eSIM not working in Portugal
Your Drift Europa eSIM has no data in Portugal? Here is the real fix, step by step, iPhone and Android, with Portugal operator APN reference.
Networks in Portugal
Portugal has 3 major operators, all compatible with travel eSIMs:
| Operator | Coverage | Technology |
|---|---|---|
| MEO | 1er réseau (Altice Portugal) | 4G/5G |
| NOS | 2e réseau | 4G/5G |
| Vodafone PT | 3e réseau | 4G/5G |
Your eSIM connects to one of these networks (most often MEO). 4G coverage spans the large majority of tourist and urban areas.
Diagnosis in 5 steps (in this order)
Work through these before anything else. Nine times out of ten, the fix is in this list.
Steps 2 and 3 fix the large majority of cases. Data roaming is required for any travel eSIM. It does not add charges on a Drift Europa plan.
Airplane mode as a diagnostic tool
Toggling airplane mode forces the phone to detach from the network and search fresh. It is faster than a full restart and clears most handover issues (when the phone stays attached to a ghost signal after a long flight). If after the toggle you see the operator name on screen but still have no data, the issue is almost certainly roaming (step 2) or data line (step 3).
Signal bars vs. data
A common trap: you see signal bars but nothing loads. Bars mean the phone detects the network, not that it is authorized to exchange data. That is exactly what happens with roaming off: signal is there, but the network refuses your data packets. Turn roaming on and data resumes.
APN in Portugal: do you need to set it?
No, in 99% of cases. Your travel eSIM sets its own APN automatically via the installed profile.
Do not enter your home operator's APN or a MEO APN found online into the eSIM line. Those are APNs for local physical SIMs, not travel eSIMs. Entering one overwrites the profile's APN and breaks your data instead of fixing it.
For reference only (do NOT enter these on your eSIM line):
| Operator | Primary APN | Alt APN | Note |
|---|---|---|---|
| MEO | internet | meo.pt | 1er réseau (Altice Portugal) |
| NOS | internet | nos.pt | 2e réseau |
| Vodafone PT | internet.vodafone.pt | net2.vodafone.pt | 3e réseau |
Manual APN entry only if support asks with a specific value. Full procedure: Do I need to set an APN?
Country-specific notes for Portugal
Azores and Madeira
Madeira (Funchal, south coast) has good 4G. Levada hiking trails in the interior may have weaker signal. The main Azores islands (Sao Miguel, Terceira) have decent coverage; smaller islands (Flores, Corvo) are patchier. MEO has the best island coverage.
Algarve and interior
The tourist Algarve is very well covered. Interior Portugal (Alentejo, Tras-os-Montes) is more rural but tourist areas (Douro, Evora) remain covered.

FAQ
Why does my eSIM have no signal in Portugal?
Most likely data roaming is not turned on for the eSIM line. Enable it in your mobile data settings. If you see signal bars but no data, also check that the eSIM is set as your data line.
What APN should I use for my eSIM in Portugal?
None. The eSIM sets its own APN automatically. Do not enter an APN for MEO or any other local operator.
Do I need to enable roaming to use my eSIM in Portugal?
Yes, it is required. Data roaming must be ON for the eSIM line. There is no extra charge. Roaming is already included in your plan.
My eSIM worked yesterday in Portugal but not today. What do I do?
Check that your plan is not expired or used up. If it is still valid, toggle airplane mode (10 seconds on, then off). If that does not help, force network selection to MEO then switch back to automatic.
Will my eSIM work in the Azores and Madeira?
Yes. The main islands have decent 4G. Levada trails in Madeira and smaller Azores islands may have weaker signal at altitude or inland.
