Installation

How to set up the eSIM for Slovenia

iOS installation (iPhone)

  1. Open Settings > Cellular > Add eSIM
  2. Select "Use QR Code"
  3. Scan the QR code from your Nomad confirmation email
  4. Label the plan (e.g., "Slovenia Travel")
  5. Set as cellular data line (not your default for calls)
  6. Do NOT enable data roaming yet
  7. 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)

  1. Open Settings > Connections > SIM Manager > Add eSIM
  2. Select "Download SIM" then "Scan QR code"
  3. Scan the QR code from your Nomad confirmation email
  4. Name the profile (e.g., "Slovenia Data")
  5. Set as mobile data SIM
  6. Do NOT enable data roaming yet
  7. Verify the plan in SIM manager

Manual installation (if QR fails)

If the QR code does not scan, use manual entry:

  1. Go to Settings > Cellular > Add eSIM
  2. Select "Enter Details Manually"
  3. Enter the SM-DP+ address from your provider email
  4. Enter the activation code
  5. 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

Telekom Slovenije network configuration

Automatic APN configuration

Most eSIM profiles auto-configure APN settings for Telekom Slovenije'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
FieldValue
APN NameFrom provider email
APNProvider-specific value
AuthenticationNone (most providers)
APN ProtocolIPv4/IPv6

Provider-specific APN values override Telekom Slovenije's carrier defaults. Always use the values from your provider, not generic carrier APNs.

5G and LTE band selection

5G is available in Slovenia (urban-only 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 in Ljubljana

Verification

Is your Slovenia eSIM connected

Signal and network verification

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

  • "Telekom Slovenije" 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 Telekom Slovenije: approximately 70 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 Ljubljana (LJU) with your eSIM

Before boarding

Your Slovenia eSIM installs in under two minutes. Do it the evening before departure over home WiFi. The profile stays dormant until you toggle it on after landing. Waiting until Ljubljana (LJU) creates two risks: captive portal WiFi blocking the download, and jet-lag mistakes during the Settings flow. Handle it while you are alert and connected.

During the flight

The flight is your final prep window. Go to Settings, confirm the Slovenia eSIM is listed and set as the data line, and verify your home SIM's data roaming is off. After landing, one toggle connects you to Telekom Slovenije's 5G/LTE network.

After landing

When the plane reaches the gate, disable airplane mode. The Slovenia eSIM connects to Telekom Slovenije within 45-90 seconds. Open Safari or Chrome and load any page — if it renders, your data is active. SIM counters in the arrivals hall charge a tourist premium ($8-12 for 5-10GB / 28 days) with a queue. Your eSIM is already active.

Leaving the airport

Head straight to ground transport. Your maps app already has signal on Telekom Slovenije's network. Book a ride from the terminal or follow transit directions without asking for WiFi passwords at an information desk. Slovenia's emergency number is 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 Slovenia

iPhone (iOS 17+)

  1. Open Settings > Cellular > Add eSIM > Use QR Code.
  2. Point the camera at the QR code from your provider's email. The profile downloads in 5-15 seconds on stable WiFi.
  3. Tap "Add Cellular Plan" when prompted. Label the plan "Slovenia Data" to distinguish it from your home line.
  4. Go to Settings > Cellular > Cellular Data and select the Slovenia eSIM as your active data line.
  5. Turn on Data Roaming for the Slovenia line only: Settings > Cellular > [Slovenia Data] > Data Roaming > On.

  7. Verify: open Safari and load any webpage. If the page renders, your Slovenia data is active at 70 Mbps average.

Carrier confirmation: Your status bar should display "Telekom Slovenije" or "A1 SI" with 5G/LTE signal within 60-90 seconds. On iPhone, check Settings > Cellular — the Slovenia line shows "Telekom Slovenije" under Network. If you see "5G" in the status bar, your phone has connected to Telekom Slovenije'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 Telekom Slovenije 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+)

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

Carrier confirmation: Your status bar should display "Telekom Slovenije" or "A1 SI" with 5G/LTE signal within 60-90 seconds. On Samsung, check Settings > Connections > SIM Manager — the travel SIM shows "Telekom Slovenije" as the connected network. A "5G" icon in the status bar confirms Telekom Slovenije'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 Telekom Slovenije. If the carrier does not appear, restart the device: hold Power + Volume Down until the restart menu appears.

Google Pixel (Android 14+)

  1. Open Settings > Network & Internet > SIMs > Add SIM > Download SIM.
  2. Scan the QR code from your eSIM provider's email. The profile downloads in under 15 seconds.
  3. Confirm the download and label the SIM "Slovenia Data" for identification.
  4. Set as mobile data SIM: Settings > Network & Internet > SIMs > Slovenia Data > Use for mobile data.

If it fails, reset network settings under Settings > System > Reset options > Reset Mobile, WiFi & Bluetooth.

Carrier Config

Carrier troubleshooting for Slovenia

Telekom Slovenije

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

Expected speed: 63-70 Mbps in urban areas, 21-35 Mbps in rural coverage

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

A1 SI

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 "A1 SI" from the list. The phone locks onto A1 SI's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 42-60 Mbps in cities, 14-28 Mbps outside metro areas

Common issue: A1 SI may show a signal bar but no data if the APN was not auto-configured. This happens on roughly 10-15% of Slovenia eSIM activations. Contact your eSIM provider for the correct APN string.

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 A1 SI registration failures. Re-enable the Slovenia eSIM after the reset completes.

Telemach

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

Expected speed: 42-60 Mbps in cities, 14-28 Mbps outside metro areas

Common issue: If Telemach 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 Slovenia 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 Telemach 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

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

Data line setup

Set the Slovenia eSIM as your cellular data line: Settings > Cellular > Cellular Data > select the travel eSIM. All web traffic, maps, and app data route through Telekom Slovenije's 5G/LTE network at $2.21 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 Slovenia eSIM's data connection through Telekom Slovenije.

Emergency dialing

Slovenia's emergency number is 112. 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 Slovenia eSIM active. Your home number goes to voicemail until you re-enable it. Slovenia outlets are Type C/F — bring an adapter and a portable charger.

Hotspot

Tethering and hotspot with your Slovenia eSIM

Most eSIM plans for Slovenia 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 Slovenia eSIM on Telekom Slovenije's 5G/LTE network. Hotspot throughput typically reaches 42-56 Mbps typical through hotspot. 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 Slovenia 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 Slovenia data allowance.

Registration

Skip Slovenia's SIM registration with eSIM

Slovenia mandates identity verification for all physical SIM purchases. ID required. The process at Ljubljana (LJU) involves a passport copy, a form, and a wait for carrier verification — 15-30 minutes minimum. Late-night arrivals face closed counters and no connectivity until morning. A prepaid eSIM requires zero documentation and activates on Telekom Slovenije's network the moment you land.

5G

Connect to Slovenia's 5G network via eSIM

Slovenia has limited 5G availability in select areas on Telekom Slovenije's network. 5G in Ljubljana. To use 5G with your eSIM, verify your phone supports 5G (iPhone 12 or later, Samsung Galaxy S21 or later, Pixel 5 or later). Go to Settings > Cellular > Cellular Data Options > Voice & Data > 5G Auto (iPhone) or Settings > Connections > Mobile Networks > Network Mode > 5G/LTE/3G/2G (Samsung). Average download speed on Telekom Slovenije's 5G: 70 Mbps. 5G drains battery 10-20% faster than LTE. Switch to LTE if battery life is more important than speed.

WiFi Backup

Setting up eSIM in Slovenia: WiFi backup plan

WiFi in Slovenia: good WiFi in hotels, malls, and cafes. 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 Ljubljana (LJU) 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: Slovenia + other destinations

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

Fixes

Common problems and fixes

"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 Telekom Slovenije

Expected: 70 Mbps. If speeds are noticeably lower: toggle airplane mode on and off. Move to a different area. Try forcing LTE if 5G is congested.
