📲 Enjoy the flexibility of Dual SIM & eSIM technology!

Short answer? Yes! If your phone supports dual SIM functionality, you can keep your primary SIM active for calls & SMS while Kolet eSIM handles all your data needs.

✅ No SIM swapping, no interruptions, just smooth, effortless coverage.


🔄 How dual SIM works

Your phone supports the following configurations:

Two physical SIM cards (on select devices)

One physical SIM + One eSIM

Two eSIMs (available on iPhone 13, 13 Pro, 13 Pro Max, and later models)


🌍 Why use Dual SIM/eSIM?

✔️ Stay Connected While Traveling

Use Kolet eSIM for data abroad while keeping your primary SIM active for calls & SMS. Just be sure to disable roaming on your primary SIM to avoid surprise charges, because no one likes that kind of plot twist.

📞 Manage Multiple Numbers on One Device: Perfect for those who juggle international numbers, whether for work, personal use, or just to keep your travel life separate from your real life (we get it).

🔒 Keep Your Physical SIM Safe: No need to remove or swap SIM cards, reducing the risk of loss or damage.

👔 Separate Business & Personal Calls: Use two distinct numbers on the same device, one for work and one for personal use.

💬 Receive text messages : Especially useful when you need to receive activation codes to log in to apps like your bank or Uber
