About Lyca Mobile

Lyca Mobile is a SIM-only network built around cheap international calls, running on O2's network. It leans on pay as you go and flexible 30-day bundles, so there is no long tie-in to worry about. It suits value hunters and anyone who phones abroad often. Plans start from £10.00 a month. Compare the live Lyca Mobile deals below.

Quick facts

  • Runs on O2's network, so coverage matches O2 in your area
  • Built around cheap international calls
  • Pay as you go and flexible 30-day bundles
  • Aimed at value and international callers
  • Keep your existing number with a PAC code

What network does Lyca Mobile use?

Lyca Mobile uses O2's network for your calls, texts and data, so the signal you get tracks O2 in your area. Where O2 has 5G, you can expect 5G too on a suitable plan and phone. Because coverage is the thing that makes or breaks a SIM, check O2 signal at home, at work and on your commute before you commit.

Lyca Mobile plan types explained

There are two main ways to use Lyca Mobile. Pay as you go lets you top up and only pay for what you use, which is handy if your habits are unpredictable. Flexible 30-day bundles renew monthly and can be changed without a long contract behind them. The live deals above show the bundles currently on offer, with their data and call allowances.

Perks and features

The headline draw is cheap international calling, which is why Lyca Mobile appeals to people with family or business contacts overseas. Pairing that with no-commitment 30-day bundles keeps things simple and easy to leave. For exactly which countries and rates apply, and what each bundle includes, read the plan terms in the comparison above rather than assuming, as inclusions vary by deal.

Who Lyca Mobile suits

Lyca Mobile is a sensible shout if you call abroad regularly and want to keep the monthly cost low. The flexible bundles also suit anyone who would rather not sign up to a lengthy deal. It is less of a fit if you want big perks, loyalty schemes or in-store help, since the offer here is value-led and stripped back rather than feature-heavy.

Lyca Mobile vs other O2 networks

Lyca Mobile, giffgaff, Sky Mobile and Tesco Mobile all sit on O2's network, alongside O2 itself, so coverage is broadly the same across them. The difference is in the extras: Lyca Mobile focuses on cheap international calls and value, while the others lean on rewards, rollover data or contract choice. Compare on price and the perks you would actually use.

Pros

  • Runs on O2's network
  • Built around cheap international calls
  • Flexible 30-day bundles and pay as you go
  • Keep your existing number with a PAC code

Cons

  • Coverage depends on O2, which varies by area
  • Fewer loyalty perks than some rival O2-based networks
  • Value-led offer rather than feature-rich

Our verdict

Lyca Mobile is worth a look if you make a lot of international calls and want O2 coverage on a low-cost, no-commitment bundle.
