Guys,seems like no expert is going to help me to get me out of this confusion.

The Verizon one should work fine as that is unlocked. The sprint one however you will need to get unlocked. You can try one of those IMEI unlocking sites like officialunlocks.com but not sure if they can do an iPhone 5 on sprint.

Thanks Simon for your prompt response,but if the bill is not paid and It will become phone with bad ESN can it be still use on GSM network in overseas.

Not too sure of that.

Get it unlocked first before 'not paying the bill'. Once you are in your home country their network unlock will be permanent. Though you'll have a hard time getting a new sprint account
