I'm visiting some family in the Eastern part of Oklahoma and my service speed has slowed to a crawl! It says I have full reception of LTE but it's "extended network". My download speeds are at 0.15 Mbps which isn't even enough to open some apps and trying to stream any kind of data is impossible. I've restarted my phone and made sure my roaming data is turned on. I'm having to use WiFi around town in restaurants to get data. This is extremely frustrating...any ideas??
