The failure could relate to the phone, network or your subscription. Perform the following steps:
Make sure your phone is connected to a network, which isn’t overloaded or unavailable.
Check your subscription’s status with your service provider.
Check your phone’s memory. If the memory is full, you will not be able to receive message. Delete some contents in your phone’s memory.
Check the service number with your phone service provider. If the number is wrong, you will not be able to send or receive message.
If the previously described options do not help, you can contact our hotline or repair center to get more professional technical assistance.
