What is it for?

To allow consumers to check that the mobile number they are calling is in the same network (as the prefix i.e. 012/013/016/018 no longer has any operator significance). To do so, please click here: Mobile Number Check.

The result will let the consumers know whether the number to be called is either:

"On-Net call" (within the same network) or
"Off-Network call" (the called number is in a different network)

and consequently may be of a different rate/charge.

Alternatively, now you can also check the On-Net/Off-Net call using your hand phone through SMS information service as follows:

Type check <mobile number> send to 22099 E.g. check 0192345678 send to 22099		Type check <mobile number> send to 22011 E.g. check 0122345678 send to 22011

Type check <mobile number> send to 20000 E.g. check 0162345678 send to 20000		Type check <mobile number> send to 28011 E.g. check 0182345678 send to 28011

All SMSes sent and received to check your mobile number through the numbers above are free of charge
