GlobaleSIM sells United Kingdom eSIMs that include a phone number and support for inbound calls and messages. The plans range in price from $3.50 USD for 1GB over 7 days to $16.00 USD for 20GB over 30 days, with validity spanning 7 days to 30 days. Each plan provides a phone number with dialing code +1, enabling inbound and outbound voice calls; SMS can be received but not sent. The numbers are not local UK numbers, as the +1 code is for the United States, yet they are usable within the United Kingdom network. Travelers should check the current terms directly with GlobaleSIM to confirm the availability and exact functionality needed.
