Hello, everyone here:
  I also has the similar confusion. I use Iphone, Nokia and Huawei MS to test openBTS, I set the MCC and MNC the same to local provider, and then I find Iphone can automatically disconnect with the local provider and access to the openBTS, but the Nokia and Huawei can not.

1. Does the difference completely caused by Iphone?
2. Further more, how to configure the openBTS can make other mobile phone automatically access to openBTS?

The URL http://www.mentby.com/Group/openbts-discuss/noob-configure-questions.html discussed the same questions but I still confused!
Thank you..

The descriptive text reads "If *not* NULL, allow unprovisioned handsets
to attach in Um".

1. Leave it as NULL. Who is "they"? They are wrong.
2. You set Control.LUR.OpenRegistration to a regex to match against the
3. Do NOT set your MCC and MNC in the OpenBTS software to a local
provider. You may get phones that try to register to your network, but
your network should properly deny them.

If you don't know what you are doing, then I highly recommend *NOT*
changing Control.LUR.OpenRegistration or any of the cellid parameters
away from their defaults, unless you *COMPLETELY* understand any
possible consequences (and are prepared to face them).

Also, please review the manual here:
