Frequently Asked Questions
Anything not answered here: contact us.
Do I need to provide ID or personal details?
No ID, no account. Email is optional and only used to send your order link.
What payment methods do you accept?
Bitcoin, on-chain and Lightning, and Monero. Other coins work too: Trocador at checkout swaps them automatically.
Do I need an account?
No. Every order lives at its own private link. Bookmark it: that link is the only way back to your eSIM.
Does the data eSIM come with a phone number?
No. It is data-only: maps, browsing, apps. It will not receive calls, SMS, OTP codes.
Can I use it as a hotspot or tether to my laptop?
Yes. Tethering and personal hotspot work normally on our data eSIMs.
How fast is the internet speed?
eSIMs connect to local 4G/5G networks. Speed depends on the network and your plan; any cap is shown in the plan specs before you buy.
When should I install it, and what is the “Activate by” date?
Install any time before you travel; validity only starts counting from first use at your destination. The “Activate by” date on your eSIM is the install deadline. Install before then or the eSIM is lost.
Can I top up my data later?
Yes. Open your eSIM page and buy another bundle before it expires.
Does unused data roll over?
No. When the data or the validity period runs out, the eSIM stops.
What do I get with the eSIM with Number?
A real Estonian +372 mobile number: voice, SMS and data billed from a prepaid EUR balance.
Do you offer numbers from other countries?
Estonian +372 is the only number we sell right now. It roams, so you can use it abroad wherever it has coverage.
Can I receive verification texts (OTP) from Telegram, WhatsApp or my bank?
Yes, in most cases. It is a real mobile number, so it works with most services that send verification codes. We cannot guarantee any individual service: platforms apply their own anti-abuse checks against a broad range of signals, and message delivery rests with the sender. A declined registration or an undelivered code is therefore not grounds for a refund. If you need the number for a specific service, confirm it works before relying on it.
Does the number work abroad?
Yes, it roams. You pay the rate listed for the country you are in, not an Estonian rate. Per-country data, SMS and voice rates are at /rates.
Does the number expire?
It stays valid 180 days from activation, and each recharge extends it. Let it lapse and the number is lost. Email support to ask about restoring it.
Can I move it to another device?
Yes, but delete it from the old device first. Use your phone’s eSIM settings, or the app you installed it with, and allow the deletion notification when prompted. Do not delete it from the SIM Toolkit. Wait about 10 minutes, then scan your original QR code on the new device. If the old device is gone or the QR still fails, contact us for a replacement QR: it is paid, and it cancels the old one.
My phone says the eSIM is already in use, or rejects the QR code.
The profile is usually still installed on another device, or the QR has already been used. An error mentioning “MatchingID” means the same thing. Delete the eSIM from the old device using your phone’s eSIM settings, wait about 10 minutes, then scan again. If the old device is gone or cannot send the deletion, contact us for a paid replacement QR.
Is my phone compatible?
It needs eSIM support and it must be carrier-unlocked. Open Settings and look for “Add eSIM” or “SIM Manager”. Phones bought on a carrier contract are often locked, so check before you buy.
How and when do I get my eSIM after paying?
You get a private order link with the QR code and activation details. The eSIM with Number is ready immediately; a data eSIM is usually ready within minutes of your payment confirming, and the link updates itself.
I lost my order link. Can you find my eSIM?
Email support@simsup.com from the address you gave at checkout. If you ordered without an email there is nothing tying the order to you, and we may not be able to recover it.
What if it does not work? Can I get a refund?
Email support@simsup.com first. Most problems are a quick reinstall or an APN fix. Not installed yet? Refund or replacement within 7 days. Faulty on our side or the provider’s? We replace or refund, paid in Monero. Once installed it is treated as used. Full terms at /terms.
