Installation

How to set up the eSIM for United Kingdom

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., "United Kingdom 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., "United Kingdom 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

EE APN settings for eSIM

Automatic APN configuration

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

5G and LTE band selection

5G is available in United Kingdom (widespread 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 available in all major cities and many towns; rural gaps remain

Verification

Is your United Kingdom eSIM connected

Signal and network verification

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

"EE" 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 EE: approximately 180 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 Heathrow (LHR) / Gatwick (LGW) / Manchester (MAN) 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 United Kingdom profile to off. Leave it dormant until wheels touch the runway. EE 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 United Kingdom 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 United Kingdom eSIM. EE registers the profile in 30-45 seconds. You have maps, messaging, and ride-share access before the cabin door opens. The SIM counter from EE and Vodafone is in the arrivals hall — expect a 5-10 min; WHSmith and Dixons sell SIMs at most terminals wait and $10-25 for 10-30GB / 30 days for a tourist plan. Walk past it.

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. United Kingdom's emergency number is 999/112 — it works without data, but having your eSIM active means you can also share GPS coordinates with emergency services.

Carrier Config

Carrier troubleshooting for United Kingdom

EE

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

Expected speed: 162-180 Mbps in urban areas, 54-90 Mbps in rural coverage

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

Vodafone UK

APN: "live.vodafone.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 "Vodafone UK" from the list. The phone locks onto Vodafone UK's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 108-153 Mbps in cities, 36-72 Mbps outside metro areas

Common issue: Vodafone UK may show a signal bar but no data if the APN was not auto-configured. This happens on roughly 10-15% of United Kingdom eSIM activations. Enter APN "live.vodafone.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 Vodafone UK registration failures. Re-enable the United Kingdom eSIM after the reset completes.

Three UK

APN: "three.co.uk" — 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 "Three UK" from the list. The phone locks onto Three UK's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 108-153 Mbps in cities, 36-72 Mbps outside metro areas

Common issue: If Three UK 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 United Kingdom 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 Three UK 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.

Dual SIM

United Kingdom dual SIM guide: eSIM for data, home SIM for texts

Data line setup

Under Settings > Cellular > Cellular Data, choose the United Kingdom travel eSIM. Disable "Allow Cellular Data Switching" to prevent your phone from routing data through the home SIM when EE'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 United Kingdom eSIM is data-only: all apps, browsing, maps, and data-based messaging use EE's 5G/LTE 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 United Kingdom, dial 999/112 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 United Kingdom 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 EE continues normally through the eSIM. Pack an adapter for United Kingdom's Type G sockets.

Hotspot

Hotspot configuration for United Kingdom travelers

Your United Kingdom eSIM data can be shared via personal hotspot. iPhone: Settings > Personal Hotspot. Samsung: Settings > Connections > Mobile Hotspot and Tethering. The connected device sees EE's 5G/LTE signal at 108-144 Mbps typical through hotspot. 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 $2.84 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 United Kingdom plans. Nomad permits tethering on most tiers. If the hotspot toggle does not appear in Settings after installing your United Kingdom 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 United Kingdom hotspot.

Peak Season

United Kingdom peak season: Jun-Aug network advisory

Traveling to United Kingdom during Jun-Aug? Summer June-August is peak. Network congestion in tourist areas drops speeds to 72-108 Mbps during peak congestion on EE's network. Maps and messaging work without issue. Video calls and streaming may need WiFi backup. Install your eSIM before departure — airport SIM counters during peak season have queues twice the usual length.

Connect to United Kingdom's 5G network via eSIM

United Kingdom's EE network provides widespread 5G coverage across major cities and airports. 5G available in all major cities and many towns. 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. EE delivers 180 Mbps average on 5G bands. Outside 5G coverage areas, the phone falls back to LTE without interruption.

WiFi Backup

Setting up eSIM in United Kingdom: WiFi backup plan

WiFi in United Kingdom: excellent public WiFi (fast and widely available). Free WiFi in cafes, pubs, Tube stations, and most public spaces. 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 Heathrow (LHR) / Gatwick (LGW) / Manchester (MAN) 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: United Kingdom + other destinations

Planning a multi-country European trip (Schengen or cross-border rail) that includes United Kingdom? Install a dedicated eSIM for each country before you leave. Single-country plans connect to the primary local carrier (EE in United Kingdom) 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 United Kingdom. Set the United Kingdom eSIM as your data line and enable data roaming for that line specifically. EE picks up within 60-90 seconds. Keep all other profiles saved — they occupy no data until re-enabled.

Fixes

United Kingdom 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.

Slow speeds on EE

Expected: 180 Mbps. If speeds are noticeably lower: toggle airplane mode on and off. Move to a different area. Try forcing LTE if 5G is congested. During Jun-Aug speeds may drop in tourist areas.

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
