SIMposium will look at how the SIM card has evolved, what private networks need to know when buying SIM cards and why 5G SIM cards are special.

Registration for this event is now closed.

About the event

Nothing makes SIM cards sound less glamourous than calling them Subscriber Identity Modules. But not only are they crucial parts of every mobile phone network, they are fabulously powerful. A computer within the computer that is your phone.

This Connected Devices SIG event, run in collaboration with the DCMS funded Best of British project, is aimed at anyone who works on building networks or devices. It will require a general knowledge of mobile technology but not specialist understanding of SIM cards.

SIMposium will look at how the SIM card has evolved, what private networks need to know when buying SIM cards and why 5G SIM cards are special. We’ll hear from developers producing applications to run on SIM cards and learn what it takes to make your own SIM cards.

And we will ask the question, “If the SIM dictates who owns the customer does the eSIM sound the death knell for the mobile operators?”.

Kindly hosted by Telet at their London office, this event is free to attend but places are strictly limited.

Introduction to topic from James Body, Telet


'Build your own SIM factory at home' Michael Moorfield, Mindszi

Build your own SIM factory at home

For years the rule has always been one SIM belongs to one mobile operator forever, it could never ever be changed. With eSIM the rules are different. Using eSIM, Remote SIM Provisioning and a few lines of code it's possible to configure a brand new SIM with a profile from any mobile operator. It’s even possible to put multiple operator profiles on a single SIM and switch between them if you need to. In his session Michael will talk about how the power to create a SIM that can connect to any mobile operator in the world, right from your kitchen table is within reach.


'Why do our own SIM card’ - James Body, Telet

'Why do our own SIM card’

In building an end to end network, from device configuration and spectrum licences through RAN and core to interconnect, the SIM card is an essential building block, but one which is often overlooked. Telet decided it needed its own multi-imsi, multi crypto SIM cards to be able to have the necessary level of service for its customers.


‘Developing SIM Apps’ - Robert Wakeling, Wadaro

‘Developing SIM Apps’

A modern smartphone is a fantastically powerful computer, while a SIM card is impressive for being a computer at all it’s very much the poor relation. So why would you choose to embed apps in SIM cards and how do you do it.


Refreshments and networking


'Tales from the front Line’- Bianca Brisc, Telet

'Tales from the front Line’

Bianca has developed the Telet SIM with two different manufacturers in both physical and eSIM formats. She explains the hurdles and things to be learnt when defining a SIM


Panel session with all speakers and additional panellist; Ben Wood, CCS Insight. Chaired by Nick Hunn of WiFore Consulting & CW SIG Champion

The speakers from the event are quizzed by Nick Hunn on the future of SIMs, eSIMs and the industry. Are the radical changes we are facing in the make-up of the industry enabled by the shift in the power over creating eSIMs or are eSIMs a reflection of those changes.

With additional panellist Ben Wood, CCS Insight


Closing remarks, Simon Rockman, Telet


End of session followed by opportunity for informal networking

  • The Superhero SIM by Nick Hunn

    Almost everyone in the world knows what a SIM is. It’s the little piece of plastic with gold bits on it that makes your mobile phone work.  Almost nobody in the world knows how a SIM works. That’s about to change, as over the next few years we’re going to see SIMs disappear. Or at least the bits of plastic...
