You have crypto in your wallet and a trip coming up, but you still need mobile data when you land. One way to cover it is to buy an eSimity Credits gift card on G2A, redeem the code in eSimity and use the balance for a travel eSIM plan. When cryptocurrency payment is available for your G2A order, you can complete the gift-card purchase using that method instead of paying for the plan directly in the eSimity app.
There are two things worth knowing upfront: the code you buy is credit, not an installed eSIM, and the cryptocurrency and network available for payment depend on what G2A shows at checkout. The steps below cover both, so you can get from payment to a working travel data plan without confusing the two products.
Buy a travel eSIM with crypto: the short version
Open the eSimity Credits listing on G2A, choose a gift-card amount, and use the cryptocurrency payment method offered at checkout. After your payment is confirmed and the digital code is delivered, redeem it in your eSimity account. You can then choose a supported destination, pay for an eligible eSIM plan with your balance and install the eSIM on a compatible phone.
In order: crypto payment at G2A → eSimity gift-card code → account credit → travel eSIM plan. You do not scan the gift-card code to install a mobile network profile.
Choose the right eSimity Credits gift card
The G2A listing currently shows four face values: €10, €15, €25 and €50. These are credit amounts, not bundles with a fixed number of gigabytes. If you have already chosen your destination, check the price of the data plan first and then select a card amount that makes sense for your trip.
| G2A gift-card value | What you get | What to check |
|---|---|---|
| €10 | A digital code for €10 of eligible eSimity credit | Whether the plan you want fits your balance |
| €15 | A digital code for €15 of eligible eSimity credit | Your trip length and required data |
| €25 | A digital code for €25 of eligible eSimity credit | The final checkout total, including any fees |
| €50 | A digital code for €50 of eligible eSimity credit | Whether you expect to use the remaining credit later |
You can compare travel plan prices in the eSimity eSIM store before choosing a gift card. G2A is a marketplace, so always review the seller, activation region and final amount charged rather than assuming the face value and checkout total will always be identical.
Paying with crypto on G2A: what to check before sending funds
After adding the eSimity Credits card to your cart, go to checkout and select the cryptocurrency payment option available for that order. The exact coins, blockchain networks and payment provider can vary. Use the details on the payment screen in front of you, not instructions from an old video or a screenshot of someone else’s order.
- Coin and network: Match both. For example, USDT on TRON (TRC-20) and USDT on Ethereum (ERC-20) are not interchangeable transfer routes. This is a network-safety example, not a claim that either option is available on G2A for your order.
- Destination address: Copy the address or use the payment request provided by the official checkout. Do not use an address sent through a social media message or unofficial support account.
- Amount and timing: Check the required crypto amount, payment deadline, applicable network fee and any checkout conversion before you confirm the transfer.
- Confirmation: Keep the transaction reference and G2A order details until your digital code is delivered. Blockchain confirmation and code delivery are separate stages.
Crypto transfers are often irreversible. A wrong network or destination address can mean lost funds, and sending the right amount after a payment request expires may delay processing. If the payment method you expected is not offered at checkout, do not send crypto to an alternative address suggested outside the official payment flow.
Redeem the G2A code in your eSimity account
Once G2A has completed delivery, retrieve the digital code from your order. The eSimity Credits activation guide on G2A describes the redemption process: sign in to eSimity, find the credits or balance redemption area, enter the code, confirm and check the updated balance.
- Open the official eSimity app or website and sign in to the account where you want to keep your credit.
- Find the credits, balance or code-redemption section. Its exact label may differ between app versions.
- Enter the code exactly as delivered by G2A, confirm the redemption and check that the expected balance was added.
- Go to the eSIM store, choose your country or regional plan and check whether the available credit covers the purchase.
- Follow the plan installation instructions. Your device must support eSIM and be carrier-unlocked.
Keep the code private. It is not an eSIM QR code and does not install a mobile network profile by itself. The actual eSIM installation details are supplied after you select and purchase a data plan.
Gift-card credit and Pay As You Go are not the same thing
A gift card puts credit into your eSimity account. What you use that credit for comes next. You might choose a fixed-data package for a two-week holiday, or an eligible Pay As You Go option if you travel frequently and prefer to pay according to the destination rate.
| Option | How it works | When to consider it |
|---|---|---|
| Gift-card code | Adds account credit after redemption | When funding the account through G2A |
| Fixed-data eSIM plan | Provides a selected GB allowance for a specified validity period | When your dates and approximate data needs are known |
| Pay As You Go | Deducts eligible usage from the balance at destination rates | For repeated trips or changing data needs |
The eSimity Pay As You Go guide explains how a reusable wallet works. Before deciding, compare the actual PAYG rate for your destination with a fixed bundle; neither option is automatically cheaper for every traveler.
When do eSimity gift cards and account credits expire?
This is an important distinction. Under eSimity’s published Terms and Conditions, an unused voucher code is valid for three years from purchase or issue. After you redeem a valid code, ordinary account credits do not expire unless specific promotional terms say otherwise. Credits are non-transferable and are not redeemable for cash except where the terms or applicable law require it.
A travel data plan has a separate usage period. Paying for a seven-day plan with account credit does not make that plan valid forever. Also note that refunds for gift cards bought through a third-party seller need to be pursued with that seller under the applicable rules.
Troubleshooting a crypto payment or gift-card code
If you paid but cannot see your code, check the G2A order status and payment confirmation before attempting another purchase. If you received a code but it does not redeem, confirm that you are signed in to the correct eSimity account and that the code was copied without extra spaces. A code that has already been used or has expired will not redeem again.
For a payment or delivery problem, contact G2A or the seller with the order reference. For a code redemption or account-balance problem, contact eSimity Support with the relevant order details. Never publish the full redemption code, recovery phrase or wallet private key in a support ticket or public discussion.
Frequently asked questions
Can I buy an eSIM with Bitcoin, USDT or another cryptocurrency?
You can use a cryptocurrency payment method for the eSimity Credits purchase when that method is offered at G2A checkout. The available coins and networks must be checked on your actual order; this guide does not guarantee a particular cryptocurrency in every region.
Does the G2A gift card install an eSIM?
No. The G2A purchase delivers a code for eSimity account credit. You redeem the code, buy an eligible data plan and then install the eSIM using the plan’s separate activation instructions.
Can I use the credit for a destination other than Germany?
Yes. eSimity Credits are for eligible plans in the supported destination catalog, not just Germany. Check the specific country, regional coverage and plan conditions before paying.
Does my eSimity credit expire?
The unused gift-card code has a three-year validity period under eSimity’s terms. Once redeemed, ordinary account credit does not expire unless applicable promotional terms state otherwise. Fixed-duration data plans have their own validity rules.
What if the payment was confirmed but I have not received the code?
First inspect the order and delivery status in G2A. Keep your payment reference and contact G2A or the seller if delivery is incomplete. Do not pay a second time until you know what happened to the first order.
Can I buy a gift card if my phone does not support eSIM?
You can buy account credit, but using it for a travel eSIM requires a compatible, carrier-unlocked device. Check device compatibility before purchasing if the credit is intended for an upcoming trip.
From crypto to travel data
The useful part of this method is that you can fund an eSimity account through the G2A gift-card listing, then decide which supported destination plan you actually need. Check the checkout payment method carefully, redeem the digital code in your account and keep the separate eSIM installation details for your trip. The process is straightforward once the gift card and the mobile data plan are treated as two distinct steps.
