Many Redmi 2/Prime users was getting 3G problem on their Airtel network. On Redmi 2/Prime,they were easily able to use 2G internet or network but when they moved to 3G mode,the network goes onto,”No Service” or “Emergency call only”. They were not able to use Airtel 3G.
After getting too many responses on Xiaomi forum,I contacted to Airtel & told about this situation.
Earlier,we chated little on facebook. Later they called me & told me that there is no problem from their side & no bandwidth related issue. They also said me that Redmi 2 Prime is very good smartphone.
I again message this problem by showing screenshots & finally it worked.
Now,I’m able to use Airtel 3G.
