CocoRoam sells eSIM plans that give users a phone number and SMS service while traveling in Guernsey.
Plan prices start at $17.30 USD for a 20 GB data pack valid for 31 days, and they climb to $48.30 USD for the 25 GB data packs also valid for 30 days, with a 100 GB option at $43.10 USD for 31 days.
The included phone number uses the international dialing code +33 (for the Svalbard‐and‑Jan‑Mayen islands offers) or +44 (for all other plans) – it is not a local Guernsey number. All plans allow inbound voice calls; outbound voice calls are also supported. SMS inbound is available on every plan; outbound SMS is only available on the Svalbard‑related plans, which offer full inbound/outbound SMS capability. Users are advised to double‑check exact features with CocoRoam before purchasing.
