How to fix bugs df xx 2700 6fia

This error relates to a sim-card and says that service can not be used on this SIM-card.

Of the solutions I can offer the following.

  • Turn off the device and pull out the SIM card, clean the contacts on it hard eraser, perhaps they simply oxidized and push back;
  • Option Two – Change sim card in the operator’s office. Because this problem occurs more often on Beeline, it would be nice to change mobile operator;
  • In the setting of mobile tick "choose an operator automatically".

Something of the above you should help.
