– When you are abroad, your handset is automatically connected to a local operator (the name of the local operator appears on the screen of your handset). If you can not call, send an SMS or surf with this operator, go to the settings of your handset and manually select another operator with whom you try.
– Just try restarting your mobile.
– To call someone from abroad, add the sign + or 00 in front of the country prefix. Do not forget to remove the first 0 from the phone number. For example: you want to reach the Belgian number 0487030405 from abroad. You must dial the following number: +32487030405 or 0032487030405.
