Only useful for people due for an upgrade with vodafone:
I was due for an upgrade with vodafone. I have been with them for past 2 years on a sim-only contract. I was pretty annoyed by their network and decided not to renew my contract. So gave them 1 month notice and just asked for a PAC code on webchat. I was instead transferred to their retentions team. I was not willing to listen to them at all as I was really annoyed by them but they just offered me a deal I couldn't resist.
I was offered a Samsung Galaxy S6 with no upfront cost - 3 GB Red value Data Bundle, unlimited texts and minutes for £16.80/month 24 mth contract. I was not convinced even then. They further offered me first 2 months for free.
So, the price comes down to £15.50 a month for a brand new Samsung Galaxy S6 32 GB with 3 GB data bundle which includes 500MB roaming data as well.
Anyone due an upgrade, should push for this deal if they fancy Samsung phones!! Cheers.
