My 2 cents, hoping it helps for those with a similar setup as mine:
I have an iPhone 12 and run a dual sim (1 e-sim, 1 sim card). I could only open Eufy’s video stream via the mobile data of the sim card and not via the mobile data of the e-sim.
Tried a lot of different settings and nothing helped.
TIL that turning off the sim card line enables me to connect to the video stream using mobile data from my e-sim.
Not really a fix, but hope it helps.
I do think this is an issue caused (and therefore fixable) by Eufy, since I have 0 connectivity issues via mobile data from my e-sim and I use a lot of domotica solutions that I call/use via mobile data.
Also, Eufy throws an error stating that I’m not connected to the internet, which is false since I have an active internet connection in those cases.
not really motivated to push a ticket at Eufy reading above how they (not) (re)act on former tickets of this nature. However, if we don’t keep reporting, nothing will happen for sure, so I’ll report it soon.
If they react with new/useful info for this topic, I’ll post it here.
Again, hope it helps some users
