Hi I'll be in Europe for 2 weeks and I'd like to Roam on an eSIM if possible. If I get an eSim Data Only (or NanoSim with Voice/Data) would my iMessage/Whatsapp/VVM all jump to the active line? I was thinking of going to disable the local cellular carrier completely but keeping the sim inside so it detects the number? Please advise. I'd like to figure this out before I leave.
