Enter the code at checkout, in the Yesim app or on the website, and press "Apply". The discount comes off before you pay. It covers your first order, so choose the plan for your next trip and use the code on that. Open Yesim through the link above, pick a destination, and the 15% is one step away.

Yesim in brief

Yesim is an eSIM app that gives you mobile data in 170+ countries. Install a plan on your phone and you connect to local data abroad. There is no roaming bill and no tiny SIM card to swap at the airport.

Holiday makers and business travellers buy it. The best-known plans are Pay & Fly, a pay-as-you-go option, plus the Unlim Day Pass and the Global Plus Package. Yesim also sells country plans for places such as Thailand, the United States and Japan.

Yesim UK prices with the discount

Yesim lists its prices in pounds. These are the "from" prices on its homepage on 16 October 2026, before the code. The 15% comes off at checkout on your first purchase.

Plan	Price before the code	Covers
Pay & Fly pay-as-you-go	from £0.83 per GB	170+ countries
Unlim Day Pass	from £2.23 per day	83 countries
Global Plus Package	from £2.45 per GB	146 countries
Thailand eSIM	from £1.26 per day	Thailand
United States eSIM	from £1.35 per day	United States

United Kingdom eSIM	from £1.71 per day	United Kingdom
Turkey eSIM	from £1.71 per day	Turkey
Egypt eSIM	from £2.07 per day	Egypt

The bigger your first order, the more pounds the 15% keeps in your wallet. A longer trip or a larger data plan is where HONESTCODES does the most work.

What a Yesim eSIM gives you

• Data in 170+ countries. Pay & Fly is pay-as-you-go from £0.83 per GB, so you buy data by the gigabyte as you travel.
• Day passes. The Unlim Day Pass starts at £2.23 per day and covers 83 countries, a neat fit for short breaks.
• Wider regional cover. The Global Plus Package starts at £2.45 per GB and reaches 146 countries.
• Country plans. Thailand starts at £1.26 per day, the United States at £1.35 and Japan at £1.65. Even the UK plan starts at £1.71 per day.
• Fast set-up. After payment, Yesim sends a QR code. Scan it and the eSIM installs in a few taps.
• No roaming charges. Your phone uses a local data plan abroad, so your home network's roaming rates never come into play.
• App or website. Buy in whichever suits you. The code is accepted in both.

Who it suits

• Holiday makers. Flying somewhere sunny and tired of roaming bills? Take the 15% off your first plan and land with data already installed.
• Business travellers. A day pass or a regional package keeps your phone online on arrival. Yesim sends the eSIM by QR code, so you can set it up before you leave.
• Christmas and New Year flyers. Nothing is posted. The eSIM arrives digitally after payment, so there is no last order date to worry about.
• First-time eSIM buyers. The code only works on a first purchase, which makes it a good reason to try an eSIM on your next trip.
