Asus Zenfone 8 Mobile Data Connectivity Issues
So, just a few days ago I've purchased a brand new Asus Zenfone 8, but I'm already thinking of sending it back, because I've got incredibly frustrated over what's going on with mobile data connection.
Basically, the issue is, as follows:
Whether I'm in 4G or 5G mode (I use 4G mode mostly, since I deem 5G one quite unnecessary), once I leave home (and I don't have access to Wi-Fi connection), on the one hand the phone keeps showing me that I have 4G (or, optionally, 5G connection) on the right side of the screen; but on the other hand, on the left side of the screen, I keep seeing a message that says 'Mobile Data - No Internet'.
Since I had no problem whatsoever with mobile data connectivity on my old Sony Xperia XZ2 Compact phone, it is therefore evident to me that it is a device, rather my phone provider (O2) problem.
I have tried resetting 'Wi-Fi. mobile & Bluetooth', but to no avail: the issue persists in any case.
Can anyone, please, help me out with this problem, before I am forced to return the device?
Many thanks in advance!
