While Sideline calls go through your carrier's network to provide the best call quality, it is crucial to have a strong data or Wi-Fi signal at first in order for the Sideline call to connect to the Pinger Voice Network (PVN), and allow the call to reach your contact.
Once the call successfully connects, it switches over to your carrier's network and uses your minutes. Therefore, it's important to understand what exactly your service plan entails, otherwise, standard fees may apply.
If you attempt to place a call or send a message with your data or Wi-Fi turned off, you will receive an error message to check your network connection.
The only exception to this rule is if you have subscribed to unlock Wifi Calling.
Depending on your cellular plan, you may be charged by your service provider if you use VoIP calling with your data.
We recommend you contact your service provider with any questions about calling or messaging costs and what your service plan entails.
