SimOptions offers a Guernsey eSIM that includes a phone number and SMS capability. The Holiday Europe eSIM provides 50GB of data for 31 days at a price of $38.90 USD and covers Guernsey plus 35 other countries. Telephony is available with a phone number that has the dialing code +33, allowing inbound and outbound voice calls as well as inbound and outbound SMS.
The dialing code +33 indicates the number is from France rather than a local Guernsey number, so users can receive and make calls and send and receive SMS. For specific requirements or confirmation of details, users should contact SimOptions directly.
