Installation

Adding your Mongolia 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., "Mongolia 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 (Google Pixel)

Open Settings > Network & Internet > Add eSIM
Select "Download a SIM instead" then scan
Scan the QR code from your Nomad confirmation email
Name the profile (e.g., "Mongolia 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 and band settings for Mongolia

Automatic APN configuration

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

Verification

Confirming your Mongolia eSIM setup

Signal and network verification

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

"Mobicom" 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: 4G LTE (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 Mongolia's main airport with your eSIM

Before boarding

Install your Mongolia 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 Mobicom's network registers the profile after you land. Airport WiFi at Mongolia's main airport 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 Mongolia 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 Mongolia eSIM on and enable data roaming for that line. Mobicom's 4G network picks up your profile in 60-90 seconds. Verify by loading any webpage. SIM counter availability at Mongolia's main airport varies by terminal and time of day. Your eSIM eliminates that variable entirely.

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. Mobicom's 4G signal covers the airport grounds. Mongolia's emergency number is 102/103/105 — 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 Mongolia

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 "Mongolia Data" to distinguish it from your home line.
Go to Settings > Cellular > Cellular Data and select the Mongolia eSIM as your active data line.
Turn on Data Roaming for the Mongolia line only: Settings > Cellular > [Mongolia Data] > Data Roaming > On.
After landing at Mongolia's main airport, toggle the eSIM on. Mobicom registers your profile in 60-90 seconds. APN settings auto-configure for most Mongolia eSIM plans on Mobicom's network.
Verify: open Safari and load any webpage. If the page renders, your Mongolia data is active at 4G LTE speeds.

Carrier confirmation: Your status bar should display "Mobicom" or "Unitel" with 4G signal within 60-90 seconds. On iPhone, check Settings > Cellular — the Mongolia line shows "Mobicom" under Network. The "4G" indicator confirms your connection type.

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 Mobicom 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).

Enable Data Roaming: Settings > Connections > Mobile Networks > Data Roaming > On (for the travel SIM only).
After landing at Mongolia's main airport, enable the eSIM. Mobicom's 4G network registers within 60-90 seconds. APN settings load automatically for most Mongolia eSIM plans on Mobicom's network.
Verify: open Chrome and load any page. Data flowing confirms your Mongolia eSIM is active.

Carrier confirmation: Your status bar should display "Mobicom" or "Unitel" with 4G signal within 60-90 seconds. On Samsung, check Settings > Connections > SIM Manager — the travel SIM shows "Mobicom" as the connected network. The connection type shows as "4G".

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 Mobicom. 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 "Mongolia Data" for identification.
Set as mobile data SIM: Settings > Network & Internet > SIMs > Mongolia Data > Use for mobile data.
Enable roaming: Settings > Network & Internet > SIMs > Mongolia Data > Roaming > On.
After landing at Mongolia's main airport, enable the profile. Mobicom connects within 60-90 seconds. APN settings self-configure on Pixel devices for most Mongolia plans.
Open Chrome and load any page to verify data connectivity on Mobicom's 4G network.

Carrier confirmation: Your status bar should display "Mobicom" or "Unitel" with 4G signal within 60-90 seconds. On Pixel, check Settings > Network & Internet > SIMs — the travel SIM displays "Mobicom" as the active network.

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

Carrier Config

Carrier troubleshooting for Mongolia

Mobicom

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 "Mobicom" from the list. The phone locks onto Mobicom's 4G band and data resumes within 30 seconds.

Expected speed: Fastest 4G speeds in Mongolia's urban areas

Common issue: Mobicom'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 Mobicom manually from the operator list.

Resolution: Restart your phone after adjusting network settings. Mobicom 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.

Unitel

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 "Unitel" from the list. The phone locks onto Unitel's 4G band and data resumes within 30 seconds.

Expected speed: Reliable 4G coverage across Mongolia's main cities

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

Skytel

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 "Skytel" from the list. The phone locks onto Skytel's 4G band and data resumes within 30 seconds.

Expected speed: Reliable 4G coverage across Mongolia's main cities

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

Dual SIM

Running two SIMs in Mongolia: data line vs call line

Data line setup

Open Settings > Cellular and tap "Cellular Data." Select the Mongolia eSIM. All data now routes through Mobicom's local network at local rates. Do not enable "Allow Cellular Data Switching" — that setting lets the phone fall back to your home SIM for data, which triggers international roaming fees without warning.

Calls and SMS

The home SIM stays on for calls and verification texts. When someone dials your regular number, it rings normally. Standard SMS charges from your home carrier may apply for receiving texts abroad — check your plan. All internet-based communication routes through Mobicom's data network on the Mongolia eSIM.

Emergency dialing

Emergency services in Mongolia are reached at 102/103/105. Both your home SIM and the travel eSIM can place this call. Data from the eSIM adds GPS location sharing, real-time translation for language barriers, and the ability to look up your embassy's local address and phone number.

Battery impact

Running two SIMs draws 10-15% more battery per day than a single SIM. Both radios maintain separate network connections. If your battery runs low during the day, disable the home SIM temporarily under Settings > Cellular — the Mongolia eSIM is the priority line for data. Re-enable the home SIM when you reach WiFi at your hotel. Mongolia uses Type C/E outlets — carry the right adapter.

Hotspot

Share your Mongolia eSIM data with other devices

Personal hotspot works with most Mongolia eSIM plans from major providers. Enable it under your phone's settings. The hotspot shares your Mobicom 4G connection with nearby devices via WiFi, Bluetooth, or USB. WiFi tethering has the widest range (roughly 10 meters) but uses more battery. USB tethering charges your phone while sharing data — ideal for laptop sessions. Expect 4G speeds through hotspot, slightly below direct device connection on the connected device.

Provider restrictions

Hotspot availability is a plan feature, not a country restriction. Most fixed-data Mongolia plans support tethering. Unlimited plans are the exception — carriers throttle or block hotspot on unlimited tiers to manage network load on Mobicom's infrastructure. If you need hotspot, buy a fixed-data plan with an explicit hotspot label.

Data impact

Tethering multiplies data use. A single Zoom call uses 300-500 MB/hour. Slack with screen sharing adds 200-400 MB/hour. Background cloud sync on a connected laptop can consume 500 MB-1 GB without any visible activity. Before hotspotting in Mongolia, disable auto-sync and set video calls to audio-only when possible — that drops consumption by 70%.

WiFi Backup

WiFi and eSIM activation in Mongolia

Mongolia has moderate WiFi in urban areas; spotty in rural regions. 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 Mongolia's main airport 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

Mongolia eSIM on a multi-country trip

If Mongolia is one stop on a multi-stop Asian itinerary, install all country eSIMs before departure. Most phones store 8 or more eSIM profiles. Label each one clearly: "Mongolia 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 Mongolia plan on Mobicom's 4G network delivers better local coverage than a multi-country regional eSIM — starting at $5.76 for 1GB.

Switching eSIM profiles between countries

At the Mongolia border, open Settings > Cellular (iPhone) or SIM Manager (Samsung). Disable your previous eSIM. Enable the Mongolia profile and set it as the active data line. Turn on data roaming for the Mongolia line. Mobicom's 4G network connects within 60-90 seconds. Do not delete the previous eSIM — you may need it on the return leg.

Fixes

What to do when setup fails

"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.
