According to Grok

Given the severe restrictions on internet and communication in North Korea, a North Korean soldier captured by the Ukrainian army would face significant challenges in calling home:

1. **Communication Infrastructure:** North Korea's international communication lines are tightly controlled. Outgoing calls, especially to foreigners or from abroad, would be extremely difficult to arrange without official channels.

2. **Access to Communication Devices:** Even if the soldier had access to a phone, the ability to dial out internationally would likely require special permissions or technical capabilities that might not be available to him.

3. **Security and Monitoring:** All communications would be monitored by North Korean authorities. A call from someone in such a situation would raise security concerns, potentially leading to further isolation or punishment for family members back home.

4. **Technical Barriers:** The phone number system in North Korea is not widely accessible internationally; direct dialing from Ukraine to North Korea would be practically impossible without specific routing through diplomatic or special channels.

5. **Diplomatic Channels:** Perhaps the only feasible way for such communication might be through diplomatic channels, where Ukrainian authorities would need to coordinate with North Korean diplomatic staff or through international organizations like the Red Cross, which sometimes facilitate communication in conflict situations.

Therefore, it's highly unlikely that a North Korean soldier could simply "call home" without significant external assistance, and even then, the process would be fraught with bureaucratic and security issues.
