I know that EC25-J can receive ETWS like the following message:

+ETWS PRIMARY:<message_id>,<serial_number>,<warning_type>
+ETWS PRIMARY:<message_id>,<serial_number>,<warning_type>,<year>,<month>,<day>,<hour>,<minute>,<second>
+ETWS SECONDARY:<message_id>,<serial_number>,<alphabet>,<page_number>,<total_pages>,<cb_data_len>
