Nighthawk mobile router roaming

I have a nighthawk M1 mobile router which I’ve using without problems in my home country (UK).

However I am currently in France on holiday with on overseas data plan from EE and the router when switched on says Roaming Data Disabled and never gets beyond the orange flashing lights.

ive opened the Netgear Mobile app but it can’t find the router and won’t accept “admin” and “password” to login, nor does it offer me a “forgotten password” option to reset it.

i then try to access settings via the https route but that tells you log in via the app which I’ve already tried and failed.

ive seen lots of chats online about possible fixes but I haven’t found one that works yet - very frustrating.

Would really appreciate some good advice
