How do I install my eSIM?+
After your crypto payment confirms on-chain, we provision your eSIM automatically. The QR is usually ready within a few minutes on the success page; we also email it, or you can retrieve it with your retrieval code. On iPhone: Settings → Cellular → Add eSIM → Use QR Code. On Android: Settings → Network & internet → SIMs → Add eSIM. Install while you're on Wi-Fi, then activate when you arrive at your destination.
I paid but haven't received my eSIM yet.+
Provisioning usually takes just a few minutes. You can check your order status any time on the order lookup page using your retrieval code, or your email and order number. If it has been more than about 15 minutes, or the status shows failed, contact us with your order number and we'll resend the QR or retry provisioning.
Why can a crypto payment arrive short when I sent the quoted amount?+
Some exchanges deduct their withdrawal fee from the amount you enter instead of charging it separately. The receiving address then gets less than the invoice expects. Check the exchange's fee preview and add that fee so the exact quoted crypto amount reaches the payment address.
What happens if my payment is underpaid?+
We record the funds, pause automatic eSIM delivery and show the received amount, expected amount and shortfall on the order status page. Do not send the full amount again. Contact support with your order number so we can review whether to resolve the difference or arrange a refund. Never send funds to an address supplied in an unsolicited message.
Which cryptocurrency is best for a small order?+
Use a currency shown as available for your exact order total. Litecoin and BNB Smart Chain are usually inexpensive for small payments; supported Solana options can also be economical. Bitcoin mainnet and USDT on TRC-20 can have higher minimums or withdrawal fees, so the checkout disables them when the current amount cannot safely cover the provider minimum.
Which phones support eSIM?+
Most flagship phones released since 2018 support eSIM — iPhone XR/XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy S, Note and Fold models. Your phone must also be carrier-unlocked. If you're unsure, search your exact model plus 'eSIM support', or look for an 'Add eSIM' option in your phone's settings before you buy.
How do I check my remaining data or expiry date?+
Once your eSIM is delivered, the order lookup page shows your data usage and validity window. Open it, enter your retrieval code (or email and order number), and your remaining data and expiry are listed alongside your eSIM details.
Can I get a refund?+
All sales are final once an eSIM profile has been delivered. Unfulfilled or failed orders are refundable in the original crypto to the sending address upon request.
How anonymous is my purchase, really?+
We ask for no account, no ID and no card — you pay in crypto and receive your eSIM by email or an anonymous retrieval code, so the purchase itself reveals as little as you want. Be clear-eyed about the limits, though: no eSIM hides the network layer (your device's IMEI and the towers it connects to). We call this 'anonymous purchase', not 'anonymous connection'. Our guide 'How anonymous is your eSIM, really?' explains it in full.
My QR code won't scan, or activation failed.+
Reinstall while connected to Wi-Fi, and don't delete the eSIM profile after installing — most profiles can only be installed once. If scanning fails, choose 'Enter Details Manually' and paste the SM-DP+ address and Matching ID from your delivery email. Still stuck? Contact us with your order number (never your full retrieval code) and we'll help.
Do you cover my destination?+
We offer local, regional and global plans across 190+ countries. Browse the full catalog to find a plan for your destination — you can search by country and compare data, validity and price.
How do I contact support?+
Open our anonymous support chat at /support for immediate automated guidance and verified order-status help, with no account or email required. Complex requests are queued for support and may take longer. You can also email [email protected] or message @zeroxesim on Telegram. Never share your full retrieval code in chat.
