How to Install a Thailand eSIM on Google Pixel
Add a Thailand eSIM to your Pixel before departure: the Settings path, the per-SIM roaming switch, and an honest note on coverage beyond the tourist coast.
Updated August 24, 2026
Three things to know before you start
It connects only at your destination
Install at home, but expect “No Service” or “Activating…” until you land — that is normal. The plan wakes up when the line first finds a network at your destination.
Your QR code works exactly once
Seeing “invalid QR” after a scan almost always means the eSIM is already on your phone. Don’t rescan — open your SIM list and just switch the line on.
No internet after landing? Check Data Roaming
Turn the travel line on, set it as your mobile data line, and switch Data Roaming ON for it. This one toggle causes most “it doesn’t work” messages.
Installation steps
-
Step 1
Buy the plan in the Thailand eSIM app
Choose your plan and pay. The QR code and manual activation details are filed under the order and stay there, so you can come back if the first install does not take.
-
Step 2
Install at home, on Wi-Fi
A profile download needs a real connection. Doing it before departure loses you nothing, because the plan begins counting at its first connection to a Thai network rather than at purchase.
-
Step 3
Open Settings, then Network & internet
Settings Network & internet SIMs
Pixels run close to stock Android, so the path is short and has held steady across recent releases. If your build words it differently, type SIM into the Settings search box.
-
Step 4
Tap SIMs, or the plus icon beside it
Network & internet SIMs
With a physical SIM in use the entry reads SIMs with a small plus next to it. On a Pixel carrying no SIM you may instead see a direct invitation to add one. Both reach the same screen.
-
Step 5
Pick Download a SIM instead, then scan
SIMs Download a SIM instead
Android first offers to look for a carrier plan; skip that and choose Download a SIM instead, Google's wording for the option that accepts a provider QR code. Hold the Pixel over the code on another screen, or tap Need help for manual entry and copy the SM-DP+ address and activation code.
-
Step 6
Name the line, then switch it off
The Pixel downloads the profile and asks you to confirm. Label it Thailand so the dual-SIM screens make sense after a red-eye, keep your home SIM as the default for calls, and disable the new line until you arrive.
-
Step 7
After landing, enable it and make it the data SIM
SIMs Thailand
Open Settings, Network & internet, SIMs, select the Thailand line and switch it on, then set Mobile data to that line. Your usual number stays active on its own SIM for calls and texts.
-
Step 8
Turn Roaming on for the Thailand line only
SIMs Thailand Roaming
With the Thailand line open, switch Roaming on. Android keeps this toggle per SIM, which is exactly what you want here: it grants this line permission to attach to a visited network and adds nothing to a prepaid Thailand plan. Confirm your home SIM still has its roaming switch off.
Nothing about a Pixel makes this hard. The friction in a Thailand trip is elsewhere: in what your own carrier charges for the out-of-region band, one of the priciest rows on the sheet for most of the world, and in the half hour after landing when the arrivals hall is a choice between a Wi-Fi login page that will not load and a SIM counter queue moving at the speed of everyone else’s paperwork. Thailand runs those counters better than most countries; a queue at midnight after eleven hours in the air is still a queue.
An eSIM makes this a Tuesday-evening chore at home rather than an airport scramble. Buy the plan inside the Thailand eSIM app, let the line install over your own Wi-Fi, keep it switched off, and land with nothing left to do but flip one toggle. Installing early costs nothing, since the plan only starts counting from its first connection to a Thai network, never from the moment you paid. Full pricing is on the pricing page, and anything else we get asked lives on the FAQ.
On a Pixel, the menu path runs Settings into Network & internet, into SIMs, landing on Download a SIM instead. Two details deserve a second look. Google buries the option one screen behind an offer to search for carrier plans, and the label — Download a SIM instead — reads like a fallback when it is actually the exact button you need. The Roaming toggle, meanwhile, is set per SIM on a Pixel, so leaving it on for the travel line while it stays off on your home line is precisely the setup you want abroad. Other handsets get their own pages: iPhone, Samsung, or general Android if neither fits.
Two things we are not going to gloss over. First, this is a data-only plan, which means no Thai phone number comes with it. Most trips do not notice — messaging apps and internet calls handle everything — but a longer stay can, since a Thai bank account or certain local sign-ups want a number a Thai network can text, and there is no way around that on a data line. Your own number carries on working on your own SIM regardless. Second, Thai coverage follows population density: excellent across the cities, the towns and the main islands, thin in the northern mountains, inside the larger national parks, and out at sea between island crossings. Swapping SIMs does not move a single tower. Load offline maps before a ferry or a mountain road and you will hardly notice the gap; head out expecting full bars everywhere and you will.
Troubleshooting
Which Pixels take an eSIM?
Pixel 3 and everything after it, broadly, with regional exceptions — a handful of variants sold into particular markets shipped without the hardware. Rather than trust a list, dial *#06# on the phone you are holding: an EID beside the IMEI means the hardware is there.
Do I get a Thai phone number with the plan?
No. This is a data-only plan, so no Thai number comes with it and none can be attached. Your own number stays on your own SIM and remains reachable. On a holiday that is rarely felt — messaging and internet calls cover the trip — but a Thai bank account or any service that must text a Thai number needs a local SIM instead.
How good is coverage away from the cities?
Strong in the towns, along both coasts and on the well-travelled islands. Genuinely patchy in the mountains of the far north, inside the larger national parks, on remote corners of small islands and at sea between them. That is where the towers are, and no eSIM or local SIM alters it. If the trip includes a ferry or a mountain road, download offline maps in the last town with signal.
I cannot find Download a SIM instead.
Make sure you are in Settings, Network & internet, SIMs and not inside a carrier app. If the option really is absent while *#06# does show an EID, the Pixel is probably carrier-locked — operator handsets sometimes restrict which profiles they accept. That is a much easier phone call to make before you fly.
I have landed and the eSIM has no signal.
Check in order that the line is enabled under SIMs, selected for mobile data, and has Roaming on. Then toggle Airplane mode to force a fresh search. If it stays blank, open the line's network settings, switch off automatic selection, pick a network by hand, and put selection back to automatic once it registers.
Can I share the connection with a laptop?
Yes, hotspot is included. Turn it on under Network & internet, Hotspot & tethering. It is the practical answer for a guesthouse whose Wi-Fi collapses every evening, and for working an afternoon from a café table.
The QR code says invalid, already used, or the install fails on a second try.
An activation code is single-use, so this error almost always means the first scan already worked and the eSIM is on the phone. Do not keep rescanning. Open the phone's SIM list (the cellular or SIM manager screen) or My eSIMs in the Thailand eSIM app: if the line is listed, the install is done — turn the line on, give it mobile data and enable Data Roaming instead of installing again.
Do I have to scan the QR code at all?
No. In the Thailand eSIM app, open My eSIMs, tap your plan and tap Install — the profile installs on the same phone with no camera involved. The QR route exists for installing from a second screen; both end in the identical profile, and the steps after the install are the same either way.
