I can't turn on data and also I don't have mobile network

The thing is that yesterday I restarted my cellphone because the apps were stopping, so when I turned it on again the signal bar is showing a red cross and also the data is blocked, there's no way to turn it on I made a factory reset and a hard reset and still not working. What should I do? I have an LG L70
