Travelling to Aus and have bought a roaming add on

Such a silly question but in order to use the additional data etc I've bought do I have to switch roaming on on my phone? Or does the data just add onto my usual contract and allow me to use internet and socials/apps as usual? Grateful for advice!

It should just switch over automatically Parkie56 however if you have any issues accessing data you can update your data settings, details below.

If you have problems with accessing the internet while abroad, please check your data settings and manually set them as below:
APN name: uk.lebara.mobi
Username: WAP
Password: WAP
Restart your phone after updating data settings.

Thanks Martin. That's helpful.

No problem Parkie56
