Get a device online
To establish network connectivity, turn on your device. Then, you need to make two important configuration changes:
- Configure the APN so the device can connect to the emnify network.
- Enable roaming.
After that, the device registers to a network (no PIN code entry needed). Once it has registered, your device's Connection changes to Attached. SMS services are now available.
When your device has established a data session, the Connection changes to Online. This means it's ready to send or receive data traffic.
Verify a device's connectivity status in the emnify Portal under Connected Devices.
Configure the APN
Any device equipped with a SIM card requires an Access Point Name (APN) configuration to establish a data session. Some devices and networks auto-detect the APN, but you need to configure it in most cases.
APN: em (or alternatively use emnify)
If your devices have an emnify SIM card, the APN must be em or emnify.
No username or password is required.
Further, some Android or iOS-based devices and cellular modules must also be configured to allow roaming.
Common configuration steps often involve:
- AT commands
Cellular module settings are done in the device firmware (applies to cellular modules). - SMS commands
Settings are done via SMS (usually for GPS trackers and routers), so you don't need to connect with the device. - Device configurator
Devices must connect through a different interface (serial, USB, Wi-Fi, Bluetooth), and then a graphical configuration user interface guides you through the process.
