I don't know why but for me, I life in Munich - Germany and LTE is throughout lower strength than 3g for me. But maybe that's because the telecom 3g network is perfect in munich.
It depends on if the 2600 is used it has much higher speeds but it doesnt have a high coverage level. whereas the 800 has a much higher coverage level but it gives a slower transferspeed.
Maybe the 800 isnt implemented so widely yet in Munich ?
