Yeah I have an unlocked Nokia that I forgot to pack. Otherwise, I could slip the SIM in there to check.
I could have used the phone to input the PIN the first time I fired up the Mifi with the SIM. Had to go back to the shop and ask them to activate the PIN for me, which they did.
But disappointing that the Swisscom portal does not display this info, at least not where I could see it.
Maybe in a few years, unlocked LTE devices which support a lot of LTE bands will be cheap. Otherwise, what I have is good for now.
This device is intriguing, for battery life if nothing else:

But it's locked to one network so maybe the vendor will make unlocked models of similar devices.
