Monzo’s new eSIM network offers a 30% loyalty discount, but there’s a catch. Discover why “no-contract” plans might actually expose you to more price hikes.
Key Takeaways
What: Monzo Mobile is a new eSIM-only network for banking customers.
Why: It rewards long-term users with 5% annual discounts, capped at 30%.
How: Sign up via the Monzo app for no-contract plans starting at £8/month on the Virgin Media O2 network.
Monzo is moving beyond banking to launch its own mobile network, using a model that rewards customers for staying put rather than switching. With more than 15 million customers already using the bank, this shift into the telecom space aims to simplify how people manage their digital lives by housing phone plans and bank balances under one roof.
The Flexibility Paradox: Why No-Contract Could Cost More
Standard industry wisdom suggests that “no-contract” plans are the ultimate win for consumers because they offer total freedom. However, there is a catch that most early reviews have overlooked. Since 2025, UK regulators have significantly tightened rules regarding mid-contract price hikes for fixed-term agreements. Because Monzo’s plans are monthly rolling agreements with no exit fees, they sidestep the traditional “contract” definition.
This creates a paradox: the freedom to leave at any time also gives Monzo the freedom to change its pricing at any time. While traditional providers are now under heavy pressure from Chancellor Rachel Reeves to limit mid-contract increases, Monzo has not committed to avoiding annual inflation-linked price rises. This flexibility “cuts both ways”. While you aren’t trapped in a 24-month deal, you also lack the price certainty that a fixed-term contract provides. You are essentially betting that your loyalty discount will outpace any future price adjustments the bank decides to make.
Decoding the Loyalty Discount
The core of Monzo’s pitch is a “loyalty discount” designed to challenge the traditional mobile model that typically penalizes long-term customers. The math is straightforward: customers receive a 5% discount on their monthly bill for every year they stay, with the reduction capping at 30% after six years.
The service offers three distinct tiers:
- £8 per month: 10GB of UK data.
- £12 per month: 30GB of data, including 10GB for roaming in Europe.
- £20 per month: Unlimited UK data and 26GB of global roaming.
While these prices are competitive, they are not the lowest on the market. Comparison data shows that providers like Spusu offer 10GB for £5.90, and ID Mobile provides unlimited data for £15. Monzo is banking on the idea that customers will pay a slight premium for the convenience of managing their SIM through an app they already use daily.
The eSIM-Only Infrastructure
Monzo is skipping physical SIM cards entirely. The service is “eSIM-only,” meaning it is activated digitally through your phone’s settings rather than through a piece of plastic sent in the post. This hardware-free approach is powered by the telecommunications technology provider 1GLOBAL and runs on the Virgin Media O2 network, which covers 99% of the UK population.
While this makes the setup process almost instantaneous, it limits the service to modern smartphones that support eSIM technology. For those with older devices, the bank’s mobile entry will remain out of reach.
One App to Rule Everything
The true value for a Monzo user isn’t just the data—it’s the integration. By managing the mobile plan within the existing banking app, users can track their data usage, monitor roaming costs, and view their mobile spending alongside their grocery or rent payments in real-time.
Monzo also promises to bring its high-speed customer service to the mobile world, offering 24/7 in-app support from real people. Features like visual voicemail, Wi-Fi calling, and mobile hotspotting are included across all plans.
The FinTech Expansion
Monzo is not alone in this move. Financial competitors like Revolut have already launched mobile services, signaling a trend where digital banks attempt to become “super-apps” that handle every recurring monthly bill.
The service is scheduled for a full rollout in the summer of 2026, and the bank has already opened a waitlist for its 15 million customers to register their interest. Whether the promise of a 30% loyalty discount is enough to pull users away from cheaper, smaller virtual networks remains to be seen, but Monzo is clearly betting that simplicity—and a little bit of math—will win over its “legion of loyal customers”.
