4. Select SIM Card

Please choose the SIM card that uses UMTS network or supports Volte function. Generally, it is recommended to open Volte function for better performance.

5. Use Suggestions

To obtain better sound quality of encrypted calls, please try to follow the following suggestions:

a. While making an encrypted call, please turn off WLAN as much as possible;

b. While making an encrypted call, please do not turn off the device directly;

c. Encrypted call is not supported while charging;

d. For dual-card dual-standby phones, the SIM card used for making encrypted calls should be set as the preferred      SIM card for the mobile data network

e. In areas with relatively large electromagnetic interference, such as roadsides, stations, airports, etc., the mobile phone should be as close as possible to the PvR when making a encrypted call.

f. When you are walking or talking in a noisy environment, try to speak in a calm tone and at a lower speed.

6. Limitations

a. PvR can support most of the high-end models of mainstream brand mobile phones, but it does not rule out that some models of mobile phones do not match this product due to their audio characteristics or Bluetooth communication characteristics, resulting in poor sound voice quality;

b. PvR doesn’t support CDMA or CDMA2000 network;

c. Since PvR is connected to the mobile phone via Bluetooth, the Bluetooth signal is very susceptible to external electromagnetic interference (especially the 2.4G WiFi signal), which will cause worse sound quality. Therefore, it is recommended that the user turn off the mobile phone WLAN and shorten the distance between the phone and PvR as much as possible during the encrypted call.

d. As the network conditions and technical status of mobile operators in various countries vary greatly, we can’t guarantee that PvR can make cross-border encrypted calls between all countries, nor can we guarantee that PvR can make roaming encrypted calls in all countries. When the sound quality of  cross-border or roaming encrypted call is not good enough, you can try to use VoIP for encypted call. It is recommended to use “WhatsApp” as the communication tool.
