Fast, pragmatic steps to add and troubleshoot a NexaEsim Andorra eSIM on iPhone (QR or manual SM‑DP+), plus Android fallback, roaming checks and arrival checklist.
Quick Answer
If you need a working eSIM in Andorra now: open Settings > Cellular > Add eSIM, scan the QR from your NexaEsim order or enter the SM‑DP+ details manually, label the new line and set it as your Cellular Data line; enable Data Roaming if mobile data doesn’t start. If the QR fails, enter SM‑DP+, ICCID and activation code from your order email and restart the iPhone — that resolves most activations.
What this guide covers
Practical, step‑by‑step fixes to install and activate a NexaEsim Andorra plan on iPhone (QR and manual SM‑DP+ flows), a short Android fallback, prioritized troubleshooting, how to set the eSIM as your data line, top‑up and invoice tips, and arrival checklist. If you're ready to buy or want pre‑activation options, see NexaEsim Andorra plans: NexaEsim Andorra plans.
Common reasons your eSIM in Andorra is not connecting
- Missing or expired activation schedule (pre‑activate vs start‑on‑arrival mismatch).
- QR code not scanned correctly or PDF/image not accessible offline at arrival.
- iPhone iOS version or device model not compatible (check device compatibility before buying).
- Cellular Data line still set to your home SIM instead of the eSIM.
- Data Roaming disabled or APN required for the roaming partner network.
- Weak local signal (mountain valleys) or temporary network congestion.
Quick fix on iPhone
Step 1 — Verify prerequisites
- Check iPhone model and iOS version (iOS >= required minimum). If unsure, back up device first and update iOS via Settings > General > Software Update.
- Ensure you have the NexaEsim order email locally available (QR image or SM‑DP+ block) and that your phone is unlocked if required by your carrier.
Step 2 — Install via QR (primary path)
- Open Settings > Cellular > Add Cellular Plan.
- Use the camera to scan the QR code from your NexaEsim order email. If prompted, confirm Add Cellular Plan.
- Label the plan when prompted (e.g., “Andorra”) so you can switch easily later.
- Go to Settings > Cellular > Cellular Data and select the new eSIM as your data line.
- If you need calls on your home number, keep Primary (physical SIM) as the default for voice and SMS as desired in Settings > Cellular > Default Voice Line.
Step 3 — Manual install (SM‑DP+ fallback)
If the QR won’t scan or you only have text details, use Manual Install:
- Settings > Cellular > Add Cellular Plan > Enter Details Manually.
- Copy the SM‑DP+ address, activation code and ICCID exactly from your NexaEsim order email into the fields shown.
- Confirm, label the plan, then set Cellular Data to the eSIM (Settings > Cellular > Cellular Data).
- Restart the phone after manual entry if activation is "pending".
Quick verification
- Open a web page (http://example.com) — if it loads, data is active.
- Check Settings > Cellular > Cellular Plans — profile should show as Active and your label.
- If activation was pre‑scheduled, confirm the activation date/time in your order email before troubleshooting further.
Quick fix on Samsung and Google Pixel
Android steps are included as a fallback if you switch devices; these are concise checks that match the same logic used on iPhone.
Samsung (One UI)
- Settings > Connections > SIM card manager > Add mobile plan > Scan QR or enter activation details manually.
- Set the eSIM as Mobile data in SIM card manager.
- Enable Data Roaming in Settings > Connections > Mobile networks.
Google Pixel (Android)
- Settings > Network & internet > Mobile network > + > Download a SIM instead > Scan QR or enter SM‑DP+ details.
- Select the profile as your mobile data source and enable Data Roaming if required.
APN, roaming, and manual network checks
If the profile installs but you have no data, these checks fix most issues:
- Enable Data Roaming: Settings > Cellular > Cellular Data Options > Data Roaming (toggle on).
- Manual network selection: Settings > Cellular > Network Selection > turn off automatic and pick the strongest available partner network (choose the one with better signal bars).
- APN: iOS usually configures APN automatically; if required, go to Settings > Cellular > Cellular Data Network and enter APN details from NexaEsim support.
- Airplane mode reset: Toggle Airplane Mode on for 10 seconds and off again to force a fresh network attach.
Pre‑activate vs Start‑on‑arrival (comparison)
| Pre‑activate | Start‑on‑arrival |
|---|---|
| Install now; plan becomes active on the scheduled start date so you are online on landing (recommended for airports). | Install now but activation only starts when you choose the start date or when you land — useful if you want to save days. |
| Pros: be online immediately on arrival, avoid airport queues. | Pros: you don’t begin using validity until you arrive. |
| Cons: schedule carefully — activation date is fixed at purchase. | Cons: if you forget to start it on arrival you may not be online until you do. |
Order email checklist: QR, SM‑DP+ address, ICCID, activation schedule, top‑up link and invoiceable receipt option. Keep a screenshot or printed copy of the QR/SM‑DP+ so it’s available offline at the airport.
Local carrier selection, weather disruptions, and visa/entry reminders for Andorra
- Do not rely on a single network in mountain areas — use manual network selection to pick the strongest partner when signal fluctuates.
- Andorra has a mountain climate; valleys and remote passes can have weaker coverage — plan for offline maps or an extra data buffer when travelling to high/remote areas.
- Visa and entry rules change — always verify visa/entry requirements with official government, embassy or airline sources before travel.

Tips for stable data while moving between cities in Andorra
- Keep Cellular Data set to the eSIM and use your home SIM only for voice if you want to receive calls on your primary number.
- Top up before you need it — network congestion can slow purchase or top‑up flows during peak times. See top‑up options and invoiceable receipts via your NexaEsim account or order email.
- If you're switching between valleys and towns, set manual network selection to the strongest partner in each area rather than relying on automatic handover.
- Carry a small battery pack — GPS and mobile data combined drain phones faster in roaming conditions.
Troubleshooting — prioritized quick fixes
- Re‑scan QR or re‑enter SM‑DP+ details manually (most common fix).
- Enable Data Roaming and toggle Cellular Data off/on for the eSIM line.
- Restart the iPhone; if still pending, remove the eSIM profile and install again from the saved QR/SM‑DP+ (do not delete if you need to preserve billing records without backup).
- Reset Network Settings: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings (this removes saved Wi‑Fi and VPN profiles — use as last resort).
- If none of the above work, gather: order ID, device model and iOS version, screenshots of error messages and Cellular Plans screen, and contact NexaEsim support (see closing CTA). Include the SM‑DP+ block from your order if available.
