Not able to use LTE/4G on iPhone XS.
I just changed my old SIM because of its old age and it was working fine on LTE. But now with the new SIM I only have access to 3G. All settings are the same and I have my same cell number, but not connecting to LTE/4G network anymore. What can be the issue? How can I fix this? I have already done a reset of the APN.
iPhone XS, iOS 17
