Buying a phone tied to one carrier can feel limiting, especially if you change plans often, travel between countries or simply want to choose the best deal each month. That is why more buyers in Mexico are choosing unlocked 5G flagship phones. An unlocked, or liberado, phone works with any carrier, so you can switch SIM cards or eSIM plans whenever you like while enjoying the latest cameras, chips and displays.
This guide explains what to check before buying an unlocked phone and compares five current flagship models available unlocked in Mexico.
What to Check Before Buying an Unlocked Phone
Unlocked flagships give you freedom, but a few details make the difference between a good buy and a great one:
- 5G support: all the models below are 5G, so they are ready for faster networks as coverage expands.
- SIM and eSIM: eSIM lets you add a plan digitally, which is handy for travellers and anyone running two numbers.
- Screen size: 6.9-inch models suit video and gaming; 6.1 to 6.3 inches is easier to use with one hand.
- Camera system: look at the main sensor resolution, telephoto zoom and video features if photography matters to you.
- Storage: 256 GB is a comfortable size for photos, apps and offline content; 128 GB suits lighter users.
Keeping these points in mind makes it easier to compare unlocked iPhone and Galaxy models and pick the one that fits how you use your phone.

Five Unlocked 5G Flagship Phones
These models cover premium, large-screen and compact options, and you can see all of them in this unlocked smartphone collection.
Apple iPhone 18 Pro Max 256 GB
The iPhone 18 Pro Max pairs a brighter 6.9-inch Super Retina XDR display with ProMotion up to 120 Hz and the A20 Pro chip. Its 48MP Fusion main camera with variable aperture leads a triple 48MP system, and Apple describes it as having the longest battery life in an iPhone. An aluminium unibody design and Ceramic Shield on the front and back are built to last.
Apple iPhone 18 Pro 256 GB
The iPhone 18 Pro brings the same A20 Pro chip and 48MP Fusion main camera with variable aperture to a more compact 6.3-inch ProMotion display. It also gets a big step up in battery life and the same durable aluminium unibody with Ceramic Shield, making it a strong choice for anyone who wants Pro features in a smaller phone.
Apple iPhone 17 Pro Max 256 GB
The iPhone 17 Pro Max offers a 6.9-inch display, a heat-forged aluminium unibody design and Ceramic Shield 2 on the front for better scratch resistance. Its A19 Pro chip with vapour-chamber cooling runs Apple Intelligence smoothly, and the 48MP Pro camera system is built for detailed photos and long-range zoom.
Samsung Galaxy S25 Ultra 256 GB
For Android users, the Galaxy S25 Ultra combines a 6.9-inch display, a 200MP quad camera system and 12 GB of RAM with Snapdragon 8 Elite for Galaxy, a processor tuned for smooth gaming with enhanced real-time ray tracing. Its slimmer aluminium frame gives a more comfortable grip for such a large screen.
Apple iPhone 16 128 GB
The iPhone 16 is the most compact pick here, with a 6.1-inch display, the A18 chip and support for Apple Intelligence. Camera Control gives quick access to zoom and depth of field, the 48MP Fusion camera captures sharp everyday shots, and the improved ultra wide camera with autofocus handles macro photos. It also supports eSIM.
Which Unlocked Flagship Suits You?
- Biggest screen: iPhone 18 Pro Max, iPhone 17 Pro Max or Galaxy S25 Ultra, all at 6.9 inches.
- Pro features in a smaller size: iPhone 18 Pro.
- Android and maximum camera resolution: Galaxy S25 Ultra with its 200MP main sensor.
- Everyday flagship at a more compact size: iPhone 16.
Getting the Most From an Unlocked Phone
Before you switch, check that your current carrier supports eSIM if you plan to use one, and back up your old phone so your photos and chats move across easily. If you travel, you can keep your home number on one line and add a local plan on arrival. Updating the software as soon as you set up the phone ensures you get the latest security fixes and features.
Freedom to Choose Your Carrier
An unlocked flagship gives you the latest technology without tying you to a single provider. The iPhone 18 Pro Max and 18 Pro lead on battery and display, the iPhone 17 Pro Max offers a durable Pro design, the Galaxy S25 Ultra brings a 200MP camera to Android, and the iPhone 16 keeps things compact. Choose the best unlocked 5G phone for your needs and switch carriers whenever it suits you.
