> 73 of 215 countries make Android users type the mobile data APN in by hand — iPhone never does. See which ones, and the exact steps.

## The APN problem: why “connected” doesn’t mean you have data

Android hands the data APN to your phone's own carrier database. For a foreign or virtual operator that database is often empty. 73 of the 215 countries in Airalo's catalogue leave the field for you to fill, checked 3 September 2026. Nothing on the iPhone side asks for it. This guide runs the Android install end to end, including that one manual step.

You can buy well before the trip. On the network partner’s terms the QR code stays valid for up to a year after purchase (the exact date is on your order page and in the email), and the paid days start only when the eSIM first connects to a network abroad — so install at home, fly, switch it on.

An APN, an Access Point Name, tells your phone which gateway to use for mobile data. iOS bundles that value into the carrier profile and writes it in the moment your eSIM installs. Android leaves the field to your phone’s own carrier database. For a foreign or virtual operator, that database often has nothing to fill in. The field then sits blank until you type it yourself. Your phone still registers on the tower. It still shows signal bars and a “connected” label. It still passes no data at all.

Turkey is a working example. Airalo’s Turkey eSIM roams on Türk Telekom, and its Android APN value is `globaldata`, typed by hand. The same profile fills that value in automatically on iPhone (Airalo catalogue data, checked 12 August 2026). [The Turkey eSIM guide](/destinations/turkey/) covers the packages and network that value sits on top of. [The iPhone install steps run separately](/guides/install-esim-iphone/) — the automatic fill removes this entire problem on that platform.

## What are the steps to add the profile: QR code or activation code?

A QR code and an activation code install the identical profile on your phone — Airalo delivers both with every eSIM: a scannable QR image, and the same SM-DP+ address plus activation code as plain text underneath it. Which one you use comes down to your screen situation, not any difference in what lands on the device.

The add-profile screen sits in roughly the same place across manufacturers, worded differently by skin:

1. Open Settings, then Network & internet or Connections.
1. Tap SIM manager or Mobile network.
1. Tap Add eSIM or Add mobile plan.
1. For a QR install, point the camera at the code — scan it from a second device (a laptop screen, a printed copy, another phone), since your own phone can’t scan its own screen.
1. For a manual install, tap “Enter details manually” and type the SM-DP+ address and activation code exactly as given, with no added spaces.

**Install the profile at home on Wi-Fi, not at the gate.** An eSIM install needs a working connection to complete, and an airport gate doesn’t reliably have one. 202 of the 215 catalogue countries give you a 365-day install window from the date of purchase (Airalo catalogue data, checked 3 September 2026), so installing weeks ahead costs nothing on its own. What that early install then starts is a separate question, covered below.

## Labelling the line and choosing which SIM carries data

Rename the new line the moment it installs. Left on a default label, a menu that calls both your lines “SIM 1” and “SIM 2” gives you no way to tell them apart mid-trip. In your phone’s SIM manager, tap the new eSIM entry, tap its name field, and type something you’ll recognise: the destination, or “Travel data.”

Then set it, specifically, as the line that carries your data. Still in SIM manager, find the Mobile data setting and point it at the new eSIM rather than your home SIM. Calls and texts can stay routed to your home line. Only the data toggle needs to move, and it doesn’t move on its own when the profile installs.

## Turning on roaming for the travel line only

Roaming on Android is a per-line switch. The travel eSIM is the only line that needs it on. A home line left roaming beside it triggers the exact charge the eSIM was bought to avoid. Open the travel eSIM's own entry in SIM manager and toggle Data roaming there. The phone-wide switch is not the one that matters here.

Then check your home line’s entry and confirm its own roaming stays off. Turning off that line’s cellular data entirely, not just roaming, stops a background app from silently reconnecting to it. Do this once you land, not before. Most Airalo profiles activate on first use rather than at install, so nothing is gained by flipping roaming on while you’re still on a home network.

## What are the steps to type the APN in by hand?

Six fields show up on the Access Point Names screen — only two usually need anything typed.

1. Go to Settings, then Network & internet or Connections, then SIM manager or Mobile networks, then your travel eSIM’s own entry, then Access Point Names — sometimes tucked under an “Advanced” heading.
1. Tap the add button, usually a `+` in the top corner.
1. Type a Name — anything works, it’s just a label; “Travel APN” is fine.
1. Type the APN value itself into the APN field. For Turkey that value is `globaldata` (Airalo catalogue data, checked 12 August 2026), typed exactly as given, no capitals added, no trailing space.
1. Leave MMSC, MCC, MNC and the remaining fields on whatever your phone pre-fills — editing one without a reason from your confirmation email is what turns a correct entry into a broken one.
1. Save the entry, back out to the APN list, then tap the new entry again so the radio button or checkmark sits next to it, not the old default — an unselected entry does nothing.
1. Toggle airplane mode on and back off, or restart your phone, to force a fresh registration against the new setting.

## Which countries need a manual APN, and what to type

73 of 215 countries in Airalo’s catalogue sell at least one eSIM that needs a manual Android APN. 67 of those need it on every profile they sell. The remaining six split depending on which specific product you buy (Airalo catalogue data, checked 3 September 2026). The table below gives the value for a sample of well-travelled destinations.

| Destination | Android APN (type manually) | iPhone |
|---|---|---|
| Turkey | globaldata | Fills in automatically |
| United States | wbdata | Fills in automatically |
| Japan | wbdata | Fills in automatically |
| United Arab Emirates | globaldata | Fills in automatically |
| India | globaldata | Fills in automatically |
| Germany | globaldata/orange/orange.fr | Fills in automatically |
| Brazil | internet | Fills in automatically |
| Indonesia | globaldata | Fills in automatically |

Source: Airalo catalogue data, checked 3 September 2026. Six countries in the catalogue sell more than one Airalo profile that disagree on this — Guatemala, Israel, Nicaragua, Paraguay, Puerto Rico and the US Virgin Islands. Check the specific package you’re buying, not just the destination. Airalo’s own product page states “Automatic” or “Manual” for Android under each country’s setup details. Check it before you fly, not after you land with no signal.

## The three countries where the clock starts at install, not first use

Three countries in the catalogue break the install-early rule, checked 3 September 2026: Bosnia and Herzegovina, Suriname, and Mayotte. There a profile's day-count starts the moment it installs, before the phone has seen a tower. Bosnia and Herzegovina and Suriname run it across the board, on both operator records Airalo lists for each. Mayotte does not. Only one of its two Choungui records runs the installation clock, so the rule attaches to a tariff there. On Android that timing lands on top of the APN step, which lives inside the profile's own entry. Both jobs end up on the same day.

Egypt ran this same policy on 12 August 2026 — both of its Giza Mobile operator records read installation then. A fresh Partner API pull on 3 September 2026 shows both switched to first-usage; Airalo publishes no changelog explaining why.

Everywhere else in the catalogue — 212 of 215 countries — installing early costs you nothing. The countdown only starts once your phone actually reaches a tower on the destination network. An installed-but-unused profile just sits there. Bosnia and Herzegovina and Suriname invert that. Install a 7-day profile a week before departure, and it can run out before your plane even lands.

[Mayotte](/destinations/mayotte/) splits down the middle. Its six fixed-GB packages, 1 GB through 20 GB, activate on first use like the rest of the catalogue. Its five unlimited-day packages activate on installation instead (Airalo catalogue data, checked 3 September 2026). Same country, two different rules, decided by which product you buy.

The install-early advice earlier in this guide is wrong for these three. For Bosnia and Herzegovina, Suriname, and Mayotte’s unlimited tier, install on the day you arrive, or as close to it as your itinerary allows — not the week before. Egypt used to belong on this list too; as of 3 September 2026 it doesn’t, so install it whenever suits your trip.

## Still no data? What are the next troubleshooting steps?

Five checks cover nearly every “installed but no data” case. Work through them in this order:

1. Confirm your travel eSIM, not the physical SIM, is still selected for mobile data in SIM manager — a restart can silently reset that choice back to SIM 1.
1. Reopen Access Point Names and confirm the new entry carries the selected mark, not just a place in the list. Adding an APN and selecting it are two separate actions.
1. Check data roaming is switched on for that specific line — a fresh install sometimes leaves it off by default even with the right data SIM set.
1. Toggle airplane mode on, wait ten seconds, then off. This forces your phone to re-register against the new APN and roaming settings, instead of reusing a cached, failed session.
1. Check the profile’s own status reads “Active,” not just “Installed.” Some Android builds separate the two, and a profile that never activated on the carrier’s side carries no data, no matter how correctly you typed the APN.

If none of that clears it, check the plan itself. A fixed-day package that has already ended, or a trip that has moved past its install window, won’t come back with a restart.

## FAQ

## Before you land: the checklist

Here’s how to install an eSIM on Android correctly. One pass, compressed, before you fly.

- Check whether your destination needs a manual Android APN before flying — 73 of 215 catalogue countries do (Airalo catalogue data, checked 3 September 2026).
- Install the profile at home on Wi-Fi; 202 of the 215 catalogue countries allow it up to 365 days before your trip.
- Label the new eSIM line the moment it installs.
- Set the travel eSIM, not your home line, as the data SIM before landing.
- Turn on data roaming for the travel line only, and turn off cellular data on your home line.
- Type the APN by hand if your destination needs one, save it, then select it as the active entry.
- Bosnia and Herzegovina, Suriname, and Mayotte’s unlimited tier start the clock at installation — install those close to arrival, not days ahead. [Egypt](/destinations/egypt/) doesn’t anymore, checked 3 September 2026 — install it whenever suits your trip.

## Sources and freshness

*Counted directly from Airalo’s own catalogue data — 215 countries and 368 operator records, recounted 3 September 2026. The Android APN field is set to “manual” on at least one product in 73 countries, and on every product in 67. Install windows run 365 days in 202 countries, 90 days in Israel, and are unpublished in 12.*

*The activation figure moved between our two checks, and both readings belong on the page. On 12 August 2026 exactly four countries ran the clock from installation rather than first use: Egypt, Bosnia and Herzegovina, Suriname, and Mayotte. On the 3 September 2026 Partner API pull, against a 215-country catalogue, only three do — Bosnia and Herzegovina, Suriname, and Mayotte — because both of Egypt’s Giza Mobile records had switched to first-usage by then. Airalo publishes no changelog, so we state the change and not a cause for it. Airalo updates its catalogue without a fixed schedule. Recheck a specific destination’s own setup page if it’s been more than a few months since this date.*

## FAQ

Why does my Android phone show "connected" but no internet after installing an eSIM?
Check the APN first. Your phone can register on the tower and show a signal with no Access Point Name set. Android, unlike iPhone, usually needs that value typed in by hand for a foreign network. Type it into the SIM's Access Point Names screen, save it, then select it as active.

Do I always need to enter the APN manually on Android?
No — only where the operator's configuration doesn't cover your device automatically. 73 of Airalo's 215 catalogue countries need it typed in; the rest fill in automatically (Airalo catalogue data, checked 3 September 2026). Check the destination's own product page before you fly.

How do I find the APN value for my destination?
Airalo lists it on each country's own eSIM setup page, next to "Android APN Settings," and again in your install confirmation email. For Turkey specifically it's `globaldata` (Airalo catalogue data, checked 12 August 2026).

Can I install the eSIM before I travel?
Yes, almost everywhere. Install windows run 365 days from purchase in 202 of 215 countries in Airalo's catalogue (checked 3 September 2026). The usage clock itself doesn't start until first connection in 212 of 215 countries, checked 3 September 2026 — Bosnia and Herzegovina, Suriname, and Mayotte's unlimited tier are the exception. Egypt carried that same exception on 12 August 2026 but had moved to first-usage by 3 September; install it anytime now.

Which SIM should carry data while I'm travelling?
Your travel eSIM, set explicitly in SIM manager under Mobile data, with your home line's own cellular data turned off. That stops a stray app pulling data over your home line's roaming connection while the travel eSIM handles your actual browsing.

Can I install eSIM by myself?
Yes — the entire install runs from your own phone's Settings, with no operator counter, no shop visit and nobody else's help. Airalo delivers both installation credentials to you directly: a scannable QR image, and the same SM-DP+ address plus activation code as plain text. Two things you have to supply yourself — a working internet connection while the profile installs, and, in 73 of Airalo's 215 catalogue countries, the Android APN typed in by hand afterwards (Airalo catalogue data, checked 3 September 2026).
