UK expats living abroad find it crucial to maintain their +44 UK phone number. It ensures uninterrupted contact with family and friends without the burden of international call charges or roaming fees. And in today's modern times which requires that we constantly verify ourselves and 2FA-proof all our accounts, our phone number has become as important as our tax number. Having a UK phone number allows expats to easily manage calls and texts, their banks while avoiding the need for additional mobile devices, SIM cards, or contracts (more info).

In our company, we work alongside UK expats and have noticed where the free messaging apps have fallen short.

Banking: A UK phone number is indispensable for managing your financial affairs while abroad. It's the main vein for receiving SMS alerts and banking codes, vital for two-factor authentication and banking security. HSBC, RBC and Lloyds aren't going to verify your identity via a Whatsapp message. They'll need your real phone number (more info).

Her Majesty's Government Services:

As a UK citizen, you do not necessarily need a UK phone number for the government to contact you. The UK government provides various ways to contact them, including phone, email, and social media.

However, if you need to call the government from outside the UK, you will need to use the international dialing code +44 before the phone number. It means that some government services may have specific contact numbers or requirements, and may not be able to dial internationally to country in which expats have their local SIM.

Official Matters Over Casual Chats: Apps such as WhatsApp, Messenger, or Telegram can suffice for casual chats but fall short for official notifications and calls. Businesses, banks, and essential services by-and-large rely on traditional phone communication. Thus, a UK-based number is not just a convenience—it's a necessity for staying officially connected while overseas.

UK 2-way Calling and SMS Solutions for Expats in 2023

Scarce Choices, Vital Connections

Yes, even now in 2023 where there's all the craze about AI, the search for a VoIP and SMS app that can fully replace a UK SIM or landline, is a challenge. Despite the plethora of choice of messaging apps, only a few offer the two-way capability of calling and SMS with +44 phone number. Many expats are simply buying eSIMs and hope that their carriers fair usage policy doesn't block them for excess roaming. In practice, few eSIM holders make it through the cracks without being blocked.

eSIM and OTT apps aren’t enough

The evolution of eSIM and OTT (Over-The-Top) services has greatly impacted how people communicate. Here's a detailed look at the pros and cons of these services:



  • Space-Saving: An eSIM is built into the handset, saving physical space for other features like a larger battery or more storage.

  • Multiple Plans: eSIMs allow for multiple numbers and providers on the same device, ideal for personal, business, or travel plans without changing SIM cards. Simply toggle between eSIMs and you're connected to different carriers on the fly.


  • Portability Issues: Unlike physical SIMs, eSIMs cannot be easily transferred between devices. If a phone breaks or an upgrade is needed, transferring an eSIM can be more complicated and not all phone models support it.

  • Provider Switching: To switch providers while keeping the same number, a PAC code is still required, which can be a hassle, especially while abroad.

  • Roaming Restrictions: While many UK eSIMs offer EU roaming, carriers might restrict service if they detect the majority of usage is outside the UK, inevitably leading to number loss and making eSIMs unreliable for long-term travel or expat living.

  • Dual SIM Requirement: eSIMs require a modern phone that supports dual SIM functionality, which may not be ideal for everyone and can be tough to replace in a bind. When writing this article, only 30% of devices support eSIM.

OTT Apps (e.g., Whatsapp, Messenger, Viber, Telegram)


  • Global Connectivity: Apps like WhatsApp, Messenger, and Telegram provide easy communication across borders, allowing expats to stay in touch with family and friends. And they're free!


  • Online Limitation: OTT services require a stable internet connection, which can be a problem in areas with poor connectivity (more info).

  • Security Risks: Some OTT platforms may pose security risks, with the potential for cybercrimes such as phishing.

  • Lack of Official Use: Banks and businesses rarely use OTT apps for official communication and alerts, such as sending OTPs (one time passwords) or conducting secure transactions.

  • App Dependency: Both parties must have the app installed; it's not possible to contact someone outside the app network, limiting official or wider communication. Whereas with a telephone number, you can contact virtual anyone without additional apps.

Total UK users: 9 million
  • Pros: Offers reasonable call quality for one-on-one and group calls, with a user-friendly interface and global connectivity features like chat, calls, video calls, screen sharing, and group messaging (more info). Not a full OTT-app because it is possible to buy an actual UK phone number from Skype.

  • Cons: Dependent on a stable internet connection, with possible security concerns for business communications. UK phone numbers can only sending outgoing SMS, not incoming. Prices are high. Complicated legacy technology and decreasing users base. (more info).
