Why am I unable to pay by mobile?

If your payment is failing this could be for a number of reasons:

  • You may have reached your spend limit, there is a £240 per month limit which is a legal requirement.
  • Your account may have been blocked (from third parties or premium charge numbers) by your Mobile Network Operator.
  • Are you an Android user? Android phones automatically block third-party messages, this can be changed in your settings on your mobile phone.
  • Your mobile network provider has not enabled mobile billing for this particular service.

To confirm if any of the above apply to your account please speak to your mobile network provider.

How was I subscribed to this service?

Firstly, you need to consider that you may not be subscribed to a service - you may have made a one-off payment (e.g. a donation to a charity or an entry into a competition).

However, if you have multiple payments to the same service, it is likely that you have a subscription.

Both subscriptions and one-off payments can be made in a number of ways:

  • You may have texted a keyword to a shortcode (5-digit number, e.g. 85525).
  • You may have tapped through 2 payment screens to confirm a payment whilst using your mobile phone.
  • You may have downloaded an app, set up an account and paid within the app.

To cancel a subscription, you will need to call the company providing the service, directly.

To find their contact details, enter the mobile number in the customer care search box, you will be provided with an overview of past transactions, with the name and contact details of the subscription you wish to cancel.

What is GDPR and why does it matter?

The General Data Protection Regulation is a regulation in EU law on data protection and privacy for all individuals within the European Union. The regulation ensures that individuals have control over their personal data. You can read a full explanation of Fonix’s compliance with GDPR on our legal page.

Due to GDPR, Fonix must not provide any information to a consumer verbally regarding the nature of charges on their mobile phone bill.

I have charges on my phone bill but it’s not showing up on your system, why is this?

If your charges aren’t showing up on our system, it’s either because:

  • The mobile number has been entered incorrectly.
  • It is another company that has charged you, not Fonix.
  • The charge was applied over 3 months ago.
