If your network connection is low or fluctuating, calling #100 will not resolve the issue.
To rectify or "boost" your network signal, you can:
- Restart the device
- Activate then deactivate airplane mode
- Confirm the device’s network capability by going into Network Settings. Some devices only facilitate 2G/3G connection. You can switch between connections, example, from 3G to GSM only. Ensure a restart is done once any adjustment is made.
