# JRS_ warns: due to the fact that today the occupiers have access to cellular equipment in the temporarily occupied territory of Ukraine, they may interfere in the work of mobile communications.
This can be done through “parallel” forwarding, which can be a call to two numbers at the same time – the direct subscriber and someone else’s number.
To protect yourself and your loved ones from such actions, we encourage you to use service codes to check for call forwarding on your number.
The following service codes are universal and suitable for all phones:
* # 21 # call – check the information about the included forwarding.
* # 43 # call – status of the call waiting service.
* # 62 # call – check forwarding to another number.
* # 33 # call – displays the blocking status of outgoing services: calls, SMS and data.
## 002 # call – delete all call diverts.
We recommend using encrypted messengers for confidential conversations.
