I have recently purchased a Meizu M3 note in India which has 126.96.36.199G firmware version installed. I have BSNL which is one of our state run GSM Services. The problem I am facing is when I insert the sim, All 3G signals are there, however, it says “Cellone(Data Connection Only)”. I cannot make and receive any calls, Not even send and receive any texts. Data connection is working.
I have tried different company Sim Cards, Like Airtel, Vodafone etc. they are working. I have even tried two different BSNL SIM Cards. Issues is same with all BSNL sims. These BSNL Sims are working in Meizu M2 note.
Please let me now anything can be done. It will be really helpful.
