Quick fixes

The things people ask about most, with the exact steps. These cover almost everything.

No data / won't connect

  1. Turn on Data Roaming for the Num line: Settings → Cellular → your Num plan → Data Roaming. This is normal for a travel eSIM and does not add roaming charges.
  2. Set Num as your Cellular Data line: Settings → Cellular → Cellular Data → Num.
  3. Make sure you've arrived at your destination — most plans start when the eSIM first connects to a local network.
  4. Toggle Airplane mode off and on, or restart the phone.

Still nothing? Message us with your order reference and we'll reissue or refund.

Install your eSIM

  1. Open the Num app → My eSIMs → tap your plan to see the QR code and steps. It's also emailed to you.
  2. On the phone you'll travel with: Settings → Cellular → Add eSIM → Use QR Code.
  3. Install over Wi-Fi before you fly — then it's ready the moment you land.

Installing on the same phone? Tap the install link in the app and it sets up without a second device.

Top up or check data

  • See how much data is left in the app under My eSIMs.
  • Reloadable plans (marked in the app) can be topped up in-app — no reinstall, same eSIM.
  • If a plan isn't reloadable, just buy a fresh one; you can keep it installed for next time.

Refunds, receipts & billing

  • If an eSIM can't be issued after payment, it's refunded automatically.
  • Receipts: in-app purchases are billed by Apple and appear on your Apple receipt; card payments get an emailed receipt.
  • Anything else — a wrong plan, a double charge — message us with your order reference and we'll fix it.

Num VIP membership

  • If VIP didn't unlock after paying, open the app and tap Restore purchases (Profile → Membership).
  • Make sure you're signed in with the Apple ID you subscribed with.
  • Manage or cancel anytime in Settings → your name → Subscriptions on your iPhone.

Phone & number

  • Works on most iPhones from XR/XS onward, as long as the handset is carrier-unlocked.
  • You keep your own number — Num runs as a data line alongside your normal SIM.
  • Check your device →
