Does the +GCI - Country of Installation command work properly on this model?

Type AT%T19,0,nn (nn stands for country code). Press Enter. OK is displayed.

The changes to the country parameters are saved automatically.

To verify that the correct country has been configured, type ATI9. The country code is then displayed in decimal format. The following is an example of country, command and result codes.
