17Network Selection? How does the SIM card select the network?
The Simplex SIM cards vs. A local SIM: The Simplex global SIM card is a roaming SIM card. The Simplex SIM card allows your device to connected to multiple networks with-in the country, for example in USA and Canada the Simplex SIM can use all the major carriers. This advantage can in some cases lead to slightly longer connection establishment times as the device has more enabled options to choose from. This can be compared to a local SIM that only works in one network in one country. Note: If the device has a roaming configuration (allow roaming) - ensure its enabled.


The Simplex SIM: Simplex Wireless does not apply network selection using the SIM card. Signaling between device (modem) and network will determine and match the capabilities of the device and the available networks/bearers, allowing the device to make decisions on what network it connects to. Different devices and manufacturers have different procedures for establishing a data connection. A requirement and must is that they all follow the guiding principles from GSMA.

How does the Device / Modem select the network: The device scans for available networks and attempts to the first network it sees, if it is allowed to connect to it, it will attach to it. The signal strength has to be in a level where the device is able to communicate to the network or “good enough”.

Manual Selection: If automatic selection fails or if the user prefers, most mobile devices allow manual network selection. This way, the user can choose from a list of available networks, typically accessed through the device's network settings menu. This method requires the user to have some knowledge or preference regarding the available networks.

Network Technology Compatibility: Your device will look for networks that are compatible with its technology (GSM, CDMA, LTE, 5G, etc.) and supported bands. If multiple networks with strong signals are found, it can prefer the one offering a better data connection (e.g., choosing a 5G network over a 4G network if the device supports 5G). Default device configuration is typically set as (automatically), ensuring best compatibility. Advanced users can set the desired technology and some devices allow setting even the band(s).
