# Roaming in Portugal on a UK phone: the Algarve, Madeira and the Azores

Your UK phone most likely works in Portugal without a daily charge: ten of the 15 UK networks include it within a fair-use limit that starts at 5GB a month (checked on 24 October 2026). EE, Vodafone, Three, Sky and VOXI charge £2 to £2.75 a day or sell a pass. Our Portugal plan is £2.99 for 1 GB over 7 days, data only.

This site is not affiliated with any of the networks mentioned here; we sell eSIMs. [How we compare](https://esimworld.co.uk/how-we-compare/)

You may not need an eSIM. A golf week on the Algarve on an included plan needs nothing extra. An eSIM helps when your network charges by the day, your data cap is lower than your use, your network does not name the island you fly to, or you stay for the winter.

## Is roaming free in Portugal on my UK network?

Yes on ten networks, each within its own limit; no on five. O2 allows up to 25GB a month, Lebara up to 30GB, Lyca Mobile 12GB (35GB on its largest plans) and SMARTY 12GB (checked on 24 October 2026, [O2 EU roaming](https://www.o2.co.uk/eu-roaming)).

The low caps sit on three networks. giffgaff gives 5GB per plan and Asda Mobile 5GB a month. [Talkmobile](https://esimworld.co.uk/roaming/talkmobile/) gives 5GB a month if you joined or upgraded on or after 14 March 2023, and 15GB before.

iD Mobile lets you use your full UK allowance "until further notice", on a promotion; its usual limit is 30GB. Tesco Mobile says "There's no cap/usage limit", and BT includes Portugal in Roam Like Home. EU roaming included on many UK plans is each network's choice, not a law ([EU roaming after Brexit](https://esimworld.co.uk/roaming/europe/)).

The other five charge by plan and join date. A "day" is a day you use the phone, not a day away. The week column is our arithmetic from each network's published rate.

| Network | Charge in Portugal | 7 days of use | Pass for about a week |
|---|---|---|---|
| [EE](https://esimworld.co.uk/roaming/ee/) | £2.72 a day on plans launched from 7 July 2021 | £19.04 | Weekly EU Pass £16.50 |
| [Vodafone](https://esimworld.co.uk/roaming/vodafone/) | £2.75 a day on pay monthly from 11 August 2021, without Euro Roam or Global Roam | £19.25 | 8-day pass £16 |
| [Three](https://esimworld.co.uk/roaming/three/) | £2.75 a day on Lite and Lite+ from 18 December 2025; £2 if you joined from 1 October 2021 to 17 December 2025 | £19.25 at £2.75 | Go Roam in Europe, 7 days £12 |
| Sky Mobile | £2 a day on all plans except Diamond VIP | £14 | none; the £2 day is the pass |
| VOXI | no allowance abroad without a pass; 1 day £2.60 | £15 | 8-day pass £15 |
| Our Portugal plan | data only, no UK number, no calls or texts | 1 GB over 7 days: £2.99 | — |

A network pass keeps your own number, minutes and texts. Ours is a data-only eSIM that starts on first connection to a network in Portugal, so your UK SIM stays in for calls. [Roaming or eSIM](https://esimworld.co.uk/roaming-or-esim/) sets the two side by side.

## Madeira and the Azores: are the islands included?

Twelve of the 15 UK networks name both Madeira and the Azores in their Europe lists; Lebara, Lyca Mobile and giffgaff list Portugal without naming them (checked on 24 October 2026). Our Portugal plan covers both island groups.

How roaming in Portugal on [UK networks](https://esimworld.co.uk/roaming/) treats the islands comes down to each network's list. EE's price guide names "Azores" and "Madeira" among its daily-charge countries, so the £2.72 a day applies there as on the mainland ([EE price guide](https://ee.co.uk/content/dam/help/terms-and-conditions/price-plans/mobile/sim-only-price-plans/_ee-pay-monthly-standard-and-non-standard-price-guide-31st_March_2026_1.1.pdf)). Tesco's roaming calculator puts it in one row: "Portugal (inc. the Azores and Madeira)".

| Network | Madeira and the Azores | What it means for you |
|---|---|---|
| O2, iD Mobile, Tesco Mobile, BT, Talkmobile, Asda Mobile, SMARTY | named | included, with the same limits as the mainland |
| EE, Vodafone, Three, Sky, VOXI | named | the same terms as the mainland: daily charge, pass or included plan |
| Lebara, Lyca Mobile, giffgaff | Portugal listed, islands not named | ask your network before you fly |
| Our Portugal plan | named in the plan listing | the same plan and price as on the mainland |

If you fly between the mainland and the islands, a phone on board can join the aircraft's own network. That is charged far above normal roaming: EE's Aircraft Pass costs £16 per 10MB, which is £1.60 a MB (our sum, same EE price guide). Turn on aeroplane mode before take-off; a travel eSIM works on land networks, not in the air.

## Winter in the Algarve: when do the day limits bite?

Nine UK networks put a time rule on roaming in Portugal. [O2](https://esimworld.co.uk/roaming/o2/) charges £3.50 a GB after more than 63 days abroad in 4 months, and SMARTY may suspend service after 60 consecutive days (checked on 24 October 2026).

| Network | Time rule | After it |
|---|---|---|
| O2 | more than 63 days in 4 months | £3.50 a GB, 3.3p a minute, 1p a text |
| iD Mobile | 63 days or more in 4 months | 10p a MB, 3.2p a minute, 1p a text, with 14 days' notice |
| Vodafone | more than 62 days abroad, or more use abroad than in the UK over four months | £3.83 a GB, 3.3p a minute, 1p a text, after a text 14 days before |
| Talkmobile | 61 or more days in 120 | a surcharge of £7 a week, after a warning |
| SMARTY | 60 consecutive days abroad | the right to suspend all services, with an alert two weeks before |
| giffgaff | 63 days | roaming switched off, then you pay from credit |
| Tesco Mobile | more than 2 months in a rolling 4 | 0.35p a MB on data, after a text and two weeks to cut back |
| Three | two complete months in a rolling 12, only in Go Roam destinations | roaming may be suspended |
| Lebara | roaming over 120 days outweighs your UK use | a surcharge of 0.20p a MB |

Rules from [O2](https://www.o2.co.uk/termsandconditions/mobile/roamfairuse), [iD Mobile](https://www.idmobile.co.uk/help-and-support/eu-roaming/fair-usage-policy), [Vodafone](https://www.vodafone.co.uk/mobile/global-roaming), [Talkmobile](https://talkmobile.co.uk/acceptable-use-policy), [SMARTY](https://help.smarty.co.uk/en/articles/2090500-roaming-and-international), [giffgaff](https://help.giffgaff.com/en/articles/229458-everything-you-need-to-know-about-roaming-in-the-eu), [Tesco Mobile](https://www.tescomobile.com/content/dam/tesco-mobile/terms-and-conditions/general/home-from-home/fair-use-and-home-from-home-policies.pdf), [Three](https://www.three.co.uk/support/roaming-and-calling-abroad/roaming-abroad/go-roam) and [Lebara](https://www.lebara.co.uk/en/roaming/roaming-rate-finder.html).

A three-month winter on the Algarve crosses every line in that table. We hold no long-stay rule for EE, Sky, VOXI, Lyca Mobile, BT or Asda Mobile, so read their fair-use terms before a long stay.

A data-only eSIM does not move your UK number, so keep the UK SIM in for calls and texts ([keep your UK number](https://esimworld.co.uk/help/keep-your-uk-number/)). Our Portugal plans run up to 30 days from first connection, so a three-month stay takes three plans back to back.

## How we compared eSIMs for Portugal (checked on the date shown)

On 24 October 2026, four sellers' 5GB, 30-day Portugal plans ranged from £6.99 to £7.49 in pounds to a UK visitor, against £5.99 for ours. Each figure is a data-only plan with exactly the data and days shown.

We name no seller, and the table is not a ranking. Promotional prices are out, and so are prices a UK visitor sees in dollars.

| Basket | Sellers' range, 24 October 2026 | Our Portugal plan |
|---|---|---|
| 1GB, 7 days | £2.99 to £3.50 | £2.99 |
| 5GB, 30 days | £6.99 to £7.49 | £5.99 |
| 10GB, 30 days | £9.00 to £12.99 | £7.99 |

Coverage, network and speed differ by plan, so the figures are not like for like. Ours are GB and days plans, from 1 GB for 7 days to 20 GB for 30 days. On 4G/5G coverage we go by the plan listing: it names three Portuguese networks, MEO, NOS and Vodafone Portugal, each shown as 4G. We claim nothing for single resorts or golf courses. The listing sets no rule on hotspot and tethering, so we promise none.

## Portugal SIM card vs eSIM: which for Lisbon and the Algarve?

A Portugal eSIM from the UK goes on your phone before you fly; a Portuguese SIM card is bought there. We hold no Portuguese retailer prices, so the Portugal SIM card vs eSIM choice here is not about price.

Our Portugal plan can be installed up to 365 days ahead and covers Lisbon and Madeira alike. It needs an eSIM-compatible phone that is unlocked. Install before you travel, on Wi-Fi at home, as [the install guide](https://esimworld.co.uk/how-to-install-esim/) shows. For a trip that adds Spain or another country, see [the Europe guide](https://esimworld.co.uk/sim-card/europe/).

## Frequently asked questions

### Is roaming free in Portugal?

Yes on ten of the 15 UK networks, each within its own fair-use terms, starting at 5GB a month. EE, Vodafone, Three, Sky and VOXI charge £2 to £2.75 a day or sell a pass. Madeira and the Azores follow your network's own list.

### Does EU roaming cover Madeira and the Azores?

Often, but each network writes its own list; no law decides it. EE, O2, Vodafone, Three, Sky, VOXI, Tesco, iD, SMARTY, BT, Talkmobile and Asda name both islands. Lebara, Lyca Mobile and giffgaff list Portugal without naming them, so ask before you fly.
