Hello. I got an airtel 4G sim with redmi 2 from flipkart. I have tried several times to send an sms to activate the new 4g sim from my existing airtel number but the message is not even getting delivered but there is no problem in delivering messages to other numbers . I have called up the airtel customer but did not receive any effective reply. The new 4G sim is showing tower but no calls or smses are being possible from it which i assume is because the sim is not activated it
Regards
