Singapore → Bali → Uruguay is a useful stress test for the phrase “one eSIM for the world.” It separates two things that are often blurred together: keeping one profile installed and buying one package that covers every stop.
You can keep an eSIM profile on the phone after the first package ends. The next package can be added only when the provider confirms it for that profile’s ICCID. If Uruguay is not in the compatible list, the wording on a landing page cannot make it work. You will need another profile or a global package selected before departure.
Three sensible ways to build the trip
One global package
This is the lowest-friction option. Before leaving, choose a plan whose coverage explicitly includes Singapore, Indonesia and Uruguay.
It means one purchase, one installed profile and fewer settings to manage. The trade-off is price: a global plan may cost more than local packages, and network partners can differ by country. Read the coverage list for the exact package. “Global” is a category, not proof that every destination is included.
A regional Asia package, then Uruguay
Singapore and Indonesia may fit one Asia regional plan. That can make sense for the first part of the route, particularly when Bali is the longer stay.
Before the South America flight, open the installed profile and request its renewal options. If the provider returns Uruguay or a suitable global add-on for that ICCID, add it. If not, create a separate Uruguay profile.
A local plan at each stop
Local plans can be cheaper when each stay is long or data-heavy. The cost is operational: more orders, more profiles and more careful line switching.
Supported iPhones can store multiple eSIMs and let you choose which lines are active. The exact number of active lines depends on the model. Having two profiles on the device does not automatically mean deleting and rescanning them every time you cross a border.
Plan the route before comparing prices
Write down the trip in plain terms:
| Stop | Days | Main use | Hotspot |
|---|---|---|---|
| Singapore | 3 | maps, rides and tickets | no |
| Bali | 14 | navigation, social media and work | yes |
| Uruguay | 7 | maps, calls and email | no |
Then:
- Estimate data for each leg.
- Compare one global plan with Asia regional plus Uruguay.
- Check the activation rule for every package.
- Confirm whether tethering is allowed.
- Save the QR and manual setup details somewhere private.
The cheapest single card is not necessarily the cheapest complete route. Three small plans can leave unused balances and require more setup at inconvenient times.
How renewal works in PROM eSIM
Open the eSIM profile in your account and choose “Renewal options.” The server sends the ICCID to the provider and displays only the packages returned as compatible.
That check matters. Matching country names do not prove that a package can be attached to a particular profile. Compatibility is checked again before an order is created.
After a successful top-up, there is no new QR to install. The package is applied to the existing ICCID, and its usage state updates after the provider processes it.
When a new profile is the right answer
Use a new profile when:
- the provider returns no suitable package for the ICCID;
- the current profile was deleted and cannot be reinstalled;
- the desired plan belongs to an incompatible product line;
- the regional plan does not include the next destination.
This is normal technical behavior. A clear prompt to buy a new profile is safer than accepting payment for a package that cannot be attached.
Mistakes to avoid
- Do not delete a profile merely because its data ran out.
- Never post a QR code, LPA activation code or full ICCID in a public chat.
- Do not assume an “Asia” plan contains every Asian destination.
- Do not install early until you know what starts the validity clock.
- Do not leave cellular data on the primary SIM when its roaming is expensive.
The practical choice for this route
First compare an Asia regional plan with separate Singapore and Indonesia plans. For Uruguay, check both a global package and the renewal options of the installed profile.
If one global package lists all three destinations and has the right allowance, it gives the cleanest experience. Otherwise, an Asia profile plus a separate Uruguay eSIM is a reasonable compromise. The goal is not to preserve one QR at any cost. The goal is predictable data service at every stop.
