Yes it is though you will need to figure out which network your going to use before traveling. Some networks overseas are compatible and some aren't. In the Philippines for example they have four main carriers the the phone will only work on two of them. Must established carriers I've dealt with have they info you will need to know on their websites as well as instructions about how to obtain a SIM for their network. I usually try to obtain one before traveling so that my phone will work right off they plane. Pretty much all LTE phones on Verizon are SIM unlocked out if the box.How well it will work well depend we network you choose.
