Simp Mobile gives you two eSIMs:
UK eSIM (your main SIM with data, calls, texts, and EU roaming)
To set this up, download the Simp Mobile app from the App Store or Google Play.
When you log in for the first time, the app will guide you through the setup wizard.
Just carefully follow the on-screen instructions step by step. If you’re unsure when your iPhone or Android shows its own install prompts, check the instructions shown in the app’s onboarding — they explain exactly what to tap.
💡 Tip: Make sure you’re on Wi-Fi during setup.
If you ever need to reinstall later: open the app → go to Manage (second icon from the right on the bottom menu) → eSIM Instructions.
Global Roaming eSIM (for data use outside the UK/EU)
Open the app → go to Manage (second icon from the right on the bottom menu).
Tap Add Global Roaming eSIM and follow the on-screen instructions.
This will install your separate roaming eSIM for worldwide use.
