How to Fix Telegram Not Sending Code (Quick & Easy Solutions)

If Telegram isn’t sending you a verification code, you’re not alone. This is one of the most common issues users encounter when trying to log in, switch devices, or recover their accounts. The good news? Most of these problems can be solved easily—without contacting support. In this detailed guide, you’ll learn how to fix Telegram not sending code using simple, proven methods that work on both mobile and desktop.

Telegram relies on SMS, phone carriers, and internal security systems to deliver your login code. When any of these fail, the message may be delayed—or never arrive at all. Below, we break down every reason this happens and exactly what you can do to fix it.

Why Telegram Doesn’t Send the Code

Before diving into solutions, it helps to understand the most common causes:

• The phone number is entered incorrectly

• Your carrier is blocking automated messages

• You are using a banned or VoIP number

• SMS is delayed due to network congestion

• You requested too many codes in a short time

• Telegram temporarily restricted login attempts

• Poor mobile signal or airplane mode issues

• The Telegram app is outdated

Once you know the cause, how to fix Telegram not sending code becomes much easier.

How to Fix Telegram Not Sending Code (Mobile Solutions)

Below are the quickest and most effective solutions for smartphone users:

1. Check Your Phone Number Format

Make sure you:

• Select the correct country code

• Enter your number without extra symbols or spaces

• Avoid using a secondary or VoIP number

Incorrect formatting is the most common reason for failed SMS delivery.

2. Restart Your Phone

A simple restart can reset your network modules and fix temporary SMS delays.

• Turn off your device

• Wait 10–15 seconds

• Turn it back on and retry

This alone resolves how to fix Telegram not sending code for many users.

3. Disable Airplane Mode and Check Network Signal

Ensure that Airplane Mode is off and your device has stable mobile reception. Poor signal = blocked SMS.

4. Request a Call Instead of SMS

Telegram sometimes offers the option “Didn’t get the code? Request a call.”

If SMS isn’t working, Telegram will call you and read the code out loud.

5. Clear the Telegram App Cache (Android)

If the app is glitching:

1. Go to Settings → Apps → Telegram

2. Tap Storage

3. Select Clear Cache

This resets temporary files without deleting messages or chats.

6. Update Telegram to the Latest Version

An outdated app may block authentication requests.
Visit the App Store or Google Play Store and update Telegram to the latest release.

7. Check If Your Number Is Banned or VOIP

Telegram has strict filters. Numbers from some VOIP services (TextNow, Google Voice, etc.) often fail to receive codes.

Use an official mobile carrier number instead.

How to Fix Telegram Not Sending Code (Desktop Solutions)

If you're logging in from Telegram Desktop or Web:

1. Confirm Your Number Before Trying Again

Make sure the number you typed matches the one linked to your Telegram account.

2. Check PC Network Connection

A weak or unstable Wi-Fi connection may block authentication requests.

3. Use Telegram Web Instead of Desktop

Try logging in at: web.telegram.org

Sometimes the desktop client experiences temporary delays that don’t affect the web version.

4. Disable VPN or Proxy Services

VPNs can interfere with Telegram’s login system, causing delays in receiving codes.
Turn off VPN and try again.

Other Common Fixes That Work for Most Users

1. Wait 5–10 Minutes

If you requested multiple codes too quickly, Telegram may throttle delivery.
Waiting a few minutes before retrying often solves the issue.

2. Check SMS Blocking Apps

If you use a spam filter or call blocker app, it may be blocking the Telegram SMS.

Whitelist Telegram or disable the app temporarily.

3. Remove SIM, Reinsert, and Retry

This refreshes your carrier connection and can restore SMS functionality.

4. Contact Your Mobile Carrier

If your operator is blocking automated SMS, ask them to unblock short-code messages.

When Telegram Will NOT Send a Code

Telegram may refuse to send a code when:

• Too many failed login attempts occurred

• Suspicious activity was detected

• The number was recently used on another device

• Account protection mode is active

When this happens, you may need to wait several hours before retrying.

Does This Affect Your Account?

No. Issues related to how to fix Telegram not sending code do not impact your Telegram account, chats, or saved media. This is only a verification problem—not an account suspension or ban.

Extra Tips to Avoid Code Problems in the Future

• Keep your Telegram app updated

• Avoid switching devices too frequently

• Make sure your SIM is active and not expired

• Turn off VPN when logging in

• Save your recovery email in the Two-Step Verification section

These simple habits ensure a smoother login process.
