Comet SIM eSIM Data Plans for United Kingdom

Comet SIM does not provide an unlimited‑data eSIM plan for the United Kingdom. The provider’s United Kingdom offerings are fixed data bundles, each with a set data cap and validity period. For instance, the 20 GB plan is priced at $19.90 USD and is valid for 30 days, while the 10 GB plan costs $12.90 USD for the same 30‑day validity. Fixed data plans can be more cost‑effective for most travelers, unless the user anticipates extremely heavy data usage that would require a different provider or a larger data bundle.

Comet SIM does not provide a United Kingdom eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered for the United Kingdom.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so travelers should verify that the apps they rely on are accessible in the United Kingdom before purchasing.

Comet SIM currently lists five single‑country data plans and ten multi‑country plans that can be used in the United Kingdom. The plans cover data caps from 1 GB up to 20 GB, with prices ranging from $3.90 to $119.90 and validity periods of 7 to 30 days. Some options provide a fixed amount of data for the whole validity period, while others reset the available data each day, offering a daily data cap. No other plan types are listed for this provider.
