Xfinity mobile - Lost signal while traveling to Europe

Hi !

Wondering if somebody else is noticing the same issue. I'm traveling through Europe and my 2 Xfinity mobile phones worked just fine. I was in Italy 2 weeks ago and it was working OK. Then I went to France for a week and both phones stopped working. I thought it was a problem connecting in France, but now I'm back in Italy and both phone are no longer working. Was there a recent APN change or something changed mid October 2023 ? 

Any help to get my phones working again would be appreciated as I cannot call support. Both phones use Android, (11 & 12)

Have a nice day
