The eSIM not provisioned error means the eSIM profile has downloaded onto your phone but the mobile network has not yet activated the line, so your phone holds an identity it is not allowed to use. It is an activation state on the network side, not a broken profile and not a damaged handset, and in most cases a restart or a few minutes of patience clears it.
This page explains what the message actually reports, what causes it on travel eSIMs specifically, and the fixes in the order that carries least risk. The same guidance covers the variants: eSIM 1 not provisioned, SIM 1 not provisioned, and SIM not provisioned MM#2.

What the error means
An eSIM profile has two halves. One half is the file on your phone, downloaded from the provider when you scanned the QR code. The other half is a record on the mobile network that says this identity belongs to a live subscription with data attached.
Not provisioned means the first half arrived and the second half did not. The phone can see a line, show its name in settings, and try to register, but the network rejects the registration because it has no active subscription record for that identity yet.
That distinction matters because it tells you where the fix lives. Nothing you do to the file on your phone changes the record on the network. Restarting helps because it forces a fresh registration attempt, not because it repairs anything locally.
The five things that cause it
In roughly descending order of how often they explain the error on a travel eSIM:
- The activation has not propagated yet. The commonest cause and the least alarming. Provisioning is usually instant but can lag by minutes during congestion.
- The plan has not started. Many plans begin on first connection in the destination, but some start on a fixed date. A line switched on before that date has no active subscription behind it.
- You are outside the plan’s coverage. A plan for one country will not provision on a network in another, which catches people during layovers. Check the plan’s country list, not the region name.
- The plan is finished. An expired validity period or exhausted data leaves the profile in place with nothing behind it, and some phones report that as not provisioned.
- The profile was installed on a second device, or reinstalled. Most eSIM profiles are single use. A profile downloaded twice can leave the network pointing at the wrong installation.
Note what is not on the list: a faulty phone, a damaged eSIM chip, or anything requiring a factory reset. None of those produce this error.
Fixes in order of risk
Work down this list and stop at the one that works. The order matters because the later steps are harder to undo.
- Restart the phone. Forces a fresh network registration and clears the majority of cases.
- Toggle aeroplane mode on, wait thirty seconds, off. A faster version of the same thing when a restart is inconvenient.
- Confirm the line is switched on and set for data. In cellular settings, check the travel line is enabled and selected as the data line, and that data roaming is on for it. Travel eSIMs connect as roaming partners, so roaming off means no service.
- Check the plan dates and the country. Has the start date arrived, is the country on the plan’s list, and is there data left. Our guide to checking data left on a travel eSIM covers how to read this.
- Select the network manually. Turn off automatic selection and pick a listed operator by hand, as described in fixing no signal abroad with network selection. If one operator refuses, try the next.
- Contact your provider. Give them the order reference and the exact error string. They can see whether the subscription is active on their side, which you cannot.
- Reinstall only if the provider tells you to and confirms they can reissue the profile.
Step seven sits last for a reason. Deleting an eSIM removes the only copy of a profile that is frequently single use, and the eSIM troubleshooting guide explains why deleting first turns a fifteen minute delay into a lost plan.
Why SIM 1 not provisioned names the wrong slot
On a dual SIM phone, the labels SIM 1 and SIM 2 describe positions, not technologies. Depending on the handset and the order lines were added, your eSIM can occupy the position the phone calls SIM 1, which is why Samsung and other Android devices often report SIM 1 not provisioned when the affected line is the travel eSIM.
Do not chase the number. Open your cellular or SIM manager settings, look at which named line shows no service, and apply the fixes to that one. If you are running your home line alongside a travel plan, our dual SIM travel setup guide covers how to label each line so this ambiguity stops happening.
The same message with an MM#2 suffix comes from the modem rather than the operating system. It carries no extra diagnostic value for a traveller and needs no different fix.
Error strings and what each one means
Phones report the same underlying state with different wording, which is why searching the exact string returns contradictory advice. They map onto three distinct situations.
| What your phone shows | What it means | First thing to try |
|---|---|---|
| eSIM not provisioned, eSIM 1 not provisioned | Profile installed, network has not activated the line | Restart, then check the plan start date |
| SIM 1 not provisioned, SIM not provisioned MM#2 | Same state, reported against a slot number rather than the eSIM by name | Identify which named line has no service, then treat as above |
| No service on the eSIM line only | Registration failed rather than provisioning | Switch on data roaming for that line, then select a network manually |
| Invalid SIM or SIM failure | The profile itself is missing or damaged | Contact the provider before deleting anything |
| Plan shows active but no data | Provisioned correctly, data routing is wrong | Set the eSIM as the data line and check the APN |
Only the last two rows describe a problem with the profile. The first three are all the network side catching up, and all three respond to the same sequence above.
When to stop and contact support
Three signals mean further self troubleshooting will not help.
- An hour has passed with the line switched on, in a covered country, after at least one restart.
- The provider’s own account page shows the plan as inactive or not yet started, which is a subscription question rather than a device one.
- A second device shows the same behaviour, which points at the subscription rather than the handset.
When you contact support, send three things: the exact error text, the country and city you are in, and the order reference. That set lets a provider check the activation record immediately instead of asking you to restart again.
If you are still setting up, installing the profile before departure over home Wi Fi removes most of the conditions that produce this error in the first place, as covered in how to install and activate an eSIM. Plans that activate cleanly on arrival are listed by country on the destinations index.
If you need a working plan today
If the plan behind the error has expired or run out, and the provider cannot revive it, the fastest route back online is a fresh plan rather than more troubleshooting.
Viasimo sells prepaid travel eSIMs for more than 190 destinations, delivered as a QR code by email in minutes. It installs from your phone’s own settings with no app to download, it is a one off purchase with nothing to renew or cancel, and the coverage and price are shown before you pay. Because the plan is data only, your home number stays live on your existing line throughout.
Pick the country you are standing in: USA, Europe, Japan, or the full destinations index. If you are still on Wi Fi, install it now and switch the line on when you are ready.
If you would rather start from the plans themselves, the eSIM plan picker asks for your destination and your trip length and shows you what fits.
