eSIM Promo Codes for United Kingdom

Depending on how much data your trip needs and how long you want it to last, that single redemption is worth roughly $0.60–$36.

Airalo's checkout has a promo box: drop ESIMDB15 into it before paying and 15% comes off your UK eSIM. One thing to watch is that the discount does not apply to Airmoney, PayPal, Apple Pay or Google Pay, so settle up with a card instead.

On Airalo's United Kingdom plans the code is worth roughly $0.60–$28, depending on the bundle you choose.

Shopping for a UK eSIM with Ubigi? Type ESIMDB10 into the promo field at checkout, on the site or in the Ubigi app, and 10% comes off before you pay. It is a one-per-account code, and it does not apply to Ubigi's monthly subscription plans.

Across the prepaid UK options that adds up to a saving of around $0.20–$39, depending on the plan you pick.

New to Nomad? Your first UK plan can come in $3 cheaper. Add the eSIM to your cart, enter ESIMDB3 where Nomad asks for a promo code, and the reduction is applied before payment. It covers selected plans only, and discounted orders are not refundable.

That means $3 off your opening Nomad purchase, taken straight from the checkout total rather than refunded later.

On the UK plans it covers, expect the code to trim around $0.40–$1.90 off your total.

Eskimo eSIM asks for the promo code when you sign up rather than at the very end of checkout, so enter ESIMDB while creating your account. Doing so knocks $7 off, and the code can be redeemed once per account.

For a UK trip that is a straight $7 off what you would otherwise pay Eskimo, applied to the plan you choose.

Yesim handles this one slightly differently. Instead of a checkout field, open Account, choose Redeem Code and enter ESIMDB20 on the web or in the app. That applies 20% to your data plan, and the offer is limited to a first purchase.

A first order with UPeSIM costs 10% less if you enter ESIMDB10 in the promo field before payment. The code is reserved for first-time customers and will not combine with other UPeSIM discounts, so apply it while you are still on the checkout page.

Depending on the UK plan you settle on, that is about $0.23–$12 saved on the order.

Billion Connect takes 10% off a UK data plan once you have entered ESIMDB10 at checkout. Each account gets one use, and the code will not sit alongside other Billion Connect promotions, so pick your plan first and apply it just before paying.

BNESIM customers can claim 15% off by entering ESIMDB15 in the promo field during checkout, before the payment step. The code is good for one use per account, so it is worth saving for the UK plan that matches your trip length.
