About Fonehouse

Fonehouse is a UK mobile retailer that lists phone and SIM deals from across the major networks. Think of it as an aggregator, a single storefront rather than a network with its own masts. The signal behind any plan belongs to its underlying network. SIM-only plans start from a low monthly price a month. Compare the live Fonehouse deals below.

Quick facts

  • An aggregator that lists deals, not a mast-owning network
  • Pulls phone and SIM offers from the major networks together
  • Whatever you buy, the underlying network carries your signal
  • Useful for browsing several providers from one storefront
  • Move your number across with a PAC code

How Fonehouse works

Picture Fonehouse as a shelf stacked with offers from across the major networks, not a provider in its own right. You browse what is on that shelf and buy from Fonehouse, but the calls, texts and data on any plan travel over the underlying network's masts. So the deal carries the Fonehouse name at checkout, while the actual service is supplied by whichever network sits beneath it.

What you can get

Browsing Fonehouse turns up SIM-only tariffs as well as handset deals, gathered from the major networks. The upside of that breadth is straightforward comparison: you can put different allowances, lengths and prices next to each other in one go. Offers move around fast, though, so treat the live listings above as the truth on what is available today before you decide.

Plan types across networks

Because the offers originate from different networks, you will not see one tidy set of options. Some tariffs roll month to month, others run as longer commitments, and the allowances swing widely between them. Quoting one coverage figure would be wrong, since every tariff leans on its own network. Narrow down on cost and data first, then verify that the underlying network performs well in the spots you frequent.

Who Fonehouse suits

This works for anyone who would rather scan offers from across the major networks in a single sweep, and who is happy judging a plan on its merits instead of the badge selling it. If breadth of choice beats brand loyalty for you, the aggregator model fits. Bear in mind the coverage you inherit is the network's, so test that network's signal at your postcode before committing.

Pros

  • Offers from the major networks pulled into one storefront
  • Both SIM-only tariffs and handset deals on the shelf
  • Easy to line up allowances and prices side by side
  • No tie to any one provider's range

Cons

  • An aggregator, not a network, so your signal is the underlying network's
  • Tariffs differ widely between networks, so read each one's terms

Our verdict

Fonehouse earns its place if you want offers from across the major networks gathered in one storefront, provided you test the signal of the underlying network before you buy.
