I already have a post paid Verizon data plan that I use with a USB stick and my laptop. I cut the SIM card today and made it to a micro SIM. Now, when I plug it into the iPad, it always gives the following error. Could not activate cellular data network The things I checked based on the search results. 1. PRL is up to date. 2. Tried reset network settings method. 3. Tried re-provisioning (waited for 10 minutes and then did a reboot). 4. Tried clear all settings. In order to verify that I did not make my SIM a dud while cutting, I plugged it into the USB modem and it works great on my laptop. The top left hand side shows "verizon 3G" with approximately 3 bars. Any ideas on how I can resolve the problem? Thanks!
