About SIMRelay

SIMRelay was built because the existing way to share SMS verification codes across a team was broken in every direction we looked at it.

What we believe about phone-based identity

Phone numbers became a quiet, accidental identity layer for the internet. Every signup, every account recovery, every step-up authentication hands off to SMS at some point. That's awkward — phones are personal — but the alternatives haven't materialized fast enough, and SMS is going to be load-bearing identity infrastructure for at least another decade.

If that's where the world is, then the tools have to catch up. A business account shouldn't depend on one employee's personal phone. An AI agent shouldn't be stuck when a service asks for SMS verification. Those are infrastructure problems, and SIMRelay is one attempt at solving them.

Who we are

SIMRelay is operated by SIMRelay GmbH, headquartered in Germany. We're a small team focused on getting a few things right rather than building every feature anyone has ever asked for. If you talk to us, you'll likely talk to one of the people who builds the product.

How we work

• EU-hosted infrastructure. GDPR-aligned by default.
• Honest changelog. We tell you when things break.
• No surprise pricing. The pricing page is the pricing.
• Real humans answer support. We don't pretend to be 24/7 if we're not.

What we don't do

We don't enable phone-verification abuse. We don't sell SMS marketing volume. We don't get into voice or RCS or A2P. Those are good businesses run by other people; SIMRelay does one thing — hosted SIMs forwarded to teams and agents — and tries to do it well.
