Best SIM card for international students UK

A UK number is the first thing you need after you land. You use it for your bank, your university portal, maps, taxis, food delivery and calls to your family. Public wifi is patchy, and roaming on your home SIM can get expensive fast.

The good news: sorting a UK SIM is easy and cheap. Many plans start at £5 for 30 days. Many need no contract and no credit check. You do not have to wait for a UK bank account either. Pay-as-you-go (PAYG) needs no credit check, while monthly contracts usually need a UK bank account.

One rule matters most. Your phone must be unlocked. If it is locked to a home network, ask that network to unlock it before you fly. Do this first and everything else gets simple.

Run through these five checks and you will pick the right plan in minutes.

1. Unlocked phone. Every plan in this guide needs one.
2. Credit check. Choose plans that say no credit check, especially in your first weeks.
3. Contract length. A 30-day rolling plan lets you leave any time. A 12 or 24-month plan can cost less each month, but you are tied in.
4. Data you really use. Students who stream and video call need much more than 5GB. Light users can save money.
5. Calls home. Check how many international minutes a plan includes, and check that your country is covered.

Need an eSIM? Your phone must support eSIM and be unlocked. An eSIM arrives as a QR code, so you can set up before you even leave the airport.

Chattr keeps it simple. It has one plan, Freedom One: unlimited 5G data, calls, texts, roaming and hotspot. It costs £15 a month for months 1–5, £14 for months 6–11 and £13 from month 12. The price falls the longer you stay. There is no contract, no credit check and no price hikes, and it runs on the O2 network with O2 Priority benefits.

You can get an eSIM sent digitally, or a physical SIM in 1–3 days. Travel SIM from £2.50 is listed as coming soon.

New UK customers aged 18+ with an unlocked phone can use code HONEST75 from our sister site HonestCodes. It takes 75% off your first month, so unlimited 5G costs £3.75, then £15. It applies to the first month only.

Follow these steps and you will be online fast.

1. Unlock your phone before you travel. Ask your home network.
2. Pick your plan from the table below. Choose a 30-day plan if you want freedom.
3. Choose eSIM or physical SIM. An eSIM needs an eSIM-compatible, unlocked phone. It arrives as a QR code. A physical SIM comes by post, so order early or buy it with a UK address in mind.
4. Enter any code at checkout and check the new price before you pay.
5. Activate. Scan the QR code for an eSIM, or put in the SIM and follow the steps.
6. Keep your old UK number? Lebara and 1pMobile say to text PAC to 65075 from your old phone.
7. Test it. Make a call, open maps and check your data.

Keep your home SIM safe. Many students keep it for banking codes from home.
