eSIM vs roaming in South America
How to keep your mobile data working wherever you wander
The sun’s setting behind the Andes, you’re fresh off a long bus ride, and—of course—your phone pings. A new WhatsApp message from your mum: “Did you arrive in Cusco? Send a photo!” Except there’s no Wi-Fi in sight, your UK SIM card’s gone rogue, and the last time you checked your roaming bill, you nearly choked on an empanada.
If that scenario sounds familiar, you’re not alone. Every December, thousands of travellers hit South America’s cities and surf towns, hoping to share Christmas market snaps or find that elusive midnight asado on New Year’s Eve. Staying online isn’t a luxury—it’s a lifeline to local info, directions, and (let’s be honest) showing off your tango attempt in Buenos Aires. But in 2025, is traditional roaming keeping up, or is it time to make the leap to eSIM?
Quick Facts
- Local eSIM plans start from £5/$7/€6 for a week of data in most major South American countries
- Switch networks instantly—no need to track down a local shop or fiddle with SIM tools
- Monitor your usage with Graba SIM’s Data Pulse, avoiding nasty surprises
- Some cities (hello, Medellín!) have patchy public Wi-Fi, making reliable mobile data a must
- 24/7 live chat support via Graba SIM is a real lifesaver if you’re stuck, especially over Christmas or New Year
Why staying connected in South America needs a smarter approach
Picture Christmas Eve in Valparaíso’s old quarter—colourful lights strung across cobbles, the air heavy with cinnamon and grilling fish. Now add a horde of tourists, everyone uploading stories, and suddenly mobile data slows to a crawl. Unlike Europe, where coverage is dense even in rural corners, South America’s mobile networks can be a patchwork—fantastic in Santiago or São Paulo, less so on a Patagonian road trip. Many towns rely on one or two main carriers, and during holidays like Navidad or Año Nuevo, network congestion spikes. I’ve seen entire plazas in Lima grind to a digital halt as midnight fireworks begin. On the flip side, in places like Cartagena’s walled city, network signals bounce off stone walls, causing odd dead zones. Public Wi-Fi exists in some airports and cafes, but it’s often slow, and—if you’re hopping between markets in Quito or hunting for your hostel late at night—counting on it is risky.
Why This Matters
Choosing the right way to get online can mean the difference between breezing through your journey or wrestling with expensive, unreliable connections.
What makes eSIMs stand out (especially with Graba SIM)
Let’s get practical. Traditional international roaming on UK, EU, or North American plans can rack up £5-£8/$6-$10 per day, with unpredictable data speeds outside the main cities. Physical local SIMs are cheaper but a hassle—queues at airport kiosks, passport scans, sometimes even a local address required. And who wants to swap SIMs in the middle of a holiday street parade? eSIMs—digital SIM cards built right into your phone—sidestep all that. I tested a Graba SIM eSIM last Christmas in Buenos Aires: downloaded via QR code in minutes, activated before my plane even landed. No fiddling with SIM trays or nervous moments hoping I hadn’t lost my home number. With features like Data Pulse real-time usage monitoring, I could check my remaining balance from a home screen widget (very handy while waiting for an Uber in the pouring rain). Instant activation is not just a buzzword—on my iPhone 14, I was online within 30 seconds. Any hiccup? Graba SIM’s 24/7 live chat sorted a data top-up on Boxing Day faster than my local hotel staff could explain how to get to the bus terminal. The peace of mind, especially during peak festive travel, is hard to overstate.
Festive tip: Data Pulse saved my Christmas dinner plans
Ran out of data 30 minutes before a reservation—but a quick glance at the Data Pulse widget let me top up in seconds. Avoided another lost evening in a new city.

Final Thoughts
There’s something magical about catching the first Christmas fireworks over the Plaza de Mayo, or navigating a midnight samba street party in Rio, all while sharing the experience live with friends and family back home. From the chaos of holiday crowds to those quiet moments watching the sunrise over Lake Titicaca, I’ve learnt (sometimes the hard way) that keeping your connection sorted early lets you focus on what matters—adventures, not admin.
Roaming isn’t what it was a decade ago, but for most of us, eSIMs now offer the right blend of flexibility, value, and peace of mind. Particularly on festive journeys, when every minute (and every photo) seems to matter just a little more. Safe travels—may your data last longer than your Christmas pudding!
