This document discusses the challenges of interoperability between mobile devices and SIM cards. It provides statistics on the most popular mobile devices by country. It notes that standards in the industry often leave room for interpretation and competing standards. The document advocates for a "device capability server" that could detect device changes, configure devices and SIMs remotely, and help overcome interoperability issues between devices and SIMs from different vendors. It also introduces Sicap, a company that provides device and SIM management servers to mobile operators.

“Standards” challenges
 Often more recommendations than standards
 Drafted as a compromise between actors with
different (opposing) interests
 Leave a lot of room for interpretation
 Standards competing against each other
 Of all Telco standards, those involving SIM &
devices have the most complex lifecycle
Standard compliant systems often become
disguised proprietary systems

SIM vendors
The need for 4 way
interoperability across the
value chain
Device
OEM
OTA
Server
vendors
Ensure seamless “out of the box”
experience for-end users
Focus on device/SIM
communication / Near field tests
Identify problems before device &
SIM is in user hands
Key selling proposition for all
vendors (win/win)
Focus on cohabitation and
reuse of other embedded
software
Test “borderline cases” linked to
Hardware / Software
Need support from Hardware
vendors (developer programs)
Focus on client/server IOT for
management of the device/SIM
Identify build DB of device & SIM
specificities
Critical part as the OTA server
allows bypassing limitations
Plug tests should become
permanent
Focus on management of the
software agent after device is in
user hands
Step out of proprietary end to
end solutions
Allow cross-selling opportunities
for both vendors

"I have always wished that my computer
would be as easy to use as my telephone.
My wish has come true.
I no longer know how to use my telephone."
Bjarne Stroustrup
Computer scientist,
most notable for developing
the C++ programming language
And finally… why this is
important
