Installation

Adding your Montenegro eSIM to your phone

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., "Montenegro 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., "Montenegro 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

APN setup for Montenegro eSIM

Automatic APN configuration

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

5G and LTE band selection

5G is available in Montenegro (limited 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 trials in Podgorica

Verification

Confirming your Montenegro eSIM setup

Signal and network verification

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

"m:tel CG" 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 m:tel CG: approximately 35 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 Podgorica (TGD) / Tivat (TIV) with your eSIM

Before boarding

Install your Montenegro eSIM at home the night before departure. Open Settings on your phone, add the eSIM profile via QR code over your home WiFi, and leave it toggled off. The plan clock does not start until m:tel CG's network registers the profile after you land. Airport WiFi at Podgorica (TGD) / Tivat (TIV) is unreliable for eSIM installation — boarding-gate networks often block the download entirely.

During the flight

Airplane mode stays on until you land. Use the flight time to verify your eSIM configuration: the Montenegro profile should be your active data line, and data roaming for that line should be ready to toggle on after touchdown.

After landing

Disable airplane mode after landing. Toggle the Montenegro eSIM on and enable data roaming for that line. m:tel CG's 5G/LTE network picks up your profile in 45-90 seconds. Verify by loading any webpage. SIM counters in the arrivals hall charge a tourist premium ($5-10 for 3-5GB / 15 days) with a queue. Your eSIM is already active.

Leaving the airport

Navigate the airport with live data. Check transit schedules, verify your hotel booking confirmation, and message your host — all before you exit the terminal. m:tel CG's 5G/LTE signal covers the airport grounds. Montenegro'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 Montenegro

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 "Montenegro Data" to distinguish it from your home line.
Go to Settings > Cellular > Cellular Data and select the Montenegro eSIM as your active data line.
Turn on Data Roaming for the Montenegro line only: Settings > Cellular > [Montenegro Data] > Data Roaming > On.
After landing at Podgorica (TGD) / Tivat (TIV), toggle the eSIM on. m:tel CG registers your profile in 60-90 seconds. APN settings auto-configure for most Montenegro eSIM plans on m:tel CG's network.
Verify: open Safari and load any webpage. If the page renders, your Montenegro data is active at 35 Mbps average.

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

After landing at Podgorica (TGD) / Tivat (TIV), enable the eSIM. m:tel CG's 5G/LTE network registers within 60-90 seconds. APN settings load automatically for most Montenegro eSIM plans on m:tel CG's network.
Verify: open Chrome and load any page. Data flowing confirms your Montenegro eSIM is active.

Carrier confirmation: Your status bar should display "m:tel CG" or "Crnogorski Telekom" with 5G/LTE signal within 60-90 seconds. On Samsung, check Settings > Connections > SIM Manager — the travel SIM shows "m:tel CG" as the connected network. A "5G" icon in the status bar confirms m:tel CG'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 m:tel CG. 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 "Montenegro Data" for identification.
Set as mobile data SIM: Settings > Network & Internet > SIMs > Montenegro Data > Use for mobile data.
Enable roaming: Settings > Network & Internet > SIMs > Montenegro Data > Roaming > On.
After landing at Podgorica (TGD) / Tivat (TIV), enable the profile. m:tel CG connects within 60-90 seconds. APN settings self-configure on Pixel devices for most Montenegro plans.
Open Chrome and load any page to verify data connectivity on m:tel CG's 5G/LTE network.

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

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

Carrier Config

Carrier troubleshooting for Montenegro

m:tel CG

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

Expected speed: 32-35 Mbps in urban areas, 11-18 Mbps in rural coverage

Common issue: m:tel CG'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 m:tel CG manually from the operator list.

Resolution: Restart your phone after adjusting network settings. m:tel CG 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.

Crnogorski Telekom

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

Expected speed: 21-30 Mbps in cities, 7-14 Mbps outside metro areas

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

One Montenegro

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

Expected speed: 21-30 Mbps in cities, 7-14 Mbps outside metro areas

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

Dual SIM

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

Data line setup

Set the Montenegro eSIM as your cellular data line: Settings > Cellular > Cellular Data > select the travel eSIM. All web traffic, maps, and app data route through m:tel CG's 5G/LTE network at $3.49 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 Montenegro eSIM's data connection through m:tel CG.

Emergency dialing

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

Hotspot

Tethering and hotspot with your Montenegro eSIM

Most eSIM plans for Montenegro 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 Montenegro eSIM on m:tel CG's 5G/LTE network. Hotspot throughput typically reaches 21-28 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 Montenegro 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 Montenegro data allowance.

Registration

Skip Montenegro's SIM registration with eSIM

Buying a physical SIM in Montenegro requires Passport required. At Podgorica (TGD) / Tivat (TIV), the registration process at m:tel CG's counter takes 15-30 minutes: passport scan, photo capture, form completion. Some carriers require biometric verification (fingerprint or face scan). An eSIM purchased online before departure skips this entire process. No documents, no counter, no registration delay.

Connect to Montenegro's 5G network via eSIM

Montenegro has limited 5G availability in select areas on m:tel CG's network. 5G trials in Podgorica. 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 m:tel CG's 5G: 35 Mbps. 5G drains battery 10-20% faster than LTE. Switch to LTE if battery life is more important than speed.

WiFi Backup

WiFi and eSIM activation in Montenegro

Montenegro has good WiFi in hotels, malls, and cafes. The best approach: install your eSIM at home over your own WiFi before departure. The QR code scan transfers about 500 KB of profile data — it needs a clean connection, not speed. Airport WiFi at Podgorica (TGD) / Tivat (TIV) uses captive portals that can interrupt the eSIM download. Install at home, travel with confidence.

Activating without WiFi

If you cannot scan the QR code, use manual entry. Your eSIM provider's confirmation email contains an SM-DP+ activation address and activation code. On iPhone: Settings > Cellular > Add eSIM > Enter Details Manually. On Samsung: Settings > Connections > SIM Manager > Add eSIM > Enter Activation Code. Enter the SM-DP+ address and code exactly as shown. This method uses your existing data connection (home carrier or WiFi) and does not require a camera.

Multi-Country

Montenegro eSIM on a multi-country trip

If Montenegro is one stop on a multi-country European trip (Schengen or cross-border rail), install all country eSIMs before departure. Most phones store 8 or more eSIM profiles. Label each one clearly: "Montenegro Data," "France Data," etc. At each border, disable the previous country's eSIM and enable the next one. The switch takes 30 seconds under Settings > Cellular. A single-country Montenegro plan on m:tel CG's 5G/LTE network delivers better local coverage than a multi-country regional eSIM — starting at $3.49 for 1GB.

Switching eSIM profiles between countries

At the Montenegro border, open Settings > Cellular (iPhone) or SIM Manager (Samsung). Disable your previous eSIM. Enable the Montenegro profile and set it as the active data line. Turn on data roaming for the Montenegro line. m:tel CG's 5G/LTE network connects within 60-90 seconds. Do not delete the previous eSIM — you may need it on the return leg.

Fixes

When your Montenegro eSIM does not work

"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 m:tel CG

Expected: 35 Mbps. If speeds are noticeably lower: toggle airplane mode on and off. Move to a different area. Try forcing LTE if 5G is congested.

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
