Installation

Setting up your Puerto Rico eSIM profile

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., "Puerto Rico 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., "Puerto Rico 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

Configuring APN for Puerto Rico data

Automatic APN configuration

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

Verification

Testing data on T-Mobile's network

Signal and network verification

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

"T-Mobile" 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 Puerto Rico's main airport with your eSIM

Before boarding

Add your Puerto Rico 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 Puerto Rico'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 Puerto Rico 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 Puerto Rico eSIM under Settings and turn on data roaming for that specific line. T-Mobile connects in 60-90 seconds. Your first notification pops up before the aisle clears. SIM counter availability at Puerto Rico's main airport varies by terminal and time of day. Your eSIM eliminates that variable entirely.

Leaving the airport

Use your Puerto Rico 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. Puerto Rico'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 Puerto Rico

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 "Puerto Rico Data" to distinguish it from your home line.
Go to Settings > Cellular > Cellular Data and select the Puerto Rico eSIM as your active data line.
Turn on Data Roaming for the Puerto Rico line only: Settings > Cellular > [Puerto Rico Data] > Data Roaming > On.
After landing at Puerto Rico's main airport, toggle the eSIM on. T-Mobile 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: "fast.t-mobile.com". Leave username and password blank.
Verify: open Safari and load any webpage. If the page renders, your Puerto Rico data is active at 5G speeds.

Carrier confirmation: Your status bar should display "T-Mobile" or "AT&T" with 5G/LTE signal within 60-90 seconds. On iPhone, check Settings > Cellular — the Puerto Rico line shows "T-Mobile" under Network. If you see "5G" in the status bar, your phone has connected to T-Mobile'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 T-Mobile 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).

Carrier confirmation: Your status bar should display "T-Mobile" or "AT&T" with 5G/LTE signal within 60-90 seconds. On Samsung, check Settings > Connections > SIM Manager — the travel SIM shows "T-Mobile" as the connected network. A "5G" icon in the status bar confirms T-Mobile'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 T-Mobile. 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 "Puerto Rico Data" for identification.

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

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

Carrier Config

Carrier troubleshooting for Puerto Rico

T-Mobile

APN: "fast.t-mobile.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 "T-Mobile" from the list. The phone locks onto T-Mobile's 5G/LTE band and data resumes within 30 seconds.

Expected speed: Fastest 5G/LTE speeds in Puerto Rico's urban areas

Common issue: If T-Mobile 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 Puerto Rico 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 T-Mobile 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.

AT&T

APN: "phone" — 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 "AT&T" from the list. The phone locks onto AT&T's 5G/LTE band and data resumes within 30 seconds.

Expected speed: Reliable 5G/LTE coverage across Puerto Rico's main cities

Common issue: AT&T'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 AT&T manually from the operator list.

Resolution: Restart your phone after adjusting network settings. AT&T 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.

Claro PR

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

Expected speed: Reliable 5G/LTE coverage across Puerto Rico's main cities

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

Dual SIM

Set up dual SIM before landing in Puerto Rico

Data line setup

Configure the Puerto Rico eSIM as primary data: Settings > Cellular > Cellular Data. T-Mobile provides 5G/LTE coverage across Puerto Rico'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 Puerto Rico line. For voice calls over data — WhatsApp, FaceTime, Telegram — those route through the eSIM's data connection on T-Mobile.

Emergency dialing

Dial 911 from your phone at any time — emergency calls bypass SIM restrictions and connect through any available network in Puerto Rico. 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 Puerto Rico eSIM for everything including WhatsApp and iMessage. Re-enable the home SIM at night for any pending SMS codes. Carry a Type A/B adapter for charging in Puerto Rico.

Hotspot

Using personal hotspot in Puerto Rico on eSIM data

Sharing data via hotspot is straightforward on most Puerto Rico eSIM plans. Enable Personal Hotspot in Settings and connect your laptop or tablet. T-Mobile'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 Puerto Rico 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 Puerto Rico eSIM hotspot.

Connect to Puerto Rico's 5G network via eSIM

T-Mobile offers limited 5G availability in select areas in Puerto Rico. 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+). "5G Auto" on iPhone conserves battery by falling back to LTE when 5G speed is not needed.

WiFi Backup

Activate your Puerto Rico eSIM without reliable WiFi

Public WiFi in Puerto Rico 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 Puerto Rico'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 Puerto Rico to your multi-country eSIM setup

Multi-country travelers benefit from per-country eSIM profiles. A dedicated Puerto Rico plan on T-Mobile 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. Puerto Rico plans start at $3.08 for 1GB.

Switching eSIM profiles between countries

To switch from a previous country's eSIM to Puerto Rico: iPhone — Settings > Cellular, tap the old country's eSIM, toggle "Turn On This Line" off. Tap the Puerto Rico eSIM, toggle it on, and confirm it is set as Cellular Data. Samsung — Settings > Connections > SIM Manager, disable the old SIM, enable the Puerto Rico SIM, set it as Mobile Data. T-Mobile registers within 60-90 seconds.

Fixes

Fixing installation issues for Puerto Rico

"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.
