Olimit Tips & Tricks

30-day SIM Only deals offer great flexibility and no long-term commitment, making them ideal if you want to stay in control or avoid credit checks. However, longer contracts such as 12, 18, 24 months sometimes come with better discounts, extras, or faster network access. If you’re after freedom and short-term savings, 30-day plans are a solid choice — just make sure the data, minutes, and roaming fit your needs.

A 30-day SIM Only plan is perfect for people who want flexibility without commitment. It’s ideal if you’re between contracts, trying out a new network, visiting the UK, or if you’ve been declined for a contract. These plans usually don’t require a credit check and let you cancel or switch anytime — making them a smart choice for short-term or low-risk mobile use.

Best 30-Day SIM Only Deals in the UK

Flexible mobile plans without long contracts — perfect for visitors, students, and anyone who wants freedom over commitment.

Why Choose a 30-Day SIM Deal?

Whether you’re visiting the UK, staying temporarily, or just want to avoid annual contracts, 30-day SIM plans offer complete flexibility:

  • No credit checks — ideal for new arrivals or short-term residents.
  • Prepaid or rolling monthly — you’re in control of renewals.
  • Unlimited data options — stream, browse, and video call freely.
  • Keep your number — switch networks without losing your number (UK port-in supported).

Real-World Use Case

A postgraduate student arrived from Spain and needed a temporary UK number. Instead of signing up for a contract, they activated a 30-day SIM from Voxi — unlimited social data and easy top-up every month, with no paperwork or bills. It worked perfectly during their UK stay.

Who Should Consider a 30-Day Plan?

  • Tourists & temporary workers needing local mobile access for a few weeks or months.
  • International students settling into the UK but not ready for 12-24 month deals.
  • Expats & digital nomads looking for fast UK mobile data with roaming options.
  • Anyone between contracts or testing networks like EE, Vodafone, O2 or Three.

FAQs About 30-Day SIM-Only Plans

Do I need a UK address to get one?

No! Many providers like Lebara, Voxi, and Lyca allow you to buy with an international card and no UK address.

Can I keep the same SIM next month?

Yes. 30-day SIMs can be topped up or automatically renewed monthly. If you’re staying longer, just keep topping up.

Is there a credit check?

No credit check is required for prepaid or pay-as-you-go 30-day plans. Great for international users.

Can I use the SIM across Europe?

Yes — many UK providers include EU roaming and beyond. Look for EU roaming details on the plan, or this icon: Roaming Destinations.

Which phones are compatible?

All unlocked phones will work with UK SIMs. If your phone supports eSIM (iPhone XS or newer, Samsung Galaxy S20 or later), you can skip the plastic SIM entirely.
