Answer
Try the online Tweakker configurator first. If that works, then that's great, you're done!

If your specific phone model is not listed, then try choosing one that is "similar," as that may also work.
If, as happens to many people, it does not work (e.g., never sends any configuration settings to your phone), then you will need to configure the settings manually, so read on...
Make sure that your plan is active and you actually do have a data allowance through your plan or a data add-on.
Dial *100*8# to check your data allowance balance.
Handy short-codes
Make sure that your settings match those below:
APN: 48months.liffeytelecom.com
MMSC: http://mmc1/servlets/mms
MMS Proxy: 10.1.11.19
MMS Port: 8080
MCC: 272
MNC: 11
APN Type: default,mms,supl
It that APN Type doesn't work then try:
APN Type: *
Leave all other fields blank/not set (including Authentication type).
Make sure that data roaming is enabled.
Make sure that data is enabled.
If you configure these settings and they still don't work, then please DOUBLE CHECK that you did not make any mistakes, e.g., some people have entered 48.months.liffeytelecom.com instead of 48months.liffeytelecom.com etc. The settings must be entered EXACTLY as specified above.
If you already have internet/APN settings but they are different to those above, then reconfigure your settings so they match those above or delete any existing APNs and start again and add the 48 one anew.
If internet/data still does not work after configuring the settings correctly then try powering off and on again and maybe manually scanning for networks and connecting to 48.
If internet access still doesn't work, contact 48 Customer Care for assistance:

We hope this helps!
How do I add/configure an APN on my phone?
You need to check the documentation and user interface of your phone for specific instructions.
However, on most Android phones, the process is similar, although there may be slight differences in how to navigate the menu options to get to the right place and slight differences in the options that can be configured.
See here for an example of a general guide for Android phones:
http://www.androidcentral.com/what-apn-and-how-do-i-change-it
Similarly, for iOS, the specific menus/options may differ depending on the phone and version of iOS. But this is what Apple have to say about it:
https://support.apple.com/en-ie/HT201699
And here is another third-party guide (which may or may not be for a specific version of iOS):

If necessary, please Google for specific instructions for your phone.
A note about personal hotspot setup on iPhones
Once you have your internet APN set up and data/internet access working, you can also use this connection as part of a personal hotspot (this will probably use up your data allowance more quickly than "normal" internet access, so keep an eye on your quota and make sure that you don't breach the fair usage limits).
This is generally straightforward on Android (and Windows?) but Apple sometimes makes it more difficult on some iPhones/iOS versions for some reason...
Some people find that their iPhone / iOS 8 does not show the personal hotspot option, in which case, the following workaround may be required:

Please note:
- At around 1 minute into the above video, he has Personal Hotspot > APN = gadget. Enter 48months.liffeytelecom.com instead.
- At around 2 minutes into the above video, he has Mobile Data > APN = internet and also Personal Hotspot > APN = internet. Enter 48months.liffeytelecom.com instead.
