I have been using Moto G for 2 weeks now. Aboslutley no notable issues till now but for one.
I have Airtel GSM connection in India. And when i am switched to 3G Network, I often notice N/W issues like my calls take time to get connected, 3G Internet goes slow and sometimes when i try to check my balance using *123# or *121*2# , I get this error message - "Connection Problem or Invalid MMI Code".
This never happens if i am switched to 2G Network. Happens only when i am in 3G.
Co-Incidently I had this problem in my older Samsung Galaxt SL i9003 too.
Kindly let me know if anyone else in India is facing this issue or can it be because of my device or my SIM.
P.S i happened to cut my normal SIM to Micro Sim to fit it into Moto G and my SIM is approx 4.7 years old.
