iPhone 13 Series

The iPhone 13 series — iPhone 13 mini, 13, 13 Pro, and 13 Pro Max — all support eSIM. Unlike later iPhone 14 US models, the iPhone 13 keeps the physical nano-SIM tray, giving you the option to use both a physical SIM and an eSIM at the same time.

Key Takeaways

• All iPhone 13 models support eSIM.
• A physical nano-SIM slot is present — not eSIM-only.
• Dual eSIM: run 2 active eSIM lines simultaneously.
• Carrier unlock required for third-party eSIMs like Roamix.

Does the iPhone 13 Support eSIM?

Yes. Every iPhone 13 model supports eSIM. All four models — 13 mini, 13, 13 Pro, and 13 Pro Max — were released in 2021 with eSIM capability and retain the physical nano-SIM slot that later iPhone 14 US models removed.

This means you can run a physical SIM and an eSIM simultaneously on iPhone 13, giving you up to three lines: one physical SIM and two active eSIMs.

iPhone 13 Models and eSIM Compatibility

How to Activate eSIM on iPhone 13

1. Open Settings.
2. Tap Cellular, then Add Cellular Plan.
3. Scan the QR code from your eSIM provider. Roamix sends the QR code by email within 60 seconds.
4. Name the plan (e.g., "Roamix Travel").
5. Set the Roamix eSIM as your cellular data line.
6. Your physical SIM stays active for calls and texts if you prefer dual-line operation.

Using Two Lines on iPhone 13

iPhone 13 is particularly flexible for travelers because it retains both a physical SIM slot and Dual eSIM support. A common travel configuration:

• Physical SIM (home carrier): Calls and texts. Data Roaming off.
• Roamix eSIM: Primary data line. Data Roaming on.

Alternatively, if you have two eSIMs installed:

• eSIM 1 (home carrier eSIM): Calls and texts.
• eSIM 2 (Roamix travel eSIM): Data line.

Configure which line handles data at Settings → Cellular → Cellular Data.

iPhone 13 eSIM for International Travel

iPhone 13 works with Roamix on any unlocked device. Purchase a plan, scan the QR code, and your phone connects to a local network when you land.

iPhone 13 eSIM Troubleshooting

"Add Cellular Plan" missing: Carrier lock is almost always the cause. Check Settings → General → About → Carrier Lock. T-Mobile requires 40 days of active service. AT&T introduced same-day unlocking starting with the iPhone 13 generation for paid-off devices.

iPhone 13 purchased in China: Chinese mainland models are dual nano-SIM only — no eSIM hardware. The 13 mini was also the most commonly MVNO-locked variant due to its popularity on Boost and Mint Mobile — check Carrier Lock before purchasing an eSIM.

eSIM not showing after installation: Check Settings → Cellular and look for the plan. If listed but inactive, tap it and enable the line.

No service after installing eSIM: Go to Settings → Cellular → Cellular Data and confirm Roamix is selected. Enable Data Roaming for the Roamix line.

How to delete eSIM on iPhone 13: Settings → Cellular → tap the plan → Remove Cellular Plan. This is permanent — save your QR code before deleting if you want to reinstall later.
