Why can't I get the information of Samsung 3900?

According to your description, please verify the model of your mobile phone. I suggest you try from the following aspects:

1. I suggest you go to Settings-Applications-All-SMS-Clear Data.

2. Restart the phone to see if there is a signal problem.

3. Try to replace another sim card, or wipe the contact point between the mobile phone card and the mobile phone (whether the SIM card is in poor contact).

4. Whether the SMS blacklist function is set in the mobile phone, try to cancel the SMS blacklist.

5. It is recommended that you try to upgrade the firmware. (Settings-About Equipment-System Update)

If you still can't send and receive SMS through the above methods, please bring the purchase invoice, maintenance card and machine to Samsung Service Center, and the engineer will check and handle the machine. For the specific service center of Samsung, please visit.
