Is my phone eSIM compatible?

Pick your phone from 231 UK market devices across 12 brands and get two separate answers: does the phone support eSIM at all, and is it supported on the ONSIM network? Every verdict is verified against the manufacturer and at least one UK carrier list, with regional caveats spelled out.

What is an eSIM?

An eSIM (embedded SIM) is a SIM built into your phone at the factory. Instead of pushing a piece of plastic into a tray, you download your network profile onto the chip, usually by scanning a QR code. The number, the plan and the network are exactly the same as on a physical SIM; only the delivery changes. Most phones with eSIM also keep the physical tray, so you can run two lines at once, for example a personal mobile number and a business landline number on the same handset.

The *#06# check, explained

Compatibility lists (including ours) describe models. The *#06# test checks your exact unit, which is why we show it on every result. Open the dialler, type *#06#, and the phone displays its identity numbers. If an EID appears (a 32 digit number, listed alongside the IMEI), the phone has eSIM hardware. No EID, no eSIM. You can see the same information under Settings > General > About on an iPhone, or Settings > About phone on Android.

This matters because regional variants differ: iPhones from mainland China mostly have no eSIM, many India market Android variants drop it, and grey imports are the single biggest cause of "my eSIM will not install" support tickets. Sixty seconds with the dialler settles it before you buy a plan.

eSIM vs physical SIM

Speed: an eSIM can be delivered by email and activated in minutes; a physical SIM travels by post. Dual SIM: eSIM is how most modern phones do a second line without a second tray. Switching phones: a physical SIM moves between phones in seconds, while an eSIM has to be reissued or transferred to the new device, which is the one real trade-off. Security: an eSIM cannot be popped out of a stolen phone. Functionally, calls, texts and data behave identically on both.

A landline number on your eSIM, live in minutes

We built this checker because we issue eSIMs every day. ONSIM Landline eSIM puts a real UK landline number (01, 02, 03 or 08) on an eSIM in your existing phone: the activation QR code is emailed instantly at checkout, no app, no VoIP, no waiting for the post. From £10/user/month + VAT with unlimited UK calls under fair use. It runs happily alongside your personal SIM on any dual SIM phone. One honest caveat, and it is the reason this tool answers two questions instead of one: the phone must be on the ONSIM supported device list, not just eSIM capable. If yours is not, a Virtual Landline (£5/mo + VAT) diverts a landline number to any phone on any network.

Frequently asked questions

About eSIM compatibility, the EID test and ONSIM

Is my phone eSIM compatible?

Most phones sold in the UK since 2019 or 2020 are: every iPhone from the XR and XS (2018) onward, every Pixel from the Pixel 3, Samsung Galaxy S and Z flagships from the S20 (2020), and a growing share of mid-range Android models. But there are famous traps, like the Samsung S20 FE and S21 FE, the Xiaomi 14 Ultra and most budget Moto G and Redmi phones, which have no eSIM at all. Use the checker above for a verdict on your exact model, or dial *#06# for a definitive answer on your exact unit.

How do I check if my phone supports eSIM?

The fastest way that works on any phone: open the dialler and dial *#06#. If an EID (a 32 digit number) is shown alongside the IMEI, the phone has eSIM hardware; if there is no EID, it does not. You can also look in Settings > General > About on an iPhone, or Settings > About phone on Android, and check for an EID entry. This test beats any compatibility list because it checks your exact unit, which matters for grey imports and regional variants.

What is an EID?

The EID (eSIM Identifier) is a unique 32 digit number that identifies the eSIM chip built into a phone, in the same way the IMEI identifies the phone itself. Only devices with eSIM hardware have one, which is why checking for an EID via *#06# or the settings menu is the definitive eSIM test. Networks use the EID to deliver an eSIM profile to the right device.

Do all new phones have eSIM?

No. Flagships almost all do, and some (like the iPhone Air, and all US model iPhones since the iPhone 14) are eSIM only. But plenty of current budget and mid-range Android phones are still physical SIM only, including most Samsung Galaxy A1x and A2x models, most Moto G models, most Redmi and POCO phones, and every Nothing phone before the Phone (3). Regional variants matter too: phones from mainland China, Hong Kong or India frequently lack eSIM even when the UK version has it.

Can I have two eSIMs on one phone?

Often, yes. iPhone 13 and later run two active eSIMs at once, as do Pixel 7 and later and recent Samsung flagships (S24 Ultra, S25 and S26 generations, 2025 foldables). Many other phones store several eSIM profiles but only keep one active at a time, alongside the physical SIM. The checker flags dual eSIM support per model, so you can run a personal line and a business line, such as an ONSIM landline number, side by side.

Does eSIM work with ONSIM?

Yes, on supported devices. ONSIM issues eSIMs instantly: the activation QR code is emailed at checkout and your UK landline number is typically live within minutes. The key caveat is that eSIM capability alone is not enough, because the phone must also be on the ONSIM supported device list (iPhone XR or later, Pixel 6 or later, listed Samsung models, recent Motorola devices). The checker answers both questions separately for every model.
