World Phone
A World Phone or Global Phone is a term not used much anymore because most smartphones manufactured after 2014 have the capability of working on different carriers across the world in different countries. Different countries use different cell phone technologies (GSM or CDMA) and on different frequency bands. If you own a smartphone bought after 2014 from any major brand like Apple, Samsung, Google, there is a very good chance your phone will work across the world in most countries. GSM is what the majority of the world uses, but some countries use CDMA only like Japan. Cambodia uses GSM networks for voice. They also use LTE but that technology is for data only currently. Some phones have the capability of working on CDMA and GSM networks, while some phones will only work on GSM networks. I know this is super confusing, so I’ll just leave a link below on how you can check if your phone will work in Cambodia.
