Question about AT&T BlackBerry Curve 8310 Cell Phone - Red

2 Answers

All of a sudden my cell phone says that the radio signal is turned off. It is not true. I also get a message to insert a SIM Card. But I have a SIM card inserted. I have gone to the Manage Connections icon and verified that the box is checked in the "ON" mode. I have also removed the SIM card, blown on it to remove any dust and inserted it again. I really need help and advice since I am traveling abroad now and do not have access to an AT&T store.

I have nokia n70 but i cannot received and sent text messages nor cannot make a call keep saying network busy. please help me this.


Hello,

1. Turn the mobile phone off for a second and turn on, check if you have network signal. If still not working, try #2
2. Turn off the phone and remove the battery and sim from the phone for a couple of second. Return everything and turn on the phone. If still no network or no signal from you network provider, try #3
3. Turn off the phone and remove the battery and sim from the phone, insert the sim card to your other phone and check if you can make and receive calls and text messages.
4. Insert a your other sim card from your phone and check if you can do the same.

**With this, you can identify what needs to be repaired or replaced. (Sim card or Mobile Phone). If you cannot make and receive calls and text messages using no. 3 method, it is the sim card that has the problem and needs to be replaced. But if with #4, the phone has the problem and not the sim card. You need to contact your Service/Network Provider from technical help.

Thank you.

Password to delete all contacts from phone


You might need your phone's security code to do that! But I guess you forgot the code? Nothing to worry though, you can try these steps below:

  1. Turn off the handset and remove the SIM card.
  2. Turn on the handset WITHOUT the SIM card.
  3. At the Insert SIM card screen, enter *2767*2878# (that is, star 2767 star 2878 pound).

    If fails please try code *2767*3855# (that is, star 2767 star 3855 pound).
    • NOTE: The handset now resets to factory settings. This erases all downloaded content as well as pictures, text messages, and phone book entries that are saved to the handset.
  4. The handset automatically turns itself off and then back on, and then it returns to the Insert SIM card screen.
  5. Turn off the handset and insert the SIM card.
  6. Turn on the handset.
    • NOTE: It may take about one minute for the handset to find a signal after this procedure. After it finds a signal, the handset should then function as expected with the security code set back to default (00000000 8 zeros).
  7. Or if the steps above didn't work, try visiting this link

Hi,

The message you are getting from your phone indicates that no sim is present in your phone,perhaps you have inserted the sim in a wrong manner, hence the phone does not recognize the presence of the sim card.

Here is the solution;

1.Remove the back cover of the phone and remove the battery respectively,

2.Afterwards,re-insert the sim card in a manner indicated by an arrow located beside the sim port,or as described by the user manual.

3.Ensure you turn on the radio connection,which is located in the manage connection settings in the main menu.

Problem solved

No network coverage


Phone is not receiving any radio signal / received signal is too weak:
Confirm that network coverage is available where you are by contacting your service provider.

SIM card is not working properly:

Insert your SIM card into another phone
Note: Contact your service provider if you get the same message again.
Phone is not working properly:
Insert your SIM card into another phone. If the second phone works with the inserted SIM card, then
the problem is probably with the first instrument.

Note: In this case, contact your nearest Sony Ericsson service center regarding your phone problem.
