At the moment I only use the plug for my laptop. Can I also connect my cell phone to it?
The problem is it's already encrypted but I don't know how?
For this you can use a WLAN access point (WLAN AP, sometimes also called "WLAN router").
? Can I not connect my cell phone to the powerliner?
The repeater you mentioned is not WLAN-compatible. So if your cell phone does not have a LAN port (which it does not have) you can't use it to get your cell phone onto the Internet
If your smartphone supports OTG, you can also buy an Ethernet OTG adapter. But it may be a bit impractical if the cell phone is always on the cable…

The problem is that your Powerline adapter itself is not WLAN-capable, but only has two Ethernet connections.
You could recommend an inexpensive good repeater our is stupidly overheated and does not always work

Powerline is a technology that has become obsolete because it can disrupt DSL connections. If you have a router from AVM (Fritz! Box), then some of its mesh capable ones. The 2.4 GHz thing. So costs 40 euro.
The 1260E Powerliner has Wi-Fi:
