The biggest standard iPhone with the best Apple battery life. eSIM support means you can easily switch to a local data plan, and the camera system is excellent for travel photography.
The Samsung Galaxy S26+ is our top travel battery pick — it combines long battery life, a great camera and eSIM support in one premium package.
What is eSIM and why does it matter for travel?
eSIM lets you download a local data plan digitally without swapping physical SIM cards. You can buy a cheap local eSIM (via apps like Airalo) before you travel and activate it on arrival, saving significantly on roaming charges.
Should I get a power bank as well?
For multi-day trips, yes. A 10,000mAh power bank gives you roughly 2 full charges and fits in a day bag. Worth it for long travel days.
Is IP water resistance important for a travel phone?
Yes if you're visiting beaches, swimming pools or rainy destinations. IP67 (the Samsung A35) means the phone can survive being submerged in up to 1 metre of water for 30 minutes.
