Installation

Saint Martin 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., "Saint Martin 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 (Google Pixel)

Open Settings > Network & Internet > Add eSIM
Select "Download a SIM instead" then scan
Scan the QR code from your Nomad confirmation email
Name the profile (e.g., "Saint Martin 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 Saint Martin

Automatic APN configuration

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

Verification

Testing data on Orange's network

Signal and network verification

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

"Orange" 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: 5G (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 Saint Martin's main airport with your eSIM

Before boarding

The night before your flight, open Settings, add a new eSIM, and scan the QR code from your order email. Your home WiFi provides the clean connection the download needs. After it installs, switch the Saint Martin profile to off. Leave it dormant until wheels touch the runway. Orange picks up the signal within 60-90 seconds of your phone leaving airplane mode.

During the flight

Keep airplane mode on during the flight. Confirm your Saint Martin eSIM is set as the designated data line under Settings before you descend. Your home SIM stays active for calls and SMS verification codes.

After landing

Once the seatbelt sign is off, disable airplane mode and enable the Saint Martin eSIM. Orange registers the profile in 60-90 seconds. You have maps, messaging, and ride-share access before the cabin door opens. SIM counter availability at Saint Martin's main airport varies by terminal and time of day. Your eSIM eliminates that variable entirely.

Leaving the airport

Your eSIM is working. Open your ride-share app and request a pickup while you wait at baggage claim. By the time your bag arrives, the car is already en route. No WiFi hunting, no SIM counter, no wasted minutes. Saint Martin's emergency number is 15/17/18/112 — 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 Saint Martin

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 "Saint Martin Data" to distinguish it from your home line.
Go to Settings > Cellular > Cellular Data and select the Saint Martin eSIM as your active data line.
Turn on Data Roaming for the Saint Martin line only: Settings > Cellular > [Saint Martin Data] > Data Roaming > On.
After landing at Saint Martin's main airport, toggle the eSIM on. Orange 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: "orange". Leave username and password blank.
Verify: open Safari and load any webpage. If the page renders, your Saint Martin data is active at 5G speeds.

Carrier confirmation: Your status bar should display "Orange" or "Dauphin Telecom" with 5G/LTE signal within 60-90 seconds. On iPhone, check Settings > Cellular — the Saint Martin line shows "Orange" under Network. If you see "5G" in the status bar, your phone has connected to Orange's 5G band.

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 Orange 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 Saint Martin's main airport, enable the eSIM. Orange's 5G/LTE 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: Orange, APN: "orange". Save and select it as active.
Verify: open Chrome and load any page. Data flowing confirms your Saint Martin eSIM is active.

Carrier confirmation: Your status bar should display "Orange" or "Dauphin Telecom" with 5G/LTE signal within 60-90 seconds. On Samsung, check Settings > Connections > SIM Manager — the travel SIM shows "Orange" as the connected network. A "5G" icon in the status bar confirms Orange's 5G connection.

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 Orange. 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 "Saint Martin Data" for identification.
Set as mobile data SIM: Settings > Network & Internet > SIMs > Saint Martin Data > Use for mobile data.
Enable roaming: Settings > Network & Internet > SIMs > Saint Martin Data > Roaming > On.
After landing at Saint Martin's main airport, enable the profile. Orange connects within 60-90 seconds. If data fails to connect, add the APN: Settings > Network & Internet > SIMs > [Saint Martin eSIM] > Access Point Names > New APN. Name: Orange, APN: "orange". Save and set as default.
Open Chrome and load any page to verify data connectivity on Orange's 5G/LTE network.

Carrier confirmation: Your status bar should display "Orange" or "Dauphin Telecom" with 5G/LTE signal within 60-90 seconds. On Pixel, check Settings > Network & Internet > SIMs — the travel SIM displays "Orange" as the active network.

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

Carrier Config

Carrier troubleshooting for Saint Martin

Orange

APN: "orange" — 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 "Orange" from the list. The phone locks onto Orange's 5G/LTE band and data resumes within 30 seconds.

Expected speed: Fastest 5G/LTE speeds in Saint Martin's urban areas

Common issue: If Orange 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 Saint Martin 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 Orange 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.

Dauphin Telecom

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 "Dauphin Telecom" from the list. The phone locks onto Dauphin Telecom's 5G/LTE band and data resumes within 30 seconds.

Expected speed: Reliable 5G/LTE coverage across Saint Martin's main cities

Common issue: Dauphin Telecom'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 Dauphin Telecom manually from the operator list.

Resolution: Restart your phone after adjusting network settings. Dauphin Telecom 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.

Dual SIM

Set up dual SIM before landing in Saint Martin

Data line setup

Configure the Saint Martin eSIM as primary data: Settings > Cellular > Cellular Data. Orange provides 5G/LTE coverage across Saint Martin'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 Saint Martin line. For voice calls over data — WhatsApp, FaceTime, Telegram — those route through the eSIM's data connection on Orange.

Emergency dialing

Dial 15/17/18/112 from your phone at any time — emergency calls bypass SIM restrictions and connect through any available network in Saint Martin. 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 Saint Martin eSIM for everything including WhatsApp and iMessage. Re-enable the home SIM at night for any pending SMS codes. Carry a Type C/E adapter for charging in Saint Martin.

Hotspot

Using personal hotspot in Saint Martin on eSIM data

Sharing data via hotspot is straightforward on most Saint Martin eSIM plans. Enable Personal Hotspot in Settings and connect your laptop or tablet. Orange's 5G/LTE network provides 5G/LTE speeds through hotspot, slightly below direct device connection 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 Saint Martin 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 Saint Martin eSIM hotspot.

Connect to Saint Martin's 5G network via eSIM

Saint Martin's Orange network provides limited 5G availability in select areas. Your eSIM connects to 5G automatically if your device supports it. To force 5G: iPhone — Settings > Cellular > Voice & Data > 5G On. Samsung — Settings > Connections > Mobile Networks > Network Mode > 5G/LTE. Choose "5G Auto" to balance speed and battery life. Outside 5G coverage areas, the phone falls back to LTE without interruption.

WiFi Backup

Activate your Saint Martin eSIM without reliable WiFi

Public WiFi in Saint Martin is moderate. 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 Saint Martin's main airport 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 Saint Martin to your multi-country eSIM setup

Multi-country travelers benefit from per-country eSIM profiles. A dedicated Saint Martin plan on Orange 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. Saint Martin plans start at $1.14 for 1GB.

Switching eSIM profiles between countries

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