I-Phone 12 very poor cellular reception versus I-Phone 11
Temporarily in an area with no Wi-fi so relying on cellular via BT. I-phone 11 has worked perfectly for calls and data and always shows four bars and 4g.
Got new I-Phone 12 on Weds and also shows 4 bars and 4g but no calls or data available. BT have kindly replaced the sim which activated today and I still have the same problem. Phone is a very pretty paperweight.
Anyone got any ideas why newer model won’t work where older one does?
