APN stands for Access Point Name. It helps your phone establish a mobile data connection through your carrier. Most SIMs and eSIMs configure it automatically, but incorrect settings can leave you with signal and no internet. Check your data line and use only the APN values your provider supplies.

GSM stands for Global System for Mobile Communications, a 2G standard that helped make SIM cards and international roaming widespread. Today, travelers should check that their phone is unlocked and supports local LTE or 5G bands, carrier requirements, and VoLTE for calls. GSM alone is not enough.
