Cannot receive calls but can make calls on my tablet HCL ME Y2

Question

I recently bought a HCL ME Y2 tablet with Android 4.0.3 (Ice Cream Sandwich) installed.

It has a SIM slot and when I use the Phone dialer (the blue phone icon app), I can make calls over GSM but when someone tries to call this number, the phone vibrates for less than a second while I hear a single ring at the calling phone and immediately after I get the message that the phone is busy.

I cant even sent SMS / receive SMS on the tablet.

I Couldn't find any solution to this, any input?

Answer 1

I had the same problem and resetting the device fixed the issue. Give that a try.
