Currently, only some calls to Iranian landlines are going through. Calls to Iranian mobile numbers are not connecting from anywhere in the world. We will update this information as soon as we detect successful connections.
Mytello works during Iran’s internet shutdowns because it routes calls through landlines (PSTN), not VoIP. WhatsApp and Telegram rely on internet access, which is often blocked. Mytello lets you call Iranian numbers, even if the person has no WiFi, app, or mobile data.
When WhatsApp, Telegram, and Signal go dark in Iran, Mytello still connects. That’s not by accident, it’s by design. Most messaging and voice apps rely on internet-based VoIP, which the Iranian government can throttle, block, or shut down completely during political unrest.
That’s exactly what’s happening in mid-2025: government-triggered outages have rendered VPNs unreliable and apps unusable. If you’re trying to reach someone in Iran during these blackouts, your call likely won’t go through, unless you’re using a tool that doesn’t depend on the internet.
Mytello uses a hybrid system that routes your call through the global phone network, not blocked IP channels. You use your app; they get a normal phone call, no internet, no app install, no data plan required on their side.
In this guide, we’ll explain:
- Why VoIP apps fail during Iran’s blackouts
- How Mytello’s call routing bypasses government firewalls
- Why landlines offer better stability than mobile numbers
- How to use Mytello to call Iran right now, without roaming, SIM swaps, or VPNs
If you’ve tried everything and nothing’s working, this article will show you the workaround that does. Let’s get into the why, and more importantly, the how.
Internet Shutdowns in Iran: Why Messaging Apps Fail
Iran has a history of restricting online services during protests or political unrest. In such periods, VoIP services like WhatsApp, Telegram, Signal, and even Zoom become unusable, as they depend on uninterrupted broadband or 4G networks. These platforms use peer-to-peer or packet-switched VoIP channels, which are often blocked by DPI (Deep Packet Inspection) technology or nationwide IP filtering. According to our updated Iran calling guide, even VPNs fail when DPI targets popular protocols or when connectivity is reduced below 2G speeds.
What Makes Mytello Different from WhatsApp & Telegram?
Unlike WhatsApp or Telegram, Mytello connects your calls via the global PSTN (Public Switched Telephone Network), which means the app itself only needs to establish a secure control session; the actual voice traffic is routed via traditional landlines. This is what allows Mytello to work even when the internet in Iran is blocked.
Additionally, the Mytello app works on both iOS and Android:
Unlike free VoIP apps, Mytello does not require the receiver to be online or have the app installed. This gives it a key advantage in countries where data access is limited.
Can You Still Call Landlines in Iran? Yes, Here’s Why That Matters
Landlines in Iran remain the most reliable option during digital blackouts, especially when mobile networks experience congestion. Mytello users can dial both Iranian landlines and mobile numbers directly from the app, even if the receiver has no internet access.
According to Mytello’s Iran-specific rates, calls to Iran landlines are often cheaper and more stable than calls to mobile phones. During times of heavy network traffic, landline infrastructure offers higher capacity and less latency, making it a better option for critical conversations.
Why VoIP Over GSM Works Better in Crises
VoIP apps like WhatsApp depend entirely on IP transmission, which means even minor packet loss leads to jitter, dropped words, or failed calls. When Iran throttles or blocks VoIP packets, these apps become completely useless.
Mytello uses a hybrid model: calls are initiated through the app using a mobile data connection or Wi-Fi, but they are completed via regular phone lines (GSM or landline). This makes the app resilient against government-level VoIP blocks.

Call Quality & Reliability When Networks Are Overloaded
Calls made through Mytello benefit from carrier-grade routing, HD voice codecs, and global telecom partners. In contrast, apps like WhatsApp suffer from jitter, latency, or outright failure under network throttling.
Because Mytello maintains redundant carrier paths, it automatically selects the best available line to Iran. You’re not calling through an app to another app, you’re placing a real phone call, just at a fraction of the traditional cost.
