can i activate my pass from USA?

There is no need to activate the pass until just before boarding the first train of your travel. 

Actually i m buying a black friday promo 10 DAYS global eurail pass it says that you have to activate before 1st june 2024 but i am going to Europe in the mid of july.

Its expiery is 31st july 2024 because of promo rates some conditions apply.

But i will be in USA 🇺🇸  in june but i have to activate it remotely from USA. 

SO my question was this can i activate it without being physically present in europe.......from USA 🇺🇸? ......or i have to be present in europe train station to activate this pass?

I believe Al and Anna have answered your question : you will be able to activate your mobile pass on your phone from the USA.

Simply set a reminder.

Its says to start your trip from june 1st.

But my trip starts in july.

Its so confusing.....i dont wana loose money without using itt.

The validity period must start no later than 1 June and will then end on 31 July. You can then travel on any 10 days within that period.

You have to start the promo pass by 1 June, even if you won’t use it until July.

So you lose some of the validity of the pass. 

I’m guessing you will buy the ‘10 days in 2 months’ pass. If you start it on 1June, it will expire at the end of July.

If that suits you, everything’s ok. If not, you can buy a full price pass instead. I bet there will be a promotion in Spring 2024. Probably not a 25% discount though.
