Check to make sure your mobile data is turned on. Contact your service provider to make sure it's not on their end. Ask them to verify what your APN settings should be.

Welcome to Android Central! Tell us the exact model number of the phone (in Settings>About Phone>Model Number), so that we can see if that model supports Amaysim's network bands.
