sms.1mail.lt vs 5sim — A Real Comparison

5sim is one of the two Russian-based incumbents. Here's where they win, where we win, and who should pick which.

TL;DR: 5sim has bigger country coverage and a mature API. We have normal EU card payments (Stripe, Apple Pay, Revolut) and instant refunds to your bank. If you buy 100+ numbers/week with automation, use 5sim. If you buy 1-20 numbers and hate crypto flows, use us.

Where 5sim wins

Country coverage

190+ countries — including Vietnam, Kazakhstan, Bangladesh, Peru, and dozens more we don't stock. If you specifically need a number from outside our 25-country list, 5sim is one of very few providers that will have it.

Mature API

Well-documented REST API, generous rate limits, decent Python/JS SDKs in the community. If you're building a QA rig, growth tool, or research pipeline that needs to buy dozens of numbers per hour programmatically, 5sim's API is battle-tested. Ours is not shipped yet (Q4 2026 planned).

Cheaper on RUB-conversion months

5sim prices in RUB and converts to your currency at spot rate. When the ruble weakens, their EUR-equivalent prices dip below ours. This is unpredictable — some weeks they're 20% cheaper, some weeks 30% more expensive.

Where we win

Normal EU payment methods

Apple Pay, Google Pay, Revolut Pay, iDEAL, Bancontact, and any Mastercard/Visa. 5sim's card gateway routes through third parties that regularly reject European bank cards — Andrej (our founder) tried to top up 5sim with three different cards and had all three fail, which is literally why sms.1mail.lt exists. If you don't own crypto and don't want to buy it, we save you a 15-minute detour.

Guest checkout for one-offs

Need one number, right now, no account? Pay €0.40 with your card and go. 5sim requires signup + email confirmation + crypto deposit + wait for confirmations before you can buy. This is our biggest UX advantage for small buyers.

Real refunds to real bank accounts

Failed 5sim purchase = credit to your 5sim balance (spendable only there). Failed guest purchase on us = Stripe refund back to your card in 2-5 days. Wallet mode = instant refund but still to the wallet.

EU jurisdiction for compliance

If your employer's finance team requires EU-based suppliers (common for VAT reclaim, GDPR alignment, or Russian-sanctions compliance), 5sim is off the table. We're an EU company with proper VAT invoicing.

FAQ

Can I use both services?

Yes and we recommend it if you're doing anything at scale. Multi-sourcing means when one provider's UK pool gets burned by WhatsApp, you switch to the other in 30 seconds instead of waiting hours for stock to refresh.

Is 5sim safe to use?

Yes, they're a legitimate business operating since 2018 with ~2M active users. Delivery is reliable when their stock has fresh numbers. The main friction points are payment and jurisdiction, not safety.

Which is cheaper overall?

Depends on the week. Their RUB-conversion pricing dips below ours occasionally; our wallet-mode pricing beats their base card-payment pricing consistently. If you convert at spot rate on the day, we're usually cheaper for common EU-country services.

Do you have a referral program like 5sim?

Yes — €0.10 per friend who deposits, credited to your wallet automatically. 5sim's affiliate program pays ~5% of referred user spend in USDT.

What if I try you and it doesn't work?

Full refund. Guest checkout = card refund via Stripe (2-5 days). Wallet mode = instant credit. Either way, no lock-in.
