How to activate a Lebara SIM

Activating a Lebara SIM is quick once you know the steps, but a few things reliably trip people up: there's no code to type in, the referral discount has to show before you pay, and the cash reward (for the person who referred you) is deliberately slow. This guide walks you through activation from the moment your SIM arrives, explains what to do if your number isn't transferring or your discount isn't showing, and shows how to lock in 50% off your first three months by activating through a referral link.

Activating a Lebara SIM is quick once you know the steps, but a few things reliably trip people up: there's no code to type in, the referral discount has to show before you pay, and the cash reward (for the person who referred you) is deliberately slow. This guide walks you through activation from the moment your SIM arrives, explains what to do if your number isn't transferring or your discount isn't showing, and shows how to lock in 50% off your first three months by activating through a referral link.

Before you start: order through a referral link for 50% off

The single most important thing to get right happens before activation, not after. If you are a new Lebara customer, ordering your SIM-only plan through a referral link gets you 50% off for your first 3 months, after which the plan moves to its standard price. There is no code to type in — Lebara's Refer & Earn scheme is link-based (run through Aklamio), so the discount applies automatically at checkout once you have opened the link and chosen a SIM-only plan. The catch is that you cannot add it retroactively: if you have already ordered at full price, the discount cannot be bolted on afterwards. So if you have not committed yet, open the referral link, pick a 30-day rolling or 12-month SIM-only plan, and confirm the 50% shows on the order summary before you pay. In the interest of being upfront: when you stay active for the qualifying period, the person who referred you may receive a small cash reward from Lebara — but your 50% saving is the same either way.

Step 1: Insert the SIM and pick the right size

Lebara SIMs typically arrive as a multi-size 'punch-out' card, so you snap out the size your phone needs — standard, micro, or nano (nano is the smallest and what most modern phones use). Power your phone off, insert the SIM into the tray, and turn it back on. If your handset supports eSIM, Lebara may instead let you activate digitally by scanning a QR code or adding the eSIM in your phone's mobile-data settings, which skips the physical card entirely. Either way, make sure the phone is unlocked to all networks — if it is still locked to a previous provider, the Lebara SIM will not register, and you will need your old network to unlock it first.

Step 2: Activate online or top up to bring the SIM to life

A physical Lebara SIM is dormant until you activate it. The cleanest route is to register or sign in on lebara.co.uk (or in the Lebara app), enter the activation or SIM number printed on the card, and either select your plan or make your first top-up. If you ordered a SIM-only plan through a referral link, your plan and the 50% discount should already be attached to the order — you are simply confirming activation. Once activated, the network needs a short while to provision the SIM; this is usually minutes but can occasionally take up to 24 hours. A handy way to check it is live: restart the phone, then look for signal bars and try sending a text or loading a webpage on mobile data (with Wi-Fi off). If nothing connects after a restart and a reasonable wait, that points to a provisioning delay rather than anything you have done wrong.

Step 3: Keep your old number (PAC transfer) and set up the internet

If you want to keep your existing number, you do not have to decide on day one, but the process is simple. Text the word PAC to 65075 from your old SIM while it still works; you will receive a PAC code (a Porting Authorisation Code) plus details of any outstanding balance. Give that PAC to Lebara through your account or the app, and your number will transfer across — usually within one working day — without losing service in the meantime. Note you will keep using the temporary Lebara number until the switch completes. While you are in settings, if mobile data is not working after activation, check that your phone has picked up the Lebara APN (internet) settings; most modern phones configure this automatically, but if not, lebara.co.uk lists the correct APN values to enter manually. A restart after saving them usually does the trick.

Troubleshooting: discount not showing, no signal, or the 60-day wait

Three issues come up again and again. First, 'my discount isn't showing': this almost always means the referral link was not opened directly before checkout, you are not a new customer, you picked a non-qualifying product, or an ad-blocker or cleared cookies stripped the tracking. The fix is to start fresh from the referral link, choose a SIM-only plan, and verify the 50% appears before paying — there is no manual code to fall back on. Second, 'no signal or no data after activation': power-cycle the phone, confirm the SIM is seated and the handset is unlocked, allow up to 24 hours for provisioning, and check your APN settings. Lebara runs on the Vodafone network with around 98% UK population coverage and 5G at no extra cost on compatible phones, so persistent dead signal usually points to a SIM, handset-lock, or provisioning issue rather than coverage. Third, the '60-day wait' confusion: this only affects the referrer's cash reward, not you. Your 50% discount applies the moment you check out. The referrer is paid (to bank or PayPal, within about 60 days) only after you have activated and stayed active through the qualifying window — and cancelling within 60 days voids their reward. Your discount and your service are never held up by that timer.

After activation: international calls, EU roaming and managing your plan

Once you are live, the features Lebara is best known for kick in. SIM-only plans include calls to 50+ countries at no extra cost, with allowances that scale by plan tier (up to unlimited international minutes on the top plans) and low rates or International Call Passes for other destinations — always confirm your specific country's current allowance or rate on lebara.co.uk, since included-country lists change. All plans also include free EU roaming across around 36 European destinations (a data fair-use cap applies on unlimited plans). Day to day, the Lebara app is the easiest place to track your usage, top up, switch plans, or cancel — the 30-day rolling SIM-only plans are no-contract, so you can change or leave monthly. Entry plans start from around £5 a month, there is generally no credit check (which makes Lebara popular with students and recent arrivals), and if you ever want to refer someone yourself, you can grab your own link from the Refer & Earn dashboard once your SIM is active.
