No data roaming!

I use a Motorola G34 5g phone.
Took up Lebara a few months ago from O2. Went to Croatia last week, and had no option to turn data roaming on? Only mobile data. Any ideas as to why this would be please? Thanks.
Sorry......OK Found the answer. Me being an idiot!!

Can you share how you fixed this Giuliaphil just in case other community members are experiencing a similar issue. Thanks!

I didn't dig deep enough into my settings. I could not find the turn on data roaming, but went into sims and then saw it amongst other options.
