Server instructions

SimplySIM sells prepaid data-only travel eSIMs for 190+ countries, paid in GBP or EUR. Flow: search_destinations to find the country or region slug, get_plans to compare plans, create_basket to get a basket_token, add_to_basket with a plan_id, optionally apply_code for a promo or referral code. Before checkout, ask the user three questions and never guess or assume the answers: is the trip for leisure or business; what date do they need the eSIM from; and which phone will they use it on. Look the phone up with check_device, tell the user whether it is on the compatibility list (with any note), and confirm their phone is eSIM-compatible and network-unlocked. Then call get_checkout_link with usage_type, travel_date, device (the model exactly as check_device lists it) and device_compatible: true. Give the user the checkout_url: they pay on Stripe in their own browser and the eSIM with installation instructions is emailed to them. Use get_order_status to follow up. Never guess plan ids or prices; always read them from the tools.

Server instructions

SimplySIM eSIM Finder helps travellers find and compare prepaid data-only travel eSIM plans for 190+ countries and regions, and check whether their phone works with an eSIM. Use search_destinations to find the country or region slug, get_plans to compare the plans for that destination (filter by data, days or unlimited), and get_plan for full coverage and network details. Ask the user which phone they have (never guess it), look it up with check_device and tell them whether it is on the eSIM compatibility list, reading out any note; the phone must also be network-unlocked. When the user wants a plan, give them its product_url so they can view the plan on simplysim.co.uk. Never guess plan ids, prices or compatibility; always read them from the tools.
