The whole army does not stipulate that recruits are not allowed to call home during training, which is decided by each unit according to its own conditions. Generally, troops with humanized management are allowed to call their families to report their safety on the first day. In the days to come, you can still use the IC card phone in the camp to call home during rest time or free time. However, some troops cut off all unnecessary social relations (especially the promiscuous love relationship of local young women) and restrict them from making phone calls in order to let recruits concentrate on training. This is also a discipline and routine. After the end of the new training and the company's distribution, the new unit can generally call home, provided that it does not affect the work tasks and does not disclose secrets.
