[Q] "Refreshing Sim Data" annoying pop ups

---

I've got an unlocked Singapore i9000 with the European JG1 firmware installed and using it on AT&T in the US.

The phone frequently pops up an annoying message about "refreshing sim data". It pops up, then fades away on its own.

Other than the obvious, what does "refreshing sim data" mean, and why does it do it so often? This is the only phone I've owned that does that.

Any idea what's going on behind the scenes (either on the phone, or at AT&T) when the phone pops up that "refreshing sim data" message? What's refreshing on the sim or the phone, and why does it do it so often?

On an interesting related note. The sim I am using is from my iPhone account on AT&T and is grandfathered in with the true unlimited data plan. What's interesting is that usually when I put the sim into another phone, like say my old Razr, the AT&T website almost instantly reflects that I'm not on an iPhone with that sim at the moment; with the i9000, the sim's been in it non-stop for almost a month now, and AT&T still reports me as an iPhone.

get this too, what is this?

I'm still getting this...

No one has any ideas? I've noticed that AT&T Web site now reports the phone as "unknown" but they haven't monkeyed with my grandfathered unlimited iPhone data plan (yet).

I get this on my captivate too. It happens on both Perception and Assonance roms. The only other thing I can think is that I have an old Cingular 3G sim card so maybe that is acting funky with it.
Anyone figure anything out with this?

I'm starting to get this too ever since I installed the Pheonix Rom on my Captivate. Never had this problem before. It even sometimes cuts off service when that pop up shows up.

I just started to see this on the new Cognition 3.0.4 rom for the captivate also. Any ideas?

I'm seeing it on my Captivate with Perception 10.2... I also have the old unlimited AT&T iPhone data plan. When I log into AT&T, it shows I am using the Captivate.

One more here. Paragon RC5 didn't do it but RC6 does. Phone is a Captivate with an iPhone sim card and data plan.

I started seeing this to when i started using JS8(my own) and see it using Darkyy's JS8. I only see this when I have my usb unplugged.

Possible rom has wrong CSC for the network you are using .
I have a manually entered network as its not on any CSC sim pops up and i just choose O2 UK as its the carrier for the network i use .
Result no more pop up .
Or change CSC to cover your current network .
