Question [Q] Phone getting switched off when i switch on data connection

I am using Micromax a50 ninja. My phone gets sudden switch off whenever i switch on data connection. I thought it may be rom problem and changed to almost all Custom Roms like jetmod 3.0, lewa, espire ios, appo but still the problem is not solved.. the frequency of sudden switch off is more in jetmod > stock rom > espire > appo but problem not solved.. what might be the problem and solution?? please if anyone knows about it plz let me know the solution...
