If your phone is lost or stolen please call us, on 0333 014 0333, and we will bar your SIM card.

If you know the IMEI number for your device, we can also bar the device, preventing your device from being used with any SIM from any UK network.

If you are using a phone that was provided by a different network operator it maybe be locked to that network and will need to be unlocked by contacting your previous provider.

The data settings may need to connect to the network may be missing. These can be sent to your device here.

To access voicemail dial 07782333123. Alternatively you can dial the short code 121 from your device.

If you are using your existing phone, make sure all previous voicemail numbers and diverts are deleted from your current phone memory to avoid any difficulties with your new voicemail service.

The transfer will generally take place anytime between 11am – 4pm, Monday to Thursday

If you try to use your old SIM in your device you will receive one of these messages ‘SIM registration failed’ or ”Network unavailable’. You may experience incoming calls on one SIM card and outgoing calls on the other SIM card as well as some downtime.

When you receive a ‘SIM registration failed’ or ‘Network unavailable’ message when using your old SIM, your number will have been transferred.

If you do not have an active service by 5pm on your transfer date, restart you device and if you still don’t have any service contact us on 0333 014 0333.

You will need to be in the UK on the day in order for the transfer to be successful.

We have a range of tariffs to suit any data requirement. Whether browsing or messaging, our data network will give you the speeds/connectivity you need. We also do not cut you off when you reach your threshold – instead an alert is sent letting you know you are reaching your limit.

We have a range of 4G-driven services that cover the whole gamut of business operations – from private APN services to Internet of Things and instant connectivity in new premises/outlets while a fixed line is being installed and then providing a back-up to that fixed line.

We are currently putting our 5G infrastructure in place and are discussing with our existing client base how their operations will benefit from 5G’s connectivity, speed and flexibility. It is important to plan now as 5G’s impact will be significant as it is rolled out nationwide.
