Installation

Argentina eSIM setup walkthrough

iOS installation (iPhone)

Open Settings > Cellular > Add eSIM
Select "Use QR Code"
Scan the QR code from your Nomad confirmation email
Label the plan (e.g., "Argentina Travel")
Set as cellular data line (not your default for calls)
Do NOT enable data roaming yet
Confirm the plan appears under Settings > Cellular

iOS 18: the "Add eSIM" option appears under Settings > Cellular > Add Cellular Plan. iOS 17 and earlier: Settings > Cellular > Add eSIM.

Android installation (Stock Android)

Open Settings > Network & Internet > SIMs > Add eSIM
Select "Scan QR code"
Scan the QR code from your Nomad confirmation email
Name the profile (e.g., "Argentina Data")
Set as mobile data SIM
Do NOT enable data roaming yet
Verify the plan in SIM manager

Manual installation (if QR fails)

If the QR code does not scan, use manual entry:

Go to Settings > Cellular > Add eSIM
Select "Enter Details Manually"
Enter the SM-DP+ address from your provider email
Enter the activation code
Complete the setup as with the QR method

Use manual entry when: camera cannot read the QR code, the email was forwarded without the image, or you are installing on a second device.

Configuration

APN settings for Argentina

Automatic APN configuration

Most eSIM profiles auto-configure APN settings for Claro AR's network. After installation, verify the APN is set correctly:

iPhone: Settings > Cellular > Cellular Data Options > Cellular Data Network
Android: Settings > Network & Internet > SIMs > (travel eSIM) > Access Point Names

A correctly configured APN shows the carrier name and data type. If the APN field is blank, your phone will attempt to auto-fill on first connection.

Manual APN entry

If auto-configuration fails (rare, typically older Android devices), enter APN settings manually. Check your provider's confirmation email for the exact values. Common fields:

APN configuration fields
Field	Value
APN Name	From provider email
APN	Provider-specific value
Authentication	None (most providers)
APN Protocol	IPv4/IPv6

Provider-specific APN values override Claro AR's carrier defaults. Always use the values from your provider, not generic carrier APNs.

5G and LTE band selection

5G is available in Argentina (limited coverage). To force a network type:

iPhone: Settings > Cellular > Cellular Data Options > Voice & Data > 5G Auto / LTE
Android: Settings > Network > Preferred network type > 5G/LTE/3G Auto

Switch to LTE-only to conserve battery in rural areas without 5G towers. 5G in Buenos Aires

Verification

Speed test and signal check for Argentina

Signal and network verification

Check your status bar: the carrier name should show Claro ARor a roaming indicator. Signal bars confirm connection strength. Go to Settings > Cellular to verify data usage is counting on the travel eSIM line.

"Claro AR" or roaming icon: Connected and working
"Searching...": Still connecting, wait 2-3 minutes
"No Service": Data roaming is off or wrong SIM line selected

Speed test

Run fast.com or Speedtest.net to verify your connection speed. Expected speeds on Claro AR: approximately 25 Mbps download. Speeds vary by location: airports and city centers are fastest, rural areas slower.

Verifying data roaming is active

Go to Settings > Cellular > (travel eSIM) > Data Roaming: ON. Test by opening any website in your browser. If it loads, roaming is active. If not, toggle data roaming off and back on, then restart your phone.

Dual-SIM verification

Confirm your home SIM still receives calls and texts. Confirm the travel eSIM handles all data traffic. Test: send yourself a text message to your home number. Then load a webpage. Both should work simultaneously. If data routes through the home SIM instead, switch your cellular data line to the travel eSIM.

Airport Guide

Arriving at Ezeiza (EZE) with your eSIM

Before boarding

Add your Argentina eSIM profile 24 hours before your flight. Scan the QR code from your confirmation email while connected to stable WiFi at home. After the profile downloads, disable it immediately under Settings so the validity period does not begin. Attempting installation at Ezeiza (EZE) over public WiFi adds unnecessary risk — the download requires a clean HTTPS connection that captive portals interrupt.

During the flight

During the flight, double-check that your Argentina eSIM is configured as the cellular data line. Do not enable it yet. Confirm that data roaming on your home SIM is turned off to prevent accidental charges the moment airplane mode switches off after landing.

After landing

As the plane parks, switch off airplane mode. Enable the Argentina eSIM under Settings and turn on data roaming for that specific line. Claro AR connects in 60-120 seconds. Your first notification pops up before the aisle clears. SIM counters in the arrivals hall charge a tourist premium ($5-10 for 5-10GB / 28 days) with a queue. Your eSIM is already active.

Leaving the airport

Use your Argentina data to check exchange rates before withdrawing cash from an ATM in the arrivals hall. Compare taxi and transit prices on your phone. Having data from the moment you land turns every decision into an informed one. Argentina's emergency number is 107/100/101 — it works without data, but having your eSIM active means you can also share GPS coordinates with emergency services.

Device Setup

Device-specific instructions for Argentina

iPhone (iOS 17+)

Carrier Config

Carrier troubleshooting for Argentina

Claro AR

APN: "claro.com.br" — enter under Settings > Cellular > Cellular Data Network (iPhone) or Settings > Connections > Mobile Networks > Access Point Names (Samsung). Leave username, password, and proxy fields blank. Save and restart data.

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "Claro AR" from the list. The phone locks onto Claro AR's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 23-25 Mbps in urban areas, 8-13 Mbps in rural coverage

Common issue: If Claro AR connects but web pages time out, the phone may have defaulted to your home SIM for data. Go to Settings > Cellular > Cellular Data and confirm the Argentina eSIM is selected. The home SIM handles calls only.

Resolution: Contact your eSIM provider's support with the SM-DP+ activation address from your confirmation email. Some Claro AR profile issues require a new QR code. Airalo responds via in-app chat in under 5 minutes; Holafly offers WhatsApp support at +34 644 44 37 97.

Movistar AR

APN: "movistar.es" — enter under Settings > Cellular > Cellular Data Network (iPhone) or Settings > Connections > Mobile Networks > Access Point Names (Samsung). Leave username, password, and proxy fields blank. Save and restart data.

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "Movistar AR" from the list. The phone locks onto Movistar AR's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 15-21 Mbps in cities, 5-10 Mbps outside metro areas

Common issue: Movistar AR's network occasionally delays eSIM profile registration during peak hours at major airports. If your phone shows "Searching..." for more than 2 minutes, turn off Automatic network selection, wait 10 seconds, then select Movistar AR manually from the operator list.

Resolution: Restart your phone after adjusting network settings. Movistar AR typically completes registration within 60-90 seconds of a fresh boot. If the issue persists, remove and re-add the eSIM profile using the manual activation code from your provider's confirmation email.

Personal

APN: "datos.personal.com" — enter under Settings > Cellular > Cellular Data Network (iPhone) or Settings > Connections > Mobile Networks > Access Point Names (Samsung). Leave username, password, and proxy fields blank. Save and restart data.

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "Personal" from the list. The phone locks onto Personal's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 15-21 Mbps in cities, 5-10 Mbps outside metro areas

Common issue: Some eSIM plans routed through Personal require data roaming to be enabled on the travel SIM line specifically. Leaving it off is the most common reason travelers report zero signal after landing in Argentina. Check under Settings > Cellular > [Travel eSIM] > Data Roaming.

Resolution: Toggle airplane mode on for 15 seconds, then off. This forces a fresh network scan without a full restart. Personal should appear in your carrier field within 60 seconds. If it does not, use manual network selection to find and choose Personal directly.

Dual SIM

Set up dual SIM before landing in Argentina

Data line setup

Configure the Argentina eSIM as primary data: Settings > Cellular > Cellular Data. Claro AR provides 5G/LTE coverage across Argentina's main areas. Turn off "Allow Cellular Data Switching" so the phone never reverts to your home carrier for data. That single toggle prevents the most common cause of unexpected roaming bills during travel.

Calls and SMS

Keep your home SIM active for incoming calls and SMS. Your phone number stays reachable, and two-factor authentication codes from banks and services arrive normally via text. Outgoing calls use your home number unless you manually switch to the Argentina line. For voice calls over data — WhatsApp, FaceTime, Telegram — those route through the eSIM's data connection on Claro AR.

Emergency dialing

Dial 107/100/101 from your phone at any time — emergency calls bypass SIM restrictions and connect through any available network in Argentina. Having the eSIM active adds the ability to share live location, look up hospital addresses, and contact your embassy through data-based channels.

Battery impact

Expect 10-15% faster battery drain with two active SIM lines. Your phone maintains two radio connections simultaneously. If battery life matters during a long day, disable the home SIM and rely on the Argentina eSIM for everything including WhatsApp and iMessage. Re-enable the home SIM at night for any pending SMS codes. Carry a Type C/I adapter for charging in Argentina.

Hotspot

Using personal hotspot in Argentina on eSIM data

Sharing data via hotspot is straightforward on most Argentina eSIM plans. Enable Personal Hotspot in Settings and connect your laptop or tablet. Claro AR's 5G/LTE network provides 15-20 Mbps typical through hotspot to tethered devices. USB tethering offers the most stable connection and charges your phone simultaneously — a practical choice for hotel work sessions. WiFi tethering suits quick connections at cafes or airports.

Provider restrictions

Some budget eSIM plans block hotspot at the carrier level. If personal hotspot is grayed out in Settings, your plan does not include it. Contact your provider before departure to confirm tethering is supported. Airalo and Saily include hotspot on most plans. Holafly's unlimited plans restrict tethering on some Argentina data packages — check the plan details page before purchase.

Data impact

Data drains faster through hotspot. Desktop browsers load full-resolution images and scripts that mobile browsers skip. Expect 150-200 MB per hour for browsing, 1.5-3 GB per hour for video, and 300-500 MB per hour for video calls. Disable auto-play videos and pause cloud backups on any device connected to your Argentina eSIM hotspot.

Registration

Skip Argentina's SIM registration with eSIM

Argentina requires DNI or passport required for physical SIM cards. At Ezeiza (EZE), registration means handing your passport to a carrier agent, waiting for the system to process your data, and hoping the activation completes before your ground transport leaves. An eSIM eliminates the registration requirement entirely. Buy it online, install at home, and connect to Claro AR the moment you land.

Connect to Argentina's 5G network via eSIM

Claro AR offers limited 5G availability in select areas in Argentina. 5G in Buenos Aires. Enable 5G on your eSIM: iPhone — Settings > Cellular > Voice & Data > 5G Auto. Samsung — Settings > Connections > Mobile Networks > Network Mode > select 5G. Your phone needs 5G hardware (iPhone 12+, Galaxy S21+, Pixel 5+). Expected speeds on 5G: 25 Mbps in urban areas. "5G Auto" on iPhone conserves battery by falling back to LTE when 5G speed is not needed.

WiFi Backup

Activate your Argentina eSIM without reliable WiFi

Public WiFi in Argentina is good. For eSIM installation, use your home WiFi before departure. The QR code scan downloads a small profile (under 1 MB) from the carrier's server. This transfer needs a clean connection — captive portals and login walls at Ezeiza (EZE) or hotels can interrupt it.

Activating without WiFi

Fallback if WiFi is unavailable: manual SM-DP+ entry. Your confirmation email from the eSIM provider includes a server address and activation code. iPhone: Settings > Cellular > Add eSIM > Enter Details Manually. Samsung: Settings > Connections > SIM Manager > Add eSIM > Enter Activation Code. This method works over any internet connection. Save the email offline before departure so you have the codes even without connectivity.

Multi-Country

Adding Argentina to your multi-country eSIM setup

Multi-country travelers benefit from per-country eSIM profiles. A dedicated Argentina plan on Claro AR runs faster than a regional eSIM because it connects to the local network directly instead of roaming. Install all profiles at home, label them by country, and switch at each border. iPhone stores 8 profiles; newer Samsung devices store 10 or more. Argentina plans start at $4.49 for 1GB.

Switching eSIM profiles between countries

To switch from a previous country's eSIM to Argentina: iPhone — Settings > Cellular, tap the old country's eSIM, toggle "Turn On This Line" off. Tap the Argentina eSIM, toggle it on, and confirm it is set as Cellular Data. Samsung — Settings > Connections > SIM Manager, disable the old SIM, enable the Argentina SIM, set it as Mobile Data. Claro AR registers within 60-90 seconds.

Fixes

Fixing installation issues for Argentina

"eSIM Not Supported" error

Cause: Your phone is carrier-locked or the model does not support eSIM.

Fix: Contact your home carrier to unlock (24-72 hours). Verify your model supports eSIM at our compatibility list.

"Unable to Activate eSIM" error

Cause: eSIM profile slot is full, or the QR code was already redeemed.

Fix:Delete unused eSIM profiles in Settings > Cellular. iPhones hold 8 profiles (2 active). If the QR shows as used, contact your provider for a replacement code.

Connected but no data

Cause: Data roaming is off on the travel eSIM, or data is routing through the home SIM.

Fix:Settings > Cellular > select travel eSIM > Data Roaming ON. Also verify: Settings > Cellular > Cellular Data > select the travel eSIM as your data line. Restart your phone after making changes.

Slow speeds on Claro AR

Expected: 25 Mbps. If speeds are noticeably lower: toggle airplane mode on and off. Move to a different area. Try forcing LTE if 5G is congested.
