Why partners choose eSimity
Ship faster. Waste less margin.
Sandbox that mirrors production
Separate host and credentials. Same endpoints, mock responses, test orders, usage, and errors before you go live.
Unused data credited back
When a plan expires with data left, we credit the unused share of wholesale cost to your partner balance, automatically.
Instant provisioning
Create orders, deliver QR profiles, track usage, and top up, via REST with webhook events for your ops stack.
Sandbox
How sandbox works
Build and QA against a dedicated environment. No live charges, no risk to production inventory.
Sandbox host
sandboxapi.esimity.com
-
1
Get sandbox credentials
After approval you receive a sandbox API key and secret, always available for testing, separate from live keys.
-
2
Call the same API shape
Countries, plans, orders, usage, and balance endpoints match production. Responses use realistic mock data.
-
3
Exercise failure paths
Validate happy paths, edge cases, and error handling before flipping traffic to the live API.
-
4
Go live with confidence
Swap host and credentials. Keep your integration code; change environment, not architecture.
Unused-data credit
How unused data is credited back
Customers rarely use every megabyte. We don’t make you eat the leftover wholesale cost.
Plan runs its course
When the eSIM expires or is depleted, we compare allowance vs actual usage.
Unused share is measured
Remaining data is calculated as a percentage of the original allowance.
Wholesale is refunded proportionally
That ratio is applied to the creditable wholesale cost and returned to your partner balance in EUR.
Spend it on the next order
Credits land automatically, no ticket required. Use them for new provisioning right away.
First-time profiles exclude a small non-refundable profile fee; top-ups are credited on full wholesale. Credits apply to completed API partner purchases with tracked usage.
