eSIM plans in Guernsey: what to expect
The cheapest 5 GB plan valid 30 days costs $4.75 (€4.17), which works out to $0.95/GB (€0.83/GB). Across the 1554 fixed-volume plans we track in Guernsey, the median price per GB is $1.51/GB (€1.33/GB). For reference, the worldwide average price of 1 GB of mobile data is $2.59/GB.
For a short stay, a few gigabytes valid 7 days are usually enough. For a longer trip, aim for 5 to 10 GB over 30 days, or consider an unlimited plan or a daily-quota plan: in that case compare the price per day rather than the total price.
