Upcoming mobile network enhancement

Enhancement process

Good news, work is underway to enhance your mobile network, providing access to new and improved services.

The enhancement will improve your coverage indoors as well as outdoors, and improve device performance. Some of the new features are:

Great Population coverage
With 99% outdoor, 98% indoor and access to over 200 roaming destinations.

Voice over WiFi (VoWiFi)
Allows calls and texts to be sent over WiFi networks and works as a native dialler with no need to download an over-the-top application.

Voice over 4G (VoLTE)
Make and receive voice calls and texts over the LTE 4G radio network and extended call coverage into the 800MHz spectrum which travels further and deeper into buildings.

5G
Access to faster data throughput, lower latency, and greater device density, you have access to the 5G network with more spectrum than other UK networks.

What you need to do

On the enhancement date you have been provided, leave your device turned on overnight between 10PM and 8AM the following day.
WHY: The enhancement will not take place if you are not connected to the Gamma primary network. This means if you have your device switched off the enhancement will not take place.

If you will be roaming outside of the UK on your scheduled enhancement date, contact us to arrange an alternative date.
WHY: The enhancement will not take place if you are not connected to the Gamma primary network. This means if you are roaming outside of the UK the enhancement will not take place.

Ensure you listen to all your voicemail messages before 10PM on the enhancement date. After the enhancement you will need to set up voicemail again, including setting a pin and recording a greeting.
WHY: As part of the enhancement the voicemail platform is changing which means all saved and new voicemails on the old service will be deleted.

Set up call forwarding again following the enhancement
WHY: Any call forwarding, other than to voicemail, will be lost in the enhancement process and you will need to set them up again. Call forwarding can be added from your device settings menu or using the shortcodes:
To forward all calls: **21*[phone number]#
To forward calls if busy, unanswered or out of reach: **004*[phone number]#

You will receive a text or notification with the settings to re-activate data on your handset. Accept them when they arrive.
WHY: The upgraded network uses the data setting 'Gamma' (where previously it was ‘gamma.co.uk.’)

Your iPhone may have an existing settings profile. When you tap to install the new profile, your phone will guide you through deleting the existing profile and install the new one. Please delete the profile listed as “configuration profile” as the “downloaded profile” is the new one you need to install. The profile will not download if Safari is not set as your default browser. Either change your default browser to Safari before tapping on the settings download link or copy and paste the settings download link into safari.
