I want to drop my current plan (450 minutes/Unlimited data for $60/mo + taxes, so around $70 total) and switch to PAYG $0.25/minute and use Skype whenever I can, as I'm almost always near a hotspot, but want the PAYG as a backup and for in-bound calls. So once my contract is up or I buy it out, how can you convert to the PAYG plan? I know there was a way to start ou in PAYG if you entered a bogus SS# upon first getting the phone, but what is the process once you have already had normal service? Also, can you block data once you go PAYG? I don't want to accidentally click on email or Safari when I'm not on Wifi and pay $0.01 per kb.
