About us
A small team running a simple product: travel eSIMs that just work.
megaesim.us is operated by MegaESIM.us LLC, a US-registered limited liability company. We sell prepaid travel eSIM data plans and deliver them to your inbox as QR codes the same day you order. That's the whole thing.

How we operate
Four rules we stick to.
Small team, real people
We're a small operation — not a mega-retailer. Your email lands with an actual human who can look up your order and reply the same day.
No subscription games
You buy the plan you need and that's it. Nothing auto-renews, nothing gets quietly upgraded, and top-ups are one-time.
Payments we don't touch
Card data goes straight to Stripe. We only see a payment confirmation and the email you used at checkout.
Coverage that actually works
We sell plans on top of mobile networks we've tested on real devices — not whatever drop-shipped SKU was cheapest this week.
Who we rely on
Infrastructure & partners
We don't try to build everything in-house. The pieces we trust to third parties are picked for reputation and compliance, not cost.
| Partner | Role | Why it matters |
|---|---|---|
| Stripe | Card processing | PCI-DSS Level 1. Your card never touches our servers. |
| Brevo (Sendinblue) | Transactional email | Delivery for your QR code, receipts and order updates. |
| Cloudflare | DNS & email routing | Domain, TLS termination, email forwarding. |
| Tier-1 mobile carriers | Coverage | Partnered GSM/LTE/5G networks across the EU, UK and Switzerland. |
Still have a question before you buy?
We'd rather answer it now than have you refund later.
