iPhone 11 Series

The iPhone 11 series — iPhone 11, 11 Pro, and 11 Pro Max — all support eSIM. Released in 2019, these models were among the first iPhones to widely popularize eSIM use. They retain a physical nano-SIM slot and support one active eSIM at a time (Dual eSIM is not supported on iPhone 11 models).

Key Takeaways

• All three iPhone 11 models support eSIM.
• Physical nano-SIM slot is present — not eSIM-only.
• One active eSIM at a time (not Dual eSIM like later models).
• Carrier unlock required for Roamix and other third-party eSIMs.

Does the iPhone 11 Have eSIM?

Yes. The iPhone 11, 11 Pro, and 11 Pro Max all support eSIM. These models support one active eSIM at a time, in addition to one physical nano-SIM card. Dual eSIM (two simultaneous active eSIMs) is not available on iPhone 11 — that feature came with iPhone 12.

iPhone 11 models can store up to 5 eSIM profiles and switch between them, but only one is active at any given time alongside the physical SIM.

iPhone 11 Models and eSIM Compatibility

How to Activate eSIM on iPhone 11

1. Open Settings.
2. Tap Cellular, then Add Cellular Plan.
3. Scan the QR code from your eSIM provider. Roamix emails the QR code within 60 seconds.
4. Name the plan (e.g., "Roamix Travel").
5. Choose which line handles cellular data — select the Roamix eSIM for data abroad.

Using Two Lines on iPhone 11

iPhone 11 supports one active eSIM alongside one physical SIM at the same time. A common travel setup:

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

Go to Settings → Cellular → Cellular Data to switch between lines for data.

iPhone 11 eSIM for International Travel

iPhone 11 works with Roamix on any unlocked device. Purchase a plan, scan the QR code, and connect when you arrive.

Unlock check: Settings → General → About → Carrier Lock. Contact your carrier if locked.

iPhone 11 eSIM Troubleshooting

"Add Cellular Plan" missing: Carrier lock is the most common cause. Check Settings → General → About → Carrier Lock. T-Mobile requires 40 days of continuous active service before it will unlock an iPhone 11. AT&T and Verizon can unlock immediately if the device is paid off.

iPhone 11 purchased in China: Chinese mainland models use dual nano-SIM and have no eSIM hardware. They cannot use eSIM under any circumstances — a hardware limitation, not a software one.

eSIM not connecting abroad: Set the Roamix line as data line at Settings → Cellular → Cellular Data. Enable Data Roaming for the Roamix line. Toggle Airplane Mode off/on.

Can only store a limited number of plans: iPhone 11 models store up to 5 eSIM profiles (not 8 like iPhone 12 and later). Delete unused profiles at Settings → Cellular → [plan] → Remove Cellular Plan before adding new ones.

Transfer eSIM from iPhone 11 to new phone: Most eSIM profiles cannot be transferred directly. Contact Roamix support to deactivate the old eSIM and issue a new QR code for your new device.
