Not ringing for incoming calls (Micromax Canvas Tablet P480 - Android 5.0.1)

[AC Question]

I have Micromax Canvas tablet P480, using Android 5.0.1.

When screen is locked it does not ring for incoming calls. Why? (But rings when the screen is unlocked) Due to this I am missing many calls. Anything I should change in the settings? or is it a bug? I tried all the audio profile setting as well as notification setting, including interruptions for priority calls.

Please let me know if you need any other information.

Any suggestions will be greatly helpful. Thanks!

Welcome to Android Central! Are these calls coming over a voice signal or wi-fi? Does this tablet have a SIM card and the ability to make regular phone calls?

Are there any power saving modes turned on?

Thanks for your reply.
1. Voice signal not wifi
2. Yes has a SIM card. The issue is for regular calls received.
3. No, power saving mode is not turned on.

Ok, and just to be clear--the tablet's SIM card is used for phone calls, or for mobile data only? In the US, LTE-enabled tablets don't have telephony--they use the SIM for 3G/4G mobile data only. The specs on your tablet mention that voice calling is not supported on either SIM: Micromax Canvas Tab P480 price, specifications, features, comparison

Can you actually place a call to someone else using the tablet?
