Changing the settings in 2ndNumber app in case it is not connecting

Some users have reported issues with the app connecting the first time they use it. Here are a couple of tips to get it to connect:

Android

1. Tap the horizontal bars in the top left corner and tap "Transport Settings"
   
   
   
   
   
2. Under "Transport" select the option "UDP" (or "TCP" if "UDP" is already selected)
   
   
   
   
3. Some phones really struggle with their battery life, so have agressive battery management apps installed on them. Do be sure to turn OFF battery management for the 2ndNumber app - otherwise when your battery runs low, 2ndNumber will be shut down. Normally you find battery managment under "Settings" -> "Apps" -> 2ndNumber -> "Battery Management"
4. Some people have VPN apps on their phones - if you do, make sure you allow 2ndNumber through the VPN or to bypass it. VPN on mobile can cause issues with our apps.

iPhone

1. Tap "Settings" then tap "Network"
2. Change "Transport" from "TCP" to "UDP" (or vice versa)
3. Make sure "Background App Refresh" is switched on under iPhone "Settings" > "2ndNumber"
   
   


4. If the iPhone is company-managed or has Screen Time restrictions or MDM profiles, they may block or hide notification permissions for certain apps.

   Check for:

   Screen Time > Content & Privacy Restrictions

   MDM profiles under Settings > General > VPN & Device Management
   
   If it has any of these settings, you will need to speak to your organisation to allow the 2ndNumber app to receive calls in the background.
