does not have a mechanical detection, or lock status pins.
If the SIM-card is removed during GSM operation the unit will shortly after be rejected from the
GSM network.
Please refer to Appendix B for detailed description of installing the internal SIM-card.

Commercial grade SD-CARDs can be used in applications where the limited write endurance is
acceptable - for example if the SD-CARD is often replaced. Commercial grade SD-CARDs should
not
be used in applications where a potential failure on the media is considered mission critical.
For applications that uses the SD-CARD media extensively and where a failure is critical, it is
recommended to use approved
Industrial Grade
SD-CARDs.
M2M Control has approved and recommends industrial grade SD-CARDs from
ATP
that is
available in capacities from 512 MB to 32 GB.
ATP Industrial Grade SD/SDHC Cards are optimized for demanding industrial applications with
consistent performance in all conditions. ATP uses reliable SLC flash technology with a flash
endurance more than 20 times higher than commercial grade products with MLC flash.
