I have an IPhone 15 plus max. My cell phone speed on what is supposed to be 4G but it’s LTE is between .38 to 2.8. mbps. Verizon can’t figure out why it’s so slow and not showing 4G. Congestion can play a part but still should not be that slow. They suggested I upgrade my plan to 5G unlimited ultra and said that would fix the problem because I would get priority over anyone else so I did as they suggested. Still don’t have even 4G on my phone only LTE and the speed is now between 2.43 to 4.44 which is absolutely ridiculous. So I now pay $40 more a month for still extremely slow speed even though I was told upgrading my plan would fix the problem. Well IT HASEN’T FIXED IT!!!
