Countries Where Internet Calling Is Restricted, and Why

Which countries restrict internet calling?

A small number of countries block or licence voice calling over the internet at the network level, so the restriction applies to everyone on that network regardless of which app they use. The clearest and most stable cases are the Gulf states and China.

Country	What is restricted	Status
United Arab Emirates	Consumer VoIP voice and video: WhatsApp, FaceTime audio, Skype, Messenger calls	Long-standing; licensed alternatives permitted
Qatar	WhatsApp and similar app calling	Long-standing, enforcement varies
Oman	App voice and video calling; messaging generally works	Long-standing
China	WhatsApp blocked entirely, along with most non-domestic messaging platforms	Since 2017
Kuwait, Bahrain	App calling, applied inconsistently	Intermittent
Egypt, Morocco, Pakistan, Myanmar	Periodic restrictions, sometimes temporary	Varies over time

Two corrections to advice that circulates widely. Saudi Arabia lifted its ban on VoIP calling in September 2017 and app calling has been permitted since; pages still listing it as blocked are out of date. Morocco's 2016 block was reversed after public and regulatory pressure. This category changes, which is why any list including this one should be treated as a starting point rather than a current legal position.

Why are these calls blocked?

The stated reasons are regulatory and licensing. The practical reason is revenue.

In the Gulf states, international voice is a substantial revenue line for state-linked operators, and it is priced accordingly — an international minute from a UAE mobile can cost several dirhams. An app that carries the same conversation over a data connection at no marginal cost removes that revenue entirely. Regulators in these markets treat voice calling as a licensed telecommunications service, and an unlicensed app providing it is, in that framing, operating outside the licensing regime.

The consequence is a licensing route rather than a blanket prohibition. The UAE's Telecommunications and Digital Government Regulatory Authority permits VoIP from licensed providers, and licensed apps — Botim and similar — operate legally there, usually as a paid service through the local operators. The restriction is not on the technology; it is on who is permitted to sell it.

China's situation is different in character. WhatsApp is blocked as part of a broad restriction on foreign messaging and social platforms rather than as a telecoms licensing measure, and domestic alternatives dominate.

How is the block actually implemented?

Mostly by deep packet inspection at the network operator. Traffic is examined for the signalling and media patterns that voice calling produces — SIP messages, RTP streams, or the specific handshake signatures of individual apps — and matching flows are dropped or throttled.

Three things follow from this that people find counter-intuitive.

Messaging usually still works when calling does not. Text, photos and voice notes travel as ordinary encrypted data and look nothing like a live media stream. A voice note recorded and sent as a file is a completely different traffic shape from a live call, which is why WhatsApp remains useful in Oman and Qatar for everything except calling.

The block follows the network, not the account. It applies to whoever is connected to that operator, including visitors on roaming and on hotel Wi-Fi. It is not a property of your phone or your SIM.

The failure mode is usually a call that rings and never connects, or connects and carries no audio, rather than a clear error message. This looks identical to a bad connection, which is why travellers frequently spend an evening troubleshooting Wi-Fi when the network is doing exactly what it was configured to do.

Does this affect Telvio?

Yes, potentially, and the honest answer matters more here than a reassuring one.

Telvio places calls over a data connection. On a network that inspects and drops voice traffic, Telvio's calls can be dropped for the same reason WhatsApp's are. Being a call to an ordinary phone number rather than an app-to-app call does not exempt it: the block is applied on the leg leaving your device, before the call reaches any telephone network.

We do not publish claims about circumventing national restrictions, and this page will not tell you how to. What we can say plainly is what the service is: an app that calls real phone numbers over an internet connection, which requires that connection to permit voice traffic. Where it does not, the app will not work well, and that is a limitation of the environment we cannot engineer around.

What actually works in a restricted country

Four options, in rough order of reliability.

A local SIM and ordinary phone calls. The local telephone network is not restricted — that is the point of the restriction. Buying a local prepaid SIM and dialling normally works everywhere, and for calls within the country it is usually cheap. International calls from it are the expensive thing the restriction protects.

A licensed local calling app. In the UAE, Botim and similar licensed services operate legally and are widely used by residents. They are typically paid, either directly or through an operator add-on.

Messaging instead of calling. Voice notes are an underrated substitute. They are asynchronous, they carry tone in a way text does not, and they pass through networks that block live calls.

Roaming on your home SIM. Your home carrier's roaming service places calls through the local network as ordinary calls, so it is unaffected by app restrictions. It is also the most expensive option by a wide margin — see avoiding roaming charges for what those charges actually look like.

How to tell a block from a bad connection

They present almost identically, which is why people misdiagnose this constantly. Four checks separate them in a couple of minutes.

Does messaging work while calling does not? If text and photos send instantly but every call fails, that is a block. A genuinely poor connection degrades both.

Does the call fail the same way every time? Blocks are deterministic — the call rings and never connects, or connects silently, on every attempt. A bad connection is variable: sometimes it works, sometimes it drops midway.

Does a different app fail identically? Try two unrelated calling apps. If both fail in the same way on the same network, that points at the network. If one works and another does not, it is more likely an app or account problem.

Does it work on a different network? Move from hotel Wi-Fi to mobile data, or to a different Wi-Fi network entirely. A block applied by one operator will not follow you to another — though in a country where all operators apply it, this test will come back the same everywhere, which is itself informative.

Run these before spending an evening on router settings. The diagnostic steps in call quality troubleshooting apply once you have established that the network is not deliberately refusing.

Before you travel

Three things worth doing in advance, because all of them are harder once you have arrived.

Check the current position, not a list. These restrictions change with regulatory decisions and no third-party page tracks them reliably. The operator's own website and recent posts in expatriate forums for that specific city are better sources than a listicle.

Agree a fallback with the people you call. Deciding in advance that you will send voice notes, or that they will call you on a local number, removes the evening of confusion.

Do not rely on any calling app as your only route to emergency services. This is true everywhere and doubly true where app calling is restricted — see emergency calls and internet calling apps.

Why the restriction rarely lasts forever

The economic argument that supports these blocks is weakening, and the direction of travel across the last decade has been towards removal rather than expansion.

Three forces work against them. Operators increasingly earn more from data than from voice, which makes protecting voice revenue a shrinking priority — this is the dynamic that ended the restrictions in Saudi Arabia and Morocco. Business pressure is substantial, because a country hosting international companies and conferences cannot easily block the video calling those companies run on. And the blocks are unpopular with exactly the population they most affect, which in the Gulf states is a large migrant workforce whose families are abroad and for whom the cost difference is not marginal.

The counterweight is that licensing creates its own constituency: once a licensed paid alternative exists and is generating revenue, there is a commercial interest in the unlicensed ones staying blocked.

What this means practically is that a restriction is a current fact rather than a permanent property of a country, and both directions of change happen. Guidance more than a year or two old should be checked rather than trusted — including this page, which states the position as of August 2026.

Is using a VPN to get around it legal?

That depends on the country and it is a question worth taking seriously rather than assuming. Several of the states listed above regulate VPN use, and in some of them using one to access a restricted service carries penalties. The UAE's cybercrime law, for instance, addresses the use of technical means to access services in a way that contravenes regulation.

We are not in a position to advise on any specific country's law, and generic advice found online is frequently wrong about it. If this matters to you, the local regulator's published guidance and qualified local advice are the sources — not a calling app's help page and not ours.

Bottom line

The UAE, Qatar and Oman restrict consumer internet calling at the network level, China blocks WhatsApp outright, and several other countries apply restrictions intermittently. Saudi Arabia and Morocco reversed theirs and are frequently still listed as blocked in out-of-date guidance.

The restriction is applied by the network operator to the traffic leaving your device, which means it affects every calling app on that network — Telvio included — while leaving messaging and voice notes working. What reliably works is the local telephone network: a local SIM, a licensed local calling app, or roaming on your home carrier. Whether a VPN is a lawful option is a question about that country's law rather than about technology, and it deserves a better answer than an app's marketing page can give.
