Your EMnify SIM is designed to enable your device to connect to the best available network. With that being said, any endpoint's connectivity will affect the ability of the SIM to establish a successful connection with a network operator or will be disconnected if there is a network coverage issue (e.g. poor/weak signal, a dead spot which can be encountered commonly when a device is moving).
In order to give you a better understanding of how it really works, our SIM is not the one which is getting the signal instead it is the RF module of the device. The SIM is just small apparatus with a data base in it which store the profiles that will help the device to register to a network. Also, the connectivity depends on the behavior of the device.
Here is what you can try if you have unstable connectivity:
Blacklist the unstable operator (article)
- If the network operator has a weak coverage signal on the location of device.
- If It has a network outage.
- No roaming agreement between EMnify and MNO.
- No agreement between EMnify and Channel Partners (IMSI not supported).
Symptoms in EUI events that denotes unstable network
- Frequent disconnection of PDP context such create PDP and delete PDP (Only if the device is not moving or in one place)
- Established PDP but no data session.
- Took long to initiate create PDP
