Good for WiFi Streaming, Struggles with Mobile Data
I've been using CyberGhost on my iPhone and iPad for a couple of years. When I'm connected to WiFi, it works really well. I mostly use it on my iPad to watch YouTube and connecting to servers in countries like Albania or Russia means I can watch without ads which is nice and I never had any problems with that.
The only issue I've had is when I'm out and using mobile data. My network isn't the best and in some areas the signal is already pretty weak. If CyberGhost is turned on, the internet sometimes just stops working completely. I tried disconnecting the VPN but it kept turning itself back on. I also tried disabling the Kill Switch but that didn't help either.
After a while it just got too annoying, so I ended up deleting the app from my phone completely. If you've already got a slow or unreliable mobile connection, I probably wouldn't recommend using CyberGhost on your phone. On WiFi though, it's been absolutely fine.
