Hey, I've set up my network and internet numerous times over the years with no issues, however doing it on my Lumia 650 is a bit trickier. APN and MMS are split into two seperate profiles, and a few of the options aren't listed on it that are required in the usual set up guides like this one:
If you have problems then double check the what you did against the instructions. If it still doesn't work then post back with specific details - e.g. screenshots of your settings etc.
Hope this helps.
I am not a 48 employee so if you need to contact 48 support then use option 3 or the chat facility here.
