Hi.

I've just joined 48. Always had 4G with previous carrier and 5G where possible. However, since using my sim today, I have only had 3G. I'm using iPhone 12. I've reset network settings, turned iPhone off and on. Taken SIM card in and out. Voice & data is set to LTE and even when I choose 5G on.. still nothing! I've been on live chat and they haven't assisted me what so ever. I've updated all APN configurations also. Any advice welcome please !!!
