SimplySIM

SimplySIM, 4G and 5G data eSIMs for international travel

SimplySIM is a data eSIM provider for travellers that sells prepaid plans with coverage in over 180 countries. Its catalogue is organised by destination and lets you choose from data plans ranging from 0.3 GB to 50 GB, with 15- and 30-day validity options, as well as unlimited plans for 7, 10 and 14 days. The company operates through its website, simplysim.co.uk, and offers instant activation: the eSIM is installed before the trip and avoids roaming charges.

Plans by country and popular destinations

The offering is structured into single-country eSIMs and regional eSIMs for those visiting multiple territories. Featured destinations include the United Kingdom, the United States, Spain, Morocco, Turkey, Tunisia, Thailand, Egypt, Japan, the United Arab Emirates, Greece and Brazil. The catalogue includes, for example, unlimited 7-day plans for the United Kingdom, Morocco, Tunisia, Thailand, the United States and Canada, with full speed capped at 1 GB per day. There are also 10- and 14-day plans for Turkey and a 10-day plan for Egypt, plus a 10 GB plan valid for 30 days for Turkey. Prices shown on the site range from £10.76 for the 10 GB/30-day Turkey plan to £25.99 for the unlimited 10-day Egypt plan, with seasonal discounts applied in several cases.

Roaming cost comparison

SimplySIM presents its offering as a cost-effective alternative to traditional roaming. According to data on its website, UK mobile networks charge between £5 and £11 per day for using your phone abroad, which can amount to as much as £77 per week. The company states that its international eSIMs can save up to 90% compared with those rates and offers a roaming cost comparison tool between operators.

Compatibility and how it works

The company provides users with a device compatibility checker and a travel data calculator to estimate usage based on destination and trip duration. The plans use 4G and 5G networks from local operators; in the case of the United Kingdom, coverage includes Vodafone, O2 and Three, while in Morocco it operates with Orange, in Tunisia with Ooredoo, in Thailand with AIS and TrueMove H, in the United States with T-Mobile and Verizon, and in Canada with Rogers Wireless.

Promotions and discounts

The site shows seasonal offers, such as a summer promotion with discounts on selected eSIMs and a special autumn offer. In addition, SimplySIM offers a 10% student discount, redeemable after verification of a university email address (such as .ac.uk or .edu). The code is single-use per student and cannot be combined with other promotions. The company also sells gift cards and runs an affiliate programme and an influencer programme.
