Can a factory unlocked iPhone 4s that was used on T-mobile be transferred to Verizon?

I have a factory unlocked white 64gb iPhone 4s that I bought through Apple and have been using it with T-Mobile service.

My question for you all is: Is it possible to transfer this phone over to Verizon? I have read some things online about Verizon using CDMA and T-Mobile using GSM, but I'm not really familiar with what that means. The dates of the posts are also a bit outdated so I thought I would ask today.

Not possible

No, Verizon doesn't have 3G sim cards, only LTE because they are CDMA. Plus, T-Mobile has a $30/month, 100 minute, unlimited data, unlimited text plan. Why don't you use that plan?
