Simsima for United Kingdom FAQ
Does Simsima offer unlimited data eSIM for United Kingdom?
Simsima does not provide a genuinely unlimited data eSIM for the United Kingdom. Their plans that carry the “Unlimited” name actually allow 3 GB per day of high‑speed data and then throttle the connection to 1000 kbps once that limit is reached. Travelers who need more data without throttling can choose one of Simsima’s fixed‑data plans, such as the 50 GB plan that lasts 30 days for $31.49 USD or the 20 GB plan that lasts 30 days for $14.41 USD. These fixed plans often offer a more cost‑effective solution unless a user anticipates consuming well over the daily 3 GB quota.
Does Simsima offer United Kingdom eSIM with phone number and SMS?
Simsima does not provide United Kingdom eSIM plans that include a local phone number or SMS capability. The available plans are data‑only, so users cannot receive or make SMS or incoming calls through the eSIM. However, messaging and voice applications such as WhatsApp, Telegram, and iMessage can be used over the data connection for communication.
How many data plans does Simsima offer for United Kingdom?
Simsima lists 18 single‑country data plans that cover the United Kingdom only, along with 20 multi‑country plans that include the UK as part of a broader coverage area. The single‑country options have prices ranging from about $2.70 to $116 and offer data caps from 200 MB up to 50 GB. The multi‑country plans fall within a similar price and data range, and they include both fixed‑data‑cap options, which give a set amount that does not refresh, and a smaller number of daily‑data‑cap options, where the allowance resets each day.
