I am using a airtel sim no. 8991961207036909729. in china since 2008. but from last few days its not working here, suddenly showing a message on the mobile screen “sim card registration failed” it cannot be possible because i am using the life time validity plan. moreover i got a recharge of rs 200 by flexi recharge by sms from india and the airtel company deducted all my money by activating different service like airtel radio, airtel chat, miss call alert and what not. even though i didnot activate any service. i have a option of receiving incoming calls and messages only, i donot have a option of sending sms or outgoing calls here in china with international roaming so how could i activate the other services without sending sms and calling to airtel company. but every time i got a message “thank you for subscribing airtel radio and you will be charged for this service” and a lot more messages while they charge from my account. i dont know what to do because i am in china now so cannot go to airtel customers service. kindly activate my sim as soon as possible. the calling no. of sim is 9896959551. thank you.
