How the profiles differ
Coverage and latency
A single network gives lower latency for fixed UK installations. Roaming profiles can use more than one network, for devices that move or must stay connected.
Roaming and permanent roamingNetwork selection
No profile uses network-side steering. Light steering follows a preferred-network list on the SIM, whatever the signal strength. No steering lets the device choose any network by the standard 3GPP method.
How a device chooses a networkTechnology support
LTE-M and NB-IoT support is network-specific, and roaming access varies. Monthly data is the usage a profile suits best, not a hard limit or a guaranteed speed.
Choosing a radio technologyPublic vs private SMS
Public SMS gives the SIM a reachable mobile number. Private SMS goes through our API and never travels over public SMS networks.
