If you’re looking for SIM only contract deals with unlimited internet in the UK, there are abundant options from major networks such as Vodafone, EE, O2, Three, Tesco Mobile, Smarty, iD Mobile, Giffgaff, Asda Mobile, Superdrug Mobile, and Honest Mobile. These plans provide unlimited data—often alongside unlimited calls and texts—and are available on various contract lengths, including flexible 30-day rolling, 12-month, and 24-month agreements[1][2].

Key points to consider about unlimited data SIM only contracts:

  • Most major UK networks offer unlimited data SIMs, typically available in both standard SIM and eSIM formats[1][5].
  • Vodafone provides three unlimited data tiers with different speed caps, all with no fair usage limits for UK use. Some Xtra Plans include global roaming with a 25GB cap abroad[1].
  • EE is reputed for speed and includes extras such as streaming service subscriptions with certain plans[1].
  • O2 offers unlimited data with additional perks (e.g., Apple Music, Disney+, Audible) and free roaming in up to 75 international destinations—but enforces a fair usage policy, such as investigation if you exceed 650GB twice in six months or routinely tether many devices[1].
  • Even advertised “unlimited” SIMs may come with constraints like speed throttling or tethering restrictions, so always check the terms if you plan heavy use or frequent tethering[2].
  • Some plans set “fair use” limitations for international roaming—Vodafone, for example, caps roaming at 25GB per month[2].
  • Prices can vary: budget networks like VOXI and Smarty often offer the cheapest unlimited SIM only deals, sometimes starting as low as £10 per month[2][3].
  • SIM only contracts almost always work out cheaper than traditional pay monthly phone contracts since you aren’t paying for a handset[4][6].
  • Many providers offer flexible 30-day contracts (ideal if you do not want to commit long-term), as well as discounted rates for committing to 12 or 24 months[1][2][6].

Example current providers and features:

  • Vodafone: Three speeds of unlimited data, no fair usage in the UK, 25GB cap abroad, choice of contract lengths[1][5].
  • EE: Fast unlimited plans with streaming perks and choice of contract length[1].
  • O2: Unlimited data, entertainment bonuses, variable global roaming, fair use policy applies[1].
  • VOXI: Unlimited social/data plans, rolling 30-day contracts, 5G access[3].
  • iD Mobile: Budget-friendly options, fair usage review for roaming above 30GB, no annual price rises[6].

While unlimited data SIMs are great for heavy users—streaming, gaming, tethering, frequent travel—lighter users might save money with a high-data cap plan (e.g., 100GB/month), as only a small proportion of users actually use more than 10GB monthly in practice[2].
