Roaming Mobile data setting for iPhone XR

I’ve changed sims from Vodafone to lebara.
The data settings are still set to Vodafone.
I’m going to Greece soon do I need to change the settings for the free 30gb roaming there.
i want to still be able to call and text the uk from Greece whilst I’m away and use my mobile data too.

I’m wondering the same .. it’s been asked before but no answers received
it does say to set as uk.Lebara.mobi and WAP
I’ve not used it yet so not sure though . Will be annoyed if it doesn’t work when I go away to Spain on Sunday

I am currently in France and phone is working perfectly, I also changed last week from Vodafone to lebara. As long as you have done the above settings uk.lebara.mobi and the country is in the free category, then it should be fine

I am going to Turkey next week and will need the roaming add on. Have checked and like said above my mobile data settings are still set to Vodafone though I moved across from them six months ago. Checking the APN settings for that there seems to be lots of values set.
I guess I just create the Lebara one on the site with the three settings given eg Internet, wap and wap and fingers crossed it will be fine.
Can't see any other way to ask and get a response other than on here?
