Dear Ladies and Gentlemen, Thank you for taking the time to write to us. However, we can understand you perfectly and we are really sorry. We would like to inform you that Swisscom is a Swiss network provider. Currently, 5G does not work in Switzerland because we do not sell the devices there and we do not have any collaboration with network providers. We ask for your understanding in this matter. If you have any further questions, please do not hesitate to contact us. We are always here to help you. We wish you a nice weekend! With kind regards Lorena Cristi ONEPLUS Customer Service This is the answer from OnePlus to my question why I have NO 5G reception. The phone is actually great, unfortunately 5G is probably missing in Switzerland (yet?).
