Yes I am on SUNRISE with it. I have been using it since December 2017. Very disappointed with the battery. I took it for its high capacity. And in normal professional use, it doesn't last more than 24h now :-(
Hi JoeAnn,
As the phone is already double SIM, I would say that it is not SimLocked, so it's available for many networks.
(Mine is also double sim, and I have a Swisscom prepaid in it and a Salt abonnement, and it works perfectly with both networks)
Best.
