Windows Phone 8 IE fails without SIM card
During some recent testing of several webpages, colleagues of mine discovered that they wouldn’t load on a Nokia Lumia 520. No visible errors, just a blank page. When testing the same page on our other phones (iPhone 5, Nokia Lumia 925 etc.), everything worked correctly. For some reason, there was a difference between the other phones and the 520 - What was most puzzling was that there must have been a difference between the other Nokia phones and this one.
While working in another area weeks ago, a problem had been solved on mobile devices that involved requiring a SIM card to be inserted into the phone before the webpage would finish loading. I don’t know what prompted us at that stage to think of the SIM card, but this issue came to my mind during the testing of this issue on the 520. As it turns out, adding the SIM card to the phone solved the problem. Once the SIM card was inserted, the webpage would load normally (by refreshing and from the Twitter application). No code changes were necessary, and no ugly hacks.
I’ve had it suggested to me that this is a bug, but I still have a gut feeling that this may be a security “feature” that restricts some functionality of IE mobile when there isn’t a SIM card in the device. If anyone has had this issue, or know why it occurs, I’d love to hear from you in the comments.
