Hi support, recently switched over to a 4G plan and phone is showing a 3G connection and has connection issues when making and receiving calls. I don't think it's throttling, using an Iphone 11 so need some help here. Could it be the SIM card or an Iphone setting? Please advise, thanks.
@RPappas In addition to what @Outdoorsman said to do. Another thing is that iphone's allow you to use just 3G or LTE and if there is not LTE it goes down to 3G. Go to settings then Cellular then Cellular data options and in voice & data select LTE. Another thing is that in order to get the speed of LTE (LTE is another name for 4G) is that it takes 48 hours after switching to the 4G plan to actually get the speed.
