Local Authority SIM

SIM Specification

Mobius have been supplying Industrial SIMs to Local Authorities for over a decade. Because we understand the costs involved in swapping a SIM out we specify extended temperature range, bigger memory with more read/write cycles than consumer SIMs.

That’s why some of our original SIMs are still out there on the street, in some cases surviving the original on street kit they were put in.

Physical Specification


  • Combined 2G, 3G and 4G SIMs with CSD, CLI and SMS support
  • Standard, Micro and Nano Sizes
  • Temperature range can be specified as -25°C to +85°C and -40°C to +105°C
  • Guaranteed read/write cycles at 500,000 @ 25°C up to 5000,000 @ +105°C
  • 10 years- Data Retention Time
  • Form Factor 2FF/3FF
  • Type 64 Kbytes of available operating memory
  • Temp range: -35C to +85C

But more than the Physical spec is the Profile for Local Authorities(PfLA). This PfLA means that the network

  • Knows that the SIM will be on 24/7/365.
  • That the data shouldn’t be choked or stopped
  • That the normal consumer filters shouldn’t be applied.

What this means in practise is that your connection stays in profile which means it stays on longer than a consumer SIM out of profile. That it will reattach more quickly when it is disconnected and that the data will be transferred more quickly in real world application than on a consumer profile.

All of this even applies when you are roaming on the UK networks.
