Roaming zones are geographical regions defined by mobile carriers to categorize how they charge customers when they use their phones outside of their home network.
Each zone has its own pricing structure for roaming, which directly impacts how much you’ll pay for using your phone abroad for calls, texts and data.
Call and text costs vary widely based on the zone; costs for calling back home from a Zone 3 country could skyrocket to several dollars per minute.
Roaming charges are calculated per megabyte (MB), and the rates can be shockingly high in certain zones.
Some carriers offer roaming packages that let you pre-purchase a set amount of data, calls, and texts for a specific zone.
One of the simplest ways to save on roaming costs is to rely on Wi-Fi. Most hotels, cafes, and public spaces offer free Wi-Fi, allowing you to make calls, send texts, and use data without incurring extra charges.
eSIMs are becoming increasingly popular for international travelers, which allow you to purchase a temporary plan for the country you’re visiting.
Free roaming zones override the standard charges in certain regions like EU and North America.
A little knowledge and planning can go a long way in keeping roaming bills manageable.
The main reason roaming charges is expensive is because your home carrier has to negotiate rates with the carrier in the country you’re visiting.
