SimOptions provides United Kingdom eSIM plans that include a phone number and voice capability. All of the UK‑covering plans carry a dialing code of +33, which is a French number, not a local United Kingdom number. Calls can be received and sent on every plan. SMS send and receive services are only available on the Holiday Europe eSIM plan, which costs $38.90 USD and is valid for 31 days. The other United Kingdom plans—Travel Basic+, My European eSIM 30GB, My European eSIM 60GB, and My European eSIM 120GB—range in price from $23.90 to $55.90 USD and are valid from 15 to 30 days, but they do not support SMS. Users should confirm the exact features they require directly with SimOptions.
