Installation

How to set up the eSIM for Antigua and Barbuda

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., "Antigua and Barbuda 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., "Antigua and Barbuda 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

Network settings for FLOW

Automatic APN configuration

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

Verification

Is your Antigua and Barbuda eSIM connected

Signal and network verification

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

"FLOW" 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 Antigua and Barbuda's main airport with your eSIM

Before boarding

Add your Antigua and Barbuda 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 Antigua and Barbuda's main airport 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 Antigua and Barbuda 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 Antigua and Barbuda eSIM under Settings and turn on data roaming for that specific line. FLOW connects in 60-90 seconds. Your first notification pops up before the aisle clears. SIM counter availability at Antigua and Barbuda's main airport varies by terminal and time of day. Your eSIM eliminates that variable entirely.

Leaving the airport

Use your Antigua and Barbuda 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. Antigua and Barbuda's emergency number is 911/999 — 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 Antigua and Barbuda

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 "Antigua and Barbuda Data" to distinguish it from your home line.
Go to Settings > Cellular > Cellular Data and select the Antigua and Barbuda eSIM as your active data line.
Turn on Data Roaming for the Antigua and Barbuda line only: Settings > Cellular > [Antigua and Barbuda Data] > Data Roaming > On.
After landing at Antigua and Barbuda's main airport, toggle the eSIM on. FLOW registers your profile in 60-90 seconds. APN settings auto-configure for most Antigua and Barbuda eSIM plans on FLOW's network.
Verify: open Safari and load any webpage. If the page renders, your Antigua and Barbuda data is active at 4G LTE speeds.

Carrier confirmation: Your status bar should display "FLOW" or "Digicel" with 4G signal within 60-90 seconds. On iPhone, check Settings > Cellular — the Antigua and Barbuda line shows "FLOW" 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 FLOW 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.
Tap "Add" when the carrier profile loads. Label it "Antigua and Barbuda Data" under SIM Manager for clarity.
Set the Antigua and Barbuda eSIM as your mobile data SIM: Settings > Connections > SIM Manager > Mobile Data > select Antigua and Barbuda eSIM.
Enable Data Roaming: Settings > Connections > Mobile Networks > Data Roaming > On (for the travel SIM only).
After landing at Antigua and Barbuda's main airport, enable the eSIM. FLOW's 4G network registers within 60-90 seconds. APN settings load automatically for most Antigua and Barbuda eSIM plans on FLOW's network.
Verify: open Chrome and load any page. Data flowing confirms your Antigua and Barbuda eSIM is active.

Carrier confirmation: Your status bar should display "FLOW" or "Digicel" with 4G signal within 60-90 seconds. On Samsung, check Settings > Connections > SIM Manager — the travel SIM shows "FLOW" 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 FLOW. 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 "Antigua and Barbuda Data" for identification.
Set as mobile data SIM: Settings > Network & Internet > SIMs > Antigua and Barbuda Data > Use for mobile data.
Enable roaming: Settings > Network & Internet > SIMs > Antigua and Barbuda Data > Roaming > On.
After landing at Antigua and Barbuda's main airport, enable the profile. FLOW connects within 60-90 seconds. APN settings self-configure on Pixel devices for most Antigua and Barbuda plans.
Open Chrome and load any page to verify data connectivity on FLOW's 4G network.

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

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

Carrier Config

Carrier troubleshooting for Antigua and Barbuda

FLOW

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

Expected speed: Fastest 4G speeds in Antigua and Barbuda's urban areas

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

Digicel

APN: "web.digicelgy.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 "Digicel" from the list. The phone locks onto Digicel's 4G band and data resumes within 30 seconds.

Expected speed: Reliable 4G coverage across Antigua and Barbuda's main cities

Common issue: Digicel may show a signal bar but no data if the APN was not auto-configured. This happens on roughly 10-15% of Antigua and Barbuda eSIM activations. Enter APN "web.digicelgy.com" 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 Digicel registration failures. Re-enable the Antigua and Barbuda eSIM after the reset completes.

Dual SIM

Antigua and Barbuda dual SIM guide: eSIM for data, home SIM for texts

Data line setup

Under Settings > Cellular > Cellular Data, choose the Antigua and Barbuda travel eSIM. Disable "Allow Cellular Data Switching" to prevent your phone from routing data through the home SIM when FLOW's signal dips temporarily. A brief signal dip is normal when moving between cell towers — your home carrier's roaming rates are not a reasonable fallback.

Calls and SMS

Maintain your home SIM for voice and SMS. Your number does not change. Authentication codes still arrive by text. The Antigua and Barbuda eSIM is data-only: all apps, browsing, maps, and data-based messaging use FLOW's 4G connection. This split keeps costs controlled — home carrier voice rates are typically lower than international data roaming.

Emergency dialing

Emergency calls work on any active SIM, even without a data plan. In Antigua and Barbuda, dial 911/999 from either SIM line. If your eSIM has data active, you can also share your GPS location with emergency services via messaging apps or the phone's built-in emergency SOS feature.

Battery impact

Dual SIM operation increases battery consumption by roughly 10-15%. Both the home SIM and Antigua and Barbuda eSIM maintain active connections to separate towers. To conserve battery, switch the home SIM to airplane mode when you do not need incoming calls. Data on FLOW continues normally through the eSIM. Pack an adapter for Antigua and Barbuda's Type A/B sockets.

Hotspot

Hotspot configuration for Antigua and Barbuda travelers

Your Antigua and Barbuda eSIM data can be shared via personal hotspot. iPhone: Settings > Personal Hotspot. Samsung: Settings > Connections > Mobile Hotspot and Tethering. The connected device sees FLOW's 4G signal at 4G speeds through hotspot, slightly below direct device connection. Data consumption through hotspot runs 1.5-2x higher than direct phone use because laptop browsers load full desktop sites. Budget accordingly — a 1GB plan at $10.98 supports 2-3 days of moderate laptop use.

Provider restrictions

Provider-level restrictions: Airalo includes hotspot on nearly all fixed-data plans. Saily allows tethering by default. Holafly restricts it on unlimited Antigua and Barbuda plans. Nomad permits tethering on most tiers. If the hotspot toggle does not appear in Settings after installing your Antigua and Barbuda eSIM, the plan does not support it — upgrade or switch providers.

Data impact

Tethered devices consume data faster than direct phone use. A laptop loading desktop websites uses 2-3x the data of mobile sites. Video streaming at 720p burns 1.5 GB per hour; at 1080p, closer to 3 GB. Cloud sync (Google Drive, Dropbox, iCloud) runs in the background and can drain 500 MB-1 GB in a few hours without visible activity. Pause cloud sync before connecting a laptop to your Antigua and Barbuda hotspot.

WiFi Backup

Setting up eSIM in Antigua and Barbuda: WiFi backup plan

WiFi in Antigua and Barbuda: moderate WiFi in urban areas; spotty in rural regions. eSIM installation requires a brief WiFi connection for the QR code scan (under 1 MB of data). Hotel WiFi works, but home WiFi before departure is the safest option. Captive portals at Antigua and Barbuda's main airport and public hotspots sometimes block the carrier server the eSIM download needs.

Activating without WiFi

Manual activation fallback: every eSIM order includes an SM-DP+ server address and an activation code in the confirmation email. Instead of scanning the QR code, enter these values manually. iPhone: Settings > Cellular > Add eSIM > Enter Details Manually. Samsung: Settings > Connections > SIM Manager > Add eSIM > Enter Code. This works over any data connection, including your home carrier's mobile data. The transfer is under 1 MB.

Multi-Country

Managing eSIM profiles: Antigua and Barbuda + other destinations

Planning a multi-country itinerary that includes Antigua and Barbuda? Install a dedicated eSIM for each country before you leave. Single-country plans connect to the primary local carrier (FLOW in Antigua and Barbuda) and deliver better speeds than regional eSIMs that route through roaming agreements. Your phone holds up to 8 eSIM profiles — switching between them at each border takes 30 seconds. Label each profile with the country name for quick identification.

Switching eSIM profiles between countries

Switching eSIMs at the border: go to Settings, find your SIM/eSIM list, turn off the previous country's profile, and enable Antigua and Barbuda. Set the Antigua and Barbuda eSIM as your data line and enable data roaming for that line specifically. FLOW picks up within 60-90 seconds. Keep all other profiles saved — they occupy no data until re-enabled.

Fixes

Antigua and Barbuda eSIM installation problems

"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.
