Anyone use a micro sim adapter for the 9900?

If so, what adapter did you use and any issues? I want to be able to switch my sim card back and forth between my 9900 and the Iphone 4s.

I read somewhere that the 9900 could be problematic in this regard, although a quick look at the 9900's simm slot doesn't reveal anything unusual.

Thanks for any help.

Physically speaking, the microSIM adapter will work fine.
However, the data plans are not compatible between the iPhone and BlackBerry, so swapping SIM cards between the phones isn't going to be a seamless thing.

You'll likely need to contact your wireless provider to adjust your data plan each time you change handhelds.

Thanks Penguin. As to the compatibility of data plans, I did this a few years ago with tmobile and don't remember any issues.

OK, I hope you have the same experience this time around.

T-Mobile is the most lax with data plan requirements, and since they don't sell the iPhone they probably don't have a specific iPhone data plan. You might get away with swapping back and forth on T-Mobile. I'd call it a 50/50 chance.

I tried using a BB and an Android at the same time on T-Mobile.
They wanted to different data plans. I had both on there. They must have done a Random Search and they decided I meant to drop the BB. While I was using the BB.
