Where is the sim card of my sph-m540

If the vibration works the circuit is working OK. All what can be done is to reset the phone , remove battery and reset, check for any corrupt files on the memory card. Now open settings, tones and check the default settings. check tone set and tune selected. Now if there is no result the ringer might be open and faulty. You can check the continuity to confirm , if so replace.

No, Samsung SPH-m540 Rant doesn't have a SIM card.It's a CDMA phone. You'll have to conatct your service provider to activate a CDMA phone.

Try & press the reset button. It is near or under the battery. You night need to use the end of a paperclip. If that fails see your provider.
