We offer two types of SIM cards: Standard and Industrial. While the standard SIM card suffices for most general IoT use cases, we also have Industrial SIM cards for more demanding applications. This article outlines the key differences between these two options.
TLDR; Unless you have need for longer (20+ year) lifecycle, higher security or plan to operate in extreme environments, the standard sim will be just fine.
Standard SIM cards are designed to provide reliable connectivity for most IoT applications, offering a suitable range of temperatures and data integrity.
Industrial SIM cards go a step further, engineered to meet the demands of more intense environments, ensuring higher temperature tolerance and prolonged data integrity.
Here's a brief comparison table outlining the key differences:
| Standard | Industrial | |
|---|---|---|
| Form Factors | 2FF/3FF/4FF & Embedded | |
| Processor | SC000 32bit | ARM Cortex-M3 32bit |
| User Memory | 480Kb | 512Kb |
| Lifespan | 25 years at 25°C | 30 years at 25°C, 10 years at 105°C |
| Voltages | 1.8v, 3v and 5v | 1.8v, 3v and 5v |
| Erase/Write cycles | 100,000 | 500,000 |
| Erase/Write cycles per 64Kb | 10 Million | 50 Million |
| Power saving standby | Yes | Yes |
| Standard | Industrial | |
|---|---|---|
| Page erase time | 4ms | 4ms |
| OTP user Bytes | 256 Bytes | 128 Bytes |
| Asyncrhonous ISO 7816-3 | Yes | Yes |
| CPU Clockspeed | up to 28Mhz | up to 15Mhz |
| Usage GSM & ETSI | Yes | Yes |
Features for Industrial sim cards:
| Industrial sim standards: |
|---|
| Environmental parameter monitoring |
| Protection against faults |
| ISO 3309 CRC calculation block |
| True random number generator |
| Unique serial ID on each die |
While Standard SIM cards can handle temperatures up to 85°C, Industrial SIM cards are built for more extreme conditions, capable of functioning at temperatures up to 105°C. This makes Industrial SIM cards an excellent choice for applications with higher thermal requirements.
Industrial SIM cards have an increased number of read/write cycles. This means they can perform more operations before wearing out, making them more suitable for applications that require frequent data exchanges.
Data integrity refers to the longevity of the stored data. Industrial SIM cards offer up to 25 years of data integrity, 5 years more than the Standard SIM cards. This longer-lasting data preservation is crucial for applications where long-term data retention is essential.
Both Standard and Industrial SIM cards are suitable for IoT applications, but they cater to different needs and environments. Assessing your specific requirements will guide you in selecting the right SIM card that ensures optimum performance and longevity for your IoT devices.
