I would flash your phone back to stock if you are going to be traveling internationally.
There are some settings especially for GSM data that are a pain to set on non stock roms.
A stock rom ensures that your phone has the correct APN set for Verizon global data.

Voice roaming is extremely expensive on Verizon, expect to pay $2-3 a minute.
Data roaming is expensive unless you buy their Global Email plan, it is $65 dollars a month.
So if you have a $30 data plan it will be $35 extra for the month.
If you are only going for a week they will prorate it so that you will pay much less.
