I just turned on my phone that I use otherwise exclusively in SXM with the Chippie SIM card. It connected to the AT&T network here in the States. I dialed #191# and got a response showing the expiration date had been extended as mentioned above.

I share ruralcarrier's lack of confidence nonetheless. My guess is that dialing #191# is probably more reliable than depending on the web site, but even that might not be 100% reliable. Any reason for any of us to believe CHIPPIE/UTS is any more reliable than GEBE?
