I have purchased Aircel Super Pro 3G dongle SIM on 5th December in Dhanbad. I recharged it with 447 unlimited plan. After 3G data 2GB was exhausted it switched over to 2G, no problem. But from last 3 days it is getting disconnected every minute on its own. Everytime I remove from my Laptop and connect it gets connected but after a minute it automatically gets disconnected with a prompt "SIM card not detected or is Invalid". I contected customer care and they told to recharge main balance with any amount. I then recharged it with Rs.20 but the problem still persists.
Mine is a dongle SIM with number 8507789929.
