SIM Profiles Overview
To make it easy for customers to identify and select the right connectivity option, Simbase uses color-coded SIM profiles. Each profile is designed around a specific pricing model, geographic footprint, and underlying SIM technology. While all profiles deliver reliable IoT connectivity, they differ in coverage, commercial structure, and technical implementation.
Below is an overview of each SIM profile and its intended use case:
Black
Pay as you go
Worldwide
Multi-IMSI
Global IoT deployments requiring flexible usage-based pricing and strong network redundancy
Green
Prepaid
United States & Europe (select countries)
Multi-IMSI
Designed for use cases that require higher data volumes/SIM
Red
Pay as you go
Worldwide
Single-IMSI
Global IoT deployments requiring flexible usage-based pricing and strong network redundancy
Blue
Pay as you go
Worldwide (focused on EMEA)
eUICC
Global IoT deployments requiring the latest SIM technology with OTA profile updates
Yellow
Pay as you go
Worldwide (focused on United States and Australia)
eUICC
Global IoT deployments requiring the latest SIM technology with OTA profile updates.
Cyan
Pay as you go
United States and Australia
Single IMSI
Cost-efficient deployments limited to the US and Australia
APN configuration may differ slightly between profiles and should be validated during device setup. Please check the MCC/MNC Lookup tool before configuring your APN.
You can confirm which profile your SIMs use by checking the label on the box/package they arrived in, or - if they’re already registered to your account - by clicking the Diagnostics button in the Simbase dashboard.
Multi-IMSI vs eUICC: Key Differences
Multi-IMSI SIMs store multiple International Mobile Subscriber Identities on a single SIM. This allows a device to automatically switch between different operator profiles based on location or network availability, improving coverage and resilience without requiring remote SIM management.
eUICC (embedded Universal Integrated Circuit Card) technology enables remote provisioning and management of SIM profiles. Profiles can be downloaded, activated, or replaced over the air, making eUICC particularly powerful for large-scale deployments and long-lived devices where physical SIM replacement is impractical.
Why SIMbase Uses Both Technologies?
By leveraging both Multi-IMSI and eUICC technologies, SIMbase combines immediate network redundancy with long-term flexibility. Multi-IMSI ensures resilient, plug-and-play connectivity, while eUICC enables remote profile management and future-proof deployments.
