2FA / OTP forwarding for teams
The most common reason teams adopt SIMRelay: shared 2FA. A handful of business accounts — bank login, payment processor, hosting provider, ad platform — that an entire team needs occasional access to, but only one of you has the phone with the SIM. SIMRelay replaces "ping me for the code" with "the code is already in #ops-codes."
The problem you're trying to solve
You probably know it well. Someone owns the company AmEx login because they happened to sign up first. The recovery phone is their personal mobile. They go on vacation; nobody can log in. They leave the company; the phone goes too, and now you're talking to support to recover an account you've been paying for. The personal-phone-as-business-MFA pattern is brittle in three obvious ways and several non-obvious ones.
How SIMRelay fixes it
Sign up for SIMRelay, claim a hosted SIM, update your business accounts' 2FA phone to the SIMRelay number, configure forwarding to whichever channels your team uses (Slack channel, email distribution list, both). The verification code now arrives in the place your team already looks. Everyone authorized sees it; the personal-phone bottleneck is gone.
Why a real SIM matters here
Banks, payment processors, and brokers reject VoIP numbers for 2FA. The SIMRelay number passes their checks because it's a real SIM on a real carrier. You can use it where you currently use a personal phone — without the personal-phone fragility.
Who actually sees the code
Whoever you configure. The default is "the channel you pipe it to," but SIMRelay supports per-number locking: a teammate can claim exclusive read-access on a specific number for a window of time. Useful when you want to ensure that during a sensitive bank transaction, only the person doing the transaction sees the code, even if other teammates are in the integration channel.
Migration
The hardest part is updating each business account's 2FA number, which has to happen in each account's settings panel. Usually a one-evening task. After that, the personal-phone era is over.
