Staying connected while abroad is crucial, whether for work, leisure, or emergencies. For UK travellers, O2 is a familiar network, but international roaming can be costly and unpredictable. This is where Simify steps in with pre-paid, contract-free eSIMs offering global coverage at affordable rates. In this article, we compare O2 roaming vs Simify to help you make the right decision before your next trip.
About O2 Roaming
O2 offers international roaming for its mobile customers, allowing them to use their UK allowances abroad in certain regions. Within the EU, O2 continues to provide roaming at no extra cost as part of its "Europe Zone" policy, but charges can escalate quickly when travelling outside Europe.
O2 Roaming Zones and Charges
O2 divides the world into several zones for roaming pricing:
- Europe Zone: Roam at no extra cost in EU countries.
- Rest of World Zones: Daily charges or pay-as-you-go rates, depending on destination.
For example, if you're travelling to the USA, you might be offered a daily roaming pass, or be charged per MB, minute, or text. These costs add up quickly if you're a frequent data user.
Limitations of O2 Roaming
Despite the convenience, O2 roaming has some notable limitations:
- Data limits: Even in the Europe Zone, O2 enforces a "Fair Usage" policy with reduced speeds and caps after a certain limit.
- High costs: Outside Europe, you may face hefty fees if you forget to activate a roaming pass or exceed data limits.
- Manual activation: Some destinations require activating specific bolt-ons or passes, creating confusion.
What Is Simify?

Simify eSIMs work on eSIM-compatible phones and are especially popular among travellers looking for cost-effective, reliable mobile data abroad.

Advantages of Simify for Travellers

- No roaming fees: You pay only for the data you use upfront, with no surprise charges.
- Easy setup: No need to queue for a local SIM or wait for a courier; receive your eSIM instantly via email.
- Global coverage: Use one provider for multiple countries—perfect for multi-stop trips.
- Flexible plans: Choose plans by duration and data volume to suit your travel needs.
Real Use Case Comparison
Let’s consider a 10-day trip to Thailand and Vietnam.
With O2: You'll need to check if your plan supports roaming in Asia. Likely, you’ll need to activate a bolt-on. You might pay a daily fee or face high pay-per-use charges.
With Simify: You choose an Asia plan with 6GB for 10 days, pay once, activate in 2 minutes, and enjoy uninterrupted coverage in both countries.
Coverage and Speed Differences
O2 relies on local partner networks, which may offer good coverage but variable speeds depending on your location and roaming agreements. Simify, on the other hand, partners with Tier 1 carriers in each destination to ensure optimal speed and reliability. In many cases, this results in better 4G or even 5G coverage than traditional roaming.
How to Switch to Simify
Switching to Simify is easy:
- Check that your phone supports eSIM (most recent iPhones and Android flagships do).
- Visit Simify.com and choose your destination and plan.
- Purchase the eSIM and receive your QR code instantly via email.
- Scan the QR code to activate your plan before you leave or upon arrival.
If you're a frequent traveller or heading outside the EU, Simify offers more transparency, cost-efficiency, and convenience than O2 roaming. While O2 is suitable for short, casual trips within Europe, it becomes limiting once you venture beyond the continent. Simify removes the hassle of managing roaming settings, watching your usage, or fearing surprise bills. It’s travel-friendly, budget-friendly, and future-ready.
Before you take off make sure to check with local government of the travel status.
