I swapped BSNL 3G SIM with 4G SIM today. They took Rs. 30
While porting my Voda to BSNL 3G last July something went wrong (I inserted both new & old SIM at the same time), so network didn't came on any.
Then I submitted both the SIMs to the store & I left my village.
Then in September I came to know that the SIM has been activated the last month, then I told my friend in village to collect the SIM, he said the shopkeeper asking ₹120, then I sent via UPI, and he collected the 4G SIM, though network didn't came for the next few days (common issue in my village), then one evening it came, showing 2G bars, then again network gone.
Then in October I came back to my village, took the SIM, inserted, BAM signal shows emergency calls only..
Now I turn it off keeping in my phone, 'cause network issue discharge more battery.
(BSNL tower is less than 100m from my home, clearly visible, which was installed in 2011, now suffering in network issue.
