Does Lyca Mobile Offer Unlimited Data?
Yes — Lyca Mobile offers “unlimited data” plans in the UK, usually as SIM-only deals (30-day rolling) and longer 12- and 24-month plans. Like all UK providers, Lyca’s unlimited plans are normally subject to a fair usage policy, which means extremely heavy usage may be managed (for example, to prevent network abuse).
Lyca Unlimited Data Prices
The cheapest Lyca unlimited deals are often promotional and can change weekly. Here’s a clean comparison table you can keep updated.
| Plan type | Term | Typical price range | What you get | Best for |
|---|---|---|---|---|
| Unlimited SIM | 30 days (rolling) | From £25 / 30 days | Unlimited data + UK calls/texts (typical) + intl minutes (often) | Flexibility, short-term |
| Unlimited SIM | 12 months | From £20 / month | Unlimited data + better monthly value vs rolling | Regular heavy users |
| Unlimited SIM | 24 months | From £18 / month | Unlimited data + lowest long-term price (often) | Best long-term savings |
What’s Included With Lyca Unlimited Data?
Is unlimited data really unlimited?
In the UK, “unlimited” usually means you won’t hit a normal monthly cap, but providers may apply fair usage rules to stop extreme or commercial-style usage. If you use data for constant hotspotting or non-stop high-bandwidth activity, you may see speed management or restrictions.
Does Lyca unlimited include 5G?
Lyca typically advertises 4G/5G access on eligible plans and devices, but your real-world experience depends on coverage where you live. If 5G matters, check coverage before buying (see the coverage section below).
Does Lyca include roaming?
Some Lyca plans include EU roaming, but roaming allowances and rules vary by plan and promotion. Always check the current plan details and terms before travelling.
International minutes
Lyca often includes international calling minutes on many bundles, which is one reason it’s popular versus mainstream networks. Again: inclusions depend on the exact plan and current promotion.
Lyca Bundle Codes & How to Activate Unlimited Data
A lot of Lyca searches are really about activation. Here are the standard ways people activate Lyca unlimited data:
How to activate a Lyca unlimited plan (step-by-step)
- Buy the unlimited plan online (or add it via the Lyca app / account).
- Insert your Lyca SIM (or enable eSIM if supported on your chosen offer).
- Restart your phone and ensure mobile data is enabled.
- If needed, activate the bundle using a USSD code (see below) or via your online account.
- Enable auto-renew if you want the plan to roll over each month.
What is the *137 code on Lyca Mobile?
*137# is a common Lyca USSD code used to access bundle/plan options on your handset (for example, to manage or check bundles). Lyca also uses other short codes depending on the country and the service, so if a code doesn’t work, use the Lyca app/account or check the official help pages.
“Lycamobile 10/15/20/25/30 bundle code unlimited data” — what does this mean?
These searches usually refer to bundle names or price-point bundles (e.g., “£10 bundle”, “£20 bundle”) and the dial codes or activation steps tied to them. The exact bundle codes and bundle availability can change frequently, so the safest approach is:
- Buy/activate your bundle through your Lyca account (most reliable)
- Use the USSD menu (e.g., *137#) for bundle options if supported
- Check the current bundle list on Lyca’s official deals pages (linked below)
How do I check my Lyca unlimited data?
The easiest method is via your Lyca account/app or bundle management menu on your phone. If you’re unsure, check your active bundle status and renewal date rather than “remaining data” (because unlimited plans won’t show a typical cap).

Network & Coverage: Is Lyca Signal as Good as EE?
Lyca is an MVNO (a network that runs on another provider’s infrastructure). In practice, your experience will depend on:
- Coverage in your area (4G/5G availability)
- Indoor signal (homes can vary massively street-to-street)
- Network prioritisation at peak times (can affect MVNO performance)
If you’re choosing Lyca mainly for unlimited data, it’s worth doing a quick coverage check before buying — especially if you rely on mobile data indoors.
Best Alternatives to Lyca Unlimited Data
If Lyca isn’t the right fit, here are common “like-for-like” alternatives people compare in the UK:
| Provider | Why consider it | Best for | Check deals |
|---|---|---|---|
| Lebara | Often strong value + international minutes, simple plans | International calling + budget plans | Compare Lebara deals |
| Smarty | Good value, flexible 30-day plans | Rolling plans, easy cancellations | Compare Smarty deals |
| VOXI | Social/video perks on some plans | Heavy social media users | Compare VOXI deals |
| EE / O2 / Vodafone / Three | Direct networks with premium perks (usually higher price) | Best coverage / perks priority | See best unlimited deals |
Lyca vs Lebara: which is better?
If you want the simplest answer: both can be great value for money, especially if international minutes matter. The “better” choice usually comes down to coverage where you live, the exact bundle on offer today, and whether you prefer a rolling 30-day plan or a longer-term contract for a lower monthly price.
Pros & Cons of Lyca Mobile Unlimited Data
Pros

- International minutes are common on bundles
- Rolling 30-day options (more flexible than big networks)
- Simple, SIM-only setup
Cons
- “Unlimited” still follows fair usage policies

Is Lyca Unlimited Data Worth It?
Lyca unlimited data is usually worth it if you’re a heavy data user who wants the lowest possible monthly cost and doesn’t need premium perks (like handset upgrades, roaming-heavy travel benefits, or bundled subscriptions).
It may not be ideal if you rely on flawless indoor signal, hotspot constantly, or want a premium network experience. In those cases, compare against the main networks or a strong alternative MVNO.
