The LTE coverage in my town was awesome when it was first introduced, but now it can slow to a halt many times during the day. The XLTE didn't seem to help it at all. It is completely frustrating to have data hang. I've contacted technical support and it was acknowledged that there are usage spikes during the day which affect performance. I was told there are no plans for improvement.
Is there any way to get the issue escalated? What can be done?
