iPhone 7 Plus and eSIM: the answer, and the workaround

No, and the Plus badge changes nothing

The iPhone 7 Plus has no eSIM. There is no chip inside it to activate, so no iOS update, carrier setting or app can switch one on. An eSIM is soldered hardware — either the handset was built with one or it wasn't.

Apple first shipped eSIM in 2018, in the iPhone XR, XS and XS Max. The 7 Plus arrived in 2016. It missed the change by two model years, and there is no route back.

People search this separately from the plain iPhone 7, and the instinct behind that is reasonable: the Plus was the more expensive of the pair, so you would expect the extra money to have bought extra hardware. On this one point it did not. The 7 and the 7 Plus give the same answer.

A phone this old is a decision, not just a question

If you have landed here before a trip, you are really asking one of two things: what do I use abroad, or is it time to replace the handset?

Take them in order, because they have different answers. The travel problem is solved without spending anything on a new phone. The 7 Plus has a nano-SIM tray, and a tray is not a handicap — it is the thing the newest US iPhones no longer have.

The replacement question deserves more thought than "it has no eSIM" gives it. On our own numbers, a physical SIM bought at the destination is frequently the cheaper way to get data. Buy a new phone when the battery, the camera or the security updates make the case. Not for a chip whose main advantage is that you don't have to walk into a shop.

What you use instead

Three routes work on a 7 Plus, roughly in the order they tend to win:

A local prepaid SIM bought at your destination. Usually the lowest cost per gigabyte, sometimes by a wide margin, because you are buying from the network rather than from a reseller. The cost is twenty minutes of your first day. Our country guides set out what the local carriers actually charge.

A physical travel SIM bought before you go. Fewer of these exist than there used to be, since the market moved to eSIM, and they cost more per gigabyte than a local SIM. What you get for the difference is landing already connected.

Roaming on your existing plan. Occasionally fine, occasionally the most expensive mobile data you will ever buy. Read the per-day rate before you fly rather than after.

Two things to settle before you land

Is the handset unlocked? A 7 Plus bought on contract can still be locked to the carrier that sold it, and a locked phone rejects a local SIM. Any contract on a phone this old is almost certainly paid off, so the carrier should release it on request — but do that from home, not from an airport counter.

What ID does the country want? Some places sell prepaid SIMs off the shelf. Others require a passport and a registration form before the line activates. It changes what you should be carrying when you walk into the shop.

Ten seconds to prove it yourself

Dial *#06#. The screen lists the handset's identifiers. If an EID appears alongside the IMEI, there is eSIM hardware. On a 7 Plus there won't be — worth confirming with your own eyes before you buy a travel plan that cannot install.

If there are several old iPhones in the drawer and you are not certain which is which, our eSIM compatibility checker covers every model in one list.

If you do replace it

Everything from the iPhone XR onward has eSIM, and those models kept their SIM tray as well, so you would gain an option rather than trade one away. The handsets to think twice about are the iPhone 14 and later sold in the US: those have no tray at all, and on one of those, buying a local SIM on arrival stops being physically possible. If price is what is driving the upgrade, our cheapest eSIM comparison is worth reading first — it may show that the saving you were expecting isn't there.
