Hello
I’d like to ask, a smartwatch with LTE that doesn’t have an option to set a preferred mobile network i.e. to 3G or 4G and can switch between 3G/4G, if it has a 4G esim activated in it, but VoLTE is not supported by the network, what exactly happens when it’s used for data, sms, calls? Will it switch automatically to 3G? if no 3G is available then does it switch to 2G (even though the watch might not support 2G) automatically?
Thank you

VoLTE is voice over LTE and only used for voice calls. If VoLTE isn’t available then your device will do a CS fallback to 2G or 3G for calls. It’ll switch to 2G if there’s no 3G or 4G. If it’s not supported you’ll have no signal
