Re: [Openbts-discuss] Configure SIM card for OpenBTS

[Kurtis H. <khe...@cs...>]

I might be wrong about some of my comments here, but I wanted to try to help.

You can use a major telco SIM with OpenBTS, but it's a little tricky
at times. As far as I understand, the SIM card details what provider
it is to match with, and what other telco providers they peer with.
The handset uses this information to connect to the basestation. This
means that the SIM card will only associate with a certain set of
towers that provide an appropriate Mobile Country Code (MCC) and
Mobile Network Code (MNC). It's trivial to set OpenBTS to the codes
for the SIM provider, but also HIGHLY ILLEGAL in most areas. As a side
note, I think that the basic testing MCC/MNC associates with all SIMs,
but I'm unsure of that.

The overarching point here is that it's possible to use your existing
SIMs but often complicated for reasons that are hard to understand.
It's probably better to get a SIM from another country (I use a stack
of Ugandan SIMs here in California) or a testing SIM as was sent out
on the list a few months ago. Then the SIM will ONLY associate with
your tower.

The list can feel free to correct me if I'm wrong.
