I have just moved over from EE on a 4G LTE plan to Virgin 5G on an iPhone 12. The sound quality compared to the EE network is dreadful and not as clear. Is this because it’s not using a 4G LTE network on virgin? I have forced LTE on the iPhone but it’s still the same, saying the network doesn’t support it. Will it support it in the future? as it’s a little disappointing.
