Two of the most enduring brands in the UK mobile market are being phased out from today, as EE is killing off T-Mobile and Orange to focus on selling its 4G services to new and existing customers.
Microsoft's low-cost Lumia 635 4G Windows Phone usually costs around $100, but it will be available for just $39.99 on Black Friday - even more affordable than the entry-level Lumia 530.
giffgaff has said that it is now "ready for a full scale launch of 4G", beginning on November 12, with three new goodybags, but there's still no unlimited 4G data option - 5GB is the most you'll get.
EE has introduced a tablet with integrated 4G LTE connectivity from £99.99 on pay-as-you-go, and is currently offering 100MB of free data every month to those buying a PAYG 4G tablet, phone or SIM.
Microsoft unveiled the Lumia 735 - its new 4G Windows Phone for the selfie-obsessed - a few weeks ago. Ahead of our full review, we look at some highlights of what the affordable handset has to offer.
Qualcomm is targeting the sub-$100 device market with its new Snapdragon 210 chipset, which includes 4G LTE connectivity and support for 1080p video playback, cameras up to 8MP, Bluetooth 4.1 and NFC.
A retailer is offering the Nokia Lumia 635 for just $79.99 off-contract, including free shipping, until September 4 - the lowest price we've seen so far for the new 4G Windows Phone 8.1 handset.
