FAQs
Frequently Asked Questions
Everything about SIM card integration – from connectivity to provider switching.
Which SIM providers are supported?
OB7 supports all common IoT SIM providers, including 1NCE, Vodafone IoT, Telekom IoT, and more. Thanks to eUICC technology, you can switch providers flexibly.
What happens during network issues?
Multi-network SIMs automatically switch between available networks. If connection is lost, the station buffers data locally and syncs when reconnected.
Can I switch SIM providers without hardware replacement?
Yes, with eUICC-enabled SIM cards, you switch providers remotely via the OB7 dashboard. No on-site visit, no card replacement required.
How much data does a charging station use?
A typical charging station uses 5-20 MB per month. OCPP communication is very data-efficient. IoT flat rates cover this need cost-effectively.
How do I monitor my stations' connectivity?
The OB7 dashboard shows the connection status of all stations in real-time. For connectivity issues, you receive automatic alerts via email or push.
