Why top up a UK number remotely?

Whether you're an expat keeping a British SIM active, sending credit to a family member back home, or a traveller who needs their UK number topped up before a trip, international mobile top-ups have become an everyday need.

Supported UK operators

Through our top-up network we support all major UK operators:

  • EE — the UK's largest network by coverage
  • O2 — popular for data-heavy plans
  • Vodafone — strong EU roaming options
  • Three — Go Roam included on many plans

Step-by-step: top up a UK number

  1. Create a free account or log in at MobileTopUP.
  2. Select United Kingdom (+44) from the country list.
  3. Enter the mobile number (10 digits, without the leading 0).
  4. We'll auto-detect the operator — confirm or change it.
  5. Pick an airtime amount or a data bundle.
  6. Review the total (one transparent fee) and pay securely.
  7. The credit lands on the recipient's SIM in seconds.

What denominations are available?

Amounts range from £5 to £30 airtime credit, as well as data packs (3 GB · 7 days, 15 GB · 30 days) and unlimited combo bundles for 30 days. The exact catalogue depends on the operator.

Tips

  • UK numbers use a 10-digit national format. Exclude the leading 0 when entering — the +44 prefix is added automatically.
  • Top-ups are instant but may take up to a few minutes during network peak times.
  • If a top-up fails, you are not charged.
