How to know if your Mtn number has been registered, but this time am going to update you on other networks.
To know if your sim card has been registered on Glo, All you have to do is to text "Reg" to 3456, and you will receive a message whether your SIM has been registered or not.
For other network like etisalat and zain, there is no special code but you can try this to know how:
For Etisalat, you can verify your SIM card registration status by calling 200 or sending an email to email@example.com
you can also verify by calling 111 on your phone or by sending an email to firstname.lastname@example.org.
Hope this information help.
