Tell me about Sky Mobile - are they good?

[warmcosyblanket]

Need to change my phone, currently on O2. Their signal coverage is good in my area, and have discovered that Sky Mobile also use O2. They can offer me a deal which is about £200 cheaper on the phone that I want than I can get elsewhere. Is anyone with Sky Mobile and would recommend them, or otherwise?

I'm with Sky mobile (was with O2) and I have absolutely no complaints, big or small
I love that I can use my free Data piggy bank if I need extra one month and I can change my data package month by month via the app if I need too. I also use the free/no data used to stream TV/films either in this country or EU and the kids use it to watch films when on holiday.

I would recommend them OP
