Probably not. It should still be usable with the test part but it can’t be guaranteed you won’t get hassle from some staff if their device can’t read it.

If you haven’t already added your pass to the phone, do not. It can only be on one phone at a time and if you have added it already but you decide to put it on a new/replacement phone you will have to apply to Interrail customer services to have it removed from your current phone.
