM card. However, there have been instances when the device did not support it even after having 4G enabled. If you are not sure whether your handset supports JIO SIM or not, Reliance has put up an elaborate list of supported devices from almost all brands on their website. It would be wise to check the list if you intend to use a JIO SIM and planning to buy a new handset.
