Oh Dell, the world is on your side: everyone wants a Dell Venue Pro and you have a unique chance here to really make a splash in the smartphone market. Too bad you can't seem to get this launch right. First there were delays, broken dates, mislabeled batteries, Wi-Fi issues and now we're hearing SIM card problems. They finally responded recently.

Issue is this: the few customers who had bought early "engineering" models are being called and told that the new replacements are available at the Microsoft stores. Upon exchanging and replacing the SIM, it turns out the Venue doesn't read them and errors out stating "Sim is invalid or not inserted". It's evidently not an isolated problem either:

Popped my SIM card in there and was faced with a SIM card error message. Having lots of phones I figured the card was not seated and opened it up and reseated it. Well to make a long story short.. I tried three different SIM cards in two other units and none of them would take the card. -Dan S

Going to XDA turns up more stories:

My brother's phone still works fine, but I rebooted my phone once and now my SIM won't be read. I've tried three different SIM cards and all won't read. -Arcarsenal

...same problem now that I have rebooted. The Sim can't be recognized anymore. -richlee111

And the same people witnessed multiple others in the store with the same problem. In the same thread, it is mentioned that Qisda is actually manufacturing the device. Looks like Dell has some calls to make. We still think the Venue Pro can make a solid phone, once these issues are sorted out. Lets hope that happens.

Thanks, Dan S., for the tip!
