Works 1a, top range (with Samsung LTE stick)

I have the device with the Samsung LTE stick from Vodafone - use however o2.
Absolutely easy installation, device automatically finds the correct settings. Then connects automatically. Neither the stick nor the device are Sim-Lock tied - I use it with O2.

The range I find really great, have full throughout the house Auschlag - what more could you want for that price.
