May be its the local network there.. I generally use it somewhere
between Pune and Delhi. Had good reception.
Only time I had an issue was in PEK, when the phone could not lock on to the
service for a couple of hours within the city.. but thats about it.
I don’t know, because i had the alert setup if its undeliverable, and I never received any and Airtel kept taking my money.. I even called CS and they said it cant be credited..
WHat i didn't like is the fact every single person who calls does a miss call.. I had to refill every week.. Always Rs.350
