Welcome to Vodafone Community
I was looking for a Blackberry Key2 to replace my Key1, but it would appear that Vodafone does not stock any BlackBerry's on their pay monthly or pay-as-you-go plans.
Is this long term? I'm a business user and I imagine there are lots of us who will move away from Vodafone if they can't upgrade their blackberrys
Unfortunately BlackBerry has lost quite a bit of market share and interest and as such the network has made a business decision.
A.good place to watch is Vodafone > coming-soon.
Alternatives could be to use an independent such as CPW and or buy the phone of choice as a sim free option.
Current Phone > Samsung Note 9 _512Gb > Model: SM-N960 Hybrid-Duos.
