Sim900B dont receive SMS

[ThiVu]

My project with SIM90 can send/read SMS, make voice call..
But it havent yet received SMS:
- I insert sim card into slot.
- Initialize SIM 900B with CPIN / CREG / CSG -> everything OK
- Send SMS --> OK
- Then I use another mobile phone to send SMS to the sim card in slot
- Then use command CGML to list all SMS but respond is only old messages.
- I also insert that sim to my mobile phone to read SMS but there are only old messages
----> I have to send some commands to configure received message???

Thank you!
