Why doesn't PlayStation Remote Play work over my mobile data?

PlayStation Remote Play may not work over your mobile data due to several possible reasons related to network and data settings:

  • Data restrictions: If your Mozillion plan is data-only or has limited data allowance, once you run out of data, services like Remote Play won’t work.
  • Network coverage: Remote Play requires a stable and fast internet connection. If your mobile data connection is weak or unstable, the service may fail.
  • Network settings: Some mobile networks or devices may block or limit certain types of traffic needed for Remote Play.
  • VoLTE and WiFi Calling: If you are roaming and these features are enabled but not supported by the local network, it might affect connectivity.
Did I order an eSIM or a physical SIM?

To find out if you ordered an eSIM or a physical SIM card with Mozillion, please check the confirmation email you received after your purchase:

  • If you received a QR code via email, you ordered an eSIM. You will need to scan this QR code with your phone to install and activate your eSIM.
  • If you received a physical SIM card by post, you ordered a physical SIM card. You can install it by popping out the correct size (standard, micro, or nano) and inserting it into your phone.

If you are still unsure, you can also log in to your Mozillion Dashboard to view your order details.

What number do I dial to access my voicemail messages?

You can access your voicemail messages by calling your own Mozillion mobile number from your phone. If you have voicemail set up, your phone will automatically redirect you to your voicemail service.

If you need to enable or manage voicemail, you can do this through your Mozillion Dashboard by logging in and adjusting your voicemail settings in the Manage plans section.

I have two contracts - which SIM belongs to which?

To identify which SIM card is which in your phone, you can follow these steps:

  • Check your phone’s SIM card tray: Most phones have a SIM tray that shows the slot numbers (e.g., SIM 1, SIM 2). You can remove the tray using the SIM removal tool and see which SIM card is in which slot.
  • Look at your phone’s settings:
    • On Android, go to Settings > Network & Internet > SIM cards or Mobile Network. Here, you can see the names or numbers assigned to each SIM slot.
    • On iPhone, go to Settings > Cellular or Mobile Data. You will see labels for each SIM or eSIM installed.
  • Rename your SIMs: Many phones allow you to rename each SIM in the settings to something recognisable (e.g., “Work” or “Personal”) to help you distinguish them.
  • Test by disabling one SIM: Temporarily disable one SIM in your phone settings and check which number or network disappears to identify it.

If you have a physical SIM and an eSIM, the eSIM is usually labeled separately in your phone’s settings.

For physical SIM cards, Mozillion SIMs fit all phones and come in standard, micro, or nano sizes. You can pop out the right size and insert it into the correct slot.

How do I locate my lost phone?

If you’ve lost your phone, you can use the built in tracking service on your device:

  • iPhone: Use Find My iPhone through Apple’s Find My service to see your phone’s location, play a sound, mark it as lost or erase it remotely.
  • Android: Use Find My Device through Google to see your phone’s location, play a sound, secure it or erase it remotely.
Can I get a free iPhone?
No, Mozillion does not offer free iPhones.
Can a deleted number be recovered from my call history?
Unfortunately, once a phone number is deleted from your call history, it cannot be recovered through Mozillion’s service. Call history data is stored on your device, so recovery would depend on your phone’s backup or recovery options rather than Mozillion.
Can I receive one-time password (OTP) text messages on my SIM?
Yes, you can receive OTP (One-Time Password) text messages with Mozillion service. Your Mozillion plan includes unlimited calls and texts within the UK, so OTP texts sent to your phone number will be delivered as normal.
Why can't I enter a competition by text message?
Mozillion does not allow entry to competitions via text message because bulk or commercial communications, including unauthorised messaging, are restricted under our responsible use policy.
How do I find my SIM PIN code?
