Simple solution: if the airtime deduction is via SMS charge. Edit your SMS center number; just remove a few zeros and then save. As long as the SMS center number isn't correct, your phone can't send any messages.

You will have to edit the SMS center number anytime you want to send an SMS, but you will always receive SMS even with the edited SMS center number.

Do this and thank me later.

Hi, mine is not via SMS. Though I've experienced this In the past and changed the center number, now the airtime will just suddenly drain without any notification. I called customer service and I was told I made an international call which drained my airtime. I'll just randomly see a text in my message outbox reading "sk2#6225000554389741#@X@hello"

Hi, my Gionee s10c has been making some background international calls, thereby draining all of my airtime. I was told this when I called my service provider and I don't know how to solve it
