Service level agreements in travel eSIM occupy an awkward space. You are accountable to your customer for an experience delivered over radio networks you have no control of, through a chain of agreements you are not party to, in countries you have never visited. When it fails, the customer holds you responsible, which is entirely reasonable because they bought from you.
This covers what can honestly be committed to and what cannot, what to negotiate for instead of speed guarantees, and why verification through testing is worth more than any clause you are likely to obtain.
The uncomfortable position you are in
- You are accountable for an experience delivered by networks you do not control.
- Your customer blames you, correctly, because they bought from you.
- Most reseller agreements contain no meaningful service commitment at all.
- What you can realistically get is visibility and named carriers, not guaranteed speeds.
- Verification through testing is worth more than any clause you could negotiate.
What your customer is measuring you against

This framing matters for how you set expectations. A customer switching from operator roaming is not comparing you against other eSIM providers; they are comparing you against the experience their home operator gave them abroad, which they were paying around $42 a trip for. If your product is materially worse, the saving does not compensate, and that is the standard your provider selection has to meet.
What can and cannot be committed to
| Layer | Can it be committed to? | What to ask for |
|---|---|---|
| Platform availability | Yes, reasonably | Uptime commitment for the API and dashboard, with a measurement definition |
| Profile issuance | Yes | Time from order to activation code available, and success rate |
| Provisioning success | Partly | Download success rate, excluding device-side causes |
| Network attach | Weakly | Named host carriers per market, contractual where possible |
| Speed and throughput | No, realistically | Indicative expectations only; treat guarantees with suspicion |
| Support response | Yes | Response and escalation times, by severity, in stated hours |
The rows that can be committed to are the ones worth negotiating hard on. A provider offering guaranteed speeds on a roaming profile is promising something they cannot control.
The split here is between things inside the supply chain and things outside it. Platform uptime, issuance times and support responsiveness are your provider’s own operations and can be measured and committed to. Radio performance in a foreign city is not, and any commitment on it is either heavily qualified or unreliable.
That is not a reason to accept nothing. It is a reason to concentrate negotiation on the measurable layers and to seek visibility rather than guarantees on the rest.
What to ask for instead
| Ask for | Why | Weak answer |
|---|---|---|
| Named host carriers per market | The only real predictor of customer experience | "Coverage in 200+ countries" |
| Whether carrier access is contractual | Best-effort access can change without notice | Silence, or "our partners handle that" |
| Steering behaviour | Decides which network your customer lands on | "It selects the best available network" |
| Fallback when a network is congested | Determines behaviour in the failure case | No answer |
| Notification of carrier changes | A rate improvement may change the carrier mix | No process |
| Incident communication | You need to know before your customers tell you | Status page only, no proactive contact |
The steering row is the one most resellers never raise. When several host networks are available, something decides which your customer attaches to, and logic optimised purely for cost can place them on a congested or poorly covered network where a better option existed. You cannot control it, but knowing how it is configured tells you a great deal about the experience you are reselling.
Verification beats contract language
How to verify rather than trust
- Test profiles in your top destinations before launch
- Check which network the profile actually attaches to
- Test at a border crossing if you sell regional plans
- Observe behaviour when the allowance is exhausted
- Re-test after any rate change or carrier update
- Track refund reasons by destination as a quality signal
Signals of a quality problem
- Refunds clustering in one country
- Support contacts mentioning slow speeds in a specific market
- A sudden improvement in your wholesale rate somewhere
- Profiles attaching to a different carrier than before
- Repeat customers avoiding one destination
- Reviews mentioning a country you thought was strong
The refund clustering signal is the most useful thing on that list and costs nothing to implement. Tagging refund reasons by destination turns your existing support workflow into a quality monitoring system. A country that suddenly starts producing refunds is telling you something about the network before any status page does.
How to approach it
Negotiate the layers that can be committed
Platform uptime, issuance time, provisioning success rate and support response are all measurable and reasonable to put in an agreement. Spend your negotiating effort there rather than pursuing speed guarantees nobody can honour.
Get carriers named per market, in writing
This is the single most useful commitment available, because it is the only thing that actually predicts your customer\'s experience. Ask whether the access is contractual or best-effort, since the answer changes what the naming is worth.
Define severity levels before you need them
A failed profile issuance for one customer and a country-wide attach failure are not the same incident. Agree what counts as critical, and what response each level gets, while nothing is on fire.
Test before launch and after every change
Real profiles in your main destinations, checking attach time, which network, border behaviour and depletion handling. A cost improvement that arrives with a quieter carrier change is exactly what post-change testing catches.
Instrument your own quality signals
Refund reasons and support contacts tagged by destination will tell you about a degradation before your provider does. Treat a cluster in one country as a network signal rather than a coincidence.
Set your own customer commitment conservatively
Whatever you promise your customers, you have to deliver on infrastructure you do not control. Promise responsiveness and resolution, which you own, rather than speeds and coverage, which you do not.
Step six is about protecting yourself from your own marketing. It is tempting to promise reliable high-speed coverage because competitors do, but you are underwriting that promise with infrastructure you do not control. Committing to fast support, honest information and a straightforward reissue or refund is a promise you can actually keep, and it holds up better when a network has a bad day.
