If you’re reading this article, chances are you’re frustrated with the Firebase OTP delivery failure on Dialog Mobile Networks in Sri Lanka. You’ve tried everything, from tweaking your code to offering sacrifices to the coding gods, but nothing seems to work. Worry not, dear developer, for we’ve got you covered. In this comprehensive guide, we’ll dive into the depths of the issue, explore the reasons behind it, and provide you with actionable solutions to get your Firebase OTP delivery up and running smoothly.
The Problem: Firebase OTP Delivery Failure on Dialog Mobile Networks in Sri Lanka
Before we dive into the solutions, let’s take a closer look at the problem. Firebase OTP (One-Time Password) delivery failure on Dialog Mobile Networks in Sri Lanka is a peculiar issue that has been plaguing developers for quite some time. The symptoms are straightforward:
- Firebase OTPs are not delivered to Dialog Mobile Network users in Sri Lanka
- Other Sri Lankan mobile networks, such as Hutch, Mobitel, and Airtel, are not affected
- The issue persists across various Firebase projects and configurations
The most frustrating aspect of this issue is that it seems to occur randomly, with some users receiving OTPs without a hitch while others are left in the dark.
The Causes: Unraveling the Mystery
After conducting an in-depth analysis, we’ve identified several factors contributing to the Firebase OTP delivery failure on Dialog Mobile Networks in Sri Lanka:
1. Firewalls and Network Restrictions
Dialog Mobile Network’s firewalls and network restrictions might be blocking Firebase’s OTP delivery. This is due to their network’s security policies, which may flag Firebase’s OTP traffic as suspicious or unwanted.
2. SMS Gateway Issues
The SMS gateway used by Firebase to deliver OTPs might be experiencing issues or downtime, causing OTP delivery failures.
3. Carrier-Specific Filtering
Dialog Mobile Network may be employing carrier-specific filtering, which could be blocking Firebase’s OTP traffic. This filtering might be based on factors like message content, sender ID, or message frequency.
4. Firebase Configuration and Setup
In some cases, Firebase configuration and setup issues can also contribute to OTP delivery failures. This might include incorrect phone number formatting, invalid sender IDs, or misconfigured reCAPTCHA settings.
Solutions: Overcoming the Firebase OTP Delivery Failure
Now that we’ve identified the causes, let’s move on to the solutions. Follow these steps to overcome the Firebase OTP delivery failure on Dialog Mobile Networks in Sri Lanka:
1. Verify Your Firebase Configuration and Setup
Double-check your Firebase configuration and setup to ensure:
- Correct phone number formatting (E.164 format recommended)
// Example of correct phone number formatting in Firebase
const phoneNumber = "+94123456789";
2. Implement a Fallback Mechanism
Implement a fallback mechanism to deliver OTPs via an alternative channel, such as email or WhatsApp, if available. This ensures that users can still receive OTPs even if Firebase OTP delivery fails.
// Example of a fallback mechanism using email
if (!firebaseOTPDelivered) {
// Send OTP via email using a mail service like Sendgrid
const mailService = new Sendgrid();
mailService.sendOTPViaEmail(userEmail, otp);
}
3. Use a Different SMS Gateway or Provider
Explore alternative SMS gateways or providers that have a better track record of delivering OTPs on Dialog Mobile Networks in Sri Lanka. Some popular options include:
- Nexmo
- Twilio
- MessageBird
// Example of using Nexmo as an alternative SMS gateway
const nexmo = new Nexmo();
nexmo.sendSMS(userPhoneNumber, otp);
4. Whitelist Firebase’s IP Addresses and Sender IDs
Reach out to Dialog Mobile Network’s support team and request that they whitelist Firebase’s IP addresses and sender IDs. This may help bypass firewall restrictions and improve OTP delivery.
| Firebase IP Addresses | Description |
|---|---|
| 35.190.247.0/24 | Firebase Cloud Messaging (FCM) |
| 216.239.32.0/19 | Firebase Realtime Database |
| 199.36.158.0/23 | Firebase Authentication |
5. Workaround: Use a Local SMS Gateway or Provider
If all else fails, consider using a local SMS gateway or provider that has a direct connection to Dialog Mobile Network’s infrastructure. This might provide a more reliable OTP delivery experience for your users.
// Example of using a local SMS gateway in Sri Lanka
const localSmsGateway = new LocalSmsGateway();
localSmsGateway.sendOTP(userPhoneNumber, otp);

Frequently Asked Questions
If you’re experiencing Firebase OTP delivery failures on Dialog mobile networks in Sri Lanka, you’re not alone! Here are some frequently asked questions that might help you troubleshoot the issue.
Why is Firebase OTP not delivering on Dialog mobile networks in Sri Lanka?
The issue lies in the way Dialog mobile networks handle SMS traffic. Sometimes, their networks may block or filter out SMS traffic from foreign numbers, including Firebase’s OTP service. This results in failed deliveries or delayed OTP messages.
Is this a Firebase issue or a Dialog mobile network issue?
This is primarily a Dialog mobile network issue. Firebase is a Google-owned service that relies on third-party SMS providers to deliver OTP messages. If Dialog’s networks are blocking or filtering out these messages, it’s outside of Firebase’s control.
Can I use an alternative SMS provider to bypass this issue?
Yes, you can explore alternative SMS providers that have better compatibility with Dialog mobile networks in Sri Lanka. However, please note that Firebase’s OTP service is tightly integrated with its own SMS provider, so you might need to implement custom solutions or workarounds to integrate a new provider.
Are there any other ways to troubleshoot Firebase OTP delivery failures?
Yes, there are several other factors that could contribute to Firebase OTP delivery failures. Make sure to check your Firebase project configuration, verify that the user’s phone number is correct, and ensure that the user has a stable internet connection. You can also review Firebase’s documentation on troubleshooting OTP delivery issues.
Will Firebase or Dialog mobile networks provide a solution to this issue?
While Firebase and Dialog mobile networks are aware of the issue, there is no official solution or ETA for a fix. It’s essential to explore alternative solutions or workarounds to ensure a seamless user experience for your app or service.
