iPhone 13 Pro and eSIM: what to verify on a used handset

Compatibility is the easy part

Yes, the iPhone 13 Pro has eSIM. It has a SIM tray too. Every 13 Pro sold anywhere in the world has both, so unlike the iPhone 14 and later there is no regional variation to untangle — the market it was sold in does not change the answer.

Which means the compatibility question is settled and the real question is different. A 13 Pro is a 2021 flagship, and in 2026 the great majority change hands refurbished, ex-corporate or ex-contract. Every failure we would expect on one of these is inherited, not built in.

Four checks before you trust it abroad

1. Confirm the eSIM hardware responds. Dial *#06#. You should see an EID listed next to the IMEI. This takes five seconds and rules out the one thing that would be unfixable.

2. Check for a carrier lock. This is the big one on an ex-contract handset. A locked phone has working eSIM hardware and will still reject a third-party profile, usually with an unhelpful error at the last step of installation. The seller's word is not evidence. Ask the carrier the phone was sold through, or test it with any SIM or eSIM from a different network before you book anything around it.

3. Clear the previous owner's profiles. Look under mobile data settings for eSIM entries that are not yours. A stale profile from a network you have never used takes up a slot and creates confusion about which line is doing what. Delete it.

4. Confirm it is properly signed out. A device still tied to someone else's Apple account is a separate problem from eSIM, but it surfaces at the same moment — the first time you try to set something up abroad.

Why the tray is still an asset on this one

The 13 Pro is the generation immediately before Apple removed the SIM tray from US iPhones. On a 14 or later bought in the States, a local prepaid SIM is physically impossible. On your phone it isn't.

That matters most for two kinds of trip: long stays, where a local contract-free plan bought in a city shop can beat a visitor eSIM outright, and destinations where you need a local phone number rather than just local data — for delivery apps, bookings and SMS verification codes. Data-only travel eSIMs frequently come without a number at all. The tray gives you a route to one.

Whether that route is worth taking depends entirely on the country's prepaid market and its ID rules, which is what the country guides cover.

The setup that works for most trips

Home SIM stays in the tray, live for calls and texts. Travel eSIM carries data. Data roaming explicitly off for the home line, because on dual SIM it is easy to leave one background service quietly roaming on the expensive line.

Install the eSIM before you leave, over wi-fi you trust. Installation needs a working connection, and if it fails at an airport you want to be somewhere you can email the provider rather than somewhere you can't.

If a check fails

A leftover profile you can delete yourself. A carrier lock takes days rather than minutes and has to go through the network the phone was sold on. Neither is a reason to write the handset off — a 13 Pro that passes all four checks is a perfectly current travel phone, and its eSIM will behave exactly like one in a brand-new iPhone.
