LTE was working fine since mid summer. Now, since last week it's been nothing but 3g. It happened one afternoon and I figured it would go back to LTE like it always does when it suddenly goes out. Now it's intermittent Roaming too.
I've refreshed network, talked to support, verified my SIM, updated profile, and physically taken out the SIM to clean and reinsert it. I've given my cross streets and was told there's no problem with towers. EVEN ON 3G SERVICE CUTS OUT FOR MINUTES AT A TIME.
