Dual-SIM phones can make international travel much easier because your home number and travel-data line can coexist. The important part is deciding which line handles each job.
Assign mobile data deliberately
Set the travel eSIM as the data line after arrival. Keep the home SIM available only if you need calls, texts or verification messages, and review its data-roaming setting before departure.
Label both lines clearly
Simple labels such as Home and Nomadic reduce the chance of changing the wrong setting when you are already travelling.
