Simsima for United Kingdom FAQ
Does Simsima offer unlimited data eSIM for United Kingdom?
Simsima does not provide a true unlimited‑high‑speed data eSIM for the United Kingdom. The plans listed under the name “Unlimited” actually give customers 3 GB per day of high‑speed data and, once that daily threshold is met, the speed drops to 1000 kbps; the plans are not unlimited in the sense of offering high‑speed data without limits.
For travelers needing larger data volumes, Simsima offers fixed‑data plans such as the 100 GB 180‑day plan, the 50 GB 30‑day plan, or the 50 GB 90‑day plan. Choosing one of these fixed‑data options can be more cost effective for those who need a substantial amount of data but are not extreme heavy data users.
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 offers 39 single‑country data plans that cover the United Kingdom alone and an additional 26 multi‑country plans that include UK coverage. The provider’s plans vary in price from about $3.10 to $452.76 USD, and data allowances range from 500 MB up to 100 GB over validity periods of 3 to 365 days. Among the available plans, some provide a fixed data amount for the entire validity window, while others apply a daily data cap that resets each day, giving users the flexibility to manage usage on a day‑to‑day basis.
