How to Sign Up for Telegram with a Private OTP Number (Without Exposing Your SIM)
Telegram prides itself on encryption—yet it still demands a phone number during sign-up. Using your everyday SIM links your real identity and invites SIM-swap fraud. Public SMS websites? Worse: anyone can read your code, and Telegram blocks their numbers after repeated abuse. This guide shows how a ChatOdyssey Phone Relay (free trial → $4.99/mo, unlimited email relay) gives you a private, reusable number trusted by Telegram.
Why Telegram Demands an OTP—and Why That’s a Problem
Telegram relies on phone-based identity to throttle spam bots and recover accounts quickly. The platform sends a one-time password (OTP) over SMS or voice to whatever number you provide. According to Privacy International research, this number becomes visible to contacts by default—creating a privacy paradox for whistle-blowers, journalists, and crypto traders who joined Telegram precisely to stay anonymous. Worse, a stolen or ported SIM lets attackers intercept new login codes and hijack your chats—an SMS weakness documented in Authgear’s OTP vulnerability white-paper.
The Mirage of Free “Receive-SMS Online” Websites
Services like Quackr publish hundreds of publicly shared SIMs so anyone can read incoming texts. Their own disclaimer spells it out: “Do not use for private accounts.” A deep-dive by Quackr’s security team lists three fatal flaws:
- 💀 Zero privacy — anyone can read or reuse your Telegram OTP.
- 🚫 Reliability — Telegram blocks many of these numbers after spam waves.
- 🔒 No persistence — if you log out, you lose access to that number forever, killing account recovery.
Security blog eSIM Plus confirms that Telegram actively blacklists abused VoIP blocks—leaving users locked out after initial sign-up (eSIM Plus guide).

Step-by-Step: Register Telegram via ChatOdyssey
- Visit ChatOdyssey Phone Relay and create a free account.
- Pick your private number (U.S. or international blocks coming soon).
- Open Telegram and enter that number.
- Watch your ChatOdyssey dashboard for the SMS code (or enable e-mail relay).

- Bonus: enable Telegram’s 2-step password and set “Who can see my phone number → Nobody”.
Why SMS Alone Isn’t Enough—Even with a Private Number
SMS relies on 1970s signaling protocols never designed for encryption. As Authgear’s security analysis notes, SS7 interceptions, SIM swaps, and malware on Android can all siphon OTPs. Using a masked line reduces SIM-swap surface area but you should still enable Telegram’s own in-app password or move to device-based 2FA for exchanges and wallets.
Who Benefits Most from a Reusable Telegram Number?
- Crypto founders & traders – keep trading group-chats off your personal SIM.
- Journalists & activists – reduce doxxing risk when reporting from conflict zones.
- Remote SaaS teams – onboard team Telegram bots under one stable relay line.
- Influencers – segment fan DMs from family calls.
- Frequent travelers – avoid roaming charges and SIM swaps when abroad.
