Works fine. No issues at all. Just you need to use a full-size SIM, not the usual mini or micro. Also, you cannot receive SMS. activation codes on the device.

In my opinion this unit is a total waste of money, it does not work and in my case it has made matters worse.Though the damned thing shows never less than four bars the output does not reflect the reality. Even after installing an outside Arial to try and improve matters every outgoing or incoming call breaks up / cuts off or is so distorted that it renders conversations impossible. You might find it works; but for me it has proved to be money going out with nothing by the way of improved communication coming in, Frankly a mobile telephone on the windowsill is far more reliable than this piece of over-advertised technology.

Device stated it recognised UK sim and had a full signal, but refused to make calls, receive calls, or pick up a dail tone. Don't think it works / Is not compatible with UK networks, despite being described as such.Contacted seller or replied saying I would have to wait as they "needed a rest" !? So opted for Amazon return.
