You mean 10GB?
And €5 for a SIM assuming you don't want to buy a phone from them?
Edit: and Tesco don't do 4G according to their website:
I don't see how that screenshot indicates that you have 4G.
H+ is capable of those speeds and it's not 4G.
Maybe you can clarify why you think that you're getting 4G?
My understanding is that 48 simply don't support 4G/LTE at the moment so I can't see how you would be getting it.
Hope this helps.
Edit: sorry I now see that the screenshot shows a 4G icon.
That's very odd and doesn't make sense to me.
I must ask 48 support and report back.
I wonder if it's possible for a phone to misreport the data mode?
What does it say under Settings > About phone > Status (or similar - sometimes the specific menu path is different depending on the OS version)?
What make and model of phone and operating system version is it?
OK, so it looks like the signal type icon for 4G in the status bar is probably wrong and you are getting H/H+ after all.
I asked 48 support and they said there's absolutely no way that you could actually be getting 4G on 48 as they simply don't support/provide it.
What make and model of phone is it?
Sorry - I overlooked the fact that you said that you have an LG G3.
I can't see any evidence of any LG G3 or Android Marshmallow bug whereby they show 4G when actually on H/H+ but I can only assume that this is the case here and somehow it's showing 4G when it's not actually on 4G.
