Guy's,

I have two BIS Storm 9000 devices which I’d like to connect to our BES. I have tried one, it connects and activates fine and all functions work.

The only difference I can find between the device is the APN which is used?

BES devices connect to BlackBerry.net and BIS device connect to blackberry.net case changes with different ip addresses.

Why is there a difference and is there a significance to this, and can I change it with a flash of the firmware?

I was thinking along the lines of costs as out data plan is for BES traffic.

Hope someone can clear this up.

Thanks.

No such thing as a BIS or BES device, they are all the same and only the plans are different. If you want to connect to a corporate BB server then you need BES, otherwise BIS is fine for Hotmail, Gmail or whatever.

Did you even try to connect the 2nd phone to the BES? from the above it sounds like you just tried one and it worked. Correct me if I'm wrong.

If you did then, are you sure you have the right email and password when you do the enterprise activation? Please check that out. also are you getting any kind of error message on the phone when you try to activate it? authentication error or something?

Also BES and BIS are going to affect each other. I use both on my phone

So the APN IP difference is ok, and it's dependant on the SIM service?

Ability to connect to BES is on SIM. If you have one device that is activating and one that is not, try swapping the SIMs and try the "faulty device" again - you'll probably find that it works.

Both SIMs need the corporate data plan for use with BES.

Yes both devices work fine now as I have added the other one to the BES.

Both devices were hardward only but we had Blackberry enabled sims to put in them.

As long as the usage is coverged by our data plan I'm happy.

If a device fails to activate on the BES, contact your carrier and ensure that your service plan is provisioned for BES access. Most carriers charge a little extra to allow devices to be connected to a BES

It depends on your plan. I used to have the 10MB plan that is no longer available. It could do BES and BIS. I got screwed by Vzw when upgrading to Storm and they switched me to the unlimited plan for $45. The $29 plan for "personal" email will not allow BES connectivity - you will get a service error if you try. I tried to go back to the 10MB plan for $25 but they won't let me.

BTW - If you are on a BIS plan, the device will activate with BES when USB connected, but as soon as you disconnect USB you lose BES connectivity.
