have iPhone 4g w/ AT&T, would like to transfer to Verizon Galaxy S3


Jun 24, 2014
Hi, I have come across a Verizon Samsung Galaxy S3 that was given to me. The problem is I have an iphone 4g which i currently have a plan for AT&T. My iphone 4 is really slow and I would prefer to switch to the Galaxy S3. If someone can please help me with the following:

1. Can I use my AT&T sim card for the Verizon Galaxy S3? If so will I be able to keep the current number?

2. If I can use the sim card, would other process would be needed to get it working (I loosely known anything about unlocking or rooting a phone, great explination would be needed)

Ps currently running on SCH-I535 4.4.2
