What’s the code to lock your airtime?

Below is a quick short code you can use to lock your airtime on all networks from unauthorised use.

  • To lock your airtime; Dial this code, *33*0000# using the number you intend to lock the airtime
  • To unlock your airtime; Quickly dial, #330*0000# using the affected SIM and your airtime will be unlocked again for usage

Note that, since this code might be somewhat difficult for some people to memorise, I would recommend you to bookmark this page incase you forget any or either of the codes!

Can I use the code for any network?

Yes. The code is not network specific, and so can be used on any network in Nigeria (MTN, Airtel, Glo and 9mobile).

Who can use the code?

Anyone is eligible to use the code. This isn’t a network offer from telcos. With your SIM working and inserted into your phone, just dial the code and you are good to go.

Can I lock my SIM even without Airtime in it?

Well, I wouldn’t say no to that. But then, it’s best to lock your airtime when you have airtime in it. Locking when there is no airtime is somewhat meaningless.
