Installation

Step-by-step: install your Greece eSIM

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., "Greece 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., "Greece 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

Network settings for Cosmote (OTE)

Automatic APN configuration

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

5G and LTE band selection

5G is available in Greece (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 Athens, Thessaloniki, and major islands; many islands still 4G only

Verification

After setup: testing your Greece eSIM

Signal and network verification

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

  • "Cosmote (OTE)" 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 Cosmote (OTE): approximately 102 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 Athens (ATH) / Heraklion (HER) / Thessaloniki (SKG) with your eSIM

Before boarding

Your Greece 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 Athens (ATH) / Heraklion (HER) / Thessaloniki (SKG) 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 Greece 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 Cosmote (OTE)'s 5G/LTE network.

After landing

When the plane reaches the gate, disable airplane mode. The Greece eSIM connects to Cosmote (OTE) within 30-45 seconds. Open Safari or Chrome and load any page — if it renders, your data is active. The SIM counter from Cosmote and Vodafone is in the arrivals hall — expect a 10-15 min wait and $10-20 for 10-20GB / 28 days for a tourist plan. Walk past it.

Leaving the airport

Head straight to ground transport. Your maps app already has signal on Cosmote (OTE)'s network. Book a ride from the terminal or follow transit directions without asking for WiFi passwords at an information desk. Greece'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 Greece

iPhone (iOS 17+)

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

Carrier Config

Carrier troubleshooting for Greece

Cosmote (OTE)

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

Expected speed: 92-102 Mbps in urban areas, 31-51 Mbps in rural coverage

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

Vodafone GR

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

Expected speed: 61-87 Mbps in cities, 20-41 Mbps outside metro areas

Common issue: Vodafone GR may show a signal bar but no data if the APN was not auto-configured. This happens on roughly 10-15% of Greece 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 GR registration failures. Re-enable the Greece eSIM after the reset completes.

Wind Hellas

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

Expected speed: 61-87 Mbps in cities, 20-41 Mbps outside metro areas

Common issue: If Wind Hellas 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 Greece 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 Wind Hellas 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

Greece dual SIM guide: eSIM for data, home SIM for texts

Data line setup

Under Settings > Cellular > Cellular Data, choose the Greece travel eSIM. Disable "Allow Cellular Data Switching" to prevent your phone from routing data through the home SIM when Cosmote (OTE)'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 Greece eSIM is data-only: all apps, browsing, maps, and data-based messaging use Cosmote (OTE)'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 Greece, dial 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 Greece 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 Cosmote (OTE) continues normally through the eSIM. Pack an adapter for Greece's Type C/F sockets.

Hotspot

Hotspot configuration for Greece travelers

Your Greece eSIM data can be shared via personal hotspot. iPhone: Settings > Personal Hotspot. Samsung: Settings > Connections > Mobile Hotspot and Tethering. The connected device sees Cosmote (OTE)'s 5G/LTE signal at 61-82 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 $2.21 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 Greece plans. Nomad permits tethering on most tiers. If the hotspot toggle does not appear in Settings after installing your Greece 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 Greece hotspot.

Registration

Skip Greece's SIM registration with eSIM

Greece mandates identity verification for all physical SIM purchases. Passport required for prepaid SIM purchase. The process at Athens (ATH) / Heraklion (HER) / Thessaloniki (SKG) 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 Cosmote (OTE)'s network the moment you land.

Peak Season

Greece peak season: Jun-Sep network advisory

Traveling to Greece during Jun-Sep? Summer peak for islands. Network congestion in tourist areas drops speeds to 41-61 Mbps during peak congestion on Cosmote (OTE)'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.

5G

Connect to Greece's 5G network via eSIM

Greece has limited 5G availability in select areas on Cosmote (OTE)'s network. 5G in Athens, Thessaloniki, and major islands. 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 Cosmote (OTE)'s 5G: 102 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 Greece: WiFi backup plan

WiFi in Greece: good WiFi in hotels, malls, and cafes. Free WiFi in most cafes and tavernas. 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 Athens (ATH) / Heraklion (HER) / Thessaloniki (SKG) 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: Greece + other destinations

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

Fixes

Setup troubleshooting for Greece

"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 Cosmote (OTE)

Expected: 102 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-Sep speeds may drop in tourist areas.
