What exactly do you mean by "slow data/network connectivity issue"?
Is it slow data or loss of network signal (bars) altogether or both?
When was it working ok last?
Are calls and texts working ok?
Are your APN settings configured correctly?
Have you tried gently cleaning and reseating your SIM in case that helps at all?
Do you know anyone else in the same location on 48 to check what their experience is?
Can you try your SIM in another unlocked phone to see how it works there?
Maybe try a replacement SIM in case your existing SIM has developed a fault.
If you need to contact 48 support about this then see the links in my signature below.
