Travel eSIM prices before Black Friday at a glance
Black Friday 2026 falls on Friday 27 November, with Cyber Monday on 30 November. None of the three shops showed a Black Friday offer on its page on 6 November 2026, so treat these listed prices as the ones to beat. The three buttons on this page open Mozillion’s Greece page, Breeze’s Greece page and WorldSIM’s International eSIM Pro page.
Breeze Greece: 1GB for 7 days or 2GB for 15 days, both at £4, as listed on 6 November 2026 (under See more plans on the Greece product page).
Mozillion Greece: 3GB for 30 days at £4.50 on the Greece destination page.
WorldSIM International eSIM Pro: £25 for £15 of airtime, including a £10 eSIM cost, with 30-day airtime validity (larger options on the same page cost £35, £50 and £100).
If you only need data for maps, WhatsApp and boarding passes, a prepaid travel eSIM lets you fix the cost before you fly. Your home SIM can stay in for calls and texts while the eSIM carries mobile data.
Why a travel eSIM beats surprise roaming this winter
Christmas and New Year trips to Greece, the wider Med, the USA, Turkey, the Gulf and long-haul Asia are when UK roaming add-ons get expensive. Your network’s roaming add-ons are useful when you want one bill, so compare their daily price with a prepaid eSIM before you travel. A travel eSIM is bought before you fly, installed over Wi-Fi, and capped at the plan price you already paid.
Modern iPhones and most recent Android phones support eSIM. You keep your UK number on the physical SIM or a second eSIM line, turn data roaming off on the home line, and set the travel eSIM as the data line. That is the setup that avoids a bill shock when your hotel Wi-Fi drops out on arrival.
Black Friday is a useful prompt to buy early if your dates are fixed. Plans are prepaid and start when you activate them, so you are not locked into a 24-month mobile contract. Match the validity window to your return flight: Breeze’s Greece 1GB option is a 7-day plan, while Mozillion’s Greece 3GB option runs for 30 days.
Travel eSIM deals compared side by side
Compare destination, data, validity and currency on the shop page. The three rows below match the three purchase buttons on this page.
Plan | Data / validity | Price as listed on 6 November 2026 | Best for | Catch |
|---|---|---|---|---|
Breeze Greece | 1GB / 7 days or 2GB / 15 days | £4 | Short Greece trip | Light data; pick 2GB for the same price |
Mozillion Greece | 3GB / 30 days | £4.50 | Longer Greece stay on a budget | Still data-only |
WorldSIM International eSIM Pro | £15 airtime, 30-day validity, up to 10GB by country | £25 (includes £10 eSIM cost) | Calls, texts and reusable credit | Higher entry price; allowances vary by country |
For a single-country Greece holiday in pounds, Mozillion and Breeze make budgeting simple. WorldSIM suits travellers who want reusable international airtime rather than a one-shot country pass.
Breeze Greece eSIM, 1GB for 7 days, £4
- £4 one-off for 1GB over 7 days on Breeze’s Greece travel eSIM, as listed on 6 November 2026
- Shown under See more plans on Breeze’s Greece product page; larger Greece plans sit above it
- Main limitation: 1GB over 7 days is light data; the same page listed 2GB for 15 days at the same £4
Mozillion Travel: Greece 3GB for 30 days at £4.50
Mozillion’s Greece destination page listed a 3GB plan for 30 days at £4.50 on 6 November 2026. The View this deal button opens that Greece page, where you choose 3GB – 30 days. The same page also lists 10GB for 7 days at £8.50 and 10GB for 30 days at £10.
Pick Mozillion Greece when you want a clear sterling price and a month of validity on light data. The 3GB allowance suits maps, messaging and boarding passes more than heavy hotspot streaming.
Breeze eSIM: Greece 1GB for 7 days at £4
Breeze’s Greece product page listed a 1GB plan for 7 days at £4 on 6 November 2026, under See more plans. The same page listed 2GB for 15 days at the same £4 and 3GB for 30 days at £5. The Choose this plan button opens that Greece page, where you pick the plan you want.
Pick Breeze Greece for a short Aegean trip. At £4, the 2GB plan gives twice the data and a longer window than the 1GB plan, so choose it unless you only need a few days of maps and messages.
WorldSIM: International eSIM Pro from £25
WorldSIM’s International eSIM Pro page sells prepaid airtime with data, calls and SMS across a large country list, plus a UK number. As listed on 6 November 2026, the cheapest option costs £25: £15 of airtime plus a £10 eSIM cost, with 30-day airtime validity and up to 10GB of data, 180 minutes and 45 texts depending on the country. Larger options cost £35, £50 and £100.
Choose WorldSIM when you want one eSIM you can top up across trips, rather than a single fixed-GB holiday pass. For a simple Greece data bucket, Mozillion or Breeze usually compare more cleanly.
Which travel eSIM suits your trip?
Short Greece break
Breeze’s Greece plans at £4 (1GB for 7 days or 2GB for 15 days) are the lowest prices on this page. If you need a month of validity and a little more data, Mozillion’s Greece 3GB for 30 days at £4.50 is only 50p more.
Calls and a reusable number
WorldSIM’s International eSIM Pro £15 airtime is built around credit, incoming calls and a UK number, not a single fixed holiday data bucket. Use it when you need voice options as well as data across several trips.
Heavier data or a longer stay
Both Greece purchase plans are light-data options. If you will hotspot a laptop or stream every evening, open the merchant page from the matching button and step up to a larger Greece plan on that same destination page before you pay.
How to install a travel eSIM before you fly
Buy on home Wi-Fi. Check your phone is unlocked and eSIM-compatible. Install the plan from the QR code or carrier app the shop emails you. Leave the plan’s data line off before you land if the instructions say the validity clock starts on first use. On arrival, enable the travel eSIM for mobile data, keep your UK SIM for calls and SMS if you need them, and turn data roaming off on the UK line.
Test WhatsApp and maps before you leave the airport Wi-Fi bubble. If the plan is data-only, bank texts still land on your UK number. That is usually what you want.
