Prepaid data plans for travel in Argentina
esimbloom lists 37 prepaid eSIM plans for Argentina from $1.10 (the smallest is 100MB for 7 days). Every plan is data-only — mobile internet for maps, messaging and bookings, but no local phone number or SMS — and prepaid: pay once, no contract, no roaming charges.
These are data-only plans. You can use messaging apps, maps, email, and browse as usual, but you won't receive a local phone number or SMS. For voice calls, use WhatsApp, Telegram, or similar apps over your data connection.
How to set up your Argentina eSIM before you travel
Check that your phone supports eSIM technology before you buy. Most iPhones from XS onward and recent Samsung, Google Pixel, and other flagship Android models are compatible. Once you complete your purchase, you'll receive a QR code by email within minutes.
Scan the QR code from your phone's eSIM or mobile data settings while you're still connected to WiFi. The eSIM profile installs in seconds. Keep your home SIM active until you land, then switch your mobile data to the Argentina eSIM. Your plan activates automatically when it first connects to a network in Argentina.
Staying connected across Buenos Aires, Patagonia, and beyond
Mobile coverage in Buenos Aires, Córdoba, Rosario, and Mendoza is strong, and you'll find reliable connectivity in most provincial capitals and along major highways. Patagonia's mountain roads and remote estancias will have gaps, but towns along the Ruta 40 and popular trekking bases like El Chaltén and El Calafate are well covered.
If you're spending time in cafés, working remotely, or navigating with offline maps, expect to use 300MB to 500MB per day. Streaming video, uploading photos to cloud storage, or making regular video calls will push that toward 1GB daily. For long-distance bus journeys between cities, download content beforehand since coverage becomes patchy between urban centres.
Frequently asked questions
How much does an eSIM for Argentina cost?
esimbloom Argentina eSIM plans start at $1.10, with 37 plans to choose from. You pay once for the plan you pick — no roaming fees and no contract.
Do I need an eSIM for Argentina?
Only if you want mobile data without roaming charges. An esimbloom Argentina eSIM is installed from a QR code before you fly, activates on your first connection in Argentina, and is data-only — your home SIM stays in the second slot for calls and SMS, with its data roaming switched off.
Will my eSIM work in both Buenos Aires and Patagonia?
Yes. Your plan covers the entire country. Expect strong signals in cities and towns, with reduced or no coverage in remote mountain areas and stretches of Patagonian wilderness between settlements.
Can I use my Argentina eSIM for WhatsApp calls?
Yes. WhatsApp, Telegram, FaceTime, and other internet-based calling and messaging apps work normally over your data connection. Your plan does not include a local phone number or traditional voice service.
When does my plan validity period start?
Your plan activates automatically when it first connects to a mobile network in Argentina. The validity countdown begins from that moment, so install the eSIM before departure but keep it inactive until you arrive.
Do I need to remove my existing SIM card?
No. Your eSIM works alongside your physical SIM. Once you land, go into your phone settings and select the Argentina eSIM as your active mobile data line. You can still receive calls on your home number.
What happens if I run out of data before my plan expires?
Your connection stops when you exhaust your data allowance, even if days remain. You can purchase a second eSIM plan and install it the same way. Many travellers buy a smaller plan first to test their usage.
