Hi, zoeshungube apologies for the inconvenience caused, please contact your network provider's customer care to inquire about your subscription.
You may also try inserting a different sim card into your phone. If a different sim card works, it may mean that your sim card is faulty, and you may need to perform a sim swap with your network provider.
If a different sim card does not work also, your device may need to booked in for assessment. Please go to the below link to locate the closest Authorized Service Center to you.
