This device variant is not suitable for operation in the European Economic Area (EEA)! We recommend  

using an AT&T SIM card to use the 700-875-LTE11/61 in the United States. The required frequencies are  

supported for the network operator Verizon, but this operator refuses to establish the connection because  

only approved devices are accepted in the Verizon GSM network.
