I HAD USED AIRCEL FOR MORE THAN 3 YEARS AND I HAVE REALISED THAT AIRCEL IS THE WORST NETWORK EVER.AIRCEL HAS SOME ADVANTAGES BUT THE LIST OF DISADVANTAGES ARE MORE.FOR EXAMPLE NO NETWORK GIVES YOU UNLIMITED 2G INTERNET EXCEPT AIRCEL BUT AT THE SAME TIME AIRCEL NETWORK DOESNT WORK IN TRAIN AND SOMETIMES THERES IS CROSS CONNECTION PROBLEMS.SOMETIME THEY PROVIDE US UNNECESSARY OFFERS AND CUT OUR BALANCE WITHOUT NO REASON.SO CHOSE YOUR MOBILE NETWORK WISELY GUYS.
