About WorldSIM

WorldSIM is a London-based telecoms company that sells prepaid SIM cards and eSIMs for international travel. The idea is to avoid roaming charges by using one SIM or eSIM across many countries, topping up credit online as you go rather than signing a contract. It has traded since 2006.

The main products are the International SIM Card and the International eSIM Pro, which cover calls, texts and data and come with a UK mobile number, with a US number available as a paid add-on. There is also eSIM Connect, a data-only eSIM sold by country or region, plus country-specific SIMs for the UK, USA, France and Qatar. Away from SIMs, the shop sells unlocked portable WiFi routers from ZTE, Huawei and TP-Link, travel accessories, smartwatches and phones.

Prices on the UK site are in pounds, and physical items are posted from the UK, with recorded UK delivery from £4. Customer support is advertised as available around the clock, including via WhatsApp. Airtime and SIM validity rules apply, so it is worth reading the plan details before you buy.

WorldSIM delivery and returns

Delivery	UK recorded delivery £4 (3-5 working days) or next day £7; free on orders over £100.
Returns	Unused items in unopened packaging can be returned within 14 days for a refund minus postage; products carry a 6-month warranty.
