Stay connected with local messaging apps, curated for travelers visiting United Kingdom.
WhatsApp is the only additional messaging app most visitors should consider installing.
The UK's most commonly used smartphone app, useful for hosts, tour operators, friends and some businesses.
Ofcom's Online Nation 2025 report identifies WhatsApp as the most commonly used smartphone app among UK adults, so it is often used by accommodation hosts, tour operators, friends and small businesses alongside ordinary calls, text messages and email. Your existing international WhatsApp account continues to work with its original number, and you do not need a UK SIM or local bank account. Confirm a business's number through its official website or booking message before sharing personal details. A profile name or logo is not proof that an account belongs to a hotel, airline, bank or government service.
Do not move a payment outside a trusted booking platform simply because someone contacts you through WhatsApp, and never share a one-time login code. Emergency services are not contacted through WhatsApp. Call 999 or 112 when life or property is in immediate danger, and use 101 for a non-emergency police matter. Ordinary SMS remains useful for one-time verification from banks, transport services and reservation platforms, so keep roaming enabled for incoming texts or use a travel SIM that can receive them.
Other messaging apps such as Telegram and Signal operate normally but are not UK-specific travel requirements.
