Monthly packages

Four ways UK SIM users typically split by usage

These tiers describe the shape of monthly SIM allowances available across the UK market — not a single fixed price. Call our advisors for the current options that match your tier.

  • Light data — email, maps, messaging apps
  • Good fit if you're mostly on Wi-Fi at home or work
  • No fixed 24-month contract required on many options
Tier 2

Allowances shown are illustrative tier bands, not a live quote. Real plan prices and data limits change frequently and vary by provider — call 0330 059 8761 to discuss which usage tier may fit your needs.

Why call instead of clicking through a form

A two-minute conversation beats a ten-field form

Online sign-up forms can't ask a follow-up question. Our advisors can — so if you say you stream music on your commute, they'll ask whether that's over Wi-Fi or mobile data before pointing you anywhere.

  • No account creation, no card details taken on this site
  • You describe your usage in your own words, no tick-boxes
  • Advisors will say plainly if a tier doesn't suit you
  • Independent of any single UK network operator

Common questions

Before you call

Is Alyan Geek Center a mobile network?

No. Alyan Geek Center, operated by SIGE (USA) INFORMATION TECHNOLOGY CO., LTD, is an independent comparison and advisory service. We don't sell airtime or issue SIM cards ourselves — our advisors talk you through the shape of the UK market and point you toward options that fit your usage.

Will I be asked for payment details on a call?

Our advisors do not take card payments over this line. Any purchase, if you choose to go ahead with a specific plan, happens directly with the relevant provider, never through this website.

How long does a typical call take?

Most calls run two to five minutes — enough time to describe how you use your phone and hear back a tier that matches, plus any follow-up questions you have.

What are your calling hours?

See our Contact page for current opening hours before you call.

Not sure which tier fits your usage?

That's exactly what the call is for. Describe an ordinary week for you and we'll talk through the closest matching options — no obligation.
