4G/Wi-Fi calling on O2
09-08-2018
Have new S9+ on O2 network, bought thru Carphone Warehouse, but phone does not have O2 firmware. Can I have firmware modified to enable 4G/Wi-Fi calling?

@M15 is just plain wrong. There is specific O2 firmware required for 4G/ Wi-Fi calling, so the reply was of no help.
