UK traveller to EU countries …. Roaming

[Royboy63]

Hi Guys

I am considering buying a 

Nighthawk M1 4G LTE Mobile Router

to take in my motorhome for mobile internet whilst travelling.

We will be travelling from our home in UK to the EU

normally France Belgium Luxembourg Germany Switzerland Italy Spain Portugal Greece etc.

before purchasing the item (and spending what is a lot of money for me) I want to know for sure it will work in all the countries I have listed?

I intend buying a ‘pay as you go’ SIM DATA CARD’ in each country and inserting it in the Router.

Will the router work? 

Will it need configuration each time I change the SIM CARD?

Up until now I have been using a MIFI device to do this without issue, as described above, but want to upgrade to the better Netgear solution.

However I don’t want to waste my money if it won’t work in EU!

thanks

Roy
