Country Dialing Codes (travel edition) is an independent guide for travellers who want to stay reachable abroad without nasty surprises on the bill. We focus on the practical side of using your phone in another country: roaming, local SIMs and eSIMs, mobile data, and calling home.
What we help with
Before you leave, we help you decide between roaming, a local SIM and an eSIM; on the ground, we explain how to keep data working, how to call landlines and mobiles, and how to avoid the classic billing traps. Every guide is built around a real travel situation.
How we work
We test the steps we describe, compare operator conditions, and update guides when roaming rules or coverage change. Where the best choice depends on your destination or carrier, we lay out the options instead of pretending there is one answer.
