I am trying to make a reservation for a train from Cannes to Barcelona-Sants and have been unable to make the reservation online since it is not domestic and I cannot get through to the international number. The route is July 14 12:01 Cannes to marseille st charles (TER17486). Then marseille st charles at 17:49 (TER76562) to Nimes pont du gard. Next, nimes pont du gard to Barcelona-Sants (TGV9715) (17:49-21:25).
My issue is I cannot get the TGV9715 booked and I am wondering if anyone knows how to fix this issue? Online it says the first two trains do not require reservations so my understanding was that I could just use the QR code given in the app to board those two trains.
I have tried the SNCB website for TGV9715 but since it is a domestic route it will not work and the number given is not working with my phone. If anyone has any suggestions I would really appreciate it as I don’t know what to do and most places I have tried to ask aren’t familiar with eurail and will only let me book for the full fare cost.
