Bit of an odd requirement

Looking for a radio for my dad who wants to listen to an international radio station outside. I want to have it setup where he can turn the device on / off and select a pre-configured station via the device.

The station is not available locally on AM / FM / DAB so it would need to be Internet enabled and Wi-Fi is probably out of range leaving 4G / tether to a mobile phone maybe the only way.

Couldn't find anything obvious that would meet this requirement and was wondering if anyone might know some good options? Thanks
