Mobile data not working I have a Samsung Galaxy J510-MN (Latin American version) which I have bought from Mexico (Android 6.0.1). Now, I returned to Germany and put a German SIM Card (Fonic/o2). I get network connection, phone and SMS function works. But, I can't get mobile data. I do have the card charged and I already got mobile data settings sent to my phone by phonic, but still it doesn't connects.
How can I solve this? Or might it be a hardware problem, e.g. my phone can't receive the frequency they used in Germany?
Have you tried to change the Network connection in settings? If 2G only or 3G only works, then it might be a band problem.
