No data from carrier, but calls work. Tried another service provider and it works

I recently bought Mi A1 from someone, now that I inserted the sim, I can get calls, but no data service. Is there a way to fix this problem? Without having to change service provider?

Your APN needs setting correctly, get the APN settings from your sim provider and update the APN in your phone settings.

I tried this with no success. Is there something else?
