Try this:

Go to Settings/More/Mobile networks/Preferred network type

Then sellect WCDMA only (3G), if that doesn't help try GSM only (2G), if that doesnt help then sellect WCDMA (preferred) /GSM, and if that doesn't help try LTE (preferred)/WCDMA/GSM.

Hope that one of these options help you and good luck!
