Has anybody lost their internet connection after a 4G upgrade in their area? I use wireless mini modems (dongles) running off a desktop pc and large screen. Being disabled, it is much easier this way for me. In May 2021 a 4G upgrade was done, and now my dongles have lost connection. Have rung the telcos, and they just want to pass the buck. Have dongle frequency bands been discontinued? Noone is saying anything. My dongles are functioning good - no faults with them. But keeps coming up as 'No Service'. Have to post this message on a small screen mobile phone. Please, does any one know? Thank you.
