In this guide, we look at the features, important small print and how to work out whether the offer is actually good value.

What is the Lebara 100GB MSE Exclusive Monthly Plan?
This special Lebara SIM-only plan offers 100GB of mobile data, aimed at people who want a substantial allowance without paying for a new handset. The page supplied for this article is labelled ‘100GB MSE Exclusive Monthly Plan’. The offer is advertised at £5.36 per 30 days for the first nine months, followed by £11.90 per 30 days. That’s a 55% introductory discount against the standard rate. Over the first twelve 30-day periods, the total is £83.94, compared with £142.80 at the regular price throughout, a saving of £58.86. Always check the price and terms at checkout because offers can change.
Is 100GB of mobile data enough?

For many people, 100GB is a generous monthly allowance. It can cover frequent social media use, music streaming, navigation, video calls and a fair amount of video streaming when away from Wi-Fi. Heavy use of high-resolution video, mobile hotspot connections or large downloads can still use it quickly. If you work from home on Wi-Fi most days, you may not need this much data. If you commute, travel or regularly use your phone as a hotspot, the larger allowance can be valuable. Look at your current mobile data usage in your phone settings or existing network account before switching. Paying for more data than you need is not automatically a saving.
Vodafone coverage and 5G access
Lebara operates on Vodafone’s UK mobile network. This is an important detail because coverage depends on where you live, work and travel, not just the headline price. Lebara says its plans include 5G, provided you have a compatible phone and are in a covered area. A strong 4G connection may be more useful than a patchy 5G signal, so check the coverage map for your home, workplace and regular routes. Mobile performance can also vary indoors and at busy times. If your current provider has poor reception, it is worth checking whether Vodafone coverage is genuinely better before moving your number.

Unlimited UK calls and texts
The 100GB offers currently advertised by major comparison services include unlimited UK minutes and texts. That makes the plan straightforward for people who still make regular phone calls as well as using messaging apps. However, premium-rate numbers, some special services and international calls may have separate terms. Check the plan’s full allowance details before ordering, particularly if you regularly call overseas. Lebara’s standard plans often include international minutes, but the amount and eligible destinations vary between offers. We would rather readers check the specific MSE plan than assume every standard Lebara benefit applies unchanged.
EU roaming and travelling abroad

One attraction of Lebara is its included roaming in supported destinations. Lebara currently advertises roaming across the EU and India, subject to fair-use restrictions and a data cap of up to 30GB depending on the plan. This does not mean the entire 100GB UK allowance is necessarily available abroad. Travellers should read the destination list, fair-use rules and any special conditions before leaving the UK. Roaming outside included destinations can cost extra or require an add-on. For people who take a couple of European holidays each year, included roaming may be a meaningful benefit compared with plans that charge a daily fee.
No long contract and no annual price hikes
Lebara promotes flexible 30-day rolling plans with no annual price increases and no credit checks. That is appealing if you want the option to change provider rather than commit for 12 or 24 months. But promotional rates are a separate issue: a plan can have no annual price rise and still increase from a discounted introductory price to its advertised standard rate after the offer period. Read the confirmation screen to find out exactly when that happens. If the plan is genuinely rolling monthly, you should be able to stop renewing or switch when you find a better option, subject to the specific terms. Flexibility is useful only if you keep track of the price.

Effective price over 12 months: approximately £7.00 per 30 days
Effective cost over 12 consecutive 30-day billing periods: £6.995 per period, approximately £7.00. The calculation is (9 × £5.36) + (3 × £11.90) = £83.94 total. This is an average across twelve 30-day periods (360 days), not a fixed £7 monthly tariff or a 12-month contract. After the nine discounted periods, the plan costs £11.90 every 30 days, subject to the offer terms.
A cheap introductory rate can make a SIM deal look irresistible, but the standard price matters just as much. For this specific offer, nine 30-day periods at £5.36 cost £48.24. Three more periods at £11.90 cost £35.70, making the total for twelve 30-day periods £83.94, or about £7.00 per 30 days on average. At the standard £11.90 rate throughout, twelve periods would cost £142.80, so the introductory saving totals £58.86. Use the same calculation with the actual amounts shown at checkout: multiply the introductory rate by its number of months, add the remaining months at the standard rate, and divide by 12. That makes it much easier to compare plans fairly. Our guide to saving money at home covers other regular bills worth checking.
Can you keep your current mobile number?

Yes. Lebara says you can bring your existing UK mobile number with you. Request a Porting Authorisation Code, or PAC, by texting PAC to 65075 from your current SIM. The code is normally valid for 30 days. Once you have received and activated your new Lebara SIM, follow the instructions to transfer the number. You should not need to cancel your old account manually if the port is handled correctly, although any outstanding contractual charges from your existing provider remain your responsibility. Before switching, check whether your phone is unlocked and whether your current agreement includes early termination fees.
Who should consider this deal?
This offer is most interesting for people who use a lot of data, already own a suitable unlocked phone and want to reduce the cost of mobile service. Students, commuters, frequent travellers and households reviewing their monthly subscriptions may all find a high-data SIM useful. It is less compelling for someone who uses only a few gigabytes each month, especially if a smaller allowance is available at a much lower long-term price. Also consider whether you need eSIM rather than a physical SIM and check availability for your device. Our household bills check-up can help put a mobile saving into a wider monthly budget.

Our verdict on the Lebara 100GB offer
A 100GB Lebara SIM could be an attractive alternative to an expensive traditional mobile contract, particularly if Vodafone coverage is good where you spend time and you value the freedom of a rolling plan. Included roaming and 5G access add to the appeal. The main caution is the promotional price: check both the initial rate and the price after any introductory period, and confirm the full terms for this exact MSE offer. We have not tested the network ourselves. The offer prices were provided for this specific plan and should be checked at checkout. If the numbers suit your usage and budget, it is well worth comparing against what you currently pay. Prices, promotions and availability can change at any time.
