Zero1 overseas usage for calls and sms is chargeable and expensive !!!VoLTE, or Voice over Long-Term Evolution, is a technology that enables high-quality voice calls and SMS over 4G LTE data networks, allowing users to simultaneously make calls and use high-speed internet, unlike older networks where calls would drop data. Key benefits include clearer HD audio, faster call setup, and better multitasking (e.g., browsing while calling) because the phone stays on the 4G network. It's built into modern smartphones and carriers' networks, with settings usually found under Mobile Networks in your phone's settings
From google less jargonsGlad you enjoyed you trip!
I set call forwarding on my zero1 line to my eight line since for eight , incoming and outgoing calls and SMSes in overseas are part of the plan and no extra charges will incur .
