eSIM Phone Check: Simple Steps for 2026
Step-by-step ways to see if your phone works with eSIM so you can confidently buy a travel plan from Airalo, Holafly, or Saily.
You found a great travel eSIM deal from Airalo or Holafly. But before you tap "buy," you need to answer one question: can my phone even use an eSIM? The good news is that checking takes less than two minutes, and you do not need to be a tech wizard. By 2026, most phones sold in the last five years already have eSIM built in. This guide shows you exactly how to confirm yours does, using nothing but your phone's settings or a quick dialer code.
The 10-second Settings Check
The fastest way to test eSIM support is to look for an "Add eSIM" option right in your phone's settings. If you see it, you are ready to install a travel eSIM from providers like Airalo, Holafly, Nomad, or Saily. The steps differ slightly between iPhone and Android, so here they are.
On iPhone
Open Settings > Cellular (or Mobile Data). Do you see "Add eSIM" or "Add Cellular Plan"? If yes, your iPhone supports eSIM. All iPhone models from the XR and XS (2018) onward include eSIM. In fact, if you bought an iPhone 14 or later in the US, it has no physical SIM slot at all, it is eSIM-only. In 2026, that design is common worldwide for new iPhones.
On Android
Go to Settings > Connections > SIM manager (or "Network & Internet" on some phones). Look for "Add eSIM" or "Add mobile plan." On Samsung Galaxy devices, you will spot a plus sign next to "eSIMs." Google Pixel phones show "Download a SIM instead?" If any of those appear, your Android phone is eSIM-capable. In 2026, even budget models from Samsung, Xiaomi, and OnePlus ship with eSIM, so the "Add eSIM" option is becoming the norm.
If Settings Don't Tell You: Try the Dialer Code
Sometimes a phone's software hides the eSIM option until you insert a profile. But you can still peek under the hood using a universal dialer code. Open your phone's dialer app and type *#06#. Do not press call, the information pops up automatically. You will see one or more IMEI numbers. If your phone supports eSIM, you will also see an EID number (a 32-digit code) or a second IMEI labeled "Digital SIM." No EID, no digital IMEI? Then your phone almost certainly lacks eSIM hardware. This test works on both iPhone and Android and takes five seconds.
Still Not Sure? Check Your Phone Model
If the settings and dialer code both come up empty, you can cross-check your phone model against the list of known eSIM devices. In 2026, the list is long, but here are the most common ones travelers carry:
- iPhone XR, XS, 11 series, SE (2nd gen and later), 12 series, 13 series, 14 series, 15 series, 16 series (all models).
- Samsung Galaxy S20 series and newer, Galaxy Z Flip 3 and newer, Galaxy Z Fold 2 and newer, A54, A55, and many recent A-series.
- Google Pixel 3 and later (all models, including the Pixel 8a and 9a).
- OnePlus 9 and later, Xiaomi 12T and later, Motorola Razr 2022 and later.
If your phone is on this list, eSIM will work. You can also ask your carrier, but keep in mind that some carriers disable eSIM on locked phones. If you bought your phone through a carrier instalment plan, the eSIM feature might be restricted until the phone is paid off and unlocked. However, even a carrier-locked phone often lets you add a travel eSIM data plan while keeping your home line active on the physical SIM, just test with the steps above.
Which eSIM Provider to Pick Once You're Ready
Once you know your phone is eSIM-ready, you are a few taps away from avoiding roaming fees. At NomadCue, we compare travel eSIMs from Airalo, Holafly, Nomad, Saily, aloSIM, and Ubigi (plus others like Yesim and Jetpac). In 2026, pricing is more competitive than ever. For a 1 GB Europe plan, Airalo starts at around $4.50. Nomad offers 3 GB for $8 across many regions. Holafly focuses on unlimited data, with plans from $6 per day, perfect if you stream video or use a lot of maps. Saily, from the team behind NordVPN, sells 1 GB for $3.99 in popular destinations. aloSIM gives you a free phone number for calls, and Ubigi often has 5G coverage. You do not need to pick one blindly, our site shows side-by-side prices and real user reviews so you can grab the best deal.
Common questions
Can I use an eSIM if my phone is carrier-locked?
It depends. Many locked phones still let you add a travel eSIM for data, but the carrier may block adding a second line. If you see "Add eSIM" in settings or an EID on the *#06# screen, the hardware works. You can test by trying to install a free trial eSIM from Ubigi or a low-cost plan from Airalo, both take minutes and won't harm anything if it fails. If it does not work, contact your carrier to ask if they allow travel eSIMs on locked devices.
Do I need a physical SIM slot to use eSIM?
No. On phones that are eSIM-only, like the US iPhone 14 or later, you simply activate the eSIM as your primary line. You can store multiple eSIM profiles and switch between them, though usually only one or two can be active at once. The physical slot is not required.
Will an eSIM work on my older phone from 2019?
Many 2019 phones do support eSIM, like the iPhone XR/XS and Galaxy S20 series. If your phone is older than 2018, it probably does not have the hardware. Run the dialer code check to be sure.
Bottom line
Checking eSIM compatibility takes seconds, and in 2026 you are very likely to have a phone that supports it. Open your settings, glance for "Add eSIM," or dial *#06#. Once you see that tiny EID or the add-plan button, you are good to go. Then head to NomadCue, compare plans from Airalo, Holafly, Nomad, Saily, and others, and pick the one that fits your trip. No more SIM card swaps or carrier roaming charges, just a few taps and you stay connected abroad.
