Installation

Adding your El Salvador eSIM to your phone

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., "El Salvador 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 (Samsung One UI)

Open Settings > Connections > SIM Manager > Add eSIM
Select "Download SIM" then "Scan QR code"
Scan the QR code from your Nomad confirmation email
Name the profile (e.g., "El Salvador 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 and band settings for El Salvador

Automatic APN configuration

Most eSIM profiles auto-configure APN settings for Claro SV'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 SV's carrier defaults. Always use the values from your provider, not generic carrier APNs.

Verification

Confirming your El Salvador eSIM setup

Signal and network verification

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

"Claro SV" 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: 4G LTE (LTE typically 20-80 Mbps, 5G 100-500 Mbps where available). 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 El Salvador's main airport with your eSIM

Before boarding

Set up your El Salvador eSIM before you leave the house. The QR code scan takes 90 seconds over a stable connection. Use your home WiFi, not mobile data or airport networks. After the profile installs, set the eSIM to off so Claro SV does not register it during a layover. The data counter starts on first network connection, not at installation time.

During the flight

Use the flight to prepare your phone settings. Open Settings, navigate to Cellular, and verify the El Salvador eSIM is assigned as your data line. Turn off data roaming on your home carrier line. When you land, the only toggle left is enabling the travel eSIM.

After landing

After touchdown, open Settings, enable the El Salvador eSIM, and turn on data roaming for the travel line. Claro SV registers the profile in 60-90 seconds. Check your status bar for the carrier name and signal bars. SIM counter availability at El Salvador's main airport varies by terminal and time of day. Your eSIM eliminates that variable entirely.

Leaving the airport

Your eSIM gives you data before you clear customs. By the time you reach ground transport, your map is loaded, your ride is booked, and your hotel has your arrival message. Zero idle time at El Salvador's main airport. El Salvador's emergency number is 911 — 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 El Salvador

iPhone (iOS 17+)

Open Settings > Cellular > Add eSIM > Use QR Code.
Point the camera at the QR code from your provider's email. The profile downloads in 5-15 seconds on stable WiFi.
Tap "Add Cellular Plan" when prompted. Label the plan "El Salvador Data" to distinguish it from your home line.
Go to Settings > Cellular > Cellular Data and select the El Salvador eSIM as your active data line.
Turn on Data Roaming for the El Salvador line only: Settings > Cellular > [El Salvador Data] > Data Roaming > On.
After landing at El Salvador's main airport, toggle the eSIM on. Claro SV registers your profile in 60-90 seconds. If data does not connect after 3 minutes, add the APN manually: go to Cellular Data Network and enter APN: "claro.com.br". Leave username and password blank.
Verify: open Safari and load any webpage. If the page renders, your El Salvador data is active at 4G LTE speeds.

Carrier confirmation: Your status bar should display "Claro SV" or "Tigo SV" with 4G signal within 60-90 seconds. On iPhone, check Settings > Cellular — the El Salvador line shows "Claro SV" under Network. The "4G" indicator confirms your connection type.

Note: If the carrier field shows "No Service" after 2 minutes, go to Settings > Cellular > Network Selection, turn off Automatic, wait 10 seconds, then turn it back on. If Claro SV does not appear in the list, restart your iPhone (hold Side + Volume Down for 3 seconds, slide to power off, wait 30 seconds, power on).

Samsung Galaxy (One UI 6+)

Open Settings > Connections > SIM Manager > Add eSIM.
Select "Scan QR Code" and frame the QR code from your provider's email. The download completes in 5-15 seconds.

Enable Data Roaming: Settings > Connections > Mobile Networks > Data Roaming > On (for the travel SIM only).
After landing at El Salvador's main airport, enable the eSIM. Claro SV's 4G network registers within 60-90 seconds. If data does not connect within 3 minutes, enter the APN manually: Settings > Connections > Mobile Networks > Access Point Names > Add. Name: Claro SV, APN: "claro.com.br". Save and select it as active.
Verify: open Chrome and load any page. Data flowing confirms your El Salvador eSIM is active.

Carrier confirmation: Your status bar should display "Claro SV" or "Tigo SV" with 4G signal within 60-90 seconds. On Samsung, check Settings > Connections > SIM Manager — the travel SIM shows "Claro SV" as the connected network. The connection type shows as "4G".

Note: If "No Service" persists after 2 minutes, go to Settings > Connections > Mobile Networks > Network Operators, switch from Automatic to Manual, wait for the scan to complete, then select Claro SV. If the carrier does not appear, restart the device: hold Power + Volume Down until the restart menu appears.

Google Pixel (Android 14+)

Open Settings > Network & Internet > SIMs > Add SIM > Download SIM.
Scan the QR code from your eSIM provider's email. The profile downloads in under 15 seconds.
Confirm the download and label the SIM "El Salvador Data" for identification.
Set as mobile data SIM: Settings > Network & Internet > SIMs > El Salvador Data > Use for mobile data.
Enable roaming: Settings > Network & Internet > SIMs > El Salvador Data > Roaming > On.
After landing at El Salvador's main airport, enable the profile. Claro SV connects within 60-90 seconds. If data fails to connect, add the APN: Settings > Network & Internet > SIMs > [El Salvador eSIM] > Access Point Names > New APN. Name: Claro SV, APN: "claro.com.br". Save and set as default.
Open Chrome and load any page to verify data connectivity on Claro SV's 4G network.

Carrier confirmation: Your status bar should display "Claro SV" or "Tigo SV" with 4G signal within 60-90 seconds. On Pixel, check Settings > Network & Internet > SIMs — the travel SIM displays "Claro SV" as the active network.

Note: If the signal does not register within 2 minutes, go to Settings > Network & Internet > SIMs > El Salvador Data > Advanced > Choose network, switch to Manual, let the scan run, and select Claro SV. If it fails, reset network settings under Settings > System > Reset options > Reset Mobile, WiFi & Bluetooth.

Carrier Config

Carrier troubleshooting for El Salvador

Claro SV

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 SV" from the list. The phone locks onto Claro SV's 4G band and data resumes within 30 seconds.

Expected speed: Fastest 4G speeds in El Salvador's urban areas

Common issue: Claro SV'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 Claro SV manually from the operator list.

Resolution: Restart your phone after adjusting network settings. Claro SV 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.

Tigo SV

APN: "web.tigo.com.co" — 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 "Tigo SV" from the list. The phone locks onto Tigo SV's 4G band and data resumes within 30 seconds.

Expected speed: Reliable 4G coverage across El Salvador's main cities

Common issue: Some eSIM plans routed through Tigo SV 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 El Salvador. 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. Tigo SV should appear in your carrier field within 60 seconds. If it does not, use manual network selection to find and choose Tigo SV directly.

Movistar SV

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 SV" from the list. The phone locks onto Movistar SV's 4G band and data resumes within 30 seconds.

Expected speed: Reliable 4G coverage across El Salvador's main cities

Common issue: Movistar SV may show a signal bar but no data if the APN was not auto-configured. This happens on roughly 10-15% of El Salvador eSIM activations. Enter APN "movistar.es" manually under Cellular Data Network settings.

Resolution: Reset network settings: Settings > General > Transfer or Reset > Reset Network Settings (iPhone) or Settings > General Management > Reset > Reset Network Settings (Samsung). This clears saved WiFi passwords but resolves most Movistar SV registration failures. Re-enable the El Salvador eSIM after the reset completes.

Dual SIM

Dual SIM setup for El Salvador: keep your number, use local data

Data line setup

Set the El Salvador eSIM as your cellular data line: Settings > Cellular > Cellular Data > select the travel eSIM. All web traffic, maps, and app data route through Claro SV's 4G network at $4.99 for 1GB. Your home carrier never touches data traffic, so no roaming charges accumulate.

Calls and SMS

Your home SIM handles calls and texts on your existing number. No one calling you sees a difference. SMS-based verification codes for banking apps and login services arrive on the home SIM as usual. Data-based messaging apps (WhatsApp, iMessage, Telegram) use the El Salvador eSIM's data connection through Claro SV.

Emergency dialing

El Salvador's emergency number is 911. This call connects through any network, regardless of which SIM is active or whether you have data. Your eSIM gives you the additional ability to use GPS mapping to find the nearest hospital and to share coordinates with emergency responders via text or messaging apps.

Battery impact

Two active SIMs cost roughly 10-15% more battery. The phone runs separate baseband connections for each line. On days with heavy use, turn off the home SIM under Settings and leave only the El Salvador eSIM active. Your home number goes to voicemail until you re-enable it. El Salvador outlets are Type A/B — bring an adapter and a portable charger.

Hotspot

Tethering and hotspot with your El Salvador eSIM

Most eSIM plans for El Salvador support personal hotspot out of the box. Enable it under Settings > Personal Hotspot (iPhone) or Settings > Connections > Mobile Hotspot (Samsung). Your laptop, tablet, or travel companion's phone connects through your El Salvador eSIM on Claro SV's 4G network. Hotspot throughput typically reaches 4G speeds through hotspot, slightly below direct device connection. Video calls over hotspot use 300-500 MB per hour. A 1GB plan supports 6-10 hours of video calling before running low.

Provider restrictions

Not every plan includes hotspot. Holafly's unlimited eSIM plans for El Salvador restrict tethering to prevent network abuse. Airalo and Nomad include hotspot on their fixed-data plans. If the Personal Hotspot toggle is missing from Settings, the plan blocks it at the carrier level — no workaround exists without switching to a hotspot-enabled plan.

Data impact

Hotspot data consumption is higher than direct phone use: laptops pull desktop-resolution assets. Budget 150-200 MB/hour for browsing, 300-500 MB/hour for video calls, 1.5-3 GB/hour for streaming. Turn off cloud sync, OS updates, and auto-downloads on connected devices to protect your El Salvador data allowance.

WiFi Backup

WiFi and eSIM activation in El Salvador

El Salvador has moderate WiFi in urban areas; spotty in rural regions. The best approach: install your eSIM at home over your own WiFi before departure. The QR code scan transfers about 500 KB of profile data — it needs a clean connection, not speed. Airport WiFi at El Salvador's main airport uses captive portals that can interrupt the eSIM download. Install at home, travel with confidence.

Activating without WiFi

If you cannot scan the QR code, use manual entry. Your eSIM provider's confirmation email contains an SM-DP+ activation address and activation code. On iPhone: Settings > Cellular > Add eSIM > Enter Details Manually. On Samsung: Settings > Connections > SIM Manager > Add eSIM > Enter Activation Code. Enter the SM-DP+ address and code exactly as shown. This method uses your existing data connection (home carrier or WiFi) and does not require a camera.

Multi-Country

El Salvador eSIM on a multi-country trip

If El Salvador is one stop on a multi-country itinerary, install all country eSIMs before departure. Most phones store 8 or more eSIM profiles. Label each one clearly: "El Salvador Data," "France Data," etc. At each border, disable the previous country's eSIM and enable the next one. The switch takes 30 seconds under Settings > Cellular. A single-country El Salvador plan on Claro SV's 4G network delivers better local coverage than a multi-country regional eSIM — starting at $4.99 for 1GB.

Switching eSIM profiles between countries

At the El Salvador border, open Settings > Cellular (iPhone) or SIM Manager (Samsung). Disable your previous eSIM. Enable the El Salvador profile and set it as the active data line. Turn on data roaming for the El Salvador line. Claro SV's 4G network connects within 60-90 seconds. Do not delete the previous eSIM — you may need it on the return leg.

Fixes

When your El Salvador eSIM does not work

"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.

Provider-specific installation issues

Airalo: QR code in email and in-app. Re-download available in the app under "My eSIMs"
Nomad: QR delivered by email only. Check spam folder. No app required for installation
Holafly: QR code in app and email. Unlimited plans activate on first connection
