Using an Aircard 810S in the USA, if it was purchased in Europe ?

[AnnCD]

I purchased an Aircard 810 in France for use in France.

Can I use it on holiday in the UIS ? 

I understand the systems may be different and that it will not work if I use a sim card bought in the US

Correct ??

Thank you

Are you planning on using the sim from EU in the US? That'll depend on whether your ISP supports international data.

Thank you for your reply.

So it depends on the French ISP ? or the US ISP , or both ? 

Question :  even if I buy a US sim-card with US data, I understand that the netgear device, which I presume is 

a GSM device, will not work with a Verizon sim card because Verizon is only CDMA. Correct ?

My ISP is Orange which partners (I think) with T-mobile in the US. 

NB I am not a geek. Merci !

Looks like in the US its a sprint device. Not even sure how to activate it anymore and it was 1st generation 4g. Your speeds on it aren't going to be that great. You'd be better off to use an unlocked phone and hot spot it using something like mint mobile or google fi.
