Have a 1 month old iPad Air signed up with Telus data plan in a Canada.
Despite getting 3-4 bars of LTE I often have trouble loading a web page in safari. Only when I disable LTE in settings and use 3G do the pages load up.
Sounds like you don't get very good signal where you are. I get the same thing with AT&T and Verizon at my house and get edge speeds or no data. It gets better in the middle of night.
T-Mobile is the only one here who can get me actual LTE speeds.
