 Обратите внимание на то что номер телефона это обязательное поле для заполнения.
-Если у вас не выходит указать номер телефона, то проверте чтоб ваш телефон соответствовал регулярному выражению **^\+[7,8,9,3]\d{10,11}$**.
+Если у вас не выходит указать номер телефона, то проверте чтоб ваш телефон соответствовал регулярному выражению **^(\+[7,8,9,3]\d{10,11})?$**.
 Если регулярное выражение вам не подхожит, то вы можете изенить его в настройках, см. опции в настройках выше.
 После изменения настроек они не сразу вступят в силу, нужно перезагрузить код django, для этого перезапустите **uwsgi**:
 > \# systemctl restart uwsgi
