According to the instructions sent by the Government, if you need to leave your home, you must inform the General Secretariat for Civil Protection by sending a text message to 13033.

The text messages sent and received are free of charge and sending the text message is not impacted by MIS message blocking, which you may have activated, so your messages are sent and received normally.

Why do I receive a charge notification if sending the text message is Free of charge?
Certain devices running Android OS, display a warning message indicating that sending the specific text message may incur charges, because you are sending the text message to a 5-digit number. This is an automated text in the Android OS, however sending a text message to 13033 does not incur any charge.

How to send a free text message to 13033  

1. Initially, enter the number 13033 in the “To” field, and then add the information required according to the instructions of the General Secretariat for Civil Protection. More specifically, enter the number that corresponds to the correct type of movement, and then enter your full name and address.
2. The number you enter before your personal information corresponds to a reason for going out: 
   1. visiting the pharmacy or the doctor
   2. visiting a store for supplies
   3. going to the bank
   4. providing help to individuals in need
   5. going to a ceremony, and 
   6. exercising outdoors or walking a pet.
3. Select Send and as soon as the warning message is displayed, choose Remember my Choice, and then Always Allow, so that from that point onwards the message can be sent without this warning being displayed.
4. If you have sent a message with the correct information, you will receive a confirmation message shortly thereafter, specifically ΜΕΤΑΚΙΝΗΣΗ (MOVEMENT) number, full name, and address.
   If you select Never allow by mistake or if you selected this option in the past when sending a text message to a different number, then you have activated text message blocking to 5-digit numbers from this device, so you will not be able to send a text message to 13033.
