Simsima for United Kingdom FAQ
Does Simsima offer unlimited data eSIM for United Kingdom?
Simsima does not provide a true unlimited data eSIM for the United Kingdom. The plans that include “Unlimited” in their name supply 3GB of high‑speed data per day for 7, 10 or 30 days; once the daily 3GB threshold is reached the speed is reduced to 1000 kbps.
Travelers who need larger data allowances can choose from Simsima’s fixed data plans, such as the 50GB 30‑day plan for $33.59 USD or the 50GB 90‑day plan for $105.13 USD, which offer substantial data limits without the speed throttling that follows the “Unlimited” plans.
Does Simsima offer United Kingdom eSIM with phone number and SMS?

If voice or texting is needed, it is typically handled through VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection; however, users should verify that these services are not blocked or restricted in the United Kingdom before relying on them.
