Sim blocked

 Hi @Shakira, is the SIM registered in your name or your wife's name? I remain available. Good evening.

Hello Ho. Team,
I have a Sim card unfortunately we did not credited for around one year the reason was that my wife did not used a lot now we are going to load money every month if you unblock our number 3770923528 would be highly appreciated.
