Hunting for the cheapest eSIM for your trip? The headline price is only half the story - currency conversion fees, throttled speeds and top-up costs can turn a cheap plan into an expensive one. Here is how to compare properly.
Current discounts are always listed on the SimplySim Deals Page.
1. Compare Price Per Gigabyte, Not Headline Price
A £5 plan with 1GB is worse value than a £11 plan with 10GB. Work out the per-GB cost for your destination before buying.
- Turkey: 1GB from £1.48
- Japan and Thailand: 1GB from £1.85
- Spain 10GB: £11.14 (about £1.11 per GB)
2. Watch Out for USD and EUR Checkouts
Many big eSIM brands charge UK customers in dollars or euros. Your bank then adds a foreign-transaction fee, typically around 3 percent, on top.
- SimplySim prices are in GBP
- What you see at checkout is what leaves your account
- Apple Pay, Google Pay, Klarna and major cards accepted
3. Use the Price Match Guarantee
Found the same plan cheaper elsewhere? SimplySim offers a price match guarantee on like-for-like plans, so you never need to shop around twice.
4. Students Save an Extra 10 Percent
With a university email address you get 10 percent off every order - see the student discount page. Few travel eSIM providers offer any student discount at all.
5. Regional Plans Beat Multiple Single-Country eSIMs
Visiting more than one country? One regional eSIM is cheaper than several local ones.
- Europe (35 areas): from £1.85, 10GB for £12.99
- Global plans covering 118+ countries for multi-continent trips
6. Compare Against Your UK Network's Roaming Rates
Daily roaming passes of £2 to £6 sound small but add up: two weeks away can cost £84 in passes alone. See the full breakdown on our network cost comparison against EE, Vodafone, Three and O2.
7. Who Benefits Most from a Cheap eSIM?
- Budget travellers and backpackers
- Students on gap years and study trips
- Short city breaks where a daily pass makes no sense
- Light data users who just need maps and messaging
Final Thoughts
The cheapest eSIM is the one with the lowest per-GB price in pounds, no hidden conversion fees and free top-ups when you need more. With plans from £1.48, GBP pricing and a price match guarantee, that search usually ends at the SimplySim Deals Page.
