Hi everyone, 

I've asked two 48 agents about this, but no one seems to have a proper solution so far, I was wondering if anyone has had a similar issue and how they fixed it.

I got a new replacement SIM 5 days ago, and my mobile data, along with everything else was working perfectly. 

I then got a message from 1749 (48) with new browser settings, which were installed, and then my mobile data stopped working. 

From the icons on my phone, I can tell that there isn't an issue with sending data, but there is an issue receiving data. When connected to Wi-fi, there's no issue. 

I've switched it off and on again, I've tried "Flight mode", I got them to send another configuration message and I've checked the APN settings about 20 times, but it's still not working. 

My phone is a Samsung Galaxy S4. 

If anyone has any other useful ideas, that would be great!

Thanks in advance.
