How to Get an eSIM: The Complete Beginner Walkthrough
Here's how to get an eSIM, step by step: confirm your phone supports it, decide whether you need a local carrier eSIM or a travel eSIM, choose a plan, buy it online, and install it from a QR code in your phone settings — usually with no SIM tray and no store visit at all. This walkthrough covers the whole journey for first-timers, whether you're getting a local eSIM at home or a travel eSIM for an upcoming trip.
An eSIM is a digital SIM built into your phone's hardware. Instead of a physical card, a carrier or reseller sends you a small profile — usually as a QR code — that you scan to load a phone plan onto your device. Everything below assumes you're starting from zero, whether this is your first eSIM ever or just your first from a new provider.
How to Get an eSIM in 5 Steps
1. Check that your phone supports eSIM
Not every phone has eSIM hardware, and some region-locked models (certain China-market iPhones, for example) have the feature disabled even though the rest of the world's version supports it. Before you buy anything, check for yourself:
- iPhone: Settings → General → About → look for "Digital SIM," or check Settings → Cellular → Add eSIM.
- Android: Settings → Network & Internet → SIMs (wording varies by brand) and look for an "Add eSIM" or "Download a SIM instead" option.
- Quick universal check: dial
*#06#— if an EID number appears alongside your IMEI, your phone has eSIM hardware.
If you're not sure your specific model qualifies, our phone compatibility checklist walks through it device by device — we won't repeat that detail here, since this guide is about the full process, not any one step of it.
2. Decide what kind of eSIM you actually need
This is the step most beginners skip, and it's where "how to get an eSIM" splits into two different paths:
| You want to... | Get a | What that involves |
|---|---|---|
| Replace your everyday SIM at home | A local carrier eSIM | ID verification, possibly porting your existing number, a full voice/text/data plan, carrier account setup |
| Get mobile data for a trip abroad | A travel eSIM | No ID or porting, prepaid data (often data-only), instant online purchase, works alongside your existing SIM |
Most people searching for "how to get an eSIM" for the first time are actually trying to do one of these two things, and the process differs enough that it's worth being clear early. A local carrier eSIM ties you into that carrier's plans and billing. A travel eSIM — the kind Simnity sells — is simpler by design: you're buying a short-term data allowance for a specific country or region, not a full phone plan.
3. Choose a plan
Once you know which path you're on, pick the specifics:
- Coverage: a single country, a multi-country region, or global.
- Data amount: total gigabytes for the trip or billing period.
- Validity: how many days the plan stays active once you use it (or from purchase, depending on the provider).
- Data-only vs. data+voice/text: most travel eSIMs are data-only, which is enough if you rely on WhatsApp, iMessage, or calling apps instead of a traditional number.
4. Buy the eSIM online
This is the part beginners often expect to be complicated, and it isn't:
- Go to the provider's website or app.
- Select your destination country or region and data size.
- Pay — this is a normal online checkout, with no in-person ID check for travel eSIMs.
- Get a confirmation email with your QR code or a manual activation code.
You can do this before you travel, even while your current SIM is still your only active line. Nothing about buying an eSIM disrupts your existing service until you actually install and turn it on.
If your goal is simply data for an upcoming trip rather than a full local phone plan, Simnity sells prepaid travel eSIMs for destinations around the world, delivered digitally — you buy, get your QR code by email, and activate whenever you land. You can check current destinations and plans at simnity.com.
5. Receive your eSIM and install it
Your QR code or activation code typically arrives by email shortly after purchase. From there:
- iPhone/Android, QR method: open your camera or Settings' "Add eSIM" screen, scan the code, follow the prompts, and label the new line (e.g., "Travel").
- No camera access, or the code won't scan: most providers let you enter the activation details manually instead.
The exact taps differ by phone brand and OS version, so we cover the full click-by-click install process separately in how to install an eSIM. If the scan itself is the problem rather than the install steps, see what to do when an eSIM QR code won't scan — that's a narrower, more common snag than most beginner guides call out.
Common mistakes first-timers make
- Buying before checking compatibility. Confirm eSIM support first — travel eSIM purchases can be non-refundable once the QR code is issued.
- Installing too early. For travel eSIMs, it's usually fine to install before you fly, but don't turn on data roaming until you land, or you may burn validity days early — this depends on whether the provider activates plans on installation or on first use, so check before you go.
- Forgetting to enable data roaming on the new line. Installing the eSIM isn't enough; you also need to switch to it (or enable dual-SIM data) and turn on roaming for that specific line.
- Assuming an eSIM gives you a new phone number. Data-only travel eSIMs don't include a number — you'll still use your existing number or an app like WhatsApp for calls and texts.
Getting the eSIM installed is only half the job — if it's not working once you land, that's a separate troubleshooting problem, not a sign you did this walkthrough wrong.
FAQ
Do I need to visit a store to get an eSIM? No. Both local carrier eSIMs and travel eSIMs can typically be bought and delivered entirely online, though some carriers offer in-store setup as an alternative.
What if my phone doesn't support eSIM? Then you'll need a physical SIM instead — eSIM is a hardware feature that can't be added after the fact. Check your model against our device compatibility guide before buying.
Does getting an eSIM give me a new phone number? Only if you choose a plan that includes one. Most travel eSIMs are data-only and don't assign a phone number; local carrier eSIMs usually do.
Can I install an eSIM before I travel? Yes, in most cases — you can buy and install it in advance and simply activate data once you land. Confirm your specific provider's activation policy so you don't start the validity clock early.
Can I have an eSIM and a physical SIM active at the same time? Many modern phones support this, letting you keep your home SIM for calls and texts while using an eSIM for data abroad. Exact limits vary by device model, so check your phone's own specs if you plan to run more than two lines at once.
