multiple nrf9160 do not work

[kamacode]

I am using the board with MQTT simple software

when I am activating one a signle EVB, it works well

however when I am activating on two board in the same general location (100 meters from one to another) only the last board connected gets an IP

I think that the network provider allowes for only one device to work in a certain hexagon

1. can that be? seems very strange 

2. how can I verify \ debug that ?

Hello,

do you get any error codes? What is returned from getaddrinfo()?

managed t oresolve, it was the network operator limitation in that region
