Call ends automatically

Hello everyone.I'm facing a serious problem with my phone,call ends by itself automatically after dialing and Im not getting any incoming calls.This problem exists for few days and then gets rectified automatically.Please help me out

it could be a faulty SIM card or an intrusive app, you could try a new SIM card and/or repair your phone with PC Companion or SUS

taskillers

task managers

antivirus

ram apps

battery apps

booster apps
