The story
WorldSIM began in 2006 as a company set on making calls and data abroad cheaper for travellers. Its stated vision is one SIM that works worldwide at the rates of a local one. The head office is in London, and the team now works from several places around the world.
The range
The core of the shop is travel eSIMs and international SIM cards. Some plans are data only, which suits maps, messaging and browsing, while others add calls and texts. Its international SIMs come with a UK number and a US number, and the company says incoming calls cost nothing in many countries. Beyond SIMs, it sells portable Wi-Fi routers, virtual numbers and travel accessories such as smartwatches.
eSIM or SIM
An eSIM installs on a compatible phone, so you can set it up before you leave without waiting for anything in the post. A physical SIM card suits phones without eSIM support. Check your handset first, because the shop lists the two separately. A portable Wi-Fi router can be handier when a group needs to share one connection.
Activation
On eSIM plans, the validity period starts when the eSIM first connects to a supported network, not when you buy it. Some plans ask for identity verification before they work, so leave a little time before you fly. Top-ups can extend the life of a SIM, and the company says its SIMs and top-ups come with a long validity.
Delivery
Physical items are posted worldwide, with the delivery options and costs for your country shown at checkout. eSIMs are digital, so there is nothing to wait for. Customs charges abroad are down to the buyer, which is worth knowing before ordering a router for a trip.
Returns
Unused products in unopened packaging can be returned within the legal change-of-mind window. You need to ask WorldSIM for a return number first, then send the item back to the address it gives you. Its policy page covers the rest.

Does WorldSIM sell eSIMs?
Yes. It sells travel eSIMs as well as physical SIM cards, so you can install a plan on a compatible phone before you leave.
When does a WorldSIM eSIM start counting down?
The validity period starts when the eSIM first connects to a supported network, not on the day you buy it.

Some plans require identity verification before they can be used. Check the plan details and allow time before you travel.

Unused items in unopened packaging can be returned within the legal change-of-mind period. Ask WorldSIM for a return number before sending anything back.

Lebara
Lebara sells SIM-only mobile plans in the UK with free international minutes included, and it is worth a look if you want to ditch a contract and choose a plan by the month. The range is built around low monthly costs and a simple way to stay in touch with people abroad.
BambooSIM
BambooSIM sells data-only travel eSIMs, so there is no physical SIM to post or swap at the airport. The useful question is whether your phone supports eSIM and whether the destination you need is covered by a plan that fits your trip length.
Ecotalk
Ecotalk is a SIM-only mobile network that sends its profits towards nature restoration in Britain rather than to shareholders. It runs on a major UK network, and its plans are on rolling monthly terms. Here is what it offers, who it suits, and what to check before switching.
Lyca Mobile
Lyca Mobile is a mobile network operator that runs as a virtual network on top of other providers' infrastructure. It has been operating since 2006 and describes itself as a major provider of SIM-only plans with a focus on high data allowances. For UK shoppers comparing SIM-only deals, it is one of the established names worth checking.
Metrofone
Metrofone sells mobile phones in the UK and Northern Ireland, so the first decision is usually the handset itself. Before looking at any monthly figure, check the model, storage size and the network arrangement attached to it. Those three things shape what you actually pay across the agreement.
Mobiles.co.uk
Mobiles.co.uk is an online-only phone shop that has been trading since the mid-1990s. It sells handsets and mobile plans, so the real decision is usually between buying a phone outright and taking one on a contract with airtime. Knowing which of those you want before you browse will save time.
